This paper provides an insight into the new ASHRAE Hot Climate Design Guide which is currently in progressand due for publication in 2018.

This guide compliments the existing Hot and Humid design guide by focusing onto other climate regions – Arid, Temperate, short term hot with cold winters, i.e. the two extremes during a year. The guide also addresses the challenges facing building service engineers who must develop design solutions which are affordable to construct, affordable to operate, reduce energy consumption and meet carbon emission targets which are now being set by Governments around the world to address climate change issues.
