Energy Design Summer

In summer the most important challenge for the energy design of office buildings is to keep the temperature in all rooms at a comfortable level.
The shades are a very effective way to reduce thermal loads. They are integrated into the 3-layerd window glazings. This way they are perfectly wind proof and can be used at all times.

If nevertheless temperatures rise cold water is being pumped through a system of concrete core activation within the ceilings. The water absorbs the heat and takes it to twelve borehole ducts of 70 meters depth each. This cooling system is also used for the ventilation of the conference rooms.

Energy Design Winter

In winter the high quality building envelope ensures good thermal comfort. All walls are insulated with 16cm of mineral wool. The windows have wood-aluminum frames and highly insulated glazings. They are fastened to the walls with air tight connections.
This avoids low temperatures on inside surfaces and reduces the risk of draught.

The building is supplied with district heating. It is used for the air handling units in the conference rooms and for the convector heaters in the offices. The borehole ducts are also used in winter to preheat the supply air for the conference rooms.

Office Concept

The offices are part of the integrated concept for energy efficiency and user comfort:

- highly insulated walls
- windows with air tight Fconnections
- individually controlled heating
- concrete core activation
- no suspended ceilings
- window integrated shades
- suspended lamps with Fdirect/indirect lighting
- acoustic panels

The intelligent combination of the high quality envelope and efficient systems reduce the energy demand of the New House of the Region to 50% below the mandatory code requirement.
