To reduce adverse environmental effects from energy used for operating public infrastructure.
Design, purchase, or work with the local government to install all new infrastructure, including but not limited to traffic lights, street lights, and water and wastewater pumps, to achieve a 15% annual energy reduction below an estimated baseline energy use for this infrastructure. The baseline is calculated with the assumed use of lowest first-cost infrastructure items.
The calculation of the baseline does not seem very clear for us. Does it mean that we have to calculate the energy used by the cheapest equipment?
Alicia, you're correct that the GIBc13 baseline must equate to the energy use of the cheapest available equipment, and note that it must be the cheapest in first-cost, not life-cycle costEconomic cost of a product or building over its expected life, including first cost, operating cost, and, when appropriate, cost of disposal or demolition.. The presumption is that least first-cost items are generally also the least energy efficient.
