Nikken Sekkei conceived and designed the new Daikin Vietnam headquarters building, which has achieved the world's first triple crown of Platinum environmental and health certifications.
Achieving top ratings in "LEED," "WELL," and "LOTUS" standards. Implementing architecture that balances environmental performance and well-being in Vietnam, where awareness of air quality issues is growing.

Nikken Sekkei Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director President and CEO: Atsushi Omatsu; hereinafter “Nikken Sekkei”), which conceived and designed the new Daikin Vietnam headquarters building, “Daikin Air Tower,” in Ho Chi Minh City, Vietnam, has received the highest Platinum rating under the international environmental certification“LEED” and the health certification “WELL,” as well as the highest Platinum rating under Vietnam’s environmental certification “LOTUS.” This is the first building in the world to achieve Platinum status in all three certifications.

In Ho Chi Minh City, Vietnam, which is experiencing rapid economic growth, there is growing awareness of air quality issues caused by fine particulate matter such as PM2.5 due to increased traffic and construction work. In this context, protecting the health of people working in the city and providing a safe and comfortable indoor environment is one of the most important themes in architectural design in Vietnam.

In this project, taking into account the growing air quality challenges in Ho Chi Minh City, we have realized our vision of "addressing Vietnam's air quality needs with Daikin's technology." By adopting Daikin's advanced air conditioning technology throughout the building, we have achieved both significant energy savings and improved quality of the living environment, such as a workspace with abundant natural light and a clean indoor air environment, through architectural innovations such as a high-heat-insulating glass facade and rainwater reuse. Furthermore, by introducing a system that allows for real-time monitoring of energy consumption and indoor environmental quality, we pursued a sustainable and comfortable office environment from both hardware and software perspectives. As a result, we have obtained the highest rank, Platinum, in all three of the following international environmental certifications for buildings and cities: "LEED (v4 BD+C ─ Building Design and Construction)," "WELL (v2 pilot)," an international certification focusing on people's health and well-being, and "LOTUS (New Construction v3)," an environmental certification by the Vietnam Green Building Association. Obtaining Platinum in all three certifications is a world first.

Comment from Managing Director Gopalakrishnan P.
Daikin Vietnam's acquisition of LEED Platinum certification for its headquarters building in Ho Chi Minh City is a truly impactful achievement in designing with sustainability and adaptability in mind, leveraging renewable energy, and prioritizing the user. This project demonstrates particularly outstanding performance in water resource management and indoor environmental quality, setting a strong benchmark for healthy, high-performance workplaces and solidifying its position as a strong candidate for LEED Zero.
Congratulations to everyone at Daikin Vietnam! And I extend my heartfelt thanks to Nikken Sekkei, Shimizu Corporation, Greenviet, and all other stakeholders involved. LEED on!

Comment from Jack Noonan, Senior Vice President and Asia Pacific Regional Representative:
Daikin Vietnam has created a strong competitive advantage in Southeast Asia by combining air quality visualization with biophilic design. The Daikin Air Tower, realized through collaboration with Nikken Sekkei, Shimizu Corporation, and Greenviet, is a prime example demonstrating that when a company prioritizes employee health, the built environment becomes the foundation for resilience and performance. By achieving WELL Platinum level certification, Daikin Vietnam embodies not only design excellence but also its corporate values and unwavering commitment to the people who work there every day. Congratulations!

Comment from Executive Director Douglas L. Snyder
