摘要：China has published “Green Building Action Plan”. Developing green building is necessary to shift urbanizationmode in China. “China Evaluation Standard for Green Building” has set per capita residential land index asthe prerequisite for residential buildings. Absolutely, per capita residential land index depends deeply on percapita floor space of residential building. In China, national and local “Evaluation Standard for Green Building”raise demands of per capita residential land index. According to those requirements, this paper conducted acase study and calculated changes of residential construction land area with different set values of percapita floor space of residential building. This paper also built a residential building model and utilizedsimulation to analyse annual building energy consumption. Results indicate that per capita floor space ofresidential building decreases accordingly while per capita residential land index reduces, and every 5%increase in per capita residential land index translates into about 7 percent decrease in construction landarea. On the aspect of energy consumption, per capita floor space of residential building reduces 17.2%only. While annual energy consumption reduces 17.45% in return. It is concluded that controlling per capitafloor space of residential building is important to maintain the energy-saving and land-saving properties ofgreen building.
