Load management of nZEB – an important element for future energy supply and implementation of renewable energy sources


This article describes two projects in nZEB housing including heat pumps, where the aim was to create and operate buildings which meet future demands on energy efficiency and living comfort. The guiding principle for the development and operation of these buildings is that an optimal use of solar energy should be implemented. This results in a higher energy gain than the buildings’ needs. Both projects use control strategies to increase the use of photovoltaic electric power and reduce grid consumption. In order to reach this target the energy concepts make use of flexible components, i.e., heat pumps in combination with thermal and electrical storages. Thus, a high share of solar electricity usage can be achieved.
