91 EA Credit Demand Response

92 Energy Efficiency Measures are permanent and reduce the facility s annual energy consumption (in kilowatt hours) and/or electrical demand. Demand Response Measures are temporary and reduce a customer s demand (in kilowatts) during brief, infrequent periods.

93 EA Credit: Demand Response Case 1. 2 Points Demand response program available or Case 2. 1 Point Demand response program not available

94 Enrolment 1 year 10% estimated peak demand

95 Design the building in a manner that enables it to participate in a demand response program

96 3 Types of Demand Response Systems: 1. Manual 2. Semi-Automated 3. Fully-Automated

97 Level Manual demand response Uses BAS? No How Response Occurs People manually turn off lights and equipment when asked to do so. Semi-automated demand response Yes A person initiates a control strategy preprogrammed into the BAS when a demand response event is called. Fully automated demand response ( AutoDR ) Yes Receipt of an external price, reliability, or event signal automatically triggers a BAS control sequence that switches the building to low- power mode; no human intervention is required.

114 What is Green Power

115 Implementation

116 Building's electricity use: 1,000,000 kwh/yr 1,000,000 kwh/yr X 50% annually for 5 years

117 GHG emissions (CO 2 e) = Consumption x CO 2 emissions factor

118 Direct Emissions Burned at the building Indirect Emissions Energy from utilities

119 Energy Simulation or CBECS database

120

121 Calculations GHG emissions (CO 2 e) = Consumption x CO 2 emissions factor

122 Example Project: 5,000,000 kwh / year 1,000,000 kbtu Direct GHG Emission Factor Natural Gas: 5.32 x 10-5 Mt CO 2 e / kbtu 1,000,000 kbtu x 5.32 x 10-5 Mt CO 2 e / kbtu = 53.2 Mt CO 2 e / year

123 Example Project: 5,000,000 kwh / year 1,000,000 kbtu Indirect GHG Emission Factor Purchased electricity: 5.90 x 10-4 Mt CO 2 e / kwh 5,000,000 kwh x 5.90 x 10-4 Mt CO 2 e / kwh = 2,950 Mt CO 2 e / year

124 Direct (natural gas): Indirect (grid electricity): Minimum credit req: Total offset: 53.2 Mt CO 2 e / year + 2,950 Mt CO 2 e / year = 3,003 Mt CO 2 e / year X 50% = 1,501.5 Mt CO 2 e / year
