At UNC we are evaluating the benefits and risks of various laboratory ventilation designs for new construction and renovation projects. We have benefited from discussions with safety personnel and engineers from several campuses. However, a broader perspective of the academic community would be of great value as well. Many of the older laboratory designs incorporate constant volume exhaust systems (CV). Newer systems may include Variable Air Volume (VAV) controls on the supply and exhaust equipment. Below is the URL to a survey of 21 questions related to issues surrounding College and University Laboratory Ventilation design focusing on their safety, reliability, and energy savings for both VAV and CV systems. Please try to answer as many questions as you can. If you do not know an answer and are unable to readily obtain this information, just leave that question blank. Individual responses will be pooled with the other respondents. At the end of the survey, you will have the option of viewing the results of this pooled data. The survey will be posted for a month. Thank you in advance for your assistance. Gary Shaver EHS UNC-Chapel Hill http://www.zoomerang.com/recipient/survey-intro.zgi?p=WEB2242MRU7CGU
