TCAAP Energy Integration Resiliency Framework <br />Energy Efficiency Strategies <br /> <br /> <br /> 63 <br /> Insulation, air sealing, and passive solar design to reduce space conditioning load to 10 <br />Btu/hr/square foot <br /> Ground source heat pump technology (electric driven) <br /> High-efficiency appliances such as refrigerators, dishwashers, washer/dryers (with additional <br />consideration of low water use) <br /> Consideration of heat pump dryers <br /> Propane on localized natural gas stoves and grills <br /> Magnified benefit from rooftop PV electricity or purchase of community solar shares <br />Some marketing benefits of implementing these solutions include: <br /> Availability of high-tech, low maintenance equipment <br /> Cutting edge all-electric design <br /> True net-zero or net-zero ready potential <br /> Low-cost energy living <br />Low Load Home Performance Verification <br />Coordination between ground water system capacity and home design will be necessary up-front and <br />on an ongoing basis. This will provide developers and users with the necessary assurance that the <br />designed loads will be compatible with the capacity of the system. Verification of home energy design <br />and performance can most easily be achieved by a third-party with design and construction expertise. <br />The County and JDA could specify building standards to help homes reach these performance targets, <br />such as SB 2030, which has standards for single-family homes that could be personalized for TCAAP. <br />This program could be administered between utility energy-efficiency verification programs like Energy <br />Star for New Homes and coordination help from the City’s inspection division. <br />4.3.1.1. Case Studies <br />Zero Carbon Residential Development | Bainbridge Island, Washington <br />Bainbridge Island is a mixed residential development of 24 single-family homes, rental apartments, <br />senior-living, and condos. Buildings were designed to meet the criteria of a stringent building <br />certification program, the Living Building Challenge, and included “ultra-insulated” envelopes, high- <br />efficiency appliances, and an opt-in opportunity to buy or finance roof-top solar. Mini-split heat pumps <br />with energy recovery ventilators provide high-efficiency heating. Additionally, all parking is <br />underground and broader sustainability innovations are woven in such as walkability, water
