To improve the energy efficiency of city services.
Attempt any of the following options for a maximum of 4 points:
Path 1: Street Lighting and public area lighting (2 points)
Street lighting design should meet the efficiency related requirements of ‘ANSI/IESNA RP-8-14 Roadway Lighting’ or internal equivalent standard. In addition, lamps should have a minimum Luminous Efficacy of 100 lumens per watt.
AND / OR
Path 2: Water and Wastewater (2 points)
All pumps used in the water and wastewater systems must meet the Pump Energy Index listed in Table I.1—Proposed Energy Conservation Standards for Pumps, 10 CFR Parts 429 and 431 of DOE standards Federal Register final rule Energy Conservation Program: Energy Conservation Standards for Pumps1 or international equivalent standard.
AND / OR
Path 3: District Energy Systems (1-2 points)
Incorporate a District Energy System (DES). For the purposes of this credit, a DES is a heating and/or cooling system that produces steam, hot water, and/or chilled water in a centralized plant using cogeneration or tri-generation and distributes this energy to multiple buildings. Determine the percentage of city’s electric, cooling and/or heating demand serviced by the DES using the following formula. Single-family residential buildings may be excluded from the calculation.Points are awarded based on percentage of city load supplied by district energy resources as shown in table below.
Table 6. Points for District EnergyDistrict Energy Systems should be planned and designed to cater to the phase-wise development of the city to ensure that the requirements are met at each phase.
