本研究では、断熱工法の異なる小規模住宅モデルのLCCO2を比較し、CO2削減に最も効果的な工法を検討した。断熱パネルを用いた工法が最もLCCO2削減に有効であり、解体後に分離できない工法はリサイクル資源として利用できない点で不利であった。
English
This study compares the life cycle CO2 (LCCO2) of small-scale housing models with different insulation construction methods, focusing on both embodied and operational carbon. The construction method using insulation panels was most effective in reducing LCCO2, while methods that prevent material separation after demolition were disadvantaged due to inability to be recycled.

📄 Abstract（原文）
Regarding LCCO2, which is the total amount of CO2 emissions resulting from the procurement of building materials to their disposal, discussions are underway not only on operational carbon, which is generated during the operation of a building, but also on embodied carbon, which is generated during the manufacturing, transportation, construction, renovation, and disposal of materials. Regarding operational carbon, simulation methods and standards for energy use have been established, and their evaluation is progressing with the aim of promoting ZEH and ZEB. However, regarding embodied carbon, it is necessary to understand the various actual situations at the stages of a building’s life cycle, and the establishment of estimation methods and reduction methods are under consideration. Regarding embodied carbon, attention has been focused on the material consumption of building, but it is also important to consider a method of calculation from detailed items assuming actual construction, such as building materials and construction activities associated with construction and demolition. In particular, it is possible to aim to reduce embodied carbon by using different construction methods even though the same materials are used, and this time we focused on the differences in construction methods. In this study, we compared the LCCO2 of small-scale housing models with different insulation construction methods to examine the construction method that is most effective in reducing CO2 emissions. In addition, we focused on insulation materials to improve the insulation performance of buildings, thereby reducing energy consumption for heating and cooling, and calculated the LCCO2 reduction effect of buildings. The construction method using insulation panels was the most effective in reducing LCCO2. In addition, construction methods that do not allow separation after the building is demolished were at a disadvantage because they could not be used as recycled resources.
