Both design and technical solutions are focused on sustainable initiatives. The goal is to reduce energy consumption - both in the construction phase and the operational phase.
- The building meets the Danish class 2015 low energy requirements:
- Thermal loss has been reduced because the compact form of the building envelope offers a relatively small surface area.
- Natural shadow effects are achieved by the size of the floors and their relative positions.
- In the winter months, the sun's rays will strike the facades of the building; in the summer months, when the sun angles are high, the lower floors will be shaded by the roof plate.
- There are sunscreens on the skylight windows and solar shades on all other glass facades. When there is too much sunlight, motorised solar shades are activated to reduce the influx of light.
Solar panel array
- A 2,432 m2 solar panel array has been set up on the roof of the building. A glint and glare assessment has been made to measure possible effects on the surrounding neighbourhood.
- Seawater is used to cool the building - both for ceiling cooling panels and for ventilation - thus considerably reducing energy consumption for cooling purposes.
- Both inside and outside, the emphasis has been on reducing energy consumption as much as possible, including the use of LED lamps.
- The use of motion and daylight sensors reduces energy consumption when the influx of daylight increases.
- Lights are automatically turned off when areas have not been in use for a determined period of time.
Automated underground parking facility
- Lights are only on when people are working there, minimising energy consumption for lighting.
- The underground parking facility is heated by reusing air vented from the building above.
- Less fuel is used when moving vehicles in and out of the facility.
- Only a little ventilation is needed underground as there are no vehicles driving around down there.
- Vehicles are much less exposed to vandalism and owners feel more secure (social sustainability).
Indoor climate: Acoustics and sound
- The building lives up to the standard reverberation time, so that it feels comfortable to be there despite many large, high spaces.
- Noise level requirements for horizontal and vertical room partitions have been met, so that interference from other activities in the building has been reduced to a minimum.
- Permanent hearing loop systems have been installed in various parts of the building.
Plumbing, ventilation and cooling
- The insulating power of the building and the energy performance of its installations have been optimised.
- The building's thermal indoor climate has been analysed with regard to the maximum permitted temperature limit and possible inconvenience caused by light from the skylights.
- Variable air volume systems related to the temperature of the room and the CO2 content of the air have been installed in areas with large variations in the numbers of people using them.
- All ventilation systems are programmed for night cooling, using cooler nighttime air to reduce the need for extra mechanical cooling in the building.
- There is remote monitoring of water and heating meters to check consumption.
- Touchless taps and hand dryers have been installed.
Light and solar control
- Cladding glass with a low thermal transmission factor has been used.
- Skylight glazing has been chosen on the basis of window energy ratings.
- Internal sun blinds have been fitted.
- All monitoring systems in the building are hooked up to a comprehensive Building Automation System (BAS), which can control most of the building's mechanical and electrical equipment.
Choice of materials
- Robust and environmentally friendly materials have been used.
- The use of dangerous materials has been avoided.
- Natural, recyclable construction materials have been used: concrete, glass and steel.
- The materials used in the building are mostly concrete, steel, glass and aluminium.
- Technical installations have been fitted in such a way that they can be replaced by improved versions in the future.
