BOLIG+ An Energy Neutral Multifamily Building
Abstract
BOLIG+ is a Danish concept for energy neutral houses based on five dogmas: 1) energy neutral incl. household energy, 2) intelligent and user-friendly, 3) flexible in daily use and over time, 4) good and healthy indoor climate and 5) high architectural quality and adaption to local context. The first BOLIG+ building will be a 10/6 storey multifamily building with 60 apartments and a total floor area of 7000 m2. Five teams were asked to submit a proposal to a project contest. The five teams were found in a pre-selection among 44 interested teams. The winning team, TEAM+1, was appointed in September 2009. The building will be build on normal commercial conditions which made the task of designing the building rather difficult as the location wasn’t well suited for solar energy and the price of district heating is very low in the area. However, the five teams came up with five projects which easily may be transferred to other locations. The winning team utilized a low energy prefab system for the building envelope in combination with energy savings of the household energy demand plus a heat pump, PV and PV/T collectors. It is the aim that the construction of the building will start during 2011. Due to the prefab building system the construction time is foreseen to be less than one year.
