High\Reports\Final\North Pole High Cover Letter V1.Docx

As a Technical Service Provider (TSP) to the Alaska Housing Finance Corporation (AHFC) under Task Order 4, NORTECH has completed an Investment Grade Audit (IGA) of North Pole High School in North Pole, Alaska. This work was funded by AHFC through the American Recovery and Reinvestment Act of 2009 (ARRA). Due to the scheduling requirements for completion of the IGAs and to provide a more thorough review of certain mechanical systems, NORTECH sub-contracted RS Consulting for the primary energy audit services for North Pole High School. RS Consulting is owned and operated by Ray Sneeringer, a licensed Mechanical Engineer in the State of Washington and most of the audit field work was completed by Sandra Edwards, a Certified Energy Manager (CEM) and owner of Edwards Energy Environmental and Waste Management. RS Consulting’s IGA methodology generally followed that outlined in the REAL Manual for an IGA. RS Consulting used Trane Trace 700 to model North Pole High School due to the more complex systems found in this facility. This report evaluates a few major EEMs and ECMs, which are generally consistent with NORTECH’s overall findings that FNSB SD facilities are well-maintained and well-operated with few areas for significant potential energy savings. While NORTECH agrees with the recommendations for the EEM/ECM packages, the cost estimates appear to be somewhat lower than expected from local vendors. Since the recommended upgrade(s) involve specific pieces of equipment and installation methods, NORTECH recommends the FNSB SD obtain project-specific quotes or bids from local vendors before approving the specific project. Due to rapid advancements of lighting technologies, project-specific lighting retrofits should be designed no more than six months prior to retrofitting in order to achieve the best technology and maximum savings. NORTECH believes some additional energy and cost savings may be achievable in particular areas of the building. The data necessary to evaluate these upgrades is outside the scope of work of this IGA, but could most likely be collected relatively easily using the mechanical system controls and/or some dataloggers. Specific areas that have the potential for additional energy and cost savings include:

1) Plug load retrofits (ex: replacing old refrigerators, placing vending machines on timers) 2) De-lamping areas of high foot-candles if lighting replacement isn’t performed 3) Domestic hot water generation and use (ex: low flow/automatic fixtures, solar water heating)

While this report differs from the format of other NORTECH reports produced for AHFC and the FNSB SD, NORTECH has reviewed the work of RS Consulting and determined this report is complete and accurately depicts the energy use of the building. Any future questions, comments, or correspondence regarding this report should be addressed to the undersigned. Sincerely, NORTECH

1.0 EXECUTIVE SUMMARY

Background

This energy audit report was prepared by RS Consulting and Edwards Energy Environmental & Waste Management in conjunction with NORTECH Sustainable Environmental Engineering, Health, & Safety for the Alaska Housing Finance Corporation. The North Pole High School is a 156,400 square foot facility located in North Pole, Alaska. The building serves 9th through 12th grade high school students and consists of classrooms, an auditorium, a gymnasium, administrative offices, and other miscellaneous support functions.

Scope

This Level II Energy Audit focused on the building’s envelope, lighting, and HVAC systems and consisted of an on‐site review of the existing facility, a review of the most current construction drawings, identification of potential energy efficiency measures (EEMS), creation of a computer simulation model to examine these EEMs, and a schematic level estimate of the installed costs and relative pay backs for each measure examined.

The Trane Trace 700 computer program was used to model the existing building’s energy consumption. The energy consumption values predicted by the model were then compared to actual energy consumption as shown in utility bills from 2009 and 2010. The computer model was then “tuned” to match the actual energy consumption as closely as possible.

Energy Use Index

Two years of utility bills were examined to determine the current energy consumption of the facility. The Energy Use Index (EUI) for this facility is 75 kBTU/SF. The chart below compares the existing and proposed EUI for the building with the EPA Energy Star design target value for a similar building in this location. This target value was developed using the Energy Star Target Finder software and represents the design criteria for a 50% Energy Star Rated Building, rather than the median value for existing K‐12 Schools.



Energy Consumption

The majority of the facility’s energy consumption can be attributed to the energy required to heat the outside ventilation air as it is introduced into the building. Any effort to conserve energy should start with an examination of the operation of the ventilation system.

Utility Costs

The annual utility cost predicted by the energy model for the existing building is $327,940. The estimated utility cost after implementation of the recommended Energy Efficiency Measures (EEM) is $307,110 for an annual savings of $20,830. A breakdown of the current and proposed energy costs is presented in the following charts:

Recommendations

We recommend implementation of a program to ensure that the operable windows remain closed during the heating season. The remaining original windows are failing and should be replaced in order to improve the performance of the building’s envelope. An inspection and monitoring the outside air dampers of each air handling unit should be performed in order to reduce the amount of outside air being introduced into the facility to current code minimums during cold weather and to eliminate the introduction of outside air into the facility during unoccupied hours.

We also recommend implementation of the Energy Efficiency Measures listed in the table below. Implementation of these measures should be accompanied by a more detailed Level III analysis which should include operational data logging, detailed engineering drawings and cost estimates, and a plan for future monitoring and verification of the performance of the installed measure.

2.0 INTRODUCTION

This energy audit report has been prepared by RS Consulting (RSC) and Edwards Energy Environmental & Waste Management (EEEWM) in conjunction with NORTECH Sustainable Environmental Engineering, Health, & Safety for the Alaska Housing Finance Corporation (AHFC). RSC and EEEWM audited North Pole High School in an effort to find cost effective opportunities to reduce building energy consumption. The Energy Conservation Measures (ECMs) and Energy Efficiency Measures (EEMs) analyzed in‐depth as part of the contract included several mechanical system improvements.

Two classifications of energy saving measures were examined during this energy audit. The first is a low cost or no cost solution designed to save energy by making changes to occupant activities, schedules, control set points, or small upgrades to existing equipment. This type of measure is identified in this report as an Energy Conservation Measure (ECM). The second type of energy saving measure requires significant capital investment to achieve energy savings. This is referred to as an Energy Efficiency Measure (EEM).

This Level II Energy Audit focused on the building’s envelope, lighting, and HVAC systems. A level II energy audit includes a survey of the building and a breakdown of the energy end uses within the building. This audit identifies and examines practical ECMs and EEMs to determine the potential energy savings realized if the measure is enacted. It also serves to identify potential improvements that may require the more thorough data collection and detailed engineering drawings and estimates which typically occur in a Level III audit. The scope of work for this audit consisted of an on‐site review of the existing facility, a review of the most current construction drawings, identification of potential Energy Conservation Measures (ECMs) and Energy Efficiency Measures (EEMs), creation of a computer simulation model to examine these EEMs, and a schematic level estimate of the installed costs and relative pay backs for each measure examined.

The audit team inspected the building during preliminary stages of the energy audit. The purpose of this field visit was to verify the configuration of the existing mechanical equipment and to assess its condition. Information was also gathered on the size and efficiency of the existing accessible mechanical system motors. A list of major mechanical equipment used in this facility can be found in Appendix F.

We also performed a review of the building envelope to identify any potential areas for possible improvement in energy performance and documented the type and number of lighting fixtures used throughout the facility to in order to identify opportunities to improve the performance of the lighting system.

Two years of utility bills were analyzed to determine the energy performance of the existing building in order to match the existing use with the use predicted by the computer model. Potential EEMs were identified and examined via the computer model or spreadsheet calculations. The predicted energy savings of these measures were then compared to the estimated installation cost to determine the relative pay back of each measure.

The Trane Trace 700 computer program was used to model the existing building’s energy consumption. The energy consumption values predicted by the model were compared to actual energy consumption as shown in utility bills from 2009 and 2010. The computer model was “tuned” to match the actual



energy consumption as closely as possible. This baseline was used to predict the energy savings realized by the proposed EEMs. The existing building energy use, as predicted by the computer model is shown in Figure 1.

Figure 1: North Pole High School: Energy Use by System

Heating energy comprises 65% (59% plus 6%) of the energy used in the school. This is consistent with the extremely low temperatures experienced during the subarctic winters in Fairbanks. This heating energy consists of an oil component, which is the oil used by the boilers and the domestic hot water generators, and an electrical component, which is the electricity used by the boiler’s ancillary equipment, such as the oil pump, the burner fan and miscellaneous electrical controls.

The cost of heating oil is significantly less than the cost of electricity per unit of energy ($.018/mbtu vs. $.052/mbtu) so although the heating system consumes 65% of the building energy, it represents only 45% of the total utility bills. Figure 2 shows the actual cost of the energy consumed by the facility.

Figure 2: North Pole High School: Energy Cost by System



The heating load consists of the heat lost across the building envelope and the heat used to warm outside air as it enters the building. This outside air is necessary to provide make up air for the building’s exhaust fans and ventilation air for the occupants. The breakdown of the total heat load of the school is shown in Figure 3.

Figure 3: North Pole High School: Building Heating Loads by Component

It can be concluded from the preceding charts, that efforts to conserve energy in the facility should begin with an examination of the ventilation air system. Please refer to Section 9.0 of this report for a more detailed discussion of this ventilation system.

Information in this study has focused on the areas of building envelope, lighting, and HVAC. Please reference subsequent sections of this audit report for detail information on the Energy Conservation Measures (ECMs), Energy Efficiency Measures (EEMs), calculation methodologies, and a summary of the findings and recommendations.

3.0 BUILDING DESCRIPTION

4.0 ENVELOPE

4.1 General

The building envelope is more than a polished exterior of glass, concrete and steel. The components utilized for controlling heat transfer, infiltration, stack effect, solar gain and humidity are vital for a high‐performance building. Insulated window or door panes whether it is single, double, or triple and “R” factors has an impact on the loads and efficiencies of mechanical and electrical systems. A cursory


July 30, 2012 Page 10

review of the existing building envelope and windows was performed to identify any areas which may benefit from replacement, new weather stripping, caulking and/or seals to prevent infiltration of outside air. This review included verifying the proper operation and alignment of windows and doors, checking for proper levels of insulation where accessible, and noting if any insulation was found to be damaged.

The Department of Energy has identified eight (8) climate zones for the United States. A list of counties and their respective climate zones can be found in American Society of Heating Refrigerating and Air‐Conditioning Engineers (ASHRAE) Advanced Energy Design Guide, and in the Department of Energy, Energy Efficiency and Renewable Energy VOLUME 7.1 Building America Best Practices Series. North Pole High School is a part of Zone 8 which means it is a part of the subarctic climate. A subarctic climate is defined as a region with 12,600 heating degree days (65° basis) or more. For this climate and to achieve over 30% above ASHRAE Standard 90.1‐1999, R values of between R13 to R60 are recommended depending on the type and the location of the envelope description. Window U‐values of .33 are recommended to exceed energy savings of 30% above ASHRAE standard 90.1‐1999. 4.2 Windows

The windows installed at North Pole High School are the original windows that were installed when the school was built in 1984. These inefficient windows are twenty‐eight (28) years old and are in need of replacement. Many of the window levers have been removed and some of the windows have been glued shut (Figures 4.2, 4.3, and 4.5). These levers were removed because many of the windows were being left opened. When the windows are left open, it causes the heating system to work harder and waste heat. These opened windows often short‐circuits the heating system where the thermostat thinks that it needs to heat the room, even though the heat is going out the window. Should an emergency arise where the only way to escape is through a window, it will be very difficult to exit the school if the windows are glued shut and the levers are removed. These problems may result in an increase in energy consumption, mechanical repairs, equipment replacement, and potential risk of life.

When a window breaks and a work order is submitted, the window maybe replaced with double or triple pane glass whatever is available. There is a combination of triple‐pane and double‐pane glass located throughout the school. Figure 4.6 is a typical example of a double and triple pane installation. This window is located on the second level near mechanical room 248. Condensation and air infiltration are caused at the school due to failure of the window seals. When a teacher accidently leaves a window opened one of the cleaning crew must shut it, and when the cleaning crew performs this task it places them in a precarious position which can be very dangerous because these wood trim windows are tilted outward.

The window films on these windows have deteriorated with age. The film is beginning to bubble. This is

very visible in several of the classrooms on the first floor (Figure 4.1 and Figure 4.4). Bubbling film is a

sign that the adhesive used to apply the tint to the window is failing. After a single bubble appears,

many more will follow. The original school was built with windows where the interior part of the

windows were made of wood and the exterior part of the windows were made of hollow metal frames

with 5/8” of rabbeted glazing with a thermal break and u‐value of approximately .50.


July 30, 2012 Page 11

4.3 Roof

North Pole High School Roof was replaced in 2009 under Project Number 06‐NPHPRJ‐2, IFB Number 08054. The roof insulation (R‐value) thickness is approximately R‐40 and is made of polyisocyanurate. Polyisocyanurate is rigid foam that provides continuous thermal insulation barriers for roofs. The advantages of using polyisocyanurate are the high R‐value and the good compressive strength. The disadvantage is the R‐value degrades over time. Larger R‐values have greater thermal resistance or more insulating potential than smaller R‐values.

4.4 Walls

Typical wall insulation at North Pole High School has an R‐value of approximately R‐36. The wall consists of 7/8“ Stucco, ½” plywood sheathing, 2” rigid insulation, 8” batt insulation, 2” rigid insulation, vapor barrier, and 2x8 @24” on center (oc).

4.5 Doors

Air leakage was evident around a few of the doors. There were ice and snow built up around some of the doors. Typical doors are 3’x7’x1¾” wood and hollow metal with ¼” wire‐glass glazing.

4.6 Recommendations

The following items should be implemented to improve the performance and operation of the building’s envelope: Window repair/replacement Behavioral changes/education to eliminate open windows during the heating season Replace worn and/or broken weather‐stripping around doors

Implementing these potential opportunities will have a holistic impact on mechanical and electrical systems through building envelope improvements. Investments in the building envelope will often add value to the buildings appearance.

Please refer to Appendix D for calculation of building envelope heat transfer properties.

5.0 LIGHTING

The most energy efficient lighting systems have already been installed, therefore no additional lighting upgrades are recommended for this facility. A detail study was conducted under Project # 09‐NPHPRJ‐1, IBF #11034. This detail study was completed in May 2011. The lighting upgrade retrofit project was implemented during the summer of 2011. Some of the most energy efficient state of the art lighting installed consisted of T5 fluorescent lamps and LED’s (reference Figures 5.1‐5.7). Information on this recent lighting upgrade is provided in Appendix C . Skylights are an excellent way to light the commons area and some corridors using natural light. Natural daylight provides free lighting and free heating. Lutron daylight sensors were installed during this lighting upgrade. These sensors are designed to harvest natural light and to maintain specific light levels in the space. The sensor automatically dims the lights when the available daylight is high and brightens the lights when the daylight is low. This sensor can control an individual fixture or a group of fixtures and can be programmed through the daylight sensor’s integrated infrared receiver. When the sun permits, the lighting energy consumption in these areas should be greatly reduced. We commend you on the LED lighting and the sensors that were installed during this recent lighting upgrade. The new lighting should impact the district’s operation and maintainence(O&M) in a very positve manner.

6.0 MECHANICAL

6.1 Air Handling Systems

North Pole High School is served by several air handling units located in second floor and penthouse mechanical rooms. The main classroom area is served by a variable volume air handling unit (AHU‐1). This air handling unit consists of an outside air /return air mixing plenum, a glycol heating coil and a variable speed plug type supply fan. The associated variable flow return fan (REF‐1) is equipped with a variable speed drive and is located in the same fan room. The return fan draws return air into the fan room and discharges it to the exterior. Both AHU‐1 and REF‐1 were originally provided with inlet vanes, which open and close in response to system demand to vary the flow of air from the constant speed supply fan. These inlet vanes have been locked in the open position and replaced with variable speed drives. Variable speed drives vary the speed of the fan to provide variable airflow to the building and consume less energy than the original inlet vanes. Please refer to Drawing M1.2 in Appendix E for a diagram of this system.

The Music Area is served by AHU‐2 and REF‐2. These are similar to the units described above (AHU‐1 and REF‐1), except the original inlet vanes are still in operation. Both AHU‐1 and AHU‐2 provide air to individual terminal units at each classroom or temperature control zone. The terminal units do not have heating coils and heating is provided by hot water finned tube units on the perimeter and supplemented

by warm air delivered by the main air handling unit.

The auditorium, gymnasium, and locker rooms are served by individual air handling units (AHU‐3, AHU‐4, and AHU‐5). These AHUs have an outside air /return air mixing plenum, a glycol heating coil and a two speed, two motor supply fan. The supply fan switches between high speed and low speed depending on the load in the space. At low speed, the smaller, low rpm motor runs and at high speed, the larger high rpm motor runs. Please refer to Drawing M1.3 in Appendix E for a diagram of this system.

There are also several heat recovery loops utilized in the building. Each loop is a run‐around heat recovery loop which uses a glycol mixture and pump to transfer heat from the exhaust air stream to the incoming outside air. Heat is recovered from the toilet room, locker room and shop exhaust systems. Refer to drawing M1.4 in Appendix E for a diagram of this system.

Figure 6.2 – Typical Air Handling Unit

Figure 6.1 – Inlet Vanes on REF‐1

6.2 Heating Systems

Three Weil McLain oil fired cast iron sectional boilers provide heat for the facility. These boiler and their associated pumps are located in a ground floor mechanical room. The boilers are piped in a series configuration. This means the output of the first boiler is mixed with the system flow before it enters the second boiler, and the output of the second is mixed with the system flow prior to entering the third boiler. Each boiler raises the temperature of the system flow approximately 14 degrees F.

A constant volume pump distributes heating water to various mechanical rooms. At each mechanical room, this water is utilized in one of three ways:

1) Passed through a glycol to hot water heat exchanger via a manual balancing valve to generate hot glycol for use in the outside air preheat coils.

2) Mixed with return water and distributed to hot water coils in the AHUs via individual coil pumps and three‐way valves.

3) Pumped to fin tube perimeter heating units via a single pipe “mono‐flo” system through two‐way valves.

Please refer to Diagram M1.1 in Appendix E for additional information on the heating water distribution system.

July 30, 2012 Page 17

6.3 Control Systems

The majority of the mechanical systems are controlled by a Johnson Controls Metasys direct digital control (DDC) system. This system was substantially upgraded in 2000. The DDC system starts and stops the mechanical equipment, controls space temperature and maintains the proper amount of outside air flow to accommodate the occupant load at any given time. Outside air control is accomplished with the use of CO2 monitoring. The level of CO2 in the sampled air is an indicator of the number of occupants in the building. The DDC system adjusts the outside air dampers to maintain the CO2 levels at the set point value. The control of ventilation air based on actual space occupancy is known as Demand Controlled Ventilation (DCV) and can be a very effective way to conserve energy by reducing the amount of outside air introduced into the building.

6.4 Domestic Hot Water

Domestic hot water is generated by three oil fired hot water heaters with combination storage tanks. These are located in the Boiler Room.

6.5 Mechanical System Trend Logs

With the assistance of FNSB personnel, the operating parameters of a single air handling unit and the heating water system were monitored and recorded over a period of several days. This period included weekday and weekend operation. The intent of monitoring a select group of points was to determine if the operation of the mechanical systems was consistent with the assumed schedules and operating parameters used in the computer simulation model, and to identify any potential energy saving items that may be candidates for more in depth monitoring and analysis in the future. This data (typically referred to as a trend log) was taken for AHU‐1, which serves the main classroom and administrative areas. Observations for AHU‐1 may or may not apply to the other units that were not monitored. Certain sections of the trend data were graphed to illuminate items of interest that were noted in our review of the data collected. The data points that were monitored during this study were a small selection of the total number of points available for monitoring in the future. Since only a small selection of points were monitored it should be noted that while we were able to calculate the percentage of outside air from the trend logs, we were not able to determine the total amount of outside air because the total fan airflow is not known. AHU‐1 is a variable air volume system, so the total airflow of the system will vary in response to the opening and closing of the terminal units serving individual zones.

The following observations are from our analysis of the trend logs:

The supply fan started at 6:00 am and the outside air percentage at this point is around 12% At 10:00 am the outside air percentage jumped to 35%, indicating that the DCV control is

responding correctly to a buildup of CO2 from the occupants. At 3:00 pm the outside air damper closed The supply fan continued to run since the outside air temperature was below minus 20. The outside air dampers did not close fully during this time and approximately 6% of the air

introduced into the building was outside air.


July 30, 2012 Page 18

In addition, the operation of the boiler plant was monitored for the same time period. Analysis of the boiler plant trend logs shows that the load on the boiler plant peaks when the outside air dampers are opened, as expected, but the load during the unoccupied hours (when the outside air dampers should be closed) is still fairly substantial. Control of the boiler leaving water temperature is not stable and this is causing the system temperatures to hunt. During one four hour period on Jan 14th, all boilers were enabled, yet the system temperature difference varied from between 7 degrees and 17 degrees several times. Typical variations would be expected to be in the range of 3‐5 degrees for this type of operating scenario. Fluctuating leaving water temperature will cause the heating water valves located at the air handling units to become unstable and may lead to excessive energy consumption. Based on our review of trend logs for AHU‐1 and the boiler system, we have the following recommendations:

Visually inspect the outside air dampers at each air handler to ensure that they are fully closed during unoccupied hours.

Inspect the control system and sequences related to the heating water supply temperature control to determine if the control loop can be tuned to reduce the variations in supply water temperature.

A graphical representation of the operation of AHU‐1 and the boiler plant is included in Appendix I.

7.0 ENERGY USE

The purpose of this energy audit is to identify measures or practices that will result in a reduction in the energy use of the facility. Fuel oil is used for building heating and domestic hot water generation, while electricity is used by fans, pumps, lights, and miscellaneous plug loads.

A reduction in oil use can be achieved by one or more of the following actions:

Reduce the amount of ventilation air being introduced into the building

Reduce the amount of heat lost through the envelope of the building.

Recover heat before it is exhausted from the building.

Improve the efficiency of the oil burning equipment.

A reduction in electrical consumption can be achieved in one or more of the following manners:

Improve the efficiency of the lighting systems.

Vary the speed of fans and pumps in response to the building loads.

Improve the efficiency of the motors.

Turn off systems when they are not required.

Two years of utility bills were analyzed to determine the energy consumption characteristics of the facility. These numbers were then normalized to account for any unusual weather conditions that may


July 30, 2012 Page 19

have occurred during the span of the two years. For example, if the winter of 2010 was abnormally warm, the yearly energy consumption would be less than that of a typical year. The number of actual heating degree days (HDD) for each month during the two year time period was compared to the historical average heating degree days for that month, and the oil consumption use was adjusted based on this ratio. These adjusted energy consumption values were then used to calculate an overall building energy use index. The calculated Energy Utilization Index (EUI) for this facility is 75 kBTU/SF. The EUI calculation is included in Appendix A. Figure 7.1 shows a comparison of the existing and proposed EUI with both the average EUI found in the building operated by the Fairbanks North Star Borough and the Environmental Protection Agency’s Energy Star rating for a median building of a similar type. This target value was developed using the Energy Star Target Finder software and represents the design criteria for a 50% Energy Star Rated Building, rather than the median value for existing K‐12 Schools.

8.0 ENERGY MEASURES

8.1 Types of Energy Savings Measures

Potential energy saving measures (ECMs and EEMs) were identified for the facility based upon an on‐site

inspection, a review of utility records, computer modeling and interviews with facility personnel. The

purpose of identifying these energy measures is to reduce energy consumption, and lower operational

costs.

Each measure was analyzed either by utilizing a spreadsheet calculation or by employing the TRACE energy‐modeling program. A rolling baseline modeling system is employed during the modeling process. This system analyzes each alternative based on the results of the previous alternative. The first alternatives analyzed are the ones thought to be most likely to result in a short payback period. The rolling baseline system is used to prevent double accounting of energy savings. For example, if one


July 30, 2012 Page 20

alternative improves the building envelope and the following alternative increases the efficiency of the heating system, the second alternative must take into account the decreased heating load provided by improving the envelope in the first alternative. If this reduced heating load is not taken into account, the second alternative would show additional heating energy savings that would not be realized in a building with an improved envelope.

The following measures were analyzed for this facility:

8.1.1 Energy Conservation Measures:

ECM A – Ventilation System Optimization

ECM B – Replacement of Existing Motors with More Efficient Motors

8.1.2 Energy Efficiency Measures:

EEM 1 – Replace Inlet Vanes with Variable Speed Drive on AHU‐2

EEM 2 – Variable Speed Pumping

A more thorough discussion of each ECM/EEM can be found in Section 9.0.

8.2 Computer Modeling

The TRACE building modeling system examined three alternatives:

8.2.1 Trace Model Alternative One: Baseline Building

This alternative models the existing facility using information from the most current as built drawings, as well as information gathered during our field visits. The existing wall and roof u‐values were calculated and input into the model. The existing lighting densities, HVAC system types, airflows and operational schedules were used. The energy use predicted by the baseline model was then compared to the actual utility bills (normalized to reflect an average year) to determine if the model was accurately describing the operation of the existing facility. The model was then “tuned” to follow the existing building energy consumption as closely as possible.

8.2.2 Trace Model Alternative Two: Replace Inlet Vanes with Variable Speed Drives

This alternative examines EEM‐1, locking the existing modulating inlet vanes in the open position and adding variable speed drives to control the speed of the existing variable air volume fans serving the Music and Drama Departments (AHU‐2).

8.2.3 Trace Model Alternative Three: Variable Speed Pumping

This alternative includes all the energy upgrades proposed in Alternative Two, and examines EEM‐2, variable speed pumping for the main heating water distribution pumps.

The TRACE 700 computer model input and output data is included in Appendix G and H respectively.

8.3 Energy Costs

The following energy costs were used in this analysis:

Fuel Oil = $3.40/Gallon Electricity Consumption = $.156 per Kwh Electrical Demand = $10.79 Kw Blended Electrical Rate = $.177 per Kwh

9.0 ENERGY MEASURE DESCRIPTIONS

9.1 ECM A – Ventilation Air Reduction

Heating of the outside ventilation air is the primary source of energy use for the facility. Any actions taken to reduce the amount of ventilation air introduced into the building will save a significant amount of energy.

A certain amount of fresh air is required in order to provide adequate indoor air quality, but excessive amounts of outdoor air lead to increased energy consumption. This delicate balance between indoor air quality and energy consumption is perhaps the most important aspect of any energy conservation project.

The 2009 International Mechanical Code stipulates the minimum outside air requirements for any facility. These requirements include a people component and an area component. For each particular use, the code specifies a cubic foot per minute of outside air per each occupant (cfm/person) and an amount of outside air required based on the square footage of the space (cfm/square foot). Codes that were in place during the design of this facility typically only included a people component. The 2009 IMC reduces many of the cfm/person requirements from the original codes in place during the time construction of this facility. However, some of the requirements for classrooms have actually increased. Depending on the balance of classroom to other uses, implementation of the new code may either increase or decrease the total required amount of outside air for a particular facility. An excerpt from the current code is listed below:

If the air handling system provides ventilation air to multiple zones, then several additional calculations must be performed to determine the fraction of outdoor required at the air handler. These calculations provide correction factors for over ventilated zones, air distribution effectiveness and system efficiencies. A calculation of the overall percentage of outside air required at each air handler can be found in Appendix D.

North Pole High School utilizes CO2 sensors in the return air ducts to monitor the ambient CO2 level. The control system modulates the amount of outside air introduced in the building in proportion to the number of people in the space at any given time. This is known as demand controlled ventilation (DCV) and is the best method to balance the need for adequate indoor air quality with the desire to reduce energy consumption.

Demand Controlled Ventilation (DCV) is a method of adjusting the amount of outside ventilation air introduced in to the building based on the number of occupants at any given time. The number of occupants can be determined indirectly by measuring the concentration of carbon dioxide (CO2) in the air. Each person produces CO2 at a fairly constant rate, therefore the concentration of CO2 in the return air system can be used as an indication of the number of people occupying the space.

Measuring the return air CO2 is a relatively inexpensive method of DCV since it requires only one sensor and minimal control wiring. However, this method provides an average reading of all the spaces served by the system. If one space is fully occupied and the other is empty the average value read in the return air stream will not be indicative of what is actually happening on a room by room level and some zones may be over ventilated, while others are under ventilated.


July 30, 2012 Page 23

The control system monitors the CO2 level in the return air stream and opens the outside air damper when this level exceeds a certain set point. This set point is based on a calculation of the minimum amount of outside air required by code. The calculation of the maximum allowable CO2 level is provided in Appendix D. This CO2 set point should be compared to the current set point and adjusted, if possible, to reduce the amount of outside air required.

The facility’s air handling units are scheduled to run during unoccupied hours any time the outside air temperature drops below minus 20 degrees F. The temperature in Fairbanks is below minus 20 degrees between the hours of 5 PM and 8 AM (unoccupied hours) for approximately 550 hours per year. The control systems are set up to allow a small percentage (approximately 5%) of outside air into the building during these times in order to keep the building pressurized and prevent any infiltration of cold air. This outside air used for pressurization must be heated prior to entering the building. The heating of this outside air represents an annual energy cost of approximately $2 per cubic foot per minute (cfm) of outside air. For example, if AHU‐1 is bringing in 3000 cfm (5%) of outside air, this would result in an annual energy cost of $6,000.

Although this pressurization of the building may be required to prevent freeze up and maintenance issues when the outside air temperatures drop below minus 20 degrees, it does require a substantial amount of energy to heat the outside air used to pressurize the building. We recommend revisiting this practice to determine if the buildings can be operated with little or no outside air (neutral pressure) during this time in order to reduce the overall building energy consumption.

We also recommend a visual inspection of all the outside air dampers in the facility to verify that they are closing properly during unoccupied hours. Also, the seals on these dampers should be inspected to verify that the damper is not leaking when it is closed.

9.2 ECM B – Energy Efficient Motors

The pay back derived from replacing existing electric motors with premium efficiency motors depends on the horsepower, the existing motor efficiency, the hours of operation, the type of system and the location of the existing motor. Larger motors tend to provide lower pay back periods. The tables included in Appendix D provide information on the typical motors used in this facility and indicate the existing motor efficiency at which the payback period becomes feasible. For example, if an existing 10 horsepower motor used in a perimeter heating loop has an efficiency less than 87.5%, then replacing the motor with a premium efficiency model will provide a payback of approximately 5 years. Motors used in variable speed systems will have a longer payback than indicated in the charts because the motor is not operating at full design horsepower for the number of hours indicated. Additionally motors located in the airstream of fan systems will also have a slightly longer payback, because the heat produced by the inefficiency of the motor is used in a beneficial way during the heating season. Please refer to the tables to determine the feasibility of replacing other motors used throughout the facility. Since many of the motor nameplates are obstructed or could not be found, a simple payback calculation for each motor is not feasible. However, as maintenance personnel are working in this building, this chart can be used to determine if the motors should be replaced or re‐used.

9.3 EEM 1‐ Add Variable Speed Drives to AHU‐2 and REF‐2

The original design of the variable air volume fans included using modulating vanes on the inlet of each fan to vary the amount of air produced by the fans by changing the angle of air as it hit the fans blades. The fans run at full speed but total horsepower required decreases as the motor unloads. This technique saves energy but is not as efficient as simply slowing down the speed of the fan blade by using variable speed drives. This EEM includes the following: Remove inlet vane controller and lock inlet vanes in the open position on AHU‐2 and REF‐2. Provide new variable speed drives for each fan motor. Extend the existing DDC control system to incorporate these new points.

9.4 EEM 2 ‐ Add Variable Speed Drives to the Main Heating Water Distribution Pumps

The main heating water distribution system serves several different heating water systems throughout the building. One of which is the heat exchangers that serve the glycol heating water distribution systems. Manual balancing valves currently control the main system heating water flow that passes through these heat exchangers. This results in a constant flow of heating water through the system even if there is not a demand for heating. This alternative includes the following work: Replace the manual balancing valves on the

water to glycol heat exchangers with electric 2‐ Way control valves.

Replace 3‐Way valves on coil pumps with 2‐Way Valves for AHU‐1, AHU‐2, AHU‐3 and AHU‐4.

Provide new variable speed drives for each pump motor.

Extend the existing DDC control system to incorporate control of the drives based on system pressure.

This measure will reduce the system pumping energy by varying the heating water flow in response to the actual building heating loads. Refer to Drawing M.1A in Appendix E for a diagram of the proposed changes.

10.0 SIMPLE PAYBACK AND SIR

The total energy saved by employing Energy Conservations Measures ECM‐A, Ventilation Air Reduction and ECM‐B, Energy Efficient Motors, could not be calculated. Calculation of the total energy saved from implementing ECM‐A requires detailed data monitoring and analysis of each individual air handling system in order to determine the existing energy consumption of each unit. Calculation of the total energy saved by employing ECM B could not be performed since many of the motor nameplates were inaccessible or missing during our walkthrough. This level of detailed analysis is beyond the scope of a Level II audit and is typically performed during a Level III Audit. Therefore, simple payback and Savings

Figure 9.1 – Typical Coil Pump and

to Investment Ratio (SIR) calculations are not presented for the recommended Energy Conservation Measures (ECMs).

The simple payback and SIR were calculated for each of the Energy Efficiency Measures (EEMs) studied in this report. The estimated installed cost for each proposed energy efficiency measure (EEM) was compared to the estimated energy savings to provide a relative comparison of each measure.

The simple payback calculation is a quick method of comparing various EEMs but does not take into account the time value of money or the costs or savings beyond the first cost.

The savings‐to‐investment ratio (SIR) is the ratio of the present value savings to the present value costs of an energy conservation measure. The numerator of the ratio is the present value of net savings in energy plus or minus any additional maintenance costs related to the measure. The denominator of the ratio is the present value of the installation cost of the measure.

The following formulas were used in the calculation of each ratio:

Simple Payback = Cost of Energy Saved/Cost of Installation of EEM

SIR = Present Value of Energy Saved for the Life of the Measure/Present Value of the Installed Cost

11.0 OPERATIONS AND MAINTENANCE

A successful operations and maintenance plan is the key to continued energy savings in any facility. According to the American Society of Heating and Refrigeration Engineers (ASHRAE) 2007 Handbook, the original design and installation of a mechanical system constitutes only around 10% of the total life cycle cost, while operation and maintenance costs represent approximately 80% of the total cost over the life of the system. The remaining 10% of the life cycle cost is attributed to acquisition, renewal and disposal.

When a mechanical system is installed, it should be commissioned to ensure that the operation of the system meets the design intent. Over the life of this system, its operation should be verified via control system trending and/or field measurements. If the system is found to be operating outside of the original design intent, corrective action or retro commissioning should be initiated.


July 30, 2012 Page 26

A quality preventative maintenance plan can extend the life of the mechanical system beyond the estimated service life of the equipment and free up capital funds for other projects. Frequent filter changes can result in significant energy savings over the life of the building. The pressure drop across the filter increases as it captures dirt and dust. This increased pressure drop results in additional energy consumption, a decrease in airflow, or both. For a typical 20,000 cfm fan system a 1” static pressure increase will result in an increased annual energy cost of $2000.

The level of maintenance at the North Pole High School appears to be excellent. The level of quality of the installed Pace custom air handlers is very high, and there were no visible signs of wear or of any maintenance problems. The mechanical spaces are clean and well kept and the filters appear to have been changed frequently.

12.0 RECOMMENDATIONS

The lighting systems at North Pole High School have been recently upgraded, therefore, no additional lighting measures are recommended for this facility. The current windows are 28 years old and are beginning to fail. Several have been replaced with more energy efficient windows as they have failed and several have had only the glass contents replaced. We recommend replacing the remaining original windows to decrease the infiltration of cold air and to improve the thermal performance of the building envelope. We also recommend implementation of an education and monitoring program to ensure that the windows remain closed during the heating season. In addition, we recommend further analysis of the following Energy Conservation Measures: ECM A Ventilation Air Reductions

Verify that the maximum CO2 set points used in the Demand Controlled Ventilation (DCV) control scheme are in agreement with current codes. It is possible that some of the set points may be increased, which will reduce the amount of outside air needed.

Revisit the practice of pressurizing the building in cold weather during unoccupied hours. This practice may be required to prevent freeze up or damage, but any reduction in the amount of pressurization required will result in substantial energy savings.

Inspect and repair all outside air dampers that may be leaking or not closing properly to prevent introduction of un‐wanted outside air during unoccupied hours.

The majority of the facility energy use can be attributed to the heating of the outside air as it is introduced into the building. Therefore, anything that can be done to reduce this outside airflow will have the greatest impact on the overall energy consumption of the facility.


July 30, 2012 Page 27

ECM B Replace Low Efficiency Motors Where Applicable

Replace motors that do not meet the minimum efficiency criteria as listed in the Table provided in Appendix D.

We recommend implementation of the following Energy Efficiency Measures: EEM 1 Add Variable Speed Drives to AHU‐2 and REF‐2

The variable volume fans serving AHU‐2 and REF‐2 are currently controlled by inefficient inlet vanes. Replacing these inlet vanes with variable speed drives will reduce the overall fan energy consumption.

EEM 2 Variable Speed Pumping on the Main Heating System Electrical energy consumption will be reduced significantly by converting the existing constant volume heating water pumps located in the main boiler room to variable volume pumps.

Building Envelope - Calculations and Common Conversions • U-Value = 1/R-Value • R-Values per Inch of Common Insulation Materials Fiberglass Blanket 3.2 Loose Fiberglass 2.5 Fiberglass Blown-in-Bat 4.0 Loose Rock Wool 2.8 Loose Cellulose 3.5 Wet-Spray Cellulose 3.9 Vermiculite 2.7 Polyisocyanurate 5.8 Expanded Polystyrene (bead board) 3.8 Extruded Polystyrene (blue board) 4.8 Foil Faced Polyisocyanurate 7.0 Spray applied Foam 6.0 U value = btu’s/ Hour x sq ft x deg F = 1/R R value = Hours x sq ft x deg F / BTU’s= 1/U q (Building heat loss in btu’s/hr)= U x A x Delta T = U x A x DD x 24 (annual heat loss)

Sample Calculations: Building Envelope-Heat Transfer Calculations R- “Resistance value” of building materials to heat flow RT = R inside film + R1 + R2 +… R outside film U-value: “overall heat transfer co-efficient” (Includes allowance for BOTH convection and conduction heat transfer) U = 1/ RT Sample Calculation 1: Windows: window area is 1000 square feet Window is triple pane; U = .27 Q = A * U * (Ti – To) Where Q = Total hourly rate of heat loss through walls, roof, glass, etc in Btu/hr U = Overall heat-transfer coefficient of walls, roof, ceiling, floor, or glass in Btu/hr ft2°F A = Net area of walls, roof, ceiling, floor, or glass in ft2 Ti = Inside design temperature in °F = 70 To = Outside design temperature in °F = 30 Q = U * A * delta T = .27 x 1000 x (70 – 30) = .27 x 1000 x 40 = 10,800 Btu/hour

Sample Calculation 2: For sample calculations- outside design = 30 F, inside design = 70 F Walls: wall area is 1000 square feet Wall is wood stud with R-30 insulation; U = 0.033 Q = U x A x delta T = 0.033 x 1000 x (70 – 30) = 0.033 x 1000 x 40 = 1333.3 Btu/hour Radiation heat gain thru windows Q = (A) x (SHGF) x (CLF) x (SC) Where: Q = heat transfer in BTU/HR A = window area in ft2 SHGF= solar heat gain factor (dependent on orientation and location) CLF = cooling load factor (dependent on shading and color of interior surface) SC = shading coefficient (property of glazing; dependent on clear/tinted/mirror glass surface) Other ratings- SHGC = solar heat gain coefficient = SC x 0.86 Glazing selection – Single pane vs. dual/triple pane Single pane- “U” = 1.10 Dual pane- “U” = 0.35 Triple pane- “U” = 0.22 (NOTE effect of interior “films” at glass surfaces; insulation value increases due to air space and number of surface films) – “low E” glass coating that allows light to get thru but not heat Glazing Selection SHGC- Solar Heat Gain Coefficient (% of ALL radiation (UV, visible and IR) that gets thru glass) VT- Visible Transmittance (% of visible light that gets thru glass) SOUTH FACING GLAZING: – Cold climate: SHGC > 0.6; high VT; low “U” – Moderate climate: SHGC < 0.6; high VT; low “U” – Hot climate: SHGC < 0.4; medium VT; low “U” – East/west facing: SHGC < 0.4; high VT; low “U”

CO2 Calculations

Cru - C0 = 1,000,000 x Nb x M / Ros Calculates rise in CO2 concentration if all supplied outdoor air is consumed.

Cs-C0 = Zs x 0 + (1-Zs) x (Cru - C0) Calculates target SA CO2 concentration (above ambient) based on previous calculation.

Cru = CO2 concentration in recirculated air if all outdoor air supplied to the building is used.

C0 = CO2 concentration outdoors.

Nb = CO2 generation rate per person at base metabolic rate. Default = 0.0091 CFM/Person (0.0043 L/s per person).

M = Relative metabolic rate in met units. Default is sedentary person = 1.2 mets, ASHRAE standard 62.1-2007, Appendix C.
