Task Group EnergyA feasibility study was conducted together with Dacheng Co. for a 173-metre-high high-rise building, the Dacheng International Tower B, which would be the second-highest building in Urumqi. The RECAST Urumqi team has analysed the possibility of building a true passive house and concluded with an intelligent building design this can be achieved. The design includes 15 cm insulation on external walls, passive house windows, and a high quality heat recovery system. Simultaneously, the size of the window area and the external shading coefficient in summer need to be optimised in order to keep the cooling demand as low as possible.
