Low-energy housing with intelligent control of energy use

Low-energy housing with intelligent control of energy use

Housing accounts for a large proportion of the total Danish energy use, which is why stricter requirements for the energy efficiency of homes have been introduced. Through the EUDP project “Bolig 2020”, our researchers have contributed to the development of a low-energy detached house that meets both energy requirements and provides a healthy indoor climate. In order to meet energy requirements, the house has its own solar panel system, and the researchers aim to develop solutions that can maximize the interaction between the building and our energy supply, including the use of power from the home's own photovoltaic system.

- Energy use in the home must be even more flexible, intelligent and efficient. Therefore, we need to improve control and automation of the house’s energy system so the synergies between energy production, storage and use are utilised to their maximum. For example, the system – and not the consumer – should ensure that heating is turned off in periods with peak use of domestics hot water, that heat is stored in building constructions prior to cloudy periods and that the electric car doesn’t charge between 5 pm and 10 pm as long as the car is fully charged the next morning. We must find intelligent solutions to manage this, says Rasmus Lund Jensen, associate professor at the Department of the Built Environment.
