Woods, chairman of the ASHRAE stan- dards project committee. "In smoking areas, the costs of both installing and operating air handling systems probably will increase,"- Woods said, but de- clined to speculate on the amount of increase. A spokesman for the Energy Department, who has run computer analysis of the stan- dard's impact on commercial buildings, sai(T that in a worst- case situation, assuming every- one in a building smoked, the standard could double heating and cooling costs and required equip- .ment capacity, also raising peak demand. However, both noted that the standard also includes a specif- ication linking the amount of air recircufation permitted with the . efficiency of a building's air cleaner. "This will allow engi- neers to make trade-off decisions among air cleaner efficiency,: pressure drops,' and fan'.horse- - power,,' _ Woods noted. _~, Woods said ASHRAE plans aa formal study on the cost impact of the standard, but "my personal - opinion, based on a consensus review we made on the standard, is that for non-smoking areas, the cost impact should be negligible • compared, to ihe previousjtan-;,- ~ dard;'',;he. said.t!'I( an y•thing _tberr' ;~ new,_standar3.•should promotiei-- 3 i . - energy ;-sAvings,: because couples filter efficiency with the .` `.' ventilation rate.,". - • ASHRAE representatives said : they expect ASHRAE 62-1981, or =• "Standards forrVentilation Re•,, t:• . - quired for Minimum Acceptable ~ Indoor Air Quality," to be~ in- ' crorporated in the building codes of many states, beginning in four or five months.; Si; . ` ry - C- _1 - -- .S_
