The research of the building-integrated solar heat utility in the low-rise residential building Beijing area

Starting after the world energy crisis in 1972 to present concern over global warming, there has been a growing emphasis, which has become a necessary criterion, on integrating energy-efficient strategies in architectural designing to reduce fossil fuel consumption and its associated environmental pollution. In many instances, the development of building design strategies has been primarily dominated by factors such as function, economics, culture, and design trends. It is only recently that the design profession has become interested in quantifying the energy performance or environmental impact of the buildings. In the meantime, the solar heat considered as a kind of the recycled and green energy attracts people’s attention today especially for its utility in the building. For the consumption of the fossil fuel in China is becoming more and more, the utility of the solar heat in the residential buildings which consume a big proportion of the nonrenewable energy can surely decrease the total amount of energy use of the whole country.
As the climate of Beijing has the advantage of the utility of the solar heat, the paper is focused on the “The Utility of the Solar Heat in the Residential Buildings”.
The research is conducted in the following 4 aspects:
1. The utility of the passive solar heat in the design of the building-integrated solar thermal system.
2. The utility of the solar energy-hot water system in the design of the building-integrated solar thermal system.
3. The utility of the solar-wall in the design of the building-integrated solar thermal system.
4. The utility of BIPV system in the design of the building-integrated solar thermal system.
With lots of the data analysis made by software and site surveys and also by using the typology theory, this paper illuminates the view, which concludes the design method for both constructing the new dwellings and the rebuilding of the existing dwellings from the design of the internal space, external space and the skin of the building.
