|Description||The new office building of Energinet.dk in Ballerup is a low-energy building. The lowest energy class possible has been achieved exclusively by means of optimising the design and geometry.|
The building has an annual energy consumption of only 47,7 kWh/m2. Incorporating solar panels, ground water cooling and heat pumps in the project would further reduce the annual energy consumption to only 35 kWh/m2.
The new office building of Energinet.dk covers 4,000 m2. The simple architectural design has resulted in a flexible and easily comprehensible building consisting of three elements: meeting facilities on the ground floor, a uniting atrium and workstations on the top floor, which floats above the sloping landscape. The atrium is identity-creating, open and active.
A significant part of the environmental objective has been to ensure a high degree of flexibility. The open layout of the first floor as well as the light walls and simple, reusable elements will make it easy and problem-free to change the interior layout in the future.
Henning Larsen Architects has designed a low-energy building solely by means of optimising the design and an geometry - resulting in an office building in the lowest energy class possible. The building has an energy consumption of only 47,7 kWh/m2 a year. Incorporating solar panels, ground water cooling and heat pumps in the project would further reduce the annual energy consumption to only 35 kWh/m2. The building meets the requirements for low-energy class 1 according to Danish building regulations without the use of energy producing technologies.
The building has a green roof serving several sustainable purposes: It reduces the load on the public sewage system by means of slow percolation and evaporation. In addition, the collected rainwater is used for flushing the toilets and watering the garden, which contributes to reducing the overall energy consumption for cooling.
