• Reduce the energy use (and environmental impact) of buildings 20% or more below the level of a standard building.
• Use onsite renewable energy to supply a portion of the building's electrical and gas (thermal energy) needs, using solar photovoltaic (PV) panels or solar water heating.
• Commission the building by verifying the functional performance of all energy-using systems after they are installed but before the building is occupied.
• Reduce the use of ozone-harming and global-warming chemicals in building refrigeration and air-conditioning systems.
• Provide a means to troubleshoot the building's energy use on a continuing basis by installing measuring and monitoring devices.
• Supply 35% or more of the building's electrical supply with purchased green power from offsite installations, typically from wind farms.
