Achieving nearly zero energy buildings in Cyprus, through building performance simulations, based on the use of innovative energy technologies

This paper presents the methodology and initial findings from modelling and simulating advanced energy conservation and generation technologies in two case study buildings in the area of Peyia, Cyprus. The simulations were performed through free-running and thermostatically-controlled conditions by means of Design Builder software, in order to achieve the nearly zero energy (NZE) target. The specific objectives are both a reduction of the net regulated energy to an average of 0-20 kWh/m2 per year, as well as a generation of at least 50 kWh/m2 per year in each building. The findings of the study are that the nearly zero energy target is achievable if a majority of the energy used in the buildings comes from renewable energy technologies and if the regulated loads of the buildings are reduced through the use of energy conservation technologies.
