This section ocuses on a major building strategy that coversseveral LEED credits. This strategy yields 8 - 32 LEED points.

This strategy involves installing a hydronic heating and cool-ing system in place o a central air system or multiple through-the-wall units, which are the current industry standards. Whilehydronic systems tend to have higher up ront costs, they aremuch more energy e cient than other systems and quicklypay back their initial investment. This makes them an excellentchoice both rom a nancial and an environmental perspec-tive. Also, hydronic systems are extremely well-suited to takingadvantage o renewable energy sources, improving the per or-mance and lowering the energy costs even urther.

One o the principal components o the hydronic system isthe piping. We recommend using Aquatherms Climathermline or heating and cooling distribution because Climathermis the highest per orming, most cost-e ective, and most envi-ronmentally- riendly solution in the industry. The Climathermpipes are smooth and naturally insulated, minimizing both heatloss and wasted pump energy. And they are not a ected by thecorrosion, scaling, and abrasion that damages metal systemsover time. Climatherm also operates more quietly than othercomparable systems, adding to the com ort o the buildingsoccupants.

Climatherm is highly resistant to rost damage and chemicalleaching, making it sa e to bury directly in the ground. Thisallows the ground-source energy to be carried directly into thebuilding without having to trans er through several types o systems and risk mechanical ailure.

Climatherm piping systems generally last longer and requireless maintenance in hydronic applications than other systemsdo. This helps ensure that the system realizes its ull cost bene tduring its li ecycle. Its also better or the environment becauserepairing and replacing a ailed system consumes a great dealraw materials and regenerates all the initial production pollu-

tion.

In short, Climatherm piping systems are the best choice orhydronic distribution, and a hydronic heating and cooling sys-tem is the best choice or LEED.

Major Strategy: Hydronic Heating and CoolingEA Credit 1: Optimize Energy Per ormance 2

119 Points

Intent To achieve increasing levels o energy per ormance beyond theprerequisite standard to reduce environmental and economicimpacts associated with excessive energy use.

Requirements

Select 1 o the 3 compliance path options described below.Project teams documenting achievement using any o the 3options are assumed to be in compliance with EA Prerequisite2: Minimum Energy Per ormance.

OPTION 1. Whole Building Energy Simulation (119 points)

Demonstrate a percentage improvement in the proposedbuilding per ormance rating compared with the baselinebuilding per ormance rating. Calculate the baseline buildingper ormance according to Appendix G o ANSI/ASHRAE/IESNAStandard 90.1-2007 (with errata but without addenda 1) usinga computer simulation model or the whole building project. The minimum energy cost savings percentage or each pointthreshold is as ollows:

Appendix G o Standard 90.1-2007 requires that the energyanalysis done or the building per ormance rating methodinclude all the energy costs associated with the buildingproject. To achieve points under this credit, the proposeddesign must meet the ollowing criteria:

Compliance with the mandatory provisions (Sections5.4, 6.4, 7.4, 8.4, 9.4 and 10.4) in Standard 90.1-2007(with errata but without addenda).

Inclusion o all the energy costs within and associatedwith the building project.

Comparison against a baseline building that complieswith Appendix G o Standard 90.1-2007 (with erratabut without addenda). The de ault process energy costis 25% o the total energy cost or the baseline building.I the buildings process energy cost is less than 25% o the baseline building energy cost, the LEED submittalmust include documentation substantiating that pro-cess energy inputs are appropriate.

For the purpose o this analysis, process energy is considered toinclude, but is not limited to, o ce and general miscellaneousequipment, computers, elevators and escalators, kitchen cookingand re rigeration, laundry washing and drying, lighting exempt

rom the lighting power allowance (e.g., lighting integral tomedical equipment) and other (e.g., water all pumps).

Regulated (non-process) energy includes lighting (e.g., or theinterior, parking garage, sur ace parking, aade, or buildinggrounds, etc. except as noted above), heating, ventilating, andair conditioning (HVAC) (e.g., or space heating, space cooling,

ans, pumps, toilet exhaust, parking garage ventilation, kitchenhood exhaust, etc.), and service water heating or domestic orspace heating purposes.

For this credit, process loads must be identical or both the

baseline building per ormance rating and the proposed build-ing per ormance rating. However, project teams may ollowthe exceptional calculation method (ANSI/ASHRAE/IESNAStandard 90.1-2007 G2.5) to document measures that reduceprocess loads. Documentation o process load energy savingsmust include a list o the assumptions made or both the baseand proposed design, and theoretical or empirical in ormationsupporting these assumptions.

Projects in Cali ornia may use Title 24-2005, Part 6 in place o ANSI/ASHRAE/IESNA Standard 90.1-2007 or Option 1.

1 Project teams wishing to use ASHRAE approved addenda or the purposes o this credit may do so at their discretion. Addenda must be applied consistently across all LEED credits.

Relevance o Aquatherm to the LEED Credit

The heating and cooling system in a commercial or residentialbuilding represents a large portion o a buildings total energyusage: roughly 40 to 45%. Improving the e ciency o the heat-ing and cooling system will dramatically reduce overall energy

usage.

Hydronic heating and cooling systems are more e cient thanPTAC or central air systems. As a result, they have lower operat-ing costs and energy demands. Using Aquatherms Climathermprevents these systems rom degrading over time and reducesinitial installation costs.

Aquatherm-recommended Strategy

Per orm an energy study comparing the li etime energy costso the baseline heating and cooling system as outlined inASHRAE 90.1 2007 with a hydronic heating and cooling system,based on the buildings design speci cations. When possible,

engineer the system to operate using low temperature param-eters. Calculate the amount o energy that can be saved byswitching to hydronics. Add this into your total simulated savings.

Install the hydronic system using Aquatherms Climathermpipes to ensure that the per ormance o the system does notdegrade over time.

Major Strategy: Hydronic Heating and CoolingEA Credit 2: On-site Renewable Energy 3

17 Points

Intent To encourage and recognize increasing levels o on-site renew-able energy sel -supply to reduce environmental and economicimpacts associated with ossil uel energy use.

Requirements

Use on-site renewable energy systems to o set building energycosts. Calculate project per ormance by expressing the energyproduced by the renewable systems as a percentage o thebuildings annual energy cost and use the table below to deter-

mine the number o points achieved.

Use the building annual energy cost calculated in EA Credit1: Optimize Energy Per ormance or the U.S. Department o Energys Commercial Buildings Energy Consumption Surveydatabase to determine the estimated electricity use.

The minimum renewable energy percentage or each pointthreshold is as ollows:

13% 7

Relevance o Aquatherm to the LEED Credit The most convenient sources o on-site renewable energyinclude solar and geothermal energy. Most sites have the abilityto take advantage o these sources in some way.

Hydronic heating and cooling systems can be designed tounction at low temperatures, making them ideal or integra-

tion with solar energy collectors and geothermal systems.Climatherm can be directly buried in the ground and has a UV-protected upgrade option.

Aquatherm-recommended StrategyBased on local conditions, design the hydronic heating andcooling system to take advantage o available solar andgeothermal energy. Use solar heating panels on the roo or inopen spaces to help reduce the heating load. Use ground sourceenergy to reduce both heating and cooling demands.

Calculate the buildings projected energy use with the renew-able sources and compare it to the projections in EA Credit1. Use the di erence to nd the percentage o energy beinggenerated by these renewable resources. Apply this savingstowards the total renewable energy points.

Major Strategy: Hydronic Heating and CoolingEA Credit 4: Enhanced Re rigerant Management 4

2 Points

Intent To reduce ozone depletion and support early compliance withthe Montreal Protocol while minimizing direct contributions toclimate change.

Requirements

OPTION 1

Do not use re rigerants.

OR

OPTION 2

Select re rigerants and heating, ventilation, air conditioningand re rigeration (HVAC&R) equipment that minimize or elimi-nate the emission o compounds that contribute to ozonedepletion and climate change. The base building HVAC&Requipment must comply with the ollowing ormula, which setsa maximum threshold or the combined contributions to ozonedepletion and global warming potential:

Calculation defnitions or LCGWP + LCODP x 10 5 100

LCODP = [ODPr x (Lr x Li e +Mr) x Rc]/Li e

LCGWP = [GWPr x (Lr x Li e +Mr) x Rc]/Li e

LCODP: Li ecycle Ozone Depletion Potential (lb CFC 11/Ton-Year)

LCGWP: Li ecycle Direct Global Warming Potential (lb CO 2 /Ton-Year)

GWPr: Global Warming Potential o Re rigerant (0 to 12,000 lb CO 2 /lbr)

ODPr: Ozone Depletion Potential o Re rigerant (0 to 0.2 lb CFC 11/lbr)

Lr: Re rigerant Leakage Rate (0.5% to 2.0%; de ault o 2% un-less otherwise demonstrated)

Mr: End-o -li e Re rigerant Loss (2% to 10%; de ault o 10%unless otherwise demonstrated)

Rc: Re rigerant Charge (0.5 to 5.0 lbs o re rigerant per ton o gross ARI rated cooling capacity)

Li e: Equipment Li e (10 years; de ault based on equipmenttype, unless otherwise demonstrated)

For multiple types o equipment, a weighted average o all basebuilding HVAC&R equipment must be calculated using the

ollowing ormula:

Calculation defnitions or

[ (LCGWP + LCODP x 105) x Qunit ] / Qtotal 100Qunit = Gross ARI rated cooling capacity o an individual HVAC or re rigeration unit (Tons)

Qtotal = Total gross ARI rated cooling capacity o all HVA C orre rigeration

Small HVAC units (de ned as containing less than 0.5 poundso re rigerant) and other equipment, such as standard re rigera-tors, small water coolers and any other cooling equipment thatcontains less than 0.5 pounds o re rigerant, are not consideredpart o the base building system and are not subject to the re-quirements o this credit.

Do not operate or install re suppression systems that containozone-depleting substances such as CFCs, hydrochlorofuoro-carbons (HCFCs) or halons.


By combining geothermal energy sources with low tempera-ture operating parameters, hydronic cooling systems canbe engineered to not require any re rigerants or the coolingsystem. Climatherm is per ectly suited to cold-water pipesbecause its natural insulation makes the system more e cientand prevents water condensation in most cases.


When possible, use ground-source energy to completelysupply the cooling or the building. I necessary, supplementthe ground-source energy with HVAC equipment that has a to-tal LCGWP and LCODP o 0.001 or less, per LEED guide lines.

Major Strategy: Hydronic Heating and CoolingIEQ Credit 1: Outdoor Air Delivery Monitoring 5

1 Point

Intent To provide capacity or ventilation system monitoring to helppromote occupant com ort and well-being.

Requirements

Install permanent monitoring systems to ensure thatventilation systems maintain design minimum requirements.Con gure all monitoring equipment to generate an alarmwhen airfow values or carbon dioxide (CO2) levels vary by 10%or more rom the design values via either a building automa-

tion system alarm to the building operator or a visual or audiblealert to the building occupants

AND

CASE 1. Mechanically Ventilated Spaces

Monitor CO 2 concentrations within all densely occupied spaces(those with a design occupant density o 25 people or more per1,000 square eet). CO 2 monitors must be between 3 and 6 eetabove the foor.

Provide a direct outdoor airfow measurement device capableo measuring the minimum outdoor air intake fow with anaccuracy o plus or minus 15% o the design minimum out-door air rate, as de ned by ASHRAE Standard 62.1-2007 (witherrata but without addenda 1) or mechanical ventilationsystems where 20% or more o the design supply airfow servesnondensely occupied spaces.

CASE 2. Naturally Ventilated Spaces

Monitor CO 2 concentrations within all naturally ventilated spac-es. CO2 monitors must be between 3 and 6 eet above the foor.One CO 2 sensor may be used to monitor multiple nondenselyoccupied spaces i the natural ventilation design uses passivestack(s) or other means to induce airfow through those spacesequally and simultaneously without intervention by buildingoccupants. 2

Relevance o Aquatherm to the LEED CreditEach through-the-wall air conditioning unit creates an outdoorair delivery point in a building. The more points o delivery inthe building, the more di cult they become to monitor.

By upgrading rom a PTAC system to a centralized hydronicheating and cooling system, designers can eliminate dozens o holes in the side o a building, making it much easier to monitorthe buildings intake points.


Minimize the number o delivery points by designing the buildingwith a hydronic heating and cooling system rather than onethat relies on orced air. Install the recommended monitors atthe remaining delivery points.

Major Strategy: Hydronic Heating and CoolingIEQ Credit 2: Increased Ventilation 6

1 Point

Intent To provide additional outdoor air ventilation to improve indoorair quality (IAQ) and promote occupant com ort, well-being andproductivity.

Requirements

CASE 1. Mechanically Ventilated Spaces

Increase breathing zone outdoor air ventilation rates to all occu-pied spaces by at least 30% above the minimum rates required

by ASHRAE Standard 62.1-2007 (with errata but without adden-da 1) as determined by IEQ Prerequisite 1: Minimum Indoor AirQuality Per ormance.

CASE 2. Naturally Ventilated Spaces

Design natural ventilation systems or occupied spaces tomeet the recommendations set orth in the Carbon Trust GoodPractice Guide 237 (1998). Determine that natural ventilation isan e ective strategy or the project by ollowing the fow dia-gram process shown in Figure 1.18 o the Chartered Institutiono Building Services Engineers (CIBSE) Applications Manual 10:2005, Natural Ventilation in Non-domestic Buildings.

AND

OPTION 1

Use diagrams and calculations to show that the design o thenatural ventilation systems meets the recommendations set

orth in the CIBSE Applications Manual 10: 2005, Natural Venti-lation in Non-domestic Buildings.

OR

OPTION 2

Use a macroscopic, multizone, analytic model to predict thatroom-by-room airfows will e ectively naturally ventilate,de ned as providing the minimum ventilation rates requiredby ASHRAE 62.1-2007 Chapter 6 (with errata but withoutaddenda), or at least 90% o occupied spaces.

Relevance o Aquatherm to the LEED CreditA hydronic system can be engineered independently o theventilation system, providing greater design fexibility. This alsoallows the air circulation to operate independently o the heat-ing or cooling demand.


Use a hydronic system or heating and cooling rather than aorced air system. Design the ventilation system to ul ll the

requirements o the LEED credit independently o the heating

and cooling system.

Major Strategy: Hydronic Heating and CoolingIEQ Credit 6.2: Controllability o SystemsThermal Com ort 7

1 Point

Intent To provide a high level o thermal com ort system control 1 byindividual occupants or groups in multi-occupant spaces (e.g.,classrooms or con erence areas) and promote their productivity,com ort and well-being.

Requirements

Provide individual com ort controls or 50% (minimum) o thebuilding occupants to enable adjustments to meet individualneeds and pre erences. Operable windows may be used in lieu

o controls or occupants located 20 eet inside and 10 eet toeither side o the operable part o a window. The areas o oper-able window must meet the requirements o ASHRAE Standard62.1-2007 paragraph 5.1 Natural Ventilation (with errata butwithout addenda 2).

Provide com ort system controls or all shared multi-occupantspaces to enable adjustments that meet group needs and pre -erences.

Conditions or thermal com ort are described in ASHRAE Stan-dard 55-2004 (with errata but without addenda 2) and includethe primary actors o air temperature, radiant temperature, airspeed and humidity.

Relevance o Aquatherm to the LEED CreditUsing zone controls and mixing valves, hydronic systems can bedesigned to ocus heating and cooling into very speci c areas,giving each room its own climate control. Using radiant panels,sections o the same room can even be divided into individualclimate zones, e ectively allowing each planned occupant o the building to have direct control over their surroundings.


Based on the buildings intended use, design the heating and

cooling system to provide individual com ort or 50% or moreo the buildings occupants. Use a hydronic system with more,smaller an coil units to provide zone speci c conditioning inlarge, open rooms.

1 For the purposes o this credit, com ort system control is de ned as control over at least 1 o the ollowing primary actors in the occupants vicinity: air temperature, radianttemperature, air speed and humidity.

1 Point

Intent

To provide a com ortable thermal environment that promotesoccupant productivity and well-being.

Requirements

Design heating, ventilating and air conditioning (HVAC)systems and the building envelope to meet the requirementso ASHRAE Standard 55-2004, Thermal Com ort Conditions orHuman Occupancy (with errata but without addenda 1).Demonstrate design compliance in accordance with the Sec-tion 6.1.1 documentation.

Relevance o Aquatherm to the LEED Credit There are many methods o providing heating and coolingto a building. The choice o which system to use depends onseveral actors, including initial cost, operating cost, com ort andper ormance.

Installing a hydronic heating and cooling system providesthermal com ort to a building without introducing exteriorpollutants, dra ts, humidity, or noise. Climatherm is particularlysuited to this application because it generates less noise thanother piping systems and is not susceptible to water hammer.


Design a hydronic heating and cooling system that meets therequirements o ASHRAE Standard 55-2004 using AquathermsClimatherm piping or added occupant com ort.

Major Strategy:Installing Rainwater and Recycled Water Systems6 - 9 Points

This section ocuses on a major building strategy that coversseveral LEED credits. This strategy yields 6 - 9 points.

This strategy involves designing and installing a rainwatercollection system, a wastewater recycling system, and a non-potable distribution system on the site. The rainwater andrecycled water can be used or suitable applications wherepotable water would otherwise have been used. This reducesboth the buildings drain on the local potable water supply andits overall wastewater generation. Installing rainwater collectionand water recycling systems is in keeping with the goals o theLEED program because these systems improve the buildingsoverall sustainability and reduce its environmental impact.

Aquatherm recommends using the Lilac line wheneverpressure piping is needed, such as irrigation or fushing distri-bution. Rainwater is highly oxygenated and usually containssediment, which is extremely corrosive to most types o pipe.But Lilac pipe is made rom high-quality polypropylene, whichis resistant to corrosion and chemical breakdown. It is sa e todirect-bury and wont leach into the water, protecting the localwater table rom contamination.

When designing or sustainability, it is important to installsystems that last as long as possible. Replacing systems that

have ailed prematurely is a waste o energy and resources. TheLilac systems polypropylene composition and usion connec-tions give it an industry-leading 50-year service li e in rainwaterand recycled water applications.

Most importantly, when using a non-potable line inside thebuilding, it is required that the line be speci cally colored toprevent accidental crossover with the potable system. Lilacpiping is distinctly colored purple or this express purpose.

In summary, adding systems to collect rainwater, recyclewastewater, and distribute non-potable water helps improve abuildings per ormance and earn LEED credits. Aquatherms

Lilac pipes are the best choice or the pressurized sections o those systems.

Major Strategy: Rainwater and Recycled Water SystemsSS Credit 6.1: Stormwater DesignQuantity Control 9

1 Point

Intent To limit disruption o natural hydrology by reducing imperviouscover, increasing on-site in ltration, reducing or eliminatingpollution rom stormwater runo and eliminating contaminants.

Requirements

CASE 1. Sites with Existing Imperviousness 50% or Less

OPTION 1

Implement a stormwater management plan that preventsthe postdevelopment peak discharge rate and quantity romexceeding the predevelopment peak discharge rate and quan-tity or the 1- and 2-year 24-hour design storms.

OR

OPTION 2

Implement a stormwater management plan that protectsreceiving stream channels rom excessive erosion. The storm-water management plan must include stream channel protec-tion and quantity control strategies.

CASE 2. Sites with Existing Imperviousness Greater Than 50%

Implement a stormwater management plan that results ina 25% decrease in the volume o stormwater runo rom the2-year 24-hour design storm.

Relevance o Aquatherm to the LEED CreditOne o the most e cient methods o reducing rainwater run-o is collecting and reusing the stormwater. In order to make e ec-tive use o the stormwater, the project should have a reclaimedwater system. This system can take the stored stormwater anddistribute it throughout the building and grounds or variousnon-potable applications. Aquatherms Lilac pipe is designedspeci cally or this type o distribution.


Install in ltration points on the site that allow the rainwaterto be collected. Install a rainwater distribution system usingAquatherms Lilac pipe, which is colored purple to preventcrossover into the potable lines. Use the rainwater or vari-ous tertiary-level applications, such as irrigation, fushing, andcustodial applications.

Intent To limit disruption and pollution o natural water fows bymanaging stormwater runo .

Requirements

Implement a stormwater management plan that reducesimpervious cover, promotes in ltration and captures and treatsthe stormwater runo rom 90% o the average annual rain all1using acceptable best management practices (BMPs).

BMPs used to treat runo must be capable o removing 80%o the average annual postdevelopment total suspendedsolids (TSS) load based on existing monitoring reports. BMPs areconsidered to meet these criteria i :

They are designed in accordance with standards andspeci cations rom a state or local program that hasadopted these per ormance standards,

OR

There exists in eld per ormance monitoring datademonstrating compliance with the criteria. Datamust con orm to accepted protocol (e.g., TechnologyAcceptance Reciprocity Partnership [TARP], Washing-ton State Department o Ecology) or BMP monitoring.

Relevance o Aquatherm to the LEED CreditBe ore being used in tertiary applications, it is best to treat thecollected stormwater to remove sediment. I mechanical treat-ments are used, Aquatherms Lilac pipe is an ideal choice ortransporting the untreated water rom the collection point tothe treatment equipment. Lilac pipe is abrasion and corrosionresistant, and chemically inert, so it will not be damaged by thesediment in the water.


Install a rainwater collection system with as many in ltrationpoints as possible, so as to reduce pollutant loadings. Whereneeded, channel water rom the impervious area into thecollection point. Treat the rainwater as needed and use it orsuitable applications around the building. Use any collectedsediment or landscaping purposes or dispose o it properly.

OR

PATH 2

Install landscaping that does not require permanent irrigationsystems. Temporary irrigation systems used or plant establish-ment are allowed only i removed within 1 year o installation.

Relevance o Aquatherm to the LEED CreditA reclaimed water system acts as an onsite source o non-potable water. Using this water or irrigation helps reduce thepotable water demand. By combining high-e ciency rainwaterand recycled water systems with low-demand landscaping, theneed or potable water in irrigation can be eliminated.

Aquatherms Lilac system is colored purple to distinguish itrom potable waters. The pipe itsel can be directly buried and

is resistant to reezing, crushing, and leaking, making it ideal oran irrigation system.

2 Points (w/ LEED Credit ID Exemplary Per ormance (1 point) Total: 3 Points)

Intent To reduce wastewater generation and potable water demandwhile increasing the local aqui er recharge.

Requirements

OPTION 1

Reduce potable water use or building sewage conveyance by50% through the use o water-conserving xtures (e.g., waterclosets, urinals) or nonpotable water (e.g., captured rainwater,

recycled graywater, on-site or municipally treated wastewater).

OR

OPTION 2

Treat 50% o wastewater on-site to tertiary standards. Treatedwater must be in ltrated or used on-site.

Relevance o Aquatherm to the LEED Credit Treating the buildings wastewater on-site helps reduce itstotal wastewater generation and provides non-potable water ortertiary applications. Aquatherms Lilac pipe utilizes all theadvantages o a polypropylene usion system and is uniquelycolored in order to avoid cross contamination between thepotable and non-potable lines.


Set up a reclaimed water system that captures at least 50%

the buildings wastewater and treats it to a tertiary level. Usethis water or fushing urinals and toilets, reducing the amounto water used or sewer conveyance by at least 50%. Accom-plishing both o these options can be counted as doubling therequirement, which can be applied to an ID credit or ExemplaryPer ormance (see page 16).

Innovation in Design Credits

There are many ways to help improve the environment per ormance o a building. Not all o these can be addressed in a singledocument, and so the USGBC has included LEED credits or design innovation and exemplary per ormance. These credits areawarded or establishing and meeting an acceptable criteria that improves the buildings overall environmental per ormance in asigni cant and measurable way.

Aquatherms piping systems are some o the most advanced and environmentally responsible pressure piping systems in the world.Using them to replace the current industry-standard materials o ers a wide range o per ormance, longevity, and environmentalbene ts.

The primary bene t o Aquatherms piping systems is that they have the smallest carbon ootprint o any piping system.Polypropylene generates a raction o the pollution require to create metal systems, and it does not contain any o the hazardousmaterials ound in other plastics.

This section shows how to treat upgrading to Aquatherm as an innovation in design by quanti ying the overall increase inenvironmental per ormance.

Aquatherm-recommended StrategyIn 2007, the LEED Technical and Scienti c Advisory Commit-tee PVC Task Group published its conclusions on an extensivematerial analysis regarding the risks and bene ts o PVC as abuilding material. Their conclusions included a recommenda-tion to establish credits incentivizing the substitution o prob-lematic materials with others that are demonstrably better withregard to environmental and human health impacts over theirli e cycles.14

Following this assessment, it is recommended to seek creditsor using materials that generate signi cantly lower emissions

to manu acture and install, thus reducing the impact on envi-ronmental and human health.

It is also recommended to seek credits or using a material thatavoids use o problematic chemicals without introducing otherproblematic chemicals, thus protecting the environment andthe humans in and around the site.

Follow the subsequent guidelines to replace problematic

piping systems with systems that ul ll the TSVCs recommen-dation. Apply or LEED ID Credits based on those guidelines.

Credit Contributions

With very ew exceptions, simply changing a building material is not going to satis y LEED credit requirements. The LEED program isocused on innovative engineering and responsible construction management and the points are earned in those elds.

There are several credits or which upgrading to Aquatherm is not a signi cant enough improvement to earn a ull point. However, itcan still contribute to the overall credit. We re er to these as credit contributions and they are addressed in the ollowing section.

Credit contributions are important to an overall LEED rating. For example, switching to Aquatherm can signi cantly reduceon-site pollutants. This helps lower the number o other materials that need to be addressed in order to receive the point. And usingAquatherm in place o the standard materials actually improves per ormance rather than diminishing it.

This section helps identi y the credits or which Aquatherms contribution needs to be tracked and added into the overallrequirement rating.

The pumps used to transport water and other fuids aroundthe site play a signi cant role in the total electricity consump-tion o the building. There are a number o ASHRAE guidelinesregarding the e ciency o pumps and motors, but there is little

consideration or the riction actor within the piping system.Friction in the piping system results in lost pumping energy, aswell as reduced per ormance and a shortened li e-cycle or thepumps and motors.

Aquatherms polypropylene piping systems have a lowerriction actor than copper or steel piping systems. Replacing a

standard metal piping system with an equivalent polypropyl-ene piping system can reduce the amount o pumping energylost in the system, improving overall e ciency.

By reducing the amount o energy lost to riction in a pipingsystem, the amount o electricity used by the pumps and mo-tors can be signi cantly reduced. In the case o a steel hydronicsystem, 50% di erence in the pipe riction actor can yield a30% savings in annual energy use o the pumping system. Thetotal percentage o the buildings energy use is dependent onthe size and application o the system, as well as the other ener-gy-consuming systems on the site.

Furthermore, the riction actor o metal systems, particularlysteel, tends to increase over time, as corrosion and scaling

begin to restrict water-fow. Aquatherm piping systems are notsubject to corrosion or scaling and will continue to per orm atthe same level throughout the li e o the system.


Calculate the estimated annual energy use o the pumps andmotors, based on an industry standard system. Implement apolypropylene piping system with a lower pipe riction actorand calculate the di erence in energy consumption. Add thistotal to the buildings proposed per ormance rating.

Credit ContributionsIEQ Credit 3.1: Construction Indoor Air Quality Management PlanDuring Construction 18 1 Point

Intent To reduce indoor air quality (IAQ) problems resulting romconstruction or renovation and promote the com ort and well-being o construction workers and building occupants.

Requirements

Develop and implement an IAQ management plan or theconstruction and preoccupancy phases o the building as ollows:

During construction, meet or exceed the recommend-

ed control measures o the Sheet Metal and Air Con-ditioning National Contractors Association (SMACNA)IAQ Guidelines For Occupied Buildings Under Con-struction, 2nd Edition 2007, ANSI/SMACNA 008-2008(Chapter 3).Protect stored on-site and installed absorptive materi-als rom moisture damage.I permanently installed air handlers are used duringconstruction, ltration media with a minimum e cien-cy reporting value (MERV) o 8 must be used at eachreturn air grille, as determined by ASHRAE Standard52.2-1999 (with errata but without addenda 1). Replaceall ltration media immediately prior to occupancy.

Relevance o Aquatherm to the LEED CreditDuring construction, the umes generated by welding, solder-ing, and gluing a piping system together can contaminate theair inside the site, as well as permeate absorbent materials suchas paints, carpets, insulation, etc.

The use o heat- usion connections eliminate the umesproduced by soldering, welding, and gluing the piping systemstogether. This helps minimize the number o pollutant sourcesin the building, as well as reducing the risk o contamination orabsorptive materials. This can be included into the IAQ Manage-ment Plan, improving the overall air quality while reducing the

amount o resources and planning needed to do so.


Implement a polypropylene piping system with heat- usionconnections in place o a standard piping system, removingsoldering, welding, and gluing as a source o indoor pollutantsand contaminants. Take this into consideration while generat-ing the IAQ Management Plan.

Drastically reduce or eliminate VOCs caused by PVC welding,CPVC welding, plastic cement welding, and adhesive primers

or plastic by implementing a piping system with heat- usionconnections. Replace these systems with equivalent usible

polypropylene systems, such as Aquatherm Greenpipe andClimatherm, removing these VOCs rom the site entirely, as wellas the need to track and document them.


Many plastic piping systems are joined using glues or chemi-cal welding. These processes o ten generate a large volume o dangerous VOCs on a jobsite. VOCs are dangerous to humanhealth as well as the environment and atmosphere.

PVC welding, CPVC welding, plastic cement and adhesive prim-ers can account or up to 1800 g/L o VOCs on the site, 22%o the total allowable VOCs on a job site. The majority o theseprocesses are used in piping applications. The unction o theseapplications can o ten be handled by a di erent piping materi-al, making it easy to completely remove these sources o indooremissions rom the site.

Aquatherm piping systems are VOC ree, and are joined usinga sa e and clean heat- usion process. This makes them an idealcandidate to replace glued and chemically welded systems inmost cases.
