Velta

Balanced Office Building

The project

The Balanced Office Building in Aachen saves 94% energy for cooling against conventional cooling methods and 60% energy for lighting through its daylight control. Low operating costs, minimal energy consumption and limited expenditure for day-to-day running – these are the expectations that both property developers and users place on modern day buildings. Balanced Office Building (BOB) in Aachen provides the successful response.

The solution

Key focuses of the innovative concept lie not only in the insulation, ventilation and lighting, but also in heating and cooling. velta was able to offer a solution in the concrete core activation in the form of the velta contec, which provides comfort, flexibility and effective energy saving.

The benefits

One of the most important aspects of BOB is its energy concept: the heat losses are dramatically minimized by the building fabrics, an external envelope with excellent sealing, the innovative use of geothermal energy, concrete core activation and lower ventilation rates.

With its 1500m² of useful area:

• BOB heat demand equates the demand of a normal, single family house.
• Saves 94% energy for cooling against conventional cooling methods.
• Daylight depending light control
• Rainwater management
