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.”
