ASHRAE Series Continued: Excerpts from the 1924 ASHRAE GUIDE
ControlTrends invites you to keep a continuous glimpse in review of how our industry’s engineering scaffolding was put into place and ASHRAE’s unending quest for industry standards and excellence.


The lineage of the Handbook begins in 1922, when the American Society of Heating and Ventilating Engineers (ASH&VE) published its Heating and Ventilating Guide. Its purpose was stated as follows in its preface:
‘The purpose of this new addition to the Society’s publications is to provide the engineer, the architect and contractor alike, with a useful and reliable reference data book relating to the art of heating and ventilating. [Read more...]

ASHRAE Series Continued:The Most Ancient Rule Known to Engineers,the Rule of Thumb!

Continued Source: Chapter 1, “A Long, Strong Pull Together”
In the late nineteenth century, the science of heating and ventilation was not well understood. When installing heating and ventilating systems, most contractors based their calculations solely and unquestionably on data in fan manufacturers’ catalogues. Only a few contractors were educated and had formal training in engineering.
Perhaps the best summary of the late 1890s was written by Stewart A. Jellett, a charter member and the second president of The American Society of Heating and Ventilating Engineers. He explains: “Until about 1890 the business of heating and ventilating had been largely based on the most ancient rule known to engineers, the rule of thumb…I believe it was the stress of competition, the commercial side of the business, that finally forced the recognition of the necessity for more scientific consideration, both in regard to the manufacture of the apparatus and in its application for regular work. “Between the so-called ‘Heating and Ventilating Engineer,’ who did not understand his business, and the heating and ventilating engineer who was 75 per cent. fakir [sic], the public was getting but a poor return for its money.
