Vác zero energy building
The building was designed in the suburban part of Vac, to replace a demolished building. The external wall structure of the building is very simple, made of 44-cm-thick hollow ceramic wall blocks that have a very good insulation capacity. During the design of the building, in addition to the adaptation to the surrounding buildings and to being a corner building, it was an important aspect that the main rooms of the building should be oriented towards the favourable southern orientation. In accordance with the customer, it was possible to design a gable roof form, which allows the aesthetic installation of a significant amount of solar panels on the South. According to the calculations, beyond the total energy demand of the building, the installed solar panels are sufficient to charge an electric car (for 10,000 km/year).
Adopted strategies
- Sun exposure and internal spatial organization (bioclimatic aspects)
An important aspect during the design of the building was that the main rooms of the building should be located towards the favourable southern orientation, allowing a significant passive solar energy utilization.
- Building services systems and renewable energy utilization
The building is heated and cooled by a cost-effective ground-to-air heat pump system with shallow boreholes. Solar panels were placed on the south-facing roof surface.
- Energy class achieved (eg level A, B) or category improvement achieved (in case of renovation)
Calculated energy demand of the building, taking into account the installation of the solar panels for the entire roof area (12 kW): - 110 kWh/m2
