Thermal Performance of a New Ventilated Concrete Envelope
Traditional building envelope is static and cannot regulate its physical characteristics according to outdoor climate. A new ventilated concrete envelope proposed in this paper consists of insulation layer, airflow layer and thermal storage layer. In order to evaluate and optimize the thermal performance of this new envelope, the flow and heat transfer model was established based on the heat balance method and a demonstration house was tested to verify the heat transfer model. On this basis, the influences of insulation layer thickness, air layer thickness, air supply speed and heat storage layer thickness on thermal performance of the envelope were considered, and the sensitivity analysis was conducted. It was found that the air layer thickness and air supply speed had big influence on the performance of the envelope in summer, while the heat storage layer thickness and insulation layer thickness had big influence in winter.
