Energy Consumption in an Old Residential Building Before and After Deep Energy Renovation

AbstractDenmark is participating in IEA EBC Annex 56 “Cost Effective Energy and Carbon Emissions Optimization in Building Renovation”. The housing complex Traneparken has been chosen as a Danish case study for the project. It has been retrofitted with new facades, new windows, additional insulation, mechanical ventilation with heat recovery and a photo-voltaic installation on the roof. The measured energy consumption for heating and domestic hot water before and after renovation was 736 MWh/year and 506 MWh/year respectively. Hereby, the project has demonstrated that the renovation resulted in significant energy savings.This paper presents results from the Danish case study
