ISBN: Rideshare Location Minimum trip count: 72 weekday and 40 Weekend trips 2. Ensure that any functional entry is within ½ mile walking distance of either: a. Bus Rapid Transit stop b. Light or Heavy Rail Station or c. This credit requires that adequate bicycle storage be provided for short-term and long-term visitors as well as a connection to a bicycle network. A network consists of off-street bicycle paths or on-street bicycle lanes 2. The bicycle network must be within 3 miles of one of the following: a. A school or employment center If residential project c. Bus Rapid Transit, Light or Heavy Rail Station or a Commuter rail or ferry terminals 3. Provide Showers for occupants in commercial spaces Reduced Parking Footprint — LTc7 The US has twice as many parking spots as people!

Most of these spaces are impervious and above ground. The intent of this credit is to reduce automobile dependance and reduce impervious pavement which is detrimental to our environment due to rainwater runoff and contribution to the heat island effect To be discussed in Sustainable Sites. This credit has 3 requierments: 1. Do not exceed local zoning code requirement 2. Reduce Parking capacity from Baseline ITE Handbook Standard a. Parking closest to the entrance Green Vehicles — LTc8 Gasoline powered automobiles are not the only option for car ownership as hybrids, electric vehicles and alternatively fueled vehicles are gaining popularity. There are two requirements for this credit: 1. Provide Electric Vehicle Charging Stations - OR - 2. This chapter will discuss the Sustainable Sites category and the strategies to achieve it. Sustainable Sites interacts with the Location and Transportation credit category as SS also depends on the chosen location but focuses on the existing site conditions rather than its surroundings.

Developers are encourages to design and construct with the natural elements provided by the site as opposed to disturbing it and fighting nature. Sustainable Site Design A sustainable site design considers the whole development footprint including landscaping and hardscapes. Construction Activity Pollution Prevention — SSp1 It is essential to minimize environmental impacts during construction process. Construction activities result in:  The loss of the topsoil  Loss of nutrients, soil compaction and decreased biodiversity  Water pollution due to water runoff which carries pollutants and sediments to receiving water  Airborne dust which causes environmental and health issues  The degradation of water bodies and aquatic habitats -The project team must develop and implement an Erosion and Sedimentation Control Plan ESC to reduce construction pollution; the ESC plan must comply with the EPA General Construction Permit or local codes, whichever is more stringent.

This credit requires that the natural conditions be evaluated and include: 1. Topography - Contour mapping and slope stability risks. Hydrology - Flood hazard areas, delineated wetlands and other bodies of water 3. Climate - Solar exposure, heat island effect potential, sun angles, winds, precipitation and temperature 4. Vegetation - Plant types, tree mapping, threatened or endangered species, and unique habitat 5. Soils - prime farmland, healthy soils, previous development, disturbed soils 6. Human use - Views, transportation infrastructure, adjacent properties and materials effects 7.

Human health effects Proximity of vulnerable populations, and proximity to sources of air pollution Site Development: Protect and Restore Habitat — SSc2 The intent of this credit is to conserve the existing natural features and attempt to restore what was originally on the site. This credit has two options: 1. Open space provides a habitat for vegetation and wildlife; while reducing the urban heat island effect, increasing storm water infiltration and connecting humans to the outdoors. A compact high- rise building with the same square footage as a low-rise building reduces the building footprint and minimizes the disturbance of the existing ecosystem.

This credit has requirements based on open space set aside: 1. A Note on vegetative roofs for SSc2 and SSc3: Extensive Green Roof — vegetative roof not designed for human access and minimal maintenance Intensive Green Roof — vegetative roof with a variety of plants and human uses. Native and adaptive plants are encouraged Projects that achieve a density of 1. New developments reduce the natural permeability of sites and increase rain water runoff. Increased runoff rates can result in erosion and sedimentation of waterways. The water quality is reduced due to pollutants carried by runoff water and can be harmful to aquatic life in receiving waters. It is useful to note the amount of tax dollars and energy required to pump and treat storm water that runs off into our municipal water systems. A storm Water Management plan SWP often includes strategies to collect and reuse storm water to reduce the water runoff from the site.

Strategies to manage storm water addresses both water quality and quantity. LEED encourages practices that reduce storm water runoff and protect the quality of both surface and ground water. This accomplished by reducing the impervious surface area and adding structural or nonstructural features that retain water onsite to allow infiltration and reuse. maintain vegetative swales, rain gardens and minimize impervious cover. Heat Island Reduction — SSc5 Figure 27 A heat island is defined as the thermal differences between developed and undeveloped areas. Urban areas experience higher temperatures as compared to their surrounding rural counterparts due to: - The abundance of dark hardscapes such as asphalt and concrete which absorb and store heat during day and release it at night.

LEED refers to Heat island as the rise in temperatures from 2 to 10 degrees in urban areas higher than surrounding rural areas, addressing both roof and non-roof components in two different credits under the sustainable sites category. Cool pavements and cool roofs are terms referring to materials with lower emissivity and higher albedo and subsequently higher Solar Reflectance Index SRI. Solar reflectance or albedo is the fraction of the solar energy reflected by a surface defined as a number between 0 and 1. The higher the number the better the roof reflects energy. Solar reflectance index SRI is the measure of the constructed surface ability to reject solar heat, a combined value of reflectivity and emissivity. It is defined so that standard black is zero reflectance 0.

This is used for roof surfaces. Solar Reflectance SR — the fraction of solar energy that is reflected by a surface on a scale of 0 to 1. Black paint is 0 and white paint is 1. This is used for non-roof surfaces Strategies for reducing heat island effect: - Non roof Hardscapes: Decrease areas of impervious hardscape and use higher solar reflectance materials. Use cool pavements with three year aged SR of. Light pollution disrupts ecosystems, affects health and reduces night sky observation. LEED promotes well designed lighting systems that reduce light pollution. LZ0 — No Ambient Lighting 2. LZ1 - Dark park and rural settings 3. LZ2 - Low residential areas and neighborhood business districts 4. LZ4 - High major city centers and entertainment districts There are two options to achieve this credit and both deal with restricting uplight and light trespass off the site.

Backlight-Uplight-Glare BUG Method Based on the Illuminating Engineering Society IES TM standard — do not exceed luminaire ratings per zone 2. Alternatively share a space owned by another organization such as an offsite gymnasium. Ensure that there is direct pedestrian access and toilet access afterhours. Core and Shell Only - Tenant Design and Construction Guidelines— SSc7 The project team must create an easily understandable document to ensure tenants understand the sustainable features and utilize them in case they fit it out in the future. These credits deal with mimicking the outdoor environment indoors places of respite or creating an accessible outdoor space such as courtyards or terraces Direct Exterior Access. Over billion gallons of water are used each day in U. According to the United Nations Environment Program, if our present patterns continue, two out of every three people will live in water-stressed conditions by the year and 1.

every year because of inefficient toilets. LEED encourages the use of strategies and technologies that reduce the amount of potable water consumed in buildings, while meeting the needs of the systems and occupants. Many strategies are no cost or provide a rapid payback. Water use reduction can reduce the burden on wastewater treatment facilities. This credit category focusses on efficiency first as the prerequisites attempt to reduce waste, and credits look at the integration of alternative sources of water such as graywater. Water Efficiency versus Conservation- Conservation focusses on policies and activities to manage the use of water whilst efficiency is the reduction of water needed for a specific purpose. Conservation is defined as trying to reduce water use entirely and efficiency aims to reduce waste by using less for the same task Full Time Equivalents FTEs - the FTE of a project must be consistent across all credits. FTE is a regular building occupant who spends 40 hours per week in the project building.

Part time or overtime occupants have FTE values based on their hours inside the building per week divided by FTEs are based on an 8 hour occupancy period per day. An 8 hour 5 days a week full time occupant has an FTE value of 1. FTEs are needed to calculate the baseline, and design case water usage of a building. FTE identifies the total number of building occupants according to their occupany types:  Full time staff  Part time staff  Peak Transients students, volunteers, visitors, customers, etc. Graywater or greywater - domestic wastewater from bathroom and laundry sinks, tubs, showers and washers.

The Uniform Plumbing Code UPC defines gray water as untreated household wastewater that has not come in contact with toilet waste; the International Plumbing Code IPC defines graywater as wastewater discharged from lavatories, bathtubs, showers, clothes washers and laundry sinks. Most states will not allow kitchen sinks or dishwashers to be included with graywater. Most jurisdictions consider water from kitchen sinks and dishwashers to be blackwater and it cannot be reused Process water- water used for industrial processes and building systems such as boilers, cooling towers and chillers Stormwater runoff- runoff water resulting from precipitation that flows over surfaces, and conventionally into storm sewers or waterways WaterSense- is an EPA sponsored program that promotes and certifies water-efficient products, programs, and practices.

WaterSense helps consumers identify water efficient products, and programs that meet WaterSense water efficiency and performance criteria. Watersense fixtures must use some amount of water IE. Waterless urinals do not comply Gallons per flush gpf - the flow rate measurement unit for flush fixtures such as water closets and urinals. Gallons per minute gpm - the flow rate measurement unit for flow fixtures such as faucets,showerheads, aerators, sprinkler heads Waterless urinals- works completely without water or flush valves by passing urine through a liquid seal.

There are two varieties of waterless urinal: cartridge based and non cartridge based units. Water use reduction calculations depend on the number of FTEs, not the number of fixtures, and the default ratio between male and female occupants is Calculations are used to compare actual efficient specified fixtures versus the baseline conventional flush and flow fixtures. All newly installed toilets, urinals, private lavatory faucets, and showerheads that are eligible for labeling must be WaterSense labeled or a local equivalent for projects outside the U.

Modern water distribution systems have many components in the project and on its site which results in ample leakage opportunities. Meters are a proactive approach to locating leaks. The Building level water metering prerequisite requires that all potable water sources be metered such as public supply, on-site well and on-site potable water treatment systems. If there are multiple potable sources additional meters may be required. This meter must collect data for total water use in the building and on its associated grounds as well as commit to sharing annual summaries with the USGBC for 5 years. The water metering credit requires two or more permanently installed system-level water meters for the following subsystems: 1. Process water is the water used in building equipment such as cooling towers. However, this water evaporates and unwanted dissolved solids build up and results in removal of this unwanted concentrated water blowdown to prevent inefficient scaling in the equipment.

Makeup water must then be added to compensate for blowdown and evaporation. This credit attempts to maximize the amount of times the water can cycle through the system before being removed by blowdown. This credit requires a one-time potable water analysis to determine the concentration of at least five dissolved solids and ensure maximums are not surpassed. Department of Energy generating electricity from fossil fuel such as natural gas, oil and coal negatively affects the environment throughout its life cycle. The damage begins with extraction and transportation, followed by refining and distribution and concluding with consumption burning. Buildings in the U. The Energy and Atmosphere category has the most points available within the LEED rating systems and promotes efficiently designed buildings and sourcing energy from renewables.

This category addresses both energy and refrigerant usage in the building. Comissioning ensures that the building owner gets the performance out of the efficient systems. Fundamental commissioning of building energy systems is required in a prerequisite while enhanced commissioning is addressed in another credit. Optimized energy performance and higher percentages of energy efficiency are needed to earn points. The number of points depends on the percentage of energy cost savings. The energy performance of a building depends on the reduction of energy demand by the building and the efficiency of the building systems installed as compared to a baseline. Energy models include all energy end uses including lighting, HVAC and domestic hot water and process energy which includes office equipment, computers, elevators, escalators, kitchen cooking and refrigeration, laundry washing and drying machines, lighting that is exempt from the lighting power allowance. Various energy modeling software include EE4, eQuest, IES and EnergyPlus.

Energy simulation allows the project team to make better decisions based on the results of the simulation analysis. The model takes into account all mechanical and passive building features including its location and orientation. The final design reports are then submitted via LEED online to show percentage improvements. The target can then be measured against a variety of design strategies. The program outputs how much energy the average building in the area by type and zip code consumes and how much a high-performance building in the area would consume.

Target Finder is mandatory compliance for the LEED for Schools prerequisite. Energy Star Portfolio Manager: is an interactive energy management tool that allows tracking and assessing energy and water consumption as well as GhG emissions across an entire portfolio of buildings in a secure online environment. Strategies for reducing energy demand:  Energy goals: set energy saving targets early on in the project and verify their achievement. Computer simulated 3D models help designers and architects predict how the building will perform before it is built and design accordingly.

Energy Efficiency Strategies implemented to reduce energy demand are the basis of increasing energy efficiency. Energy efficiency strategies:  Passive design and thermal energy storage: determine the best building orientation and massing to benefit from the passive design opportunities such as day lighting, natural ventilation and passive heating and cooling from the sun and the wind. Figure 41  High performance building envelope: installing high- performance glazing systems and efficiently insulating the building envelope will prevent heating and cooling losses. Metering can identify opportunities for additional energy savings on a building of system level scale. They must be:  Record at hour intervals  Record Demand and Consumption  Transmit data to Remote Location Building Automation System BAS Software which is used to control as well as monitor building energy demand and consumption. The automation system is used to maintain occupant comfort while meeting energy consumption goals and identifying mechanical, electrical and plumbing system woes.

The most common example of a CFC is called Freon. The Montreal Protocol bans the production of chlorofluorocarbons CFCs and establishes a phase out date for the use of hydrochlorofluoro-carbons HCFCs in CFCs and HCFCs are categorized as ozone depleting substances because of their high Ozone Depletion Potential ODP. The dilemma when selecting refrigerants is that refrigerants with low ODP tend to have high Global Warming Potential GWP such as Hydroflourocarbons HFC so trade- offs among efficiency, ODP and GWP must be considered when you Figure 43 choose the refrigerant equipment. This is due to the requirement of peaker plants at peak periods of consumption which are expensive to operate and produce many harmful emissions. A demand response program enables the energy provider utility company to cut energy from demand response participants during the peak. The utility automatically sends a message and avoids the necessity of peaker plants. Strategies to adapt to a demand response event include dimming lights, cutting the chiller, reducing ventilation and minimizing leakage through doors and operable windows.

Renewable Energy Production — EAc5 Energy that is naturally replenished and generated from natural resources is called renewable energy. This energy is more sustainable and environmentally beneficial than fossil fuels because there is not a finite amount of it. LEED distinguishes between renewable energy produced onsite and purchased offsite power from renewable sources. This credit looks at on-site renewable energy. The percentage of the green power purchased is based on the quantity of energy consumption, not energy costs. Strategies to achieve this credit are as follows:  This credit is based on the quantity of energy consumped  Purchase power from green-e certified provider on closed or open electricity market to reduce Scope 1 emissions from electricity  Purchase renewable energy certificates RECs or tradable renewable certificates TRCs which represent the 1 MWh of electricity was generated from a renewable source.

Figure 47  The qualified resources must have come online since January 1, for a minimum of 5 years. Boiler — mitigated by carbon offsets Scope 2 emissions — Indirect emissions — greenhouse gas IE. Purchased electricity - mitigated by green power or RECs Green-e is a certification program for renewable energy. Renewable Energy Certificates, or Tradable Renewable Certificates TRCs , represent electricity produced from renewable energy sources sold separately from commodity. One REC represents 1 megawatt-hour MWh of electricity was generated from an eligible renewable energy resource. If there is not a green-e certified power supplier within feasible proximity to your project, an REC essentially purchases renewable power for a building that would otherwise be using standard electricity.

Material selection and material disposal are the two main issues addressed in this credit category. The Materials and Resources MR category focuses on the life cycle impacts of materials selected for the project, and the amount of material diverted from the landfill. LEED promotes the selection of sustainable materials and the reduction of waste produced from the construction, operation and demolition of buildings. In this chapter we will discuss types of sustainable materials and strategies to reduce waste sent to landfills. It focusses on the selection of environmentally preferable materials to reduce detrimental effects on human health and environmental effects to ensure improved worker safety and health.

Mechanical, electrical and plumbing MEP equipment are optional in most of the credit calculations. For example, including an expensive elevator would severely skew credit calculations, as points are rewarded based on cost of materials or surface area. The following are general concepts related to Materials and Resources category: Life Cycle Impacts: This includes its extraction, processing, transportation, use and disposal. LEED promotes reusing or recycling a product at the end of its life as opposed to disposing of it, known as the cradle to cradle approach.

LEED also wants to serve as a market mover and ensure all products go through and LCA. Purchasing Policies: LEED encourages the use of sustainable materials through this category. It determines the types of materials that should be considered for a high performance building and how to reduce the life- cycle impacts of these materials. Purchasing policies should specify where items are sourced from during construction and operation of the building. Third party certification of sustainable products is essential in materials selection. FSC certified wood. Waste reduction: The preferred waste management strategies described by the U. Environmental Protection Agency EPA are source reduction, reuse, recycling and recovery. Material reuse or recycling are forms of waste diversion from landfills or incineration works as well.

The EPA defines the following waste management strategies:  Source Reduction: the practice of designing, manufacturing, purchasing, or using materials in ways that reduce the amount of unnecessary materials in the building. Figure 49 Credit metrics and cost calculations: Each credit is based on material area, weight or cost. An easily accessible and dedicated area for the collection and storage of materials for recycling must be provided for the entire building. It can be commingled recycling or separated on site. Materials to be recycled must include, at a minimum, paper, corrugated cardboard, glass, plastics and metals.

The project must also recycle 2 of: Batteries, electronics or mercury containing lamps. The construction waste management plan must: 1. Identify and establish waste diversion goals for at least five materials structural and non-structural 2. Specify whether materials will be separated or commingled and where they will eventually be recycled or even donated 3. These calculations exclude excavated soil, land-clearing debris, and alternative daily cover ADC. In some instances where the credit cannot be met waste-to-energy systems may be included. Adapted reuse is the renovation of a space for a purpose different from the original.

There are 4 options for credit compliance: 1 — Historic Building 5 points Maintain the existing building structure, envelope, and interior non-structural elements of a historic building or contributing building in a historic district. To qualify, the building or historic district must be listed or eligible for listing in the local, state, or national register of historic places. Global warming potential greenhouse gases , in CO2e; 2. Depletion of the stratospheric ozone layer, in kg CFC; 3. Eutrophication, in kg nitrogen or kg phosphate; 5. Formation of tropospheric ozone, in kg NOx or kg ethene; and 6.

Depletion of non-renewable energy resources, in MJ. Location Valuation Factor for the following credits: The intent of this factor is to add value to locally produced materials which reduces transportation emissions and supports the local economy. To comply products must be: 1. Extracted 2. Building Product Disclosure and Optimization awards points for selected materials manufactured with transparency in regards to all ingredients. The credits strictly deal with permanent building materials and Mechanical Electrical and Plumbing which are passive such as ducts and plumbing fixture but must consistently be reported.

If furniture is to be included all products of that type must be included and kept consistent across all calculations. BPDO - Environmental Product Declarations — MRc2 Environmental Product Declarations EPDs reward teams for selecting manufactured products which have verified they have improved life cycle impacts. BPDO - Sourcing of Raw Materials — MRc3 The achievement of this credit rewards a team for selecting products that have been extracted and sourced in a responsible manner. GreenScreen v1. Cradle to Cradle Certified 3. International Alternative Compliance Path — REACH Optimization 4. Minimal chemical content 2. Testing and modeling of chemical content 3. The prerequisite looks at establishing maximum levels of mercury content in lamps and its corresponding credit requires the project to specify only low or no mercury containing lamps Another credit requires projects to minimize or eliminate the use of lead, cadmium and copper.

Minimum Indoor Air Quality Performance — EQp1 Maintaining the minimum outdoor air intake through ventilation systems is essential in improving the indoor air quality in buildings. ASHRAE Ventilation systems vary from one project to another including:  Mechanical ventilation active - ASHRAE For naturally ventilated spaces the Chartered Institution of Building Services Engineers CIBSE applications manual must be followed and an analytical model may be used to confirm that the room by room airflows meet the minimum rates required by ASHRAE Environmental Tobacco Smoke ETS Control — EQp2 Environmental tobacco smoke ETS is produced by cigarettes, pipes or cigars and is related to health risks such as lung disease, cancer and heart disease. The purpose of this prerequisite is to prevent the exposure of building occupants to ETS which is also known as second hand smoke. To achieve this prerequisite a project:  Prohibit smoking in the building and on property within 25 feet from operable windows, entries and air intakes.

Ensure each unit is compartmentalized by: o Weather-stripping all exterior and hallway doors and windows o Demonstrate a maximum leakage of 0. Projects must maintain the background noise level under 40 dBA from HVAC systems in classrooms and other core learning spaces. Enhanced Indoor Air Quality Strategies — EQc1 This credit protects the occupants from potentially hazardous particulates and chemical pollutants and is an extension of EQp1. It promotes strategies that minimize human contact with airborne chemicals and particles. Using a permanent entryway system for at least 10 feet at all regular entrances. Examples of entryway systems are installed grates and grills that capture dirt and can be cleaned underneath. Roll-out mats can be used only if they are cleaned weekly by a service organization.

Interior Cross-contamination Prevention Exhaust contamination! In mechanically ventilated buildings, use new filtration media with minimum MERV of Exterior contamination prevention — Gaussian Model to ensure maximum concentration levels are not exceeded 2. Additional source control and monitoring - alarm Low Emitting Materials — EQc2 Finishing materials with high concentrations of volatile organic compounds VOCs or formaldehyde have negative impact on IAQ. These materials are odorous, irritating and can threaten the comfort and wellbeing of occupants due to off-gassing. In LEED v4 this credit has been simplified and tests each layer of a surface even those not directly exposed to air in the interior space as defined by everything within the waterproofing membrane.

This credit has requirements for 7 different categories of materials and 2 calculation based methods to show compliance. Construction Indoor Air Quality Management — EQc3 Construction and demolition practices introduce pollutants to the building indoor environment that can have effects over the lifetime of the building. To address problems that result from construction activities an IAQ management plan should be developed and implemented during construction and before occupancy. This credit promotes best practices to ensure high indoor air quality during construction as outlined in the Sheet Metal and Air Conditioning National Contractors Association SMACNA IAQ Guidelines:  Protect absorptive materials installed or stored on site from moisture to prevent mold.

There are two options to achieve it: 1 - Flush Out by replacing all existing air with fresh outdoor air prior to occupancy. Meeting the unique needs of each occupant can be accomplished through effective design of lighting controls. Daylighting design should consider heat gain or loss that can result from daylighting strategies. Shading devices, light shelves, courtyards, atriums and window glazing are strategies of daylighting. and 3 p. Provide views to connect occupants with the outdoor environment. Multiple lines of sight 90° apart 2. Unobstructed views within 3 times the head height of vision glazing 4. There are no prerequisites for this category; projects can earn up to 6 points from the following credits:  Innovation in Design  LEED Accredited Professional Innovation in Design Projects can achieve these credits through any combination of the following paths:  Innovative performance Points  Exemplary performance Points  Pilot Credits Points Innovative Performance ID credits for innovative performance are awarded for comprehensive strategies which demonstrate quantifiable environmental benefits not specifically addressed in the LEED rating system.

The criteria on which the strategies are evaluated are:  Quantitative performance improvements of the strategy. Exemplary performance points may be earned by exceeding the requirements of the credit to next threshold or achieving double the credit requirements. LEED Accredited Professional A LEED Accredited Professional of the correct corresponding specialty IE. No matter how many LEED APs are in the project, only 1 point can be earned under this credit. This credit essentially promotes the design integration to streamline the project certification process through involving LEED APs to educate other project team members and coordinate between them. The USGBC regional councils identified different environmental regions and selected existing credits in the rating systems that should be a priority for each region according to the most crtical environmental issues.

Regional Priority credits are listed by state and determined based on a new GIS- based program. The RP credit zones in LEED v4 were created using a GIS-based program that allowed for environmental issues to be empirically mapped. This process created RP credit zones that are based on these issues rather than physical location. The project team then automatically earns 1 point in addition to any points earned in the credit. For more information about boundaries visit: www. Example In Arizona X, Y , The following credits are designated as regional priority credits  High priority site  Optimize energy performanceHeat Island Effect- Non Roof  Renewable energy production  Outdoor Water use Reduction  Building life-cycle impact reduction  Heat island reduction The project can earn an extra 4 Regional Priority points for achieving 4 of the credits mentioned above.

Figure 32 FIGURE FIGURE 95 iii Executive Summary To undertake this assignment, the TSAC impaneled an ad hoc HCFC Task Group HCFC TG , consisting of Reva Rubenstein, Ph. Chair , David Didion, D. TSAC members, Malcolm Lewis, D. Eng, P. TSAC has developed a nine-step process for preparing reports on technical issues. One of the most important elements of this process is obtaining input from the various stakeholders on an issue. Stakeholder input on a preliminary report was obtained in February Subsequently the TSAC released a revised draft final report in July that took into account the comments from stakeholders. Public comments on that revision were accepted through August Incorporating input from these later comments, this document is now the final report of this task given TSAC by the LEED Steering Committee.

The January draft of the report focused only on the refrigerants used in centrifugal water chillers. In this final phase of the work, the methodologies are expanded to the other major classes of HVAC equipment and the refrigerants used in them. Our analysis considers refrigerants used now and in the past in both centrifugal water chillers and unitary equipment: a range of chlorofluorocarbons CFCs, now banned under the Montreal Protocol , hydrochlorofluorocarbons HCFCs, scheduled for phase-out under terms of the Montreal Protocol , and hydrofluorocarbons HFCs. The ozone-depletion potential ODP of the HCFCs e.

In contrast, the HFCs e. Moreover, thermodynamic properties make the HFCs slightly less efficient refrigerants than the HCFCs given idealized equipment design, so the same amount of cooling may require more electricity and thereby causes the indirect release of more CO2 in generating that electricity. The dilemma, therefore, is that some refrigerants cause more ozone depletion than others, but the most ozone-friendly refrigerants cause more global warming. A complete analysis of the relative harms of ozone depletion and global warming is beyond the scope of this report, because the full implications of both anthropogenic effects are not known.

Version 2. It also awards credits for varying amounts of energy savings, hence rewarding the use of a more efficient refrigerant in Credit 1. The current LEED system thereby reflects the dilemma described in the previous paragraph: there is no clear win-win solution, and an architect or builder must choose between competing environmental damages. To assess the relative differences for chillers and air conditioners, we normalize ozone depletion and global warming by cooling capacity, and we compare those values with total U. emission of ozone depleting and greenhouse gases, both from direct and indirect emissions.

Our analysis suggests changes within the existing LEED credit structure, as well as in future versions of LEED, to better address these issues. The best approach is to devise a new credit structure that considers both ozone depletion and direct global warming impacts of refrigerants, as well as their indirect global warming impacts. Moreover, although the direct global warming effects of the refrigerants analyzed are smaller than the indirect effects resulting from energy generation to operate the HVAC equipment, they are not negligible and for some refrigerants they are as large as the indirect contribution.

This approach does not single out any refrigerant per se, but focuses on the impacts on the atmosphere of that refrigerant as applied in specific HVAC equipment configurations. This technically robust approach to considering refrigerant alternatives will encourage LEED users to evaluate both critical atmospheric effects. In future versions of LEED, we recommend that all emissions of ozone depleting substances and greenhouse gases—not just from refrigerants—be considered in the credit structure. This could involve separate credits for ozone depletion and global warming.

Some choices have inherent environmental tradeoffs. Technologies, materials, or practices designed to ameliorate one problem may exacerbate another. To make matters worse, the political recognition that one pollutant represents a societal threat, as compared to another, is not always timely. Such is the case with ozone depletion and global warming. While the legal protection of the ozone layer is well in place throughout most of the international community via the Montreal Protocol, the same nations lack agreement that global warming is a comparable threat. Therefore, the current regulatory program to protect stratospheric ozone was established without consideration of any impact on global warming.
