Monitoring Results of the Energy Consumption Behaviour of Two Highly Solar-Powered Apartment Buildings
Abstract
The CO2-neutral self-supply of heat and electric energy is an important objective for new buildings. Two new apartment buildings (7 units each) built in 2018 according to the solar house concept will achieve solar fraction of up to 77% electrically and 65% thermally through solar thermal and photovoltaic systems and thermal and electrical storages. The tenants receive all energy services, independent of consumption, financed by a flat-rate rent. Within this article, the first results of one year monitoring with the effects of the user’s behaviour on the energy balance of the apartments and building is analyzed.
