The multi-facetted design strategy serves as a model for the VELUX Group to inspire its employees and customers of the benefits of healthy design. 

Working Together

As the era of globalization continues, so does the Chinese economy, its expanded construction market, and its growing number of consumers. This dynamic economic environment means that global companies such as the VELUX Group must continue to invest in the well-being of its Chinese employees to sustain innovation and competitiveness. To ensure that this challenge is met, the open floor plan encourages dialogue and greater collaboration and both floors have touchdown zones where employees can gather for informal meetings. A fitness centre, table tennis and a pool table in the basement foster a greater sense of camaraderie among the staff. Furthering the sense of community and belonging, outdoor recreational facilities include football, volleyball, and most significantly: a vegetable garden. 

Referred to as the “Happy Farm”, Managing Director: Christian Olsen delights in the fact that employees “finish their lunch quite quickly and spend the rest of the lunch break tending the gardens.” Collecting the week’s harvest every Friday a mix of corn, peas, chilies, potatoes, watermelon and other products, employees are not only cultivating a garden, but growing an important social dimension to their workplace that employees enthusiastically refer to as a “lifestyle.”

Changing Attitudes, Inspiring People

Since the building became operational, the manager of human resources reports with pride how the rates of sick leave have dropped eight times when compared to the old VELUX offices. And with an expected 10-year payback due to reduced energy costs, the financial and intellectual investments needed to make the new headquarters have been validated. The Langfang office continues to receive approximately 200 visitors every month who include architects, engineers, researchers, professors and most importantly customers and clients who are inspired by what they experience. The constant flow of visitors helps reinforce the building’s significance to the employees, many of whom are not trained in building science but who have been motivated to become ambassadors of healthy indoor environments.

Collaborative Building System

Obtaining the good results of the Langfang Office has required a conscientious effort. “The Langfang climate is very cold and dry. It is a tough climate in which to achieve low energy consumption,” points out Asymeric Novel, consulting engineer during the planning and construction of the building. “The building is an office space. This means that internal heat gains play a major role in defining the heating and cooling loads. In order to reach our targets, the Langfang Office was equipped with a range of energy saving technologies.”

These include:

• A TABS system: An embedded network of water pipes in the mid-plane of all concrete slabs. Combined with a ground source heat pump and an outdoor air unit with variable volume, the TABS system provides pleasant and energy-efficient heating
• A highly-insulated and airtight envelope to limit heat losses in winter
• A CO₂ based control of ventilation
• Extensive use of roof windows and facade windows
• Solar thermal collectors heating domestic water
• Awning blinds that prevent overheating, thereby reducing the need for cooling on hot days
• Heat pump

China’s First Active House Office Building:

In recent years, the VELUX Group has been working closely with the Active House Alliance. The organisation is comprised of academics, researchers, and product manufacturers. Originating out of Europe, the Active House Alliance is an important source for leading-edge sustainable design strategies to improve the design of residential, commercial and office buildings. Comfort, energy and the environment encompass the three key Active House principles, however it is the use of natural daylighting and ventilation with an overarching concern for human comfort that helped guide the VELUX design team to succeed in achieving China’s very first Active House office building.

Achieving the Active House sustainable design principles necessitated achieving a primary and secondary energy consumption rate between of 30-50 kWh/m²/year within a reasonable construction budget.

“What surprises most people is that we can achieve the low energy consumption of 32.14 kWh/m²/year while still having 296 windows in the building,” notes Christian Olsen, Managing Director for the Chinese VELUX operations, adding “This is of course the message we are trying to convey – that windows are important because they are essential in providing a healthy indoor climate.”
