Energy usage and technical potential for energy saving measures in the Swedish residential building stock

摘要

This paper provides an analysis of the current energy usage (net energy and final energy by fuels) and associated carbon dioxide (CO_2) emissions of the Swedish residential building stock, which includes single-family dwellings and multi-family dwellings. Twelve energy saving measures (ESMs) are assessed using a bottom-up modeling methodology, in which the Swedish residential stock is represented by a sample of 1400 buildings (based on data from the year 2005). Application of the ESMs studied gives a maximum technical reduction potential in energy demand of 53%, corresponding to a 63% reduction in CO_2 emissions. Although application of the investigated ESMs would reduce CO_2 emissions, the measures that reduce electricity consumption for lighting and appliances (LA) will increase CO_2 emissions, since the saved electricity production is less CO_2-intensive than the fuel mix used for the increased space heating required to make up for the loss in indirect heating obtained from LA.
