Abstract

According to the characteristics of economic and energy transformation and step development in the developmentprocess of Shanxi Comprehensive reform area， it is a new trend of regional distributed energy supply in the future toreduce the energy demand of individual buildings and increase the energy supply vitality of the whole region. Combinedwith the development needs of prefabricated and green construction， a “three-in-one” comprehensive solution of nearzeroenergy consumption and multi-objectives was proposed， achieving a carbon reduction of 61.78% in buildings.

面對(duì)全球氣候變化的嚴(yán)峻形勢(shì)，發(fā)達(dá)國(guó)家紛紛制定碳中和中長(zhǎng)期發(fā)展目標(biāo)，2020 年9月22 日我國(guó)在第七十五屆聯(lián)合國(guó)大會(huì)上提出“30·60”碳達(dá)峰碳中和目標(biāo)后，建筑領(lǐng)域是我國(guó)實(shí)現(xiàn)雙碳目標(biāo)的重要戰(zhàn)場(chǎng)，隨著城鎮(zhèn)化建設(shè)的不斷推進(jìn)，區(qū)域能源供給面臨低碳轉(zhuǎn)型，而新型能源供給方式對(duì)建筑單體提升能源利用效率和接納能力提出了更高要求[1]。（剩余8034字）
