Waseda University released a statement to say that it has reached a collaborative research agreement with Mitsubishi Electric Corporation, the Technical University of Denmark (DTU) and the University of Sydney to create a new “thermal comfort index” which will better predict how people feel indoors.
The project is more than just traditional indoor climate control methods. The aim is to go beyond the long-established PMV standard and develop an index capable of capturing varied individual thermal feelings — hot or cold — instead of depending on an average. The four institutions will cooperate through merging skills in environmental control systems, building science, sensor information, human behavioural science and control technology.
Mitsubishi Electric will be responsible for demonstration planning and offering test environments, such as the Zero Energy Building (ZEB)-related technology demonstration building “SUSTIE®”. Waseda University’s group, led by Professor Shinichi Tanabe (Faculty of Science & Engineering), will prepare subject questionnaires and demonstration plans. DTU and the University of Sydney bring their world-leading architectural environmental analysis capabilities.

Why This Collaboration Matters for Japan’s Tech Industry
The new research initiative is more than a scholarly exercise; it has substantial implications for the technology ecosystem in Japan:
Demand for sensor and data-integration technologies: Creation of a thermal comfort index taking into consideration individual characteristics (age, metabolism, clothing, activity level) and indoor environmental conditions (temperature, humidity, air velocity, radiant temperature) will call for advanced sensor networks, real-time data acquisition and algorithmic modelling. Japanese technology companies that are experts in IoT sensors, edge computing and machine-learning analytics will have fresh opportunities.
Smart‐building and energy-efficiency innovation: The research is in line with Japan’s drive towards sustainable buildings, decarbonisation and wellbeing at the workplace. Smart-building companies—hardware, software and systems integrators—can use this research to innovate solutions that dynamically adjust indoor spaces based on personal comfort, as opposed to fixed set-points.
Global standardisation leadership: The alliance clearly seeks to introduce the new comfort index into international standardisation. That creates an avenue for Japanese technology companies to shape global standards, install their technologies in the global market and achieve exports of building-control solutions, sensors and software platforms that are compatible with the new standard.
Cross-industry spill-over: Indoor thermal comfort technologies developed (control algorithms, sensor networks, occupant modelling) can be leveraged for other industries—automotive cabin climate control, wearable devices that monitor thermal comfort, or aerospace/mobile habitat environments. Japanese businesses with agile tech stacks can tap into these neighboring markets.
Effects on Businesses Operating in the Industry
Companies already established in building-technology, environmental systems, and digital infrastructure will experience the ripple effects:
Facility managers and building systems integrators: When this research continues to evolve and new indices become available for commercial use, building owners and managers could need to upgrade HVAC control systems, incorporate personalised comfort management and deploy new arrays of sensors. Service companies and systems integrators should begin to prepare to provide next-generation solutions.
Sensor, hardware and component makers: A requirement to track more parameters (e.g., occupant metabolic rate, clothing insulation) will necessitate novel sensor types, wearables or ambient monitoring hardware. Japanese component producers can create and provide these to the expanding building-automation and smart-workspace industry.
Software companies and analytics vendors: With greater data from occupants and spaces, the demand for occupant comfort modelling, analytics, control-system algorithms and dashboard platforms will increase. Japanese software companies should expect this trend and gear analytics frameworks specific to this new index.
Energy-management and sustainability service providers: The pressure for comfort and wellbeing is also compatible with energy-efficiency objectives. Energy-management companies can leverage the new comfort index to maximize building energy consumption while ensuring occupant comfort—a vital distinction in corporate sustainability initiatives.
Global-expansion potential: As the project seeks international standardization, Japanese companies involved in these technologies would be able to target export markets in Asia, Europe and other parts of the world. Early mover advantage now can pave the way to more long-term contracts and competitive edge when the index is globally adopted.
Strategic Considerations and Challenges
Although the announcement is encouraging, companies ought to be mindful of the following factors:
Commercialisation timeline: Time will be required for research to project to standardisation. Companies need to track progress but also to meet near-term requirements and incremental improvements in place of waiting for the ultimate standard.
Interoperability and ecosystem readiness: There is a new comfort index, which demands sensor ecosystems, data platforms and control infrastructure to combine with current building management systems. Companies might have to collaborate, frame to fit and invest in interoperability.
Market adoption and cost-benefit balance: Operators will balance value for personal comfort against cost. Technology companies will need to provide business cases that illustrate enhanced wellbeing, productivity or energy savings in order to promote adoption.
Data privacy and occupant monitoring concerns: Personal traits like clothing, activity level or metabolic rate include personal data. Companies need to have mechanisms in place for ensuring privacy, data-governance and occupant consent.
Looking Ahead
The Waseda-Mitsubishi Electric-DTU-Sydney alliance heralds a larger movement: the convergence of occupant-focused comfort, sensor technology and building systems. Future developments expected are:
Commercial pilot schemes incorporating the new thermal comfort index into smart-offices or co-working environments, employing real-time monitoring and adaptive HVAC management.
Cross-sector technology transfer in which indoor environmental systems borrow from automotive, wearable or industrial-automation comfort modeling.
Conclusion
The collaborative research project inaugurated by Waseda University, Mitsubishi Electric, DTU and the University of Sydney is a positive step for Japan’s technology and smart-building industries. By striving to create a better thermal comfort index for capturing individual feelings and driving it towards international standardisation, the project opens up new technology, business and export opportunities. For Japanese tech companies, now is the time to convert to systems, build alliances and gear up for this next wave of building-environment innovation. The building of tomorrow is poised to be not only efficient—but personally comfortable, dynamic and intelligent.
