Abstract/Summary

The Simpson Strong Tie Demonstration Laboratory serves as a multipurpose space allowing students at the College of Architecture and Environmental Design at California Polytechnic State University to build full scale construction projects. The building features a material storage area, a high bay for construction of full-scale projects, and a mezzanine level that houses digital fabrication equipment. However, the building was never designed to house the specific equipment currently installed on the mezzanine and ventilate the exhaust fumes from them. Rather, the building relies on passive natural ventilation that is likely ineffective at properly exhausting hazardous fumes, resulting in complaints from students. This paper will examine the current problems with the Simpson Strong Tie ventilation system and determine how to satisfy the criteria set forth by the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE), using a qualitative occupant survey. By doing so, the paper will make a case for an Environment, Health, and Safety (EHS) air quality test to allow for future renovations to improve the safety of the space.
