What is a thermal zone? Most spaces in most buildings aspire to maintain some kind of comfort. This is usually expressed in terms of temperature and usually as a range (say 21-24C or 70-75F). It could be said that as long as a space is within the range, it's met its comfort aspirations.A central HVAC system may serve one or more thermal zones, and its major equipment is located outside of the served zone(s) in a suitable central location whether inside, on top, or adjacent to the building [4, 5]. Central systems must condition zones with their equivalent thermal load. Central HVAC systems will have as several control points ...Achieving thermal comfort requires not only thermal regulation of the building's macroenvironment, but also personal thermal management.

Every zone contains one or more Spaces. Space is an optional input. If a Zone has no Space(s) specified in input then a default Space named <Zone Name> will be created. If some surfaces in a Zone are assigned to a space and some are not, then a default Space named <Zone Name>-Remainder will be created.Zoning one-fourth of the mosque area with thick transparent plastic sheets as a thermal barrier was shown to reduce the required cooling energy by more than 30% (Al-Shaalan et al., 2014).
