Correspondence to the supplementary opinions on alternative cooling technologies in hot climate

Summary, in English

At present, air conditioning (AC) is the most effective means for the cooling of indoor space. However, its increased global use is problematic for various reasons. This is a correspondence to the supplementary opinion provided by Dr. Bin Yang, Dr. Stefano Schiavon, and Dr. Faming Wang to our paper titled “Challenges of using air conditioning in an increasingly hot climate.” The paper explored the challenges linked to increased AC use and discusses more sustainable alternatives. The supplementary opinion provides a great technical complement to our paper. However, there is a need for a more holistic view both when it comes to combining various solutions and involving various levels in society.
