Countries that have extreme heats tend to follow the urban heat island effect, in which building cooling is mostly necessary amongst many buildings and the CBD areas. With that said, greenhouse gas emissions and building energy consumption continue to have an increased growth rate. The article mentions that, “this paper discusses the existing space cooling technologies and their suitability to provide comfort cooling in the context of warm and humid climates.” Further, alternatives for space cooling regarding low carbon has been reviewed and the strategies regarding decarbonization have been carefully considered. With a warming climate and the earth's surface surface reaching extreme temperature the decarbonization of buildings need to be accounted for and need to be placed in the policies.The article also mentions the need for a reduced energy demand will be obtained by having energy efficient buildings.
