07■■■■■■■■High insulaIn this project, we will construct a system for evaluating and visualizing CO₂ emissions related to non-structural components̶an area in which no research and development progress has been made so far̶taking life stages into consideration, in order to create a society oriented toward environmentally friendly construction. We will also promote research and development of high-functionality materials, including exterior materials, interior materials, entrance components, and foundation materials, as well as construction methods that help to reduce CO₂ emissions during manufacturing and construction.In order to reduce the burden of buildings on the environment at a time when efforts to eliminate carbon are increasing throughout society, it is crucial to establish an academic foundation for achieving environmentally friendly construction at a high level and to develop a comprehensive platform for encouraging the implementation of those goals in society. In particular, non-structural components for approximately 20% of the CO₂ emitted as embodied carbon during the construction. However, despite individual studies and societal attempts from an environmental conservation perspective, there has been little holistic attempt to optimize the overall environmental impact of buildings.In order to reduce the environmental impact of non-structural components, we need to consider whole life carbon̶the total amount of CO₂ emissions produced during a building's life cycle, including embodied carbon as well as operational carbon, which is the amount of CO₂ emitted during the operational stage of a building. However, at present, there is no established method for assessing whole life carbon. Another issue is that in the case of non-structural materials, unlike structural materials, there has not been adequate preparation of the basic information that would be indispensable for making precise calculations of embodied carbon, taking into account the effect of differences in material processing treatments on environmental impact, the effects of reducing environmental impact through the use of recycled materials, and other such factors.In this project, we will develop a system for evaluating and visualizing the CO₂ emissions of non-structural components for each life stage, and we will promote research and development of materials and construction methods that achieve a high degree of compatibility between environmental performance and functionality with regard to exterior materials, interior materials, entrance components, and foundation materials̶items that have a high level of impact on whole life carbon. We will also contribute to nature-positivity, encouraging research and development directed toward high-functionality and Longer service lifehigh-performance interior and exterior building materials that also promotes resource conservation and recycling.By promoting this industry-academia collaboration project as a comprehensive initiative based on open innovation, the project's members intend to create pioneering examples in a Wood utilizationwide range of boundary regions and lead the way in environmental conservation efforts within the construction industry.This project is an Open Innovation Project conducted by Tokyo University of Science and Shimizu Corporation.■■■■■■■■High insulationExamples of efforts aimed at achieving environmentally friendly constructionIndustrial and Systems Engineering■■■■■■■■Actively using woodAn Open Innovation Projectinvolving approximately 25 peopleArchitecture and Global Fire Science Architecture (materials)(fire protection and resistance)Architecture (environment)and Technology Pure and Applied ChemistryResource conservationConserving materials and streamlining High insulationResource recyclingCircular economystructural engineering methodsDeveloping surface finishing to ensure freedom of designtechniques exterior materialsEmbodying energy-saving Using exterior materials that contribute to energy conservationby reducing the energy required for heating and cooling during the operational stageProactively utilizing recycledaluminum and steelEncouraging the use of woodResource conservationConserving materials and streamlining High insulationResource recyclingCircular economyWood utilizationstructural engineering methodsDeveloping surface finishing to ensure freedom of designtechniques Embodying energy-saving exterior materialsUsing exterior materials that contribute to energy conservationby reducing the energy required for heating and cooling during the operational stageProactively utilizing recycledaluminum and steel■■■■■■■■■Encouraging the use of woodEnsuring high durabilityReducing deterioration and of aging through structural controlling the effectsengineering methodsImproving the performance of ■■■■■■■■■■■■■foundation materials and insulation materialsMaking improvements that encourage the utilization of Using interior materials that contribute to energy conservation■■■■■■■■■■■■■by reducing the energy required for ■■■■■■■■■■■heating and cooling during the woodoperational stageEnsuring high durabilityReducing deterioration and of aging through structural controlling the effectsengineering methodsEncouraging the use of woodMaking improvements that encourage the utilization of woodLonger service lifeWood utilization■■■■■■■■Encouraging the uImproving the perf■■■■■■■■■foundation mateinsulation maUsing interior matcontribute to energy ■■■■■■■■by reducing the energ■■■■■■■heating and coolingoperational s■■■■■■Actively usingWood utilizResearch ＆ Development Platform of Functional Green Building MaterialsAchieving Environmentally Friendly Construction Through Research and Development of High-Functionality Materials and Construction Methods That Help to Reduce CO₂ Emissions②
