摘要
随着中国于2021年承诺的2030年“碳达峰”与2060年“碳中和”的目标日益接近,减碳已经成为了我国的重中之重。截止2019年,建筑全生命周期在我国碳排放总占比接近51.3%,若建筑节能标准不提升,那么预计2040年才能达到碳达峰的目标。所以,北京住宅建筑节能在2022年进一步提升了标准,在2015年居住节能标准的基础上,提升了30%,形成低能耗住宅。同时,国标也完善了超低能耗住宅的行业标准,形成可以进一步节约能耗的超低能耗住宅。低能耗住宅与超低能耗住宅建筑将成为未来低碳发展的重中之重。按照两种不同节能标准所建造的住宅在全建筑全生命周期中所产生的碳排放量也将成为行业关注的重点。
Carbon reduction has become a top priority for China as the country moves closer to achieving"peak carbon"by 2030 by 2021 and"carbon neutrality"by 2060.By 2019,the total carbon emissions of the whole life cycle of buildings accounted for nearly 51.3%of China's total carbon emissions.If the energy efficiency standards of buildings are not improved,it is expected to reach the target of carbon peak in 2040.Therefore,Beijing residential building energy conservation standards in 2022,on the basis of 2015 residential energy conservation standards,increased by 30%,forming low energy consumption housing.At the same time,the national standard has also improved the industry standard of ultra-low energy consumption housing,forming ultra-low energy consumption housing that can further save energy.Low energy consumption residential buildings and ultra-low energy consumption residential buildings will become the top priority of low-carbon development in the future.The industry will also pay attention to the carbon emissions generated by homes built to the two different energy efficiency standards over the entire life cycle of the building.
