VELUX Langfang Office is the headquarters of VELUX China. Located in the Hebei province, around 45 kilometers from Beijing, the building houses management, marketing and the technical department and sales division.
The two-storey building, with slopping walls and in the shape of a pyramid with cut-out top, is the workplace of 54 employees. They enjoy a range of facilities on the company site, which is shared with the nearby VELUX window factory.
The office was completed in June 2013. It has significantly lower energy consumption than standard Chinese office building.
The new Velux office in Langfang has been designed and built to meet several objectives:
· A real estate objective:
- Consolidate the operations on a single site (2 sites before)
- Being a showcase of the Velux products
- Show the commitment of the Danish company to sustainability and low carbon corporate policy.
· An economical objective:
- The operation must be neutral: the construction and operation costs are paid back by the saved rent
- Controlled construction cost in order to replicate the model in the Chinese market.
· An environmental objective:
- Reach a target value of 40 KWh/m²/year (excluding office equipment), and 55 kWh/m²/year (including office equipment) of final energy consumption (2020 Danish thermal regulations)
- Having a great indoor environmental quality: The VELUX Langfang Office aims to show that we can improve working conditions with minimum environmental impact
