Resource summary

Question Answer
EA Credit 1: Enhanced Commissioning requires commissioning activities & requirements in addition to EA Prerequisite 1, Fundamental Commissioning. Requirements: - review contractor submittals - verify inclusion of systems manual requirements in construction documents - Verify inclusion of operator and occupant training requirements in construction documents - Verify systems manual updates and delivery - Verify Operator and occupant training delivery and effectiveness - Verify seasonal testing - Develop an on-going commissioning plan
EA Credit 2: Optimize Energy Performance This is the primary energy efficiency credit which varies significantly across LEED rating systems
Regulated (non-process) energy Generally refers to base building systems such as chillers, boilers, cooling towers, etc
EA Credit 3: Advanced Energy Metering intent: to provide ongoing accountability of building energy consumption over time
Building Automated System (BAS) a computerized, intelligent network of electronic devices, designed to monitor and control the mechanical and lighting systems in a building
System Level Metering Installing sub-meters that measure a subset of energy used for a particular purpose in a building
District Energy Systems A central plant that provides energy to a group of buildings such as a University Campus.
EA Credit 4: Demand Response Design building and equipment for participation in demand response programs through load shedding or shifting
Demand Response Changes in electric usage by end-use customers from their normal consumption patterns in response to fluctuations in the prices of electricity. The goal is to actively engage customers in modifying their consumption in response to pricing signals, shifting their electrical usage from on-peak to off-peak periods
EA Credit 5: Renewable Energy Production Use renewable energy systems to offset building energy costs. Points are awarded for using on-site renewable energy systems to provide a percentage of the building energy cost
What are considered acceptable forms of renewable energy for LEED? - photovoltaics (solar) - wind energy - solar thermal - geothermal heating & electric - low-impact hydro-electric - wave & tidal energy - biofuels: untreated wood waste including mill residue, agricultural crops or waste, animal & other organic waste, landfill gas
What are NOT considered acceptable forms of renewable energy for LEED? - geo-exchange systems - passive solar - burning landfill trash - forestry biomass other than mill residue - wood coated with paints or plastics
EA Credit 6: Enhanced Refrigerant Management What are the two options? Option 1 - do nose use refrigerants at all (mild climates) Option 2 - select refrigerants and HVAC&R that minimize Ozone Depletion Potential and Global Warming Potential
EA Credit 7: Green Power & Carbon Offsets requires projects to offset carbon emissions from a percentage of the building's electricity usage by purchasing Green Power. The green power purchases must be for 5 years and must be Green-e Certified
Renewable Energy Certificates tradable commodities that represent one megawatt hour (MWh) of renewable electricity generated and delivered somewhere on a power grid. Each MWh of clean renewable electricity results in one less MWh of traditional (dirty) power. RECs encourage the use of grid source, renewable technologies on a net zero pollution basis

MR Prerequisite 1: Storage & Collection of Recyclables Projects must provide an area of the building to dedicate to recycling. At a minimum, the following 5 items must be recycled: - paper - corrugated cardboard - glass - plastics - metals
MR Prerequisite 2: Construction & Demolition Waste Management Develop and implement a construction and demolition waste management plan that includes the following: - establishes waste diversion goals for the project by identifying at least five materials targeted for diversion - specifies whether materials will be separated or commingled and describe the diversion strategies planned for the project. describe where the material will be taken and how the recycling facility will process the material
Alternative Daily Cover (ADC) refers to material other than soil placed on the surface of the active face of a municipal solid waste landfill at the end of each operating day to control vectors, fires, odors, blowing litter, and scavenging. Includes processed green materials, sludge, ash and kiln residue, compost, construction and demolition debris, and special foams and fabrics
MR Credit 1: Building Life-Cycle Impact Reduction Demonstrate reduced environmental effects during initial project decision-making by reusing existing building resources or demonstrating a reduction in materials use through life-cycle assessment points are awarded for: - historic building reuse - renovation of abandoned or blighted building - building and material reuse - whole-building life-cycle assessment
Life Cycle Assessment (LCA) the evaluation of the environmental impacts of a given product or service, taking into account the whole life of a product or project from cradle to grave
MR Credit 2: Building Product Disclosure & Optimization - Environmental Product Declaration Use permanently installed products that have publicly published Environmental Product Declaration
Environmental Product Declaration (EPD) a verified document that reports environmental data of products based on life cycle assessment (LCA) and other relevant information and in accordance with the international standards.
MR Credit 3: Building Product Disclosure & Optimization - Sourcing of Raw Materials What are the 2 options? Option 1 - Raw Material Source and Extraction Reporting use permanently installed products that have publicly released a report from their raw material suppliers which include raw material supplier extraction locations, a commitment to long-term ecologically responsible land use, a commitment to reducing environmental harms from extraction and/or manufacturing processes, and a commitment to meeting applicabel standards or programs voluntarily that address responsble sourcing criterial Option 2 - Leadership Extraction Practices Use products that meet at least one of the responsible extraction criteria below for at least 25%, by cost, of the total value of permanently installed building products in the project
Extraction criterial definitions Extended producer responsibility - products purchased from a manufacturer that participates in an extended producer responsbility program bio-based materials- must meet the sustainable agriculture network's sustainable agriculture standard wood products - must be certified by the Forest Stewardship Council or USGBC-approved equivalent Materials reuse - reuse includes salvaged, refurbished, or reused products recycled content - recycled content is the sum of post-consumer recycled content plus one-half the pre-consumer recycled content, based on cost regional materials - products extracted, manufactured, purchased, within 100 miles of the project USGBG approved program - other
MR Credit 4: Building Product Disclosure & Optimization Option 1 - use permanently installed products that are USGBG approved programs to demonstrate the chemical inventory of the product
Health Product Declaration (HBD) provide a full disclosure of the potential chemicals of concern in products by comparing product ingredients to a wide variety of 'hazard' lists published by government authorities and scientific associations
Cradle to Cradle an environmental approach to the design of products. A holistic, economic, industrial, and social framework that seeks to create systems that are not only efficient but also essentially waste free.
