Green recovery, which accelerates decarbonization, and the movement toward carbon neutrality, which aims to reduce greenhouse gas (GHG) emissions to zero, are gaining momentum. The key to this lies in the “commercial and other sectors” and “residential sectors,” which stem from the energy used in buildings and homes. Air conditioning systems, which have a particularly large impact on personal comfort and productivity and are expected to continue to account for an increasing proportion of carbon dioxide emissions, will be introduced. This session will introduce natural ventilation and air conditioning systems that improve personal comfort and productivity, as well as systems that can efficiently control individuals’ personal spaces. At the same time, it will also highlight the need for human-centered control.
