Carbon emission calculation method based on entire life cycle of building

Abstract

The invention provides a carbon emission calculation method based on the entire life cycle of a building and relates to the technical field of carbon emission calculation. According to the features of carbon emission, carbon emission calculation is divided into four stages of building material production, building construction, operation maintenance and waste dismantlement. The method includes the steps that a carbon dioxide intensity value of building material production is determined; carbon emission coefficients in the material transportation and construction processes in the building construction stage are determined; carbon emission coefficients of consumed energy in the operation maintenance stage are determined; carbon emission coefficients of the construction technology and waste transportation in the waste dismantlement stage are determined; the total carbon emission amount of the building is calculated through collection; the unit area index and the per capita index are calculated, the indexes of the total carbon emission amount, the unit area carbon emission amount and the per capita carbon emission amount of the building in the entire life cycle are acquired, the carbon emission standard which the low-carbon building can reach is checked, assessment and affirmation are conducted, effective measures such as design, construction and operation are taken in each stage of the building, the carbon emission of the building is reduced, and the low-carbon level of the building is improved.

Description

technical field [0001] The invention relates to the technical field of carbon emission calculation, and specifically refers to the calculation of carbon emission in the whole life cycle of a building. Background technique [0002] In recent years, following energy-saving buildings and green buildings, low-carbon buildings (LCB) have become another building model, which requires the evaluation of buildings through the calculation of carbon emissions. There is currently no clear definition of low-carbon buildings, mainly because there is no global consensus on the quantification of low-carbon emissions. The design guidelines put forward by the London government believe that compared with the prevailing building codes at that time, the low carbon emission of buildings should reduce the CO2 formed by energy use in a year. 2 Emissions are reduced by 50%. British scholar Stern believes that this amount of emission reduction should be equal to that of general building CO 2 80% of...
