Research on demonstration project technology roadmap of zero energy buildings abroad

Analyses several zero energy (or nearly zero energy) building cases for low-rise residential buildings, multi-rise residential buildings, public buildings and communities in US, UK, Germany, France, etc. These buildings are mostly built completely and actual measurement data for most of them are collected. For a small part of the buildings, simulation calculation is used to get data. Presents recent development in solar energy photovoltaic technology, high performance building envelope and other support technology aimed at realizing zero energy building, as well as the economical efficiency analysis of some demonstration projects. Proposes the integration application of passive design, high performance building envelope, high performance energy system, energy consumption monitoring system, etc. to achieve the goal of zero energy building.
