LIFE ENERGY ASSOCIATES, Concord, Massachusetts, President.
Indoor Air Quality Evaluation. Provide indoor air quality diagnostic and mitigation services, especially with regard to maximizing the healthfulness of indoor environments at the lowest energy cost. Services provided include helping clients achieve LEED IEQ Credits and Prerequisites, as well as performing assessments of the actual effectiveness of ventilation systems (in delivering outdoor air to building occupants) by both carbon dioxide measurement and sulfur hexafluoride tracer techniques. Tracer testing is also performed to assess leakage rates and identify pathways of air movement through enclosures (buildings, air-to-air heat exchangers, gas isolation boxes, mouse cages, anaerobic digester tanks, etc.) This testing has also been performed to characterize and quantify the amount of dilution occurring between sources, such as loading docks, and receptors, such as office spaces.
Full range of Industrial Hygiene services are also provided including the measurement and analysis of air contaminants either in achievement of the testing required for a LEED Credit or to assess worker exposures.
Performed measurements of specific indoor air contaminants, including respirable particulate matter, volatile organic compounds, radon, fungi and bacteria. Major study performed for Massachusetts Tobacco Control Program to measure the public's exposure to environmental tobacco smoke (ETS) in restaurants. Also available as a lecturer on Indoor Air Quality.
September 1993 to present
AIRxpert Systems, Inc. Lexington, Massachusetts. Director of IAQ Programs.
As a founding principal in this firm, responsibilities have included the development and refinement of monitoring equipment and techniques, as well as the recommendation of specific locations for sampling and the interpretation of the resulting monitoring data. Accomplishments have also included the preparation of articles for technical journals and presentations at conferences to share the information achieved with this high quality monitoring of carbon dioxide, carbon monoxide and absolute humidity.
