Study on the Design Strategies of Residential Buildings for Adapting Heat Stress and Indoor Air Quality under Climate Change

In response to the extreme weather events cause by climate change, residential buildings should develop adaptation strategies, especially design of building envelope. Building envelope influences indoor environmental quality such as thermal comfort, ventilation, lighting, as well as building energy consumption. However, most studies only focus on the adjustment of a single factor, but neglect the possible interaction between factors. Some research indicated that concentration of outdoor pollutants may increase the healthy risk of natural ventilation, thus comprehensive effect need to be considered in the design of building envelope. However, comparing with the specification of building construction in the building code for energy efficiency, very less regulation are based on the science studied of health risk. In this research project, we will first obtain the hourly weather data of 2030 and 2050, based on the Weather Research Forecasting nested with ECHAM5/MPIOM model of the IPCC AR4, A1B scenario. Simulation of indoor environmental quality (temperature, illuminance, PM2.5) and energy consumption will carry out by using EnergyPlus, a building performance analysis tool provide by Department of Energy, US. Construction parameters including thermal insulation, shading, glazing and the style of opening will be discuss in the simulation, and the evaluation criteria of health risk will be provided by the other sub-project. The expected results of the project are the proposed revisions to the Residential Policy (mainly the Technical Code for Buildings), which is how the design, lighting, ventilation, air quality and energy efficiency of the residential design strategies will be taken into account.
