Together, we develop and test new methods to increase energy efficiency and improve environmental performance in our projects. This collaboration continues to generate substantial energy savings and allows us to share new ideas and practices with our employees, business partners, industry peers and other researchers. We are working to push the boundaries of traditional building management by developing new AI technologies, improving indoor air quality (“IAQ”) control measures, increasing the generation and use of renewable energy, and other measures to make our portfolios even more energy efficient and sustainable. Highlights of our partnership in 2022 included: • Retro-commissioning work at Taikoo Li Qiantan • Developing AI technologies for plant optimisation and smart facility management • Developing DC microgrid guidelines and reviewing the DC microgrid pilot project design • A whole-lifecycle building carbon emissions study where an accounting tool was developed and adopted by the INDIGO Phase Two extension development project.
