After finishing the new built passive house quanfa 50,  a fan of the passive house building technology provided us with the site to realize a passive house as a showhouse. The idea was to realize it by sponsorship of the different brands, which they were willing to support enthusiastically. But the compound recalled the permission to build individual designed houses.

The house design is still used as a case study with all calculations for passive house energy saving standard, energy consumption not more than 15kwh/sqm/a, with Beijing climate. It was designed on the narrow site as a long bar with a nice entrance hall, big enough to serve as a home office, service and sleeping rooms in the first floor, and the living space with a big terrace in the second floor.
