Demanding indoor climates
Large commercial premises typically have extensive floorage, high ceilings and a demanding indoor climate. The temperature must be kept stable all year around, in spite of the interiors producing excess heat for much of the day. In addition, there are the real temperature variations in different parts of the premises. Glazed areas give off thermal radiation, which counteracts the excess heat, and may require specific heating in fenestrated areas. All told, the picture is complex, and meeting all the requirements may not be straightforward.
