Energy and Atmosphere Goal Reduce the Environmental Impacts associated with Energy Use.
Energy and Atmosphere ENERGY STAR Portfolio Manageran interactive, online management tool that supports tracking and assessment of energy and water consumption. ENERGY STAR ratinga measure of a building's energy performance compared with that of similar buildings, as determined by the ENERGY STAR Portfolio Manager. A score of 50 represents average building performance.
Energy and Atmosphere Portfolio Manager is an interactive energy management tool that allows you to track and assess energy and water consumption across your entire portfolio of buildings in a secure online environment.
Energy and Atmosphere • Following an integrated process helps identify synergistic strategies for the following areas: • Energy demand • Energy efficiency • Renewable energy • Ongoing performance
Energy and Atmosphere • Energy Demand • Reduce Demand • Utilize sustainable methods for meeting energy needs
Energy and Atmosphere • Refrigerants • Substances used in cooling of systems • Chlorofluorocarbon (CFC) refrigerants • Montreal Protocol of 2010 • hydrochlorofluorocarbon (HCFC) refrigerants • Montreal Protocol of 2030
Energy and Atmosphere • Refrigerants • CFCs and HCFCs are organic chemical compounds known to have ozone-depleting potential. • To achieve LEED certification, new buildings may not use CFC-based refrigerants, and existing buildings must complete a total CFC phase-out prior to project completion.
Energy and Atmosphere • Strategies • Commissioning • Monitoring
Energy and Atmosphere LEED for Homes The LEED for Homes rating system includes an adjustment to compensate for the effect of square footage on resource consumption by adjusting the point thresholds for Certified, Silver, Gold, and Platinum ratings based on home size. The adjustment applies to all LEED for Homes credits, not just to strategies related to Energy and Atmosphere. LEED for Homes is currently the only LEED rating system with this type of adjustment.
Energy and Atmosphere • Energy Efficiency • energy efficiency using less energy to accomplish the same amount of work. • building envelope the exterior surface of a building-the walls, windows, roof, and floor; also referred to as the building shell.
Energy and Atmosphere Renewable Energy green power is typically understood to include: Solar Wind Wave Biomass Geothermal power Low impact hydropower
Energy and Atmosphere Renewable Energy non renewable fuels: Coal Nuclear power Oil Natural gas
Energy and Atmosphere Renewable Energy LEED distinguishes between on-site renewable energy production and purchase of off-site green power.
Energy and Atmosphere Renewable Energy On-site energy production typically involves a system that generates clean electricity, such as solar photovoltaic panels that convert the sun's energy into electricity.
Energy and Atmosphere Renewable Energy Off-site renewable energy is typically purchased at a premium price per kilowatt-hour from a utility or a provider of renewable energy certificates (RECs).
Energy and Atmosphere • On-Going Energy Performance • It is critical to ensure that a project functions as designed and that it sustains and improves this performance over time. • Monitoring and verificationprovide the basis for tracking energy performance, with the goal of identifying and resolving any problems that may arise.
Energy and Atmosphere • On-Going Energy Performance • commissioning (Cx) the process of verifying and documenting that a building and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the owner's project requirements. • The cost of commissioning is often repaid with recovered energy performance. • Commissioning is one of the most cost effective means of improving energy efficiency in commercial buildings.
