ASHRAE Insights - April 2009 - (Page P7) ASHRAE Insights April 2009 based on the requirements for determining the outdoor air ventilation rates. By restricting the design of the mechanical ventilation systems to be as per the Ventilation Rate Procedure described in ASHRAE Standard 62.1-2007 (or more stringent local codes), one may not realize the implied goals of improving the indoor environment or energy conservation. The implications of EQ (Environmental Quality) Prerequisite 1: Minimum IAQ Performance Required and EQ Credit 2: Increased Ventilation on indoor air quality and building operating costs will be explored. Tuesday • Cost impacts of ASHRAE’s new IAQ guide. • H V A C a p p l i c a t i o n s s e s s i o n s : cleanrooms, indoor sports facilities, entertainment venues. • Laboratory exhaust and design sessions • Fans’ contributions to achieving Standard 90.1. • Live debate: are cities sustainable? • Buildings update: the first 100 days. • Meet the authors: 40 papers are presented in the one-on-one, Q&A discussion-format poster session. Forum 5 (Basic) Are You Ready for HACCP?: Management, Operations and Financial Implications of a Legionnaires Disease Hazard Analysis? Track: Operational Topics Sponsor: SPC188P 3.6 Water Treatment , Chair: Michael P Patton, Member, Dolphin Wa. terCare Divsion of Clearwater Systems Corp., Essex, CT For a number of years, Hazard Analysis and Critical Control Point (HACCP) plans have been utilized in the food industry to reduce transmission of infectious organisms from food to humans. Because of the success of HACCP in that industry, SPC 188P, Prevention of Legionellosis Associated with Building Water Systems, may choose to adopt HACCP as a systematic disease prevention strategy for legionellosis. Any HACCP plan will necessitate certain responsibilities on building owners and operators which will affect the operation of their buildings. This forum explores the potential managerial, operational and financial implications that a HACCP plan may engender, and provide further guidance to SPC 188 in its development of this standard.

Transactions 10 (Intermediate) Cleanroom Energy Consumption and Humidification Track: Applications Sponsor: 9.11 Clean Spaces Chair: Wei Sun, P .E., Member, Engsysco, Inc., Ann Arbor, MI Energy consumption is typically much higher in cleanroom facilities than general-purpose buildings, the new criterion called Specific Energy Consumption (SEC) provides a less-bias comparison methodology of energy usage. The author benchmarked SEC values collected from many semiconductor and electronics fabrication facilities, and further proposed innovative energy efficient design approaches in ventilation system to save energy consumption. Another author addressed various humidification approaches for large-scale cleanrooms, and found out that relative humidity (RH) distribution and time-based RH variation in the cleanrooms can be controlled within a small tolerance by using direction humidification in return chase with high-pressure water atomization through spray nozzles, this methodology utilized less energy than other conventional humidification approaches. 1.

Ezzat Khalifa, Ph.D., Member, Syracuse University, Syracuse, NY Personalized ventilation systems (PV) have been shown to provide much higher breathing zone air quality at lower energy consumption, and to enhance human comfort, perception of air quality and productivity. In most PV systems, air is introduced by one or more nozzles or air terminal devices (ATDs) placed in the vicinity of the person. The jets produced by these devices interact not only with the human thermal plume and breathing but also with the flow fields induced by general ventilation systems, creating a much more complex flow, temperature and concentration fields with much steeper gradients around the person than conventional mixing or displacement ventilation systems. 1.

Madison, Madison, WI Only recently have building simulation programs started to tackle the task of simulating load and energy consumption of refrigerated storage facilities. Government and owners realize the large amounts of energy these facilities consume and are eager to find opportunities to reduce this cost. Two software packages, DOE 2.2R and Energy+, are both developing refrigeration components to tackle this problem. This seminar introduces these programs to the audience and show an example of what is currently possible. 1.
