Development of key energy technologies and their synergies in optimized concepts of standard solutions for energy renovation of houses
The objectives of the project is to break down the barriers for energy renovation of private owned houses in Denmark by: assisting in further development of 4 key energy technologies, exploiting their potential synergies to improve the cost/benefit ratio and demonstrate the optimised concepts in 6 houses. Further the project will develop financing packages in cooperation with local banks. The 4 energy technologies that has been identified as key technologies for energy renovation of single family houses will be further developed in the context of 6 demonstration projects to be selected and carried out in the municipality of Ballerup. The 4 technologies are: external façade insulation, low-energy windows, solar heating and ventilation with heat recovery integrated with heat pumps. The demonstration projects will be monitored to document the obtained energy savings. An existing energy calculation tool - BYG-SOL will be further developed basement calculations and financing packages will be developed. The results will be used to inform the target group - primary house owners - of the energy efficiency renovation potential and the possible solutions. Besides the participating companies will use the results in their own - and common - marketing campaigns
The one house, on Udbakken in Ballerup, is a detached, single-family, yellow-brick house comprising 142 m² - built in 1972, with no basement. No previous energy improvements had been made to the house, which had oil-fired central-heating. The oil tank was to be scrapped, which, together with rising energy prices, led the owners to consider energy-renovation.
The second is a detached family house of 136 m2 with 88 m2 basement, along with a low-ceilinged cellar. The house was built in 1972 and located on Summerbuen in Ballerup. There have not previously been any energy improvements made to the house. However, the front door and the basement door were replaced in the winter of 2008/09. The windows have the original thermal-glazing. It is centrally heated from a private boiler, a relatively new gas-boiler from 2004. It is an integral unit with a 100 liter tank. The system is controlled by an outdoor sensor and thermostats on the radiators. There are uninsulated pipes in the basement and heated floors, with heating kept running in both summer and winter due to damp problems.
