| Activities |
The Building Services Commissioning Association (BSCA), a non-profit organization, leverages its advanced technology and a wealth of experience in air conditioners and other building services to engage in the following commissioning activities to serve the public. -Improve the quality of building systems, their energy performance, and environmental performance-Educate and guide the next generation of professionals in the area of building commissioning. -Conduct research related to commissioning and engage in educational activities and initiatives to promote commissioning. -Develop and conduct advanced commissioning projects to standardize and disseminate commissioning best practices. -Provide advice and support to commissioning projects. -Through engaging in the above activities, promote public interests such as environmental conservation, social education, and sound community planning. |
Message from the Chairman
On February 18, 2025, both the Plan for Global Warming Countermeasures and the 7th Strategic Energy Plan were approved by the Cabinet. These are key medium- to long-term policy documents guiding Japan’s efforts toward decarbonization, energy transition, and climate change mitigation.
The Global Warming Countermeasures Plan sets new targets of a 60% reduction in greenhouse gas emissions by FY2035 and a 73% reduction by FY2040 compared to FY2013 levels, outlining a linear pathway toward achieving net zero by 2050. These targets have been submitted to the United Nations Framework Convention on Climate Change (UNFCCC) as Japan’s new Nationally Determined Contribution (NDC). Additionally, related documents indicate that in the commercial sector, energy-related CO₂ emissions are expected to be reduced by 79–83% by FY2040, reflecting increasingly stringent goals.
Meanwhile, the 7th Strategic Energy Plan identifies mandatory ZEB/ZEH implementation and thorough energy conservation as key policy pillars.
Needless to say, the two key factors determining the achievement of these targets in the commercial sector are energy conservation in buildings themselves and the decarbonization of the energy supply. Among these, given the burden on infrastructure, energy conservation on the demand side—within buildings—should be given top priority.
Commissioning is a consulting business that begins by helping building owners clearly identify the challenges in their own buildings, proposes the most appropriate solutions to address these challenges, and accompanies them through to their resolution. Because commissioning offers the most appropriate solutions to various challenges, building owners who are struggling with problem-solving can consult with confidence. Moreover, the wider adoption of commissioning will undoubtedly contribute to the decarbonization of buildings.
With the support and guidance of many stakeholders, commissioning has gradually become more widespread, and the awareness among building owners has increased. In fiscal year 2024, with the support of the Ministry of Land, Infrastructure, Transport and Tourism (MLIT), we were also able to develop the “Building Equipment Commissioning Guidelines for Building Owners.”
On the other hand, it is necessary to reconsider whether the framework that BSCA has taken the lead in establishing so far can adequately respond to the full-scale expansion of commissioning in the future, including how commissioning can be developed into a sustainable business.
The Building Services Commissioning Association (BSCA) intends to contribute to the realization of carbon neutrality. We sincerely appreciate your continued support and guidance.
Masaya Okumiya
