Results
The project was carried out in four phases: the design and precompetition period, the competition period (17th-28th of September 2012), the measurements in Bjerringbro from 26th of September 2013 to 1st of October 2014, and the investigations of the improvement possibilities in the building and HVAC system design.
The experiences and the results revealed that it is possible to build plus-energy houses that are aesthetically appealing, energy efficient, environmentally friendly and have a healthy and comfortable indoor environment. Though, this requires careful and detailed design, operation, and good craftsmanship (air-tightness, building envelope, lowered thermal bridges, etc.). Even though it might be possible to improve the energy performance of the house with some changes after the construction, this is not the optimal situation. This house diverged from the ideal situation, due to the high heating and cooling demand. It should be noted that with less heating and cooling demand, it would be possible to achieve plus-energy targets with less area of active components (e.g. photovoltaic/thermal panels).
