However an appendix is provided with procedures establishing additional ven- tilation rates required to maintain acceptable perceived indoor air quality in the presence of tobacco smoke. 9 Outdoor air venti

This is offset by a requirement to maintain an overall supply rate com- posed of filtered recirculated air plus outdoor air, intended to reduce the con- centration of bio-contaminants that can contribute to disease transmission. Ventilation

The benefits of more complex multiple space sys- tems, suc

Requirements for ventilation system design have been expanded, TaJlOr including requirements for service acces: to equipment, separation of air intake: and exhaust (including the effects ol exhaust flow

Iiiixpxiicd Group Discusses Issues, Ethics OfAdding Substances to Air SAN ANTONIO-A growing trend in other countries o

30、f putting addi- tives into the indoor environment through HVAC systems has sparked the interest of ASHRAE members. It has raised the question “Can Indoor Air Environments Be Enhanced by Adding Substances to The Air?” James E. Woods, Ph.D., P.E., Fel- low ASHRAE and professor at the Virginia Polytech

31、 Institute, moderat- ed a foruni at the ASHRAE Annual Meeting that explored the issues of substances added to occupied space through HVAC systems. The issue evoked a discussion that ranged from the possible benefiis to the responsi- bilities and liabilities of implement- ing such a technology. Some

32、of the technical issues dis- cussed centered around how the sub- stances should be added, the chemical characteristics of the substances, expo- sure levels (allowable and effective), and how human responses should be measured. Since it is known that the olfactory senses have a direct effect on the w

33、ell being of humans. a question was also raised as to how the substances can be characterized. If a chemical sub- stance is used that alters behavior, is it to be considered a drug? If it is classified as a drug then there are other issues that must be resolved re- garding health. These issues inclu

34、de the right of choice to exposure from a standpoint of health if allergies are possible, and from a ethical point of view if it is mood-altering and classi- fied as a drug. In addition, engineers must fully understand what the stimuli does and how it affects various age levels. Further discussion n

35、oted that addi- tional technical data is needed and that ASHRAE-funded research projects would be needed that could provide any available literature and data on long and short-term exposure through literature searches in the air freshening and fragrances fields. Technical infor- mation will also be

36、required that could provide guidelines for injection, moiii- toring and control. Concerns were also expressed about maintaining use of additives to the air in a recirculating A/C modes where counter-balancing forces would be needed. The effects upon filtration systems would also require study. It wa

37、s also noted that air satu- rated with humidity hydrates some chemicals. The questions about putting addi- tives in the air through the use of HVAC system are many and it was agreed by those present that more in- formation will be needed before pro- ceeding further. The fundamental question still re

38、mains: Can indoor en- vironments be enhanced by adding substances to the air? More informa- tion and research will be forthcoming in the future in an effort to answer this question.

He said users now must “wade through the chaos“ but he believes that will change in time. Suc- cessful implement

ASHRAE Home Page editor, said hes been pleased with thc response and acceptance of the cite (ht- tp:/www.ashrae.org) which has been on

41、line since October. He said the Horne Page is now undergoing several im- provements. The improvements include a redesign which will make the page easier to nav- igate, and improved search capabilities, initially in the area of publications. The ASHRAE.

44、ndrew Nolfo, P.E., Member ASHRAE, of Murphy Company in St. Louis. provided the perspective of the mechanical contractor. He said bidders should be pre-qualified, and that com- missioning should start at design. He said that professional fees should not be based on a percentage of construction costs

45、since those costs have risen in a greater proportion than constiuction costs. A better system. he said, might be to base professional fees on a percentage of energy savings, a percentage of main- tenance/operational costs saved, and-or a percentage of cost-avoidance.

Carl Lawson. the seminar moderator, said comments from the speakers and at- tendees indicate that the prolessio

48、n must accept the consequences of taking projects that dont provide appropriate compensation. Many of these pro.jects. he noted, have unusual requirements and conditions. “We must maintain our responsibili- ty. professionalism and credibility,” he said. “We as engineers and contractors in a way take

49、 more responsibility than any other profession, with the exception of the medical profession.” The bid/fee shopping should stop, but probably never will, he said. “In some cases, engineers are going to have to re- invent the word no. w 22 ASHKAE .rolir?7ui August 1996 0759650 0524843 877 hulatiom for mechanid systems Operating temperature limits of Owens-Cornings full line of Fiberglus Insulations. nwIypesI At 25% deformauon . 90 Ib/k (4309 Pal Density: Insul-Quick 3.0 Ib/ft3 (448 Wm3) “iv Type II, . .: 23 lb/ftj (36 Wm? w*Mporsapliim . 2.0%by* Flame spr
