Development of system-integrated design prototypes for zero emission buildings

Abstract

This study aims to develop a system-integrated design prototype for realizing zero emission buildings (ZEBs) and to apply the same to standard-model buildings in order to demonstrate the feasibility of ZEBs. Toward this end, we analyzed the energy consumption/CO2 emission performance of various design strategies and component technologies. Residential buildings, office buildings, and school buildings were selected as the building types that will have the greatest ripple effect from the viewpoint of realizing ZEBs. Prototype models using various architectural planning elements, facility planning elements, and renewable energy systems were proposed for each type, and the CO2 emissions reductions were evaluated through an energy performance analysis. The reductions in CO2 emissions for these building types decreased in the order of school buildings (58. 6%) > office buildings (46. 1%) > residential buildings (36. 6%). This study is significant in that currently available technologies were employed as element technologies, and CO2 emissions were evaluated based on the most common buildings.
