Impacts of Incorporating Electric Vehicle Charging into Zero Net Energy (ZNE) Buildings and Communities

The American Clean Energy and Security Act of 2009 currently on the Senate floor builds upon these targets, calling for “the transformation of the building stock of the United States to zero net energy consumption”(H. [...] The CPUC has developed a unique ZNE definition pertaining to California’s ZNE goals, which expands the ZNE “boundary” from a building to a “project”: “Zero Net Energy is herein defined as the implementation of a combination of building energy efficiency design features and on-site clean distributed generation that result in no net purchases from the electricity or gas grid, at the level of a singl. [...] PV size data is presented for two scenarios: (1) the PV size required to net out building energy only (electricity and natural gas), and (2) the PV size required to net out the combined building energy use and additional PHEV electric charging loads. [...] Conclusions The single home analysis shows that PHEV electric charging loads are approximately 55% of the building electricity load in 2010, and 13% of the total building energy (electricity and natural gas) use. [...] Residential natural gas loads are the largest 1 Community-level impacts shown on an average per-home basis 2 The goal of the CPUC Long Term Energy Efficiency Strategic Plan is for all new homes to be ZNE by 2020 ©2010 ACEEE Summer Study on Energy Efficiency in Buildings 8-321 component of the total building energy use and reducing building natural gas use (e.g.
