The 105-employee building Energinet.dk in Ballerup near Copenhagen will become a model green building. The compactness of its two-story volume will reduce heat loss (due to the relatively small surface area) and the consumption of building materials. The latter will be environmentally friendly and require a minimum of maintenance; they can also be easily reworked in the future, which, in combination with the free modular plan of both floors of the building, will make it easy to adapt it to new needs.
The first tier of the building will be reserved for meeting rooms and other premises open to outsiders, the second, overhanging the lower one, will be occupied by offices. Both floors will be united by an atrium with north-facing glazed openings in the ceilings, through which daylight will spread throughout the building. At the same time, the triple-glazed facades will be covered with fixed sunscreens to avoid overheating while making the most of natural light. Also, these goals are pursued by the orientation of the building to the north. With the help of the green roof, rainwater will be collected and filtered for use in bathrooms and for irrigation of green spaces.
The energy consumption of the future building will not exceed 48.8 kWh / m2 (with a total area of 4,000 m2). If solar panels, a groundwater cooling system and a heat pump are installed, this number will drop to 35 kWh / m2.
