PLAINFIELD PARK DISTRICT - PRAIRE ACTIVITY AND RECREATION CENTER

The Plainfield Park District selected Wight & Company to design and build their new Activity and Recreation Center, located in Plainfield, IL. This is a 38,000 sq. ft. facility that includes a gymnasium, fitness center, preschool classrooms and supporting office areas. The design prioritized efficient building systems and a robust building envelope to achieve net zero energy.

Mechanical System Features

The mechanical systems for the building were designed to achieve optimal efficiency to obtain the net zero energy goal while staying within the owner’s budget. Different HVAC systems were evaluated in the early stages to determine which system best suits the needs of the project. The gym and the fitness area had limited options due to the occupancy/load type. It was decided to proceed with single zone VAV RTU for the gym and a multi-zone VAV RTU for the fitness and auxiliary spaces. The difference from the traditional RTUs was that the units were air sourced heat pump style RTUs. The choice of system that made most sense for the preschool/office area was between a traditional VAV system and a VRF/ERV system. Though the cost for a VRF/ERV system was greater than a traditional VAV system, the need for efficiency steered the final decision towards a VRF/ERV system.

The new HVAC system for the building includes the following:

Outside air needs for the preschool classroom and office areas are provided by an energy recovery ventilator (ERV). The unit preconditions the air via a total energy recovery wheel and then supplies it to the spaces. The unit utilizes a wheel with an efficiency of greater than 80%. The wheel operates using a VFD and has a purge option to make sure recirculation is minimized. The units are equipped with MERV 8 pre filters and MERV 13 final filters for proper IAQ. The densely populated areas have been provided with CO2 sensors that modulate the amount of OA as dictated by the CO2 levels.

The main heating and cooling for the preschool classrooms and office areas is provided by VRF cassette units. The heat recovery VRF systems allows for individual comfort control for each space. The condensing units for the system were located on the roof.

The gym is served by a single zone VAV RTU. The difference in this system is the use of an air sourced heat pump for heating as opposed to the traditional gas heat. The RTU is equipped with variable speed compressors, DX cooling, heat pump for heating, auxiliary heat via a modulating gas furnace, hot gas reheat, total energy recovery wheel (79% effective), VFDs for both supply and exhaust fan, and MERV-8/13 filtration. The hot gas reheat allows for humidity control in shoulder months, the auxiliary gas heat provides a backup source when ambient temperatures fall below threshold for air sourced heat pump operation and the MERV-8/13 filtration allow for proper IAQ. The space is furnished with a CO2 sensor that modulates the OA quantity for the space as dictated by the CO2 levels.

The fitness center and auxiliary spaces is served by a multi-zone VAV RTU. This unit is equipped with all the features similar to the gym RTU with the different being the downstream VAVs/FPBs. The spaces are served by a combination of variable air volume (VAV) boxes and fan powered boxes (FPBs). Each densely populated space served by a VAV or a FPB box is furnished with a CO2 sensor that modulates the OA quantity. All boxes are equipped with electric reheat.

Energy Efficiency

Energy efficiency was a top priority in order to achieve the net zero energy goal. The VRFs operate at 14 EER at full load and 24 IEER for part load and since most of the load curve falls in the part load category, very high efficiency is achievable. The use of air sourced heat pump RTUs allowed for high efficiency heating. Even at 0°F ambient the RTUs were able to achieve a COP of 2.4. Gas heat was still provided as an auxiliary source of heat when the heat pumps were not able to meet the load.

In addition to equipment the use of well-defined sequences allowed for efficient operation. Static pressure reset and discharge air temperature reset was implemented for both RTUs. However, the return air humidity sensor ensured that proper dehumidification as still achieved. The exhaust fans tracked the supply fan for the RTUs as opposed to operating off building pressure. This ensured that a proper quantity of exhaust air was passing through the wheel thereby taking full advantage by preconditioning the air.

Based on the energy model for the facility the average annual energy usage for the HVAC system designed is at least 37% lower than a conventional HVAC system utilizing ASHRAE 90.1-2013 compliant system. The building overall has a cost improvement over baseline of 27%, this does not include PVs.

Most of the energy savings in the building were achieved due to higher efficiency and proper operation of the systems. The other big push in energy savings came from interior lighting due to the use of high efficiency LED lighting, which was approximately 27% better than baseline.

Indoor Air Quality

The use of CO2 sensors allowed for the modulation of OA quantity as dictated by the CO2 levels in the space. This ensures a balance between energy usage for conditioning outside air and providing a quality indoor environment for the occupants. All units utilized MERV-8 pre filters and MERV-13 finals filters to further ensure proper IAQ for the building.

Innovation

Some of the innovative design features for the architectural, mechanical and electrical systems in the facility are:

The building is the first park district recreation center in the US to achieve PHIUS+ 2015 (Passive House Institute US) certification and also the first to receive PHIUS+ 2015 Source Zero certification.

All exhaust air from the facility is re-directed back to the ERV unit which is equipped with a total energy recovery wheel. This allowed for a much higher energy recover rate and contributed significantly to preconditioning the outside air.

The facility utilizes solar photovoltaic (PV) arrays on the entire roof of the building. The amount of PV arrays produces enough energy to offset the energy consumption of the building over the course of a year. This allows for the building to be net zero energy.

All the interior lighting is high efficiency long lasting LED. The lighting fixtures on/off functions are controlled by switches in series with dual technology occupancy sensors. The light levels for the interior lighting are controlled slide dimmers located on the walls. Exterior lighting is also exclusively LED. This includes the parking lot lighting, pedestrian lighting, park area

lighting, walk-way bollards and building mounted lighting. All the exterior fixtures are controlled by photocell. Lights can be turned off by timeclock or by photocell.

The building is majority daylight lit. Through sophisticated daylighting controls the facility turns off and modulates lights in response to the daylighting levels thus preserving natural light and saving lighting energy as required.

The building has tools for effective measurement and verification for all the utilized included electrical (sub metering for HVAC, lighting, and plug loads), gas usage and water usage that is accessible through the building BAS and through an energy dashboard to the general public.

Operation and Maintenance

The new HVAC system does not necessitate heavy maintenance. The ducted and cassette style VRF units have minimal maintenance, with washable filters changed by facility staff every 3 months. The RTUs have minimal maintenance as well, limited to filter changes and cleaning coils. All units utilize direct drive fans, so no belt replacement is necessary. The VRF condensing unit have low maintenance limited to fan motor replacement if needed and coil washing. Overall, the entire mechanical system can be maintained by someone with minimal knowledge of HVAC systems for efficient performance.

Cost Effectiveness

The goal to achieve net zero energy dictated using a highly efficient system but with the limited budget of the project the current system was chosen as it maintained a good balance between cost and efficiency.

Environmental Impact

Compared to a traditional VAV system utilizing ASHRAE 90.1 compliant packaged DX and gas heating RTU’s, VAV boxes for all spaces, the use of heat pump type RTUs and ERV/DOAS for the other areas allowed for more efficient system as demonstrated by the energy model. These energy saving have a direct impact on the carbon footprint of the building. The vast PV array on the roof further reduces this footprint by generation 100% of the energy consumed. This helps offsets all the site energy and the source energy as well.

A. SYSTEM DESCRIPTION1. A SPACE SERVED BY A SUPPLY AIR VAV TERMINAL UNIT WITH REHEAT COIL.

B. SEQUENCE OF OPERATION1. THE PRIMARY AIR DAMPER ON THE SUPPLY AIR TERMINAL UNIT SHALL MODULATE BETWEEN MINIMUM AND

MAXIMUM CFM SETTINGS AS SCHEDULED.2. THE SPACE TEMPERATURE SENSOR SHALL RESET THE DYNAMIC CFM SET POINT BETWEEN MIN/MAX CFM

SETTINGS ON THE SUPPLY TERMINAL UNIT TO MAINTAIN THE OCCUPIED COOLING TEMPERATURE SET POINT. UPON A RISE IN SPACE TEMPERATURE ABOVE COOLING SET POINT, THE PRIMARY AIR DAMPER SHALL MODULATE OPEN TO MAINTAIN THE DYNAMIC CFM SET POINT. UPON A DROP IN SPACE TEMPERATURE BELOW COOLING SET POINT, THE PRIMARY AIR DAMPER SHALL MODULATE TO MAINTAIN THE MINIMUM CFM SETTING.

3. PROVIDE A MINIMUM 5°F DEADBAND BETWEEN CONTROLLED HEATING AND COOLING SET POINTS WITHIN THE PROGRAMMING, ALL VALUES ADJUSTABLE.

4. UPON A DROP IN SPACE TEMPERATURE THE ELECTRIC REHEAT COIL SHALL BE ENERGIZED WITH THE SUPPLY CFM AT MIN. AS THE COIL REACHES THE MAX TEMPERATURE AND IF THE SPACE SETPOINT IS STILL NOT SATISFIED THE SUPPLY TERMINAL UNIT SHALL MODULATE TO THE MAX HEATIN CFM AS SCHEDULED.

5. THE EXHAUST TERMINAL UNIT SHALL TRACK THE ACTUAL SUPPLY AIR CFM TO MAINTAIN THE OFFSET CFM AT ALL TIMES. EXHAUST TERMINALS SHALL BE DUCTED TO EF-3. REFER TO SEQUENCE OF OPERATION FOR EXHAUST FAN EF-3.

6. THE SPACE TEMPERATURE SHALL BE MONITORED AND ALARMED. ALARM SETTINGS SHALL BE ADJUSTABLE OFFSETS ABOVE AND BELOW THE ACTIVE SET POINT, NOT FIXED VALUES. ALARMS SHALL BE DELAYED FOR FIVE MINUTES (ADJ.) BEFORE NOTIFICATION. THE ALARMS SHALL BE RECORDED IN THE ALARM EVENT LOG AND SENT TO THE OWS.

7. CO2 OVERRIDE CONTROLa. THE SPACE CO2 SET POINT (SET: 1100 PPM, ADJ.) SHALL BE MONITORED.b. UPON AN INCREASE ABOVE CO2 SET POINT, THE VAV UNIT SHALL SLOWLY MODULATE THE SUPPLY

DAMPER OPEN TO INCREASE VENTILATION RATE IN THE ZONE. THE DAMPER SHALL SLOWLY CLOSE WHEN THE CO2 READING DROPS BELOW SET POINT.

c. AN ALARM SHALL BE GENERATED IF THE VAV SUPPLY DAMPER IS FULLY OPEN AND THE CO2 READING REMAINS 100 PPM (ADJ.) ABOVE SET POINT. PROVIDE AN ADJUSTABLE DELAY (SET: 5 MINUTES, ADJ.) BEFORE GENERATING AN ALARM.

d. VAV SHALL MAINTAIN SPACE TEMPERATURE SET POINT DURING THIS MODE. OVERRIDE THE CARBON DIOXIDE CONTROL IF THE SPACE TEMPERATURE DROPS 3°F (ADJ.) BELOW SET POINT. RETURN TO NORMAL CO2 CONTROL WHEN SPACE TEMPERATURE IS WITHIN 3°F (ADJ.) OF SET POINT.
