Denmark is participating in the International Energy Agency -- Energy in Buildings and Communities (IEA-EBC) Annex 61, titled Development and Demonstration of Concepts for Deep Energy Retrofit in Government/Public Buildings. The purpose of IEA-EBC Annex 61 is to improve the decisionmaking 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 seven buildings in total -- two schools and five kindergartens/institutions -- that will undergo deep energy renovation over the next fewyears.The seven buildings are being energy-renovated and monitored with support from the European Union- CONCERTO initiative as part of the project titled Cost-Effective Low-Energy Advanced Sustainable Solutions -- Class1 (2014). The buildings are very different and therefore the energy renovations vary from building to building. The gross list of energy-saving measures that have been 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 using building energy management systems. This paper presents preliminary results of the analysis and monitoring of energy consumption and indoor climate in one public school before and after deep energy renovation.
