While such an example does not prove conclusively that all south-facing

rooms in the United Kingdom need to be air conditioned for human thermal

comfort, it does give some evidence to strengthen the argument in favour of

mechanical cooling. Working in air temperatures that move above 24 °C d.b. in

naturally ventilated spaces that have significant solar radiation can be noticea-

bly uncomfortable. Whether the performance of human productivity or effec-

tiveness becomes impaired is arguable. Low-cost cooling systems can be de-

signed that make use of cool parts of a building to lower the temperature of the

areas that are exposed to solar radiation. Heat pump systems, mechanical venti-

lation and evaporative water-cooling towers can be used to limit room air tem-

peratures, without the need to involve high-cost refrigeration equipment.
