CUMULATIVE ENERGY DEMAND AND CUMULATIVE CO2 EMISSIONS BY A REFURBISHMENT OF OLD BUILDINGS

摘要

The aim of this contribution is to show examples for the integration of Cumulative Energy Demand (CED) and Cumulative CO{sub}2 Emissions (CE{sub}(CO{sub}2)) in the refurbishment of old buildings. Under consideration of effects for the developing of buildings the Energy Pay Back Time (EPBT) will be calculated. Thus, next to the CED and the Green House Gases (GHG) emissions (CO{sub}2) the EPBT permits time a direct comparison of different versions of the refurbishment.
