近零碳集合住宅減碳效益之研究

Research on Carbon Reduction Benefits of Nearly-Zero-Carbon Residential Building

國家發展委員會於2022年3月公布臺灣2050淨零排放路徑及策略，2030年公有建築物100%達建築能效1級或近零碳建築，內政部建築研究所於2022年公告住宅類建築專用的新建住宅能效評估系統R-BERS手冊，由於住宅建築能效標示制度須包括大規模社會住宅，以落實有效的社會住宅節能減碳政策，然此評估不同於歐美國家以簡單的獨棟住宅或小規模多戶連棟住宅為能效評估對象而面臨挑戰，故本研究選定4個設計規劃階段社會住宅與11個不同案例設計策略來檢驗減碳效益與評估系統敏感度，提供既有需求說明書可達成淨零住宅之建議，以確保大型集合住宅執行住宅能效評估具信賴度。

The National Development Council announced“Taiwan’s Pathway to Net-Zero Emissions in 2050”in March 2022. In 2030, 100% of public buildings will reach building energy efficiency level 1 or become near zero-carbon buildings. The Ministry of the Interior’s Architecture and Building Research Institute drafted R-BERS in 2022, an energy-efficiency evaluation system specifically for new residential buildings, as the residential building energy-efficiency labeling system must include large-scale social housing to realize effective social housing energy-conservation and carbon-reduction policies.
Because the object of this assessment is different from the single-family housing or multi-family townhouses used in such energy-efficiency evaluations in the US and European countries, this study thus selected 4 social housing buildings in the design planning stage and 11 different case design strategies to test the carbon reduction benefits and the sensitivity of the evaluation system. Suggestions for zero-carbon housing are proposed to ensure the reliability of residential energy efficiency assessments for large-scale collective housing.
