格罗宁根建筑是一座具有100多年历史的老建筑,对其进行翻修需要保持原有结构以及立面不受破坏的同时,附加修建2个双层的住宅。西狮家用24h,并在仅有5m宽的街道上完成了施工。该翻新工程将原有建筑外墙的保温热阻值提高到15m~2·K/W(U值为0.06W/(m~2·K)),并实现了真正意义上的零能耗建筑。 The Groningen Building is an old building with a history of more than 100 years. To renovate the Groningen Building requires maintaining the original structure and the facade intact, an additional two double-storeyed houses are to be built. West lion home for 24h, and only 5m wide streets completed the construction. The renovation project will increase the thermal insulation resistance of the original building’s external wall to 15m ~ 2 · K / W (U value of 0.06W / (m ~ 2 · K)) and achieve a truly energy-efficient building .
