Research On Carbon Calculative Formulas Of The Life Cycle Of A Natatorium In Hot Summer And Warm Winter Zone

Global warming threatens the survival of human race gradually. Largely using fossil energy has leaded some natural disasters in worldwide, such as sea level rising and glaciers melt. In order to maintain human sustainable development, reducing CO2 emission globally is emergent. Architecture industry has a huge promoting space in CO2 emission reduction comparing with industry and transportation fields. The reduction of CO2 emissions is based on accurately and appropriately evaluating CO2 emissions in architecture industry.Firstly, this article has analyzed stage division of life cycle management in construction and the composition of CO2 emission in different stages. Then, come up with calculation matrix for natatorium in hot summer and warm winter zone. In order to specific calculate the changes of CO2 emissions after use energy-saving measure, calculation matrix is divided into four accounting levels on vertical axis, including unchanged measure, changed measure, energy-saving measure linking with the main building and importing renewable energy sources measure. Horizontal axis is classified as construction stage, operation stage and disassembly stage. A 4×3 order calculation matrix can be developed.Secondly, this paper has bulid calculation formulas of natatorium in life cycle management, which mimic the statistical proposal that proposed by Intergovernmental Panel on Climate Change when calculate CO2 emissions. The statistical proposal is that consumption multiply emission factor. These calculation formulas mainly include materials product, transportation of materials, mechanical applying and water/ electricity consumption, CO2 emissions factors come from literatures, while the consumption of materials/energies can be obtained from calculation formulas provided by this article.Third, this paper mirror CO2 emissions of life cycle from CASBEE green assessment system. Then, Low Carbon Assessment System had been promoted.Finally, a new natatorium of college in Guangzhou is used as case study. The results show that during the life cycle of this natatorium(55 years), CO2 emissions is 80.28 kg/y?m2,The unit time of CO2 emissions intensity in construction phase is highset(280 kg/m2), then is the intensity of operation stage(80 kg/m2), so construction and operation phases should be pay attention. In construction, restoration and disassembly phases, a method that calculating materials product as main item and mechanical applying as a complement should be taken. In operation phase, the CO2 emissions of air-source heat pump and air-condition highly reach to 90%. After taking energy-saving measures, the CO2 emissions reduce apparently.
