Description
EPCdem is responsive to changes in the building site, building envelope and orientation, as well as internal loads in the building. Improving any of these factors will have a positive impact on EPCdem. EPCuse is a building performance indicator that is sensitive to the changes in a building’s HVAC systems and other equipment. The energy performance coefficient for primary energy sources (EPCpri) is a performance indicator sensitive to changes in the method of energy delivery. It is subject to different types of energy delivery, using different types of energy supply networks including electricity, gas, and district cooling. These factors are largely dependent on the city infrastructure and in the region the prevalent networks are electricity from large, gas-fired power plants and chilled water delivery by district cooling plants. The energy performance for CO2 emissions (EPCCO2) is a performance indicator sensitive to changes in the method of energy delivery. It is subject to different types of energy delivery, using different types of energy supply networks including electricity, gas, and district cooling.
Objective
To minimize the building energy demand through the establishment of GSAS thermal energy demand performance, to minimize the building energy use through the establishment of GSAS energy use performance, to reduce the dependence on fossil-based primary energy supply and delivery network through the establishment of GSAS primary energy performance, and to establish CO2 emissions performance associated with the primary energy supply and delivery network.
