摘要
Abstract
Taking a library in Gansu Province as an example,the energy consumption(electricity consumption)of buildings with energy-saving rate of 65％and 72％and zero-energy consumption was simu-lated by Energyplus software,and the carbon emissions throughout the whole lifecycle of three energy-saving buildings were compared.Buildings with energy effi-ciency rate of 65％have the highest building energy consumption,buildings with energy efficiency rate of 72％have the moderate building energy consumption,and buildings with zero-energy consumption have the lowest building energy consumption.Among the carbon emissions throughout the whole lifecycle of buildings,buildings with energy efficiency rate of 65％and 72％have the highest proportion of carbon emissions during their operation,and buildings with zero-energy con-sumption achieve zero carbon emissions during their operation by utilizing renewable energy(photovoltaic power generation and wind power generation).Build-ings with zero-energy consumption have the lowest car-bon emissions throughout their whole lifecycle,account-ing for only 9.89％and 10.69％of buildings with en-ergy efficiency rate of 65％and 72％,respectively.Carbon emissions mainly occur in the production stage of building materials,construction and demolition sta-ges of buildings.关键词
