Hong Kong companies have turned up the temperature dial in air-conditioned offices and are using an array of approaches including digital technology to reduce energy consumption and carbon emissions. Developers including Swire Properties, Hongkong Land, Sun Hung Kai Properties, Hang Lung Properties, Sino Land and Link Reit are among the entities working to fight climate change.

Swire Properties has implemented different control strategies, such as raising the temperature of the chilled water in its air-conditioning systems to reduce energy use. Digital panels have been installed in the lobbies of office buildings to display indoor temperatures to raise tenant awareness. Hongkong Land introduced a mobile phone app that allows its tenants to save energy by managing the air temperature of their premises. Link Reit said it has an energy management team that works with on-site staff to adjust its properties' air-conditioning temperature in accordance with the Hong Kong Observatory's weather forecast to facilitate energy savings.
