Abstract

The building energy consumption accounts for a significant proportion in the total energy consumption. In the paper, we provided a quantitative evaluation method of house sustainability based on ecological footprint theory. To compare the ecological footprint of different materials houses in the northern urban and rural areas of China with the ecological footprint in the world, four models of different residences with different materials were built to calculate the ecological footprints in whole life cycle. The results show that if we could reduce the ecological footprint of rural houses, the new energy-saving technologies and low-carbon supply systems will be applied in construction and materials with less ecological footprint will be used. Architects could search for much more design methods to reduce the ecological footprint of rural house in whole life cycle.
