High-Rise Social Housing in Hot-Humid Climates: Towards an ‘Airhouse’ Standard for Comfort
The pressure to provide social housing in a fast and economic way, as well as outdated regulations, constrain the design of these buildings, having serious implications for the comfort of occupants and the environment. This becomes more critical in hot-humid climates, such as Malaysia, with uniforml...
