Location & Transportation Credit: Reduced Parking

Footprint

Requirements: To earn this credit project teams must accomplish both 1) not exceeding the minimum local code requirements for parking capacity and 2) providing parking capacity that is 20-40% lower than the base ratios recommended by the Parking Consultants Council, as shown in the Institute of Transportation Engineers’ Transportation Planning Handbook.

EP: Project teams may earn an additional point by providing parking capacity that is 60-80% lower than the stated base ratios (as described above) and by incorporating strategies such as parking space leasing, pedestrian travel, bicycles and public transportation usage.

Location & Transportation Credit: Green Vehicles

Requirements: A Green Vehicle is one that achieves a minimum green score of 45 on the American Council for an Energy Efficient Economy (ACEEE) annual vehicle rating guide.

To earn this point, project teams must designate 5% of all the parking spaces used by the project as “preferred parking” for green vehicles. As an alternative to 5% of all parking, green vehicles may be provided with a discounted parking rate of at least 20%... This “preferred rate” must be clearly posted at the entrance to any paid parking facility.

Project teams must also achieve one of the following two additional options: 1) Electric Vehicle Charging: Install electric vehicle supply equipment (EVSE) in 2% of all parking spaces, and designate those spaces for plug-in electric vehicles, or 2) Liquid, Gas or Battery Facilities: Install liquid or gas alternative fueling facilities or battery switching station for 2% of all parking spaces.

SS Prerequisite: Construction Activity Pollution Prevention

Requirements: Create and implement erosion and sedimentation control plan for all construction activities. The project team strategies must meet either of the following standards, erring on the side of whichever is more stringent:

1) 2012 EPA Construction General Permit, OR

2) Local erosion and sedimentation codes

***Technologies/Strategies: To reduce the impact of construction activities, the project team may pursue strategies including temporary and permanent seeding, mulching, earthen dikes, silt fencing, sediment traps and sediment basins. Each of these strategies aims to protect the site’s natural soil structure, air quality surrounding the site and any contiguous water bodies or natural habitats that may be near the site.***

SS Credit: Site Assessment

Requirements: The project team should complete and document a site survey or assessment that includes the following information: topography, hydrology, climate, vegetation, soils, human use and/or human health effects.

The survey or assessment should demonstrate the relationships between the site features and how they influenced the project design.

Page 6: Leed Flashcards

SS Credit: Site Development - Protect or Restore Habitat

Requirements: Maintain at least 40% of any Greenfield land (if any) on the site. The project team must also meet one of two additional options: 1) Restore 30% (including the building footprint) of all portions of the site identified as previously developed or 2) Provide financial support equivalent to at least $0.40 cents per square foot for the total site area (including the building footprint) to a nationally or locally recognized land trust or conservation organization within the same EPA ecoregion or the project’s state.

EP: By doubling the requirements in either Option 1 or Option 2, the project may earn an additional point.

SS Credit: Open Space

Requirements: Provide outdoor space greater than or equal to 30% of the total site area (including the building footprint). A minimum of 25% of that outdoor space must be vegetated (turf grass does not count) or have overhead vegetated canopy.

While the other 75% (of the 30% of total site area) may be paved, a preferred method of accomplishing the credit would be to use permeable surfaces that allow rainwater to pass through (as described in the Rainwater Management credit, below), and that also encourage social activities, physical activity and visual interest.

Page 7: Leed Flashcards

SS Credit: RainwaterManagement

Requirements: There are two options to fulfill this credit: 1) use Low Impact Development (aka “LID”) and green infrastructure (aka “GI”) or 2) manage the post project construction runoff to pre-construction levels.

Strategies to accomplish this include minimizing land disturbance, preserving vegetation, using vegetated swales (aka “Bioswales”), adding bioretention areas, porous/pervious paving, rain gardens and pervious decking.

EP: Project teams may earn an additional point by managing 100% of rainwater within project boundaries.

SS Credit: Heat Island Reduction

Requirements: There are two options for achieving the Heat Island Reduction Credit, 1) “Non-Roof” involves using plants, open grid paving systems or a highly reflective surface or 2) “Parking Under Cover” which involves covering at least 75% of any parking on site with a vegetated roof, renewable energy system or highly reflective surface. Renewable energy systems may be solar photovoltaics, wind turbines or other on-site renewable energy systems.

***Remember that for certain surfaces that are considered “Highly Reflective” they should have a score on the Solar Reflectance Index (SRI) of 82 for a low-sloped roof, or 39 for a steep sloped roof. Since the reflectance of roofs degrades over time (making them less reflective and more prone to absorbing heat), there is an “aging” component to the SRI score. For low and high-sloped roofs, the 3-year aged scores are 64 and 32, respectively.***

EP: By achieving both Option 1 and Option 2 AND locate 100% of parking under cover.

Page 8: Leed Flashcards

SS Credit: Light Pollution Reduction

Requirements: Using the “BUG Method” (Backlight Uplight Glare), or the “Calculation Method” meet uplight and Light Trespass requirements as determined by IES-TM 15-11, Addendum A.

Note that in the Sustainable Sites category, larger projects, such as those registered under LEED for Neighborhood Development or Schools, may benefit from additional opportunities to earn points for large “Site Master Plans” and by leveraging facilities for multiple uses (to reduce the need for additional facilities).

In LEED for Healthcare projects, project teams are rewarded for providing “Places of Respite”, or places for building occupants (both employees and patients) to seek quiet healing while connecting with the environment, as well as direct access to the outdoor environment.

Water Efficiency Prerequisite: Outdoor Water Use Reduction

Requirements: Project teams have two options to fulfill this prerequisite: 1) use No Irrigation, or 2) use Reduce Irrigation by 30% from the baseline, which is determined by the EPA WaterSense Budget Tool.

Nonvegetated surfaces, such as permeable or impermeable pavement, should be excluded from landscape area calculations. Athletic fields and playgrounds (if vegetated) and food gardens may be included or excluded at the project team’s discretion.

Strategies:

• Drought tolerant species: Xeriscaping (plants that require little or no water), herbaceous perennials

• Plant density

• Irrigation efficiency: Drip irrigation, weather sensing systems

• Non-potable water reuse: Graywater reuse, rainwater catchment, treated nonpotable water

Page 9: Leed Flashcards

Water Efficiency Prerequisite:Indoor Water Use Reduction

Requirements: Use 20% less water than the baseline. To achieve this, project teams should specify that all newly installed toilets, urinals, private lavatory faucets, and showerheads be WaterSense labeled (or a local equivalent for projects outside the U.S.).

WaterSense is an EPA program that labels fixtures that use about 20% less water than other products on the market.

Fixture baselines are based on:

1) Energy Policy Act (EPAct) 1992 and 2005

2) Uniform Plumbing Code

3) International Plumbing Code

Fixtures must use 20% less water than the following baselines:

****see table in packet

Water Efficiency Prerequisite: Building Level Water Metering

Requirements: To achieve this prerequisite, project teams must 1) Install permanent water meters in building and on grounds AND 2) commit to sharing water data with USGBC for 5 years after certification or occupancy, whichever is first

Page 10: Leed Flashcards

Water Efficiency Credit: Outdoor Water Use Reduction

Requirements: There are two options for project teams to earn this credit: 1) Use “No Irrigation” or 2) Use “Reduced Irrigation”. In option 1, show that the building does not require irrigation. In option 2, reduce water irrigation requirements by at least 50% from the baseline in peak watering.

As with other prerequisites and credits, the EPA’s WaterSense Budget Tool should be used to calculate savings.

Strategies: Primary strategies should include xeriscaping or drought resistant plant species. Alternative water sources should be considered as should smart water sourcing technologies.

Nonvegetated surfaces, such as permeable or impermeable pavement, should be excluded from landscape area calculations.

Athletic fields and playgrounds (if vegetated) and food gardens may be included or excluded at the project team’s discretion.

Water Efficiency Credit: Indoor Water Use Reduction

Requirements: Project teams may earn this credit, and incrementally higher points for reducing water use by 25% - 50%

25% = 1 point

30% = 2 points

35% = 3 points

40% = 4 points

45% = 5 points

50% = 6 points (except Hospitality, Schools, Retail, Healthcare)

EP: Indoor Water Use Reduction may earn exemplary performance by achieving 55% water use reduction.

Page 11: Leed Flashcards

WE Calculations: Full Time Equivalent (FTE) Occupants

Daily averages take into account all the occupants of a given type for a typical 24-hour day of operation.

Peak totals are measured at the moment in a typical 24-hour period when the highest number of a given occupant type is present.

The calculation for FTE employees is:

FTE employees = Full-time employees + (Σ daily part-time employee hours / 8)

In buildings with irregular occupancy patterns, a better calculation is:

FTE employees = (Σ all employee hours / 8)

These show that each part time employee is worth a fraction of a full time employee. One who works 20 hours per week is 1/2 a full time employee (40 hours per week).

Regular building occupants include: • Full time employees/staff • Part time employees/staff • Residents • Primary and secondary school students • Hotel guests • Inpatients • Visitors include: • Retail

customers Outpatients • Volunteers • Higher education students

Water Efficiency Credit: Building Level Water Metering

Requirements: Project teams should go beyond building macro level building water metering and install permanent water meters for two or more subsystems such as irrigation, plumbing fixtures and fittings, domestic hot water, boiler, reclaimed water, or other process water.

Page 12: Leed Flashcards

Water Efficiency Credit: Cooling Tower Water Use

Requirements: To achieve this credit project teams should conduct a one-time potable water analysis, in order to optimize cooling tower cycles. Measure at least the five control parameters:

1. Ca (as CaCO3)

2. Total alkalinity

3. SiO2

4. Cl-

5. Conductivity

ASHRAE 189.1 is referenced in Indoor Water Use Reduction for cooling tower and evaporative condenser requirements.

Energy and Atmosphere Prerequisite: Fundamental

Commissioning and Verification

****Note: Commissioning and/or building systems “verification” should improve the building’s energy use, operational costs, occupant comfort, etc.****

LEED not only requires commissioning as a prerequisite to every building certification, but also offers additional points for projects that complete advanced levels of commissioning. It is considered to be best practice to engage the CxA as early as possible in the design process.

Requirements: To earn this credit, project teams should designate an individual as the Commissioning Authority (CxA). This individual should have commissioning experience and be unrelated to the project design/construction management. The CxA reviews owner’s project requirements (OPR) and basis of design (BOD) and develops commissioning plan. Subsequently, the CxA verifies installation/performance of energy systems and completes a commissioning report.

Commissioned Systems:

• HVAC&R (Heating, Ventilation, Air Conditioning and Refrigeration)

• Electrical systems including distribution, lighting and daylighting controls

• Plumbing systems including - Domestic hot water, pumps and controls

• Renewable energy systems

Page 13: Leed Flashcards

EA Prerequisite: Minimum Energy Performance

***Referenced Standards:

•ASHRAE/IESNA Standard 90.1-2010 (BD+C) - For LEED BD+C projects.

•ENERGY STAR from the Environmental Protection Agency/EPA (EBOM) - For LEED O+M projects.

ASHRAE stands for the American Society of Heating, Refrigeration and Air Conditioning Engineers and IESNA stands for Illuminating Engineering Society of North America.***

Requirements: Project teams compare the proposed building’s energy performance to a baseline and demonstrate a 5% (for New Construction projects) improvement in the proposed building energy efficiency. There are three options to fulfill this prerequisite:• Option 1: Whole Building Energy Simulation - baseline as per ASHRAE/IESNA Standard 90.1-2010 (BD+C)• Option 2: ASHRAE Advanced Energy Design Guides (prescriptive)• Option 3: Advanced Buildings Core Performance Guide (prescriptive)

EA Prerequisite: Building-Level Energy Metering

Requirements: Project teams pursue a strategy to install new (or use existing buildinglevel energy meters or submeters) that provide data representing total building energy consumption AND commit to sharing the data with USGBC for 5 years or till the building ownership and/or lessee changes.

Page 14: Leed Flashcards

EA Prerequisite: Fundamental Refrigerant Management

Purpose/Intent: To reduce stratospheric ozone depletion.****Reference: Montreal Protocol, an international treaty that required:By 2010: Phase out CFCsBy 2030: Phase out HCFCs

Understanding the Montreal Protocol and its implications is important. Also understanding that while all synthetic refrigerants are worse than natural refrigerants (such as water, CO2, propane, butane, isopentane and ammonia) USGBC considers HFCs to be the worst in terms of their impact on Global Warming.****

Requirements:New Building: Zero use of CFC refrigerants in HVAC&RExisting Building: CFC phase-out prior to project completion

****see table

EA Credit: EnhancedCommissioning

Requirements: Note: To fulfill the “Enhanced Commissioning” credit, the CxA can be the owner of the project or the owner’s representative or a subconsultant to the architecture or engineering firm.

Employees of architecture or construction firm cannot assume the role of CXA for enhanced commissioning.

Page 15: Leed Flashcards

EA Credit: Optimize EnergyPerformance

***Purpose/Intent: To achieve incremental levels of energy efficiency beyond the prerequisite requirements.

Note: This credit is the “Where the Prius Tire Rubber Meets the Road” (so to speak) in terms of energy performance and the number of points that may be earned by a LEED project. More points may be earned here than anywhere else.***

By pursuing Option 1 below, LEED BD+C projects may earn as many as 18 points with this credit, or as many as 16 or 20 points, in the Schools and Healthcare rating systems, respectively. Fewer, but not an insignificant number of points, is available for projects that pursue this credit under Option 2.

Requirements: There are two options for project teams may pursue to seek improvement in energy efficiency compared to the building baseline: Option 1) pursue a Whole Building Energy Simulation, or 2) pursue “Prescriptive Compliance” whereby project teams comply with ASHRAE 50% Advanced Energy Design Guides.

Existing Buildings (O+M projects): Use ENERGY STAR to measure compliance with a score above 75 in ENERGY STAR’s Portfolio Manager Tool.

International projects: Use ASHRAE Standard 90.1. Existing building projects that are not eligible for ENERGY STAR should benchmark against national data averages or historical data. Note: For projects to pursue Option 2, the project team must also pursue “Option 2” in the Minimum Energy Performance prerequisite.

EP: Achieve at least 54% energy savings (in New Construction, Major Renovation and Core and Shell projects)

EA Credit: Advanced Energy Metering

Requirements: Project teams should install advanced energy metering technologies for (1) all whole-building energy sources and (2) any individual energy end uses that represent 10% or more of the total annual energy consumption.

Page 16: Leed Flashcards

EA Credit: Demand Response

Requirements: Project teams may pursue one of two DR options 1) Load shedding, or 2) Load Shifting. Note: Demand Response is a concept related to the “Smart Grid” whereby utilities may reduce demand (and buildings may benefit through financial incentives) on the fly as necessary during a peak demand “event”.

Note: Using an on-site generator to produce power during an energy load shedding or shifting event is not an eligible strategy for fulfilling this credit. Teams must commit to a DR program with a minimum of a one-year contract to shed or shift at least 10% of peak electricity demand. If a DR program is not currently available where the building is located, teams may put in place infrastructure to take advantage of future demand response programs or dynamic, real-time pricing programs.

EA Credit: Renewable Energy Production

***Requirements: Project teams have several renewable energy systems options to offset building energy costs. The calculation for determining the building’s annual energy costs should use the following: A) Numerator = the dollar value (equivalent energy cost) of usable energy produced by the renewable energy system and B) Denominator = the total building annual energy cost.

The result of this equation will provide you with the % of renewable energy (by cost) that the renewable energy system can produce.***Allowable sources for renewable energy include the following:1. Photovoltaic (building should own the system, or may lease if the lease is for atleast 10 years) 2. Solar thermal 3. Wind 4. Biofuel (untreated wood waste - including mill residue, agricultural crops, animal or organic waste, landfill gas) 5. Low-impact hydroelectricity 6. Wave and tidal energy 7. Geothermal energy (heating and electric)

Not acceptable for renewable energy production are:1. Geo-exchange\ 2. Passive solar 3. Landfill trash (incineration) 4. Forestry biomass (other than mill residue) 5. Wood coated with paints or plasticNote: This credit uses energy cost as a measure, not energy consumption or production in units of kWh, Therms or some other measure.

Page 17: Leed Flashcards

EA Credit: Enhanced Refrigerant Management

Requirements: Project teams have two options to fulfill this credit: 1) Use No Refrigerants or natural refrigerants (as described in the prerequisite above), or 2) Calculate and minimize refrigerant impact by selecting appropriate, low-impactrefrigerants.

EA Credit: Green Power and Carbon Offsets

Requirements: Engage in at least a 5-year renewable energy contract to provide 50% or 100% of building’s energy use from green power, carbon offsets, or renewable energy certificates (RECs). RECs (aka Green Tags, or Renewable Energy Credits) are tradable commodities representing proof that one megawatt hour (MWh) of electricity was generated by a legitimate renewable energy source.

Green power and RECs must be Green-e Certified (Center for Resource Solutions) Ex. Renewable energy certificates (RECs), tradable renewable certificates (TRCs), green tags. Carbon offsets must be Green-e Climate Certified.The baseline1) Annual electricity consumption from EA Prerequisite, Minimum EnergyPerformance OR2) U.S. Department of Energy’s Commercial Building Energy Consumption SurveyNote: Based on energy consumption, not cost

MR Prerequisite: Storage and Collection of Recyclables

Requirements: Project teams are required to, at a minimum, recycle: Metal, Glass, Mixed Paper, Plastic and Corrugated Cardboard. In addition, project teams should make efforts for the safe collection, storage and disposal of two of the following: Batteries, mercury-containing lamps (such as CFLs or fluorescent tubes, T5s, T8s, T12s, etc.) and electronic waste (aka “ewaste”).

MR Prerequisite: Construction and Demolition Waste Management Planning

Requirements: Project teams should develop and implement a construction and demolition waste management plan and define waste diversion goals for the project by identifying at least five building materials (both structural and nonstructural) to divert from landfills. Specify whether materials will be separated or commingled.

Page 19: Leed Flashcards

MR Credit: Building Life-Cycle Impact Reduction

Requirements:Option 1: Historic Building Reuse (5 points)Option 2: Renovation of Abandoned or Blighted Building (5 points)Option 3: Building and Material Reuse (2-4 points)Option 4: Whole-Building Life-Cycle Assessment (3 points)

EP: Reuse 95% of the building in Option 3; or achieve any improvement over the required credit thresholds in all six (6) impact categories.

MR Credit: Building Product Disclosure and Optimization

(BPDO) - Environmental Product Declarations

Requirements: Project teams have two options for complying with this credit: Option 1) Environmental Product Declarations: choose 20 products (from 5 different manufacturers) that offer “Environmental Product Declarations”, or Option 2) Multi-Attribute Optimization: Use products with “Multi-Attribute Optimization” for 50%, by cost, of the total value of permanently installed products in the project.

***Note: Product claim validations, certifications and standards are related concepts, but they are not the same. Validation of a product’s attributes simply confirms a product’s claim. Certification is a more rigorous form of validation. Certifications rely on established standards, such as ANSI (the“American National Standards Institute”) and ISO (the “International Standards Organization”).**

Multi-Attribute Labels (Certifications) offer more comprehensive review of products and their makeup than Single Attribute labels (Certifications). Multi-Attribute Labels are offered from organizations such as EcoLogo. An example of a single attribute certification would be the Forest Stewardship Council (FSC). Environmental Product Declarations (EPDs) are available from organizations such as UL Environment.

USGBC/LEED views “Industry Wide” EPDs to be worth 1/2 of a product(for the purposes of fulfilling the EPD credit. “Product specific” EPDs are valued as one whole product for purposes of fulfilling the EPD credit.

Note: USGBC is rewarding regional products here by encouraging project teams to use products that are sourced within 100 miles of the project site by valuing them at 200% of their contributing cost.

Page 20: Leed Flashcards

MR Credit: Building Product Disclosure and Optimization

(BPDO) - Sourcing of Raw Materials

Requirements: Project teams have two options for fulfilling this credit: Option 1) “Raw Materials Source Reporting” in which teams use at least 20 different products from 5 separate manufacturers that disclose supplier extraction locations and commit to responsible land use or Option 2) “Leadership Extraction Practices” in which the project uses at least 25% (by cost) of total value of permanently installed building products thatcomply with at least one of the following criteria:• Extended producer responsibility: Products purchased from a manufacturer who participates in an extended producer responsibility program OR is directly responsible for their extended producer responsibility• Bio-based materials: Products must meet the Sustainable AgricultureNetwork’s Sustainable Agriculture Standard.

Indoor Environmental Quality Credit: Interior Lighting

Requirements: Project teams have two options to earn this credit:Option 1) “Lighting Controls” offer individual controls for at least 90% of building occupants, with at least three levels of control: on, off and midlevel. Include lighting control in all shared multi-occupant building spaces.

Option 2) “Lighting Quality” use light sources with a CRI of at least 80 and minimize “direct only” overhead lighting to 25% or less of total connected lighting for all regularly occupied spaces. Use light sources that have a rated life of at least 24,000 hours for 75% of total connected lighting load.

Indoor Environmental Quality Credit: Daylight

Requirements: Project teams may demonstrate through computer aided simulation that designs achieve appropriate sunlight exposure.

Also teams should provide manual or automatic glare-control devices for all regularly occupied spaces.

Indoor Environmental Quality Credit: Quality Views

Requirements: Achieve a direct line of sight to the outdoors viavision glazing for 75% of all regularly occupied floor area. 75% of all regularly occupied floor area must have at least two of the four following kinds of views:

a) Multiple lines of sight to visionglazing in different directions at least 90 degrees apart.

b) Views that include at least two of the following: (1) flora, fauna, or sky; (2) movement; and (3) objects at least 25 feet from the exterior of the glazing

c) Unobstructed views located within the distance of three times the head height of the vision glazing

d) Views into interior atria may be used to meet up to 30% of the required area.

EP: Project teams that meet the requirements for 90% of all regularly occupied areas are eligible for an EP point.

Indoor Environmental Quality Credit: Acoustic

Performance

Requirements: Similar to the concepts mentioned above regarding LEED forSchools, the project team should aim to fulfill this credit by eliminating background noise, reducing sound transmission and/or reverberation and echo, and improving indoor sound characteristics through a variety of strategies.a) HVAC Background Noise: Achieve maximum background noise levelsfrom heating, ventilating, and air conditioning (HVAC) systems per 2011 ASHRAE Handbook, HVAC Applications, Chapter 48, Table 1; AHRI Standard 885-2008, Table 15; or a local equivalent. Calculate or measure sound levels.

b) Sound Transmission: Meet the composite sound transmission class (STCC) ratings listed in Table 1, or local building code, whichever is more stringent.

c) Sound Reverberation Time: Meet the reverberation time requirements in theASHRAE “Performance Measurement Protocols for Commercial Buildings”, Chapter 9.

d) Sound Reinforcement: For all large conference rooms and auditoriums seating more than 50 persons, evaluate whether sound reinforcement and AV playback capabilities are needed.

e) Masking Systems: For projects that use masking systems, the design levels must not exceed 48 dBA. Ensure that loudspeaker coverage provides uniformity of +/–2 dBA and that speech spectra are effectively masked.
