It's getting hot in here!

Did you know that on this day in 1902 drawings for the worlds first air-conditioning system were created and submitted by Willis Carrier?

I would personally like to thank Mr Carrier for making the IET's office in Stevenage a pleasant environment to work in during this extended heatwave the UK is currently experiencing!

  • The first major office building to have air conditioning provided when built is generally accepted as the Milam Building in San Antonio, Texas, in 1928.  Other early air conditioned offices are few, but probably most notable are the PSFS Building in Philadelphia (1932), Metropolitan Life, New York (1933), and the Johnson Wax Administration Building in Racine, Wisconsin (1939). In the UK, one major building to be comfort air conditioned before the World War II was London’s Broadcasting House for the BBC (1931) Carrier . 1936 (first in the far east) The Hong Kong & Shanghai Banking Corporation, New Head Office, Hong Kong Air conditioned by G N Haden & Sons Ltd who provided ammonia refrigerating machines (410 hp) serving six air handling plants (229,000 cu.ft/min supply air),contract value being £75,000.  The first rush of UK air conditioned office blocks came in 1962: E S & A Robinson, Bristol; the CIS, Manchester; Shell Centre and Millbank Development in London.

    The period after World War II, up to around 1978, may be considered the boom years of air conditioning, but the 1970s saw the first major world energy crisis and spiralling energy costs. Air conditioning designers developed many forms of heat recovery system and apparatus, which were often omitted at the last minute on grounds of capital cost. However, the profligate use of energy became less and less acceptable. Lessons and ideas from the past were incorporated into new buildings: passive architecture, thermal storage, natural and nocturnal ventilation, reduced artificial lighting and better use of daylighting. Conventional comfort air conditioning for offices entered a period of decline. With increasing concerns over the ozone layer and global warming, it may yet give way to alternative environmental control solutions. (in italics produced by CIBSE Heritage Group).
