District heating energy efficiency of Danish building typologies

摘要: Abstract This paper provides a state-of-the-art and freely available online overview of the district heating (DH) efficiency Danish building typologies. The is based on DH consumption data from 42 969 buildings constructed up until 2017 that in combination with Building Dwelling Register constitutes dataset previously unseen level detail, confidence, sample size, research opportunities. also presents an initial analysis terms three indicators, namely 1) Annual energy use intensity, 2) Daily heat load variation, 3) Cooling efficiency. overall finding was typologies perform significantly different one another concerning indicators 1 2, but not for indicator 3. It therefore possible to declare typology more efficient than other as this depends construction year considered indicator. indicate further energy-efficiency improvements existing stock are essential realization 4th Generation District Heating technologies Denmark these most likely will lead increased variations need be addressed, instance by enabling larger degree demand-side flexibility systems. large temporal variation buildings’ cooling indicates there potential rethinking e.g. domestic hot water production summer or introduce differentiated billing daily, weekly, maybe seasonal performance. presented can subject several future investigations which discussed paper.
