APPLICATIONS FOR LARGE RESIDENTIAL COMMUNITIES:WHAT IS NET-ZERO ENERGY?

摘要

In the building industry, the term Zero Energy Homern(ZEH) or building can be interpreted in a variety of ways.rnAnd it is not simply a semantic argument: targeting onerndefinition versus another can have significant impacts onrnbuilding practices, utility demand profiles and constructionrnprograms and policies. Therefore, it is important to reviewrnthe different definitions of “zero” and the relevant benefitsrnand shortcomings of each. This paper will review threernprimary “ZEH” definitions – zero peak, zero net-electricityrnand zero net-energy – and how community-scalernimplementations of these strategies can improve cost-effectivenessrnwhile enhancing zero energy and zero peakrnbenefits.
