Energy Use and Indoor Climate in Two Schools Before and After Deep Energy Renovation

Denmark is participating in IEA ECBCS Annex 61 “Development and demonstration of concepts for deep energy retrofit in government/public buildings”. The purpose of the Annex is to improve the decision-making process to achieve deep energy retrofits of government/public buildings, starting with the determination of working bundles of technologies and corresponding business models using combined public and private funding.Denmark will contribute to the project with 7 buildings in total, i.e. 2 schools and 5 kinder-gartens¬/institutions, which will undergo deep energy renovation over the next few years. The 7 buildings are being energy renovated and monitored with support from the EU-CONCERTO initiative as part of the project “Cost-effective Low-energy Advanced Sustainable So1utions – Class1”.The buildings are very different and therefore the energy renovations to take place will also vary from building to building. The gross list of energy saving measures that will be implemented includes: Improved insulation of roof and external walls, new low-energy windows and shading systems, new or renewed ventilation systems with heat recovery, low energy lighting, water saving measures, improved insulation of piping and improved control (Building Energy Management Systems – BEMS).This paper presents preliminary results of analysis and monitoring of energy use and indoor climate in the two public schools before and after deep energy renovation
