This is old news really, new to me though.

There's a thread or two on here about members of ASHRAE. Here's a former member, a lawyer, who I once again have to wonder, why would he have anything to do with heating, refrigerating, and air-conditioning?:

Experts at ASHRAE Nix Smoking [06-24-99-5]

Experts at ASHRAE, the American Society of Heating, Refrigerating, and Air-Conditioning Engineers have changed their minds about smoking...

Recently, however, they voted to eliminate all reference in the body of the standard to smoking being permissible.

Below is a comment by law professor Richard Daynard who was instrumental in obtaining the change.

Note from Professor Richard A. Daynard,
Northeastern University School of Law:

...June 20, 1999, the ASHRAE (American Society
of Heating, Refrigerating and Air-Conditioning Engineers) Board of
Directors approved Addendum e to ANSI/ASHRAE standard 62-1989.

...eliminates all reference in the body of the standard to smoking being permissible...The rationale for this decision is that ETS is a known carcinogen, and there are no thresholds for safe exposure recognized by cognizant authorities.

This culminates a 13-year effort on my part to get the 1989 language...changed. I was a member of the ASHRAE committee that proposed the change. The tobacco industry...fought me (and, eventually, the great majority of the committee) at every turn.

Load the committee with anti-smokers and eventually the great majority (engineers maybe?) are gone.

It seems to me I recall reading somewhere that RWJF infiltrated, and now control, that outfit.
