Design and analysis of a nZEB with IDA ICE.

Abstract: Recently, the environmental policy makers have realized that the building sector is the largest end-use sector with a significant percentage of the environmental load of human activities. What is more, according to official sources, it is necessary a reduction in the building sector of 88-91% of greenhouse gas emissions in order to achieve the goals established by the European Roadmap 2050. That is why laws such as the Directive 2010/31/EU are coming up. That directive says that all member states shall ensure that all new buildings are near zero energy buildings (nZEB) by December 31st, 2019. Therefore, the aim of this master thesis is the design of a nZEB in different climate zones around Spain. All near zero energy buildings designed meet the requirements established by the Spanish technical building code (CTE). In regard to the supply system, a facility is developed by means of IDA ICE consisting of a heat pump connected to an outdoor pool and a ground heat exchanger. The operation of the ground heat exchanger will depend on the temperature of the swimming pool. Finally, it is explained if the swimming pool can work as a heat source for each location studied.
