Ecological Footprint of Residential Building in Xining

Abstract

The construction industry has a very significant environmental impact. Based on the theory of ecological footprint, this paper constructs a building life cycle assessment model, which takes Xining residential buildings as the research object, the ecological footprint of a residential building in Xining was calculated by using the advanced ecological footprint model - “provincial hectare method”. The aim is to understand the impact of buildings on the environment, and strive to resolve environmental pollution from the source. The results show that the ecological footprint of the building is 570.32 hm2, which is 1.52 times its ecological carrying capacity. There is an ecological deficit. The ecological deficit should be reduced by improving the sustainable use of materials to promote the sustainable development of the construction industry.
