Heat savings in buildings in a 100% renewable heat and power system in Denmark with different shares of district heating

摘要: Abstract The paper examines implementation of heat saving measures in buildings 2050, under the assumption that and power supply comes solely from renewable resources Denmark. Balmorel – a linear optimisation model sectors Denmark is used for investigating economically viable levels savings, which can be implemented by reducing transmission losses through building elements installing ventilation systems with recovery, different future Danish system scenarios. Today almost 50% demand covered district heating. A further expansion heating network assessed penetration savings analysed this context. If all measures, included model, are implemented, 2050 could reduced around 40%. Results show it cost effective to reduce approximately 12% 17% depending on assumed lifetime costs measures. Individual areas have higher than areas. When expanded, an overall slightly decreases along lower capacity investments costs.
