My professional background is as an engineer with a PH.D in Mechanical Engineering. I have worked in the private sector and for several federal government agencies. The government agencies include the Defence Research Board (design of the DDH280 destroyer and the Gentilly Nuclear Reactor, 1965-72), Public Works Canada (bridge and marine engineering technology development and building energy conservation, 1972-82), the National Research Council and Health Canada (indoor air quality problem solving, 1982-88).
For the past 20 years I have owned and operated a consulting and technology development firm, Indoor Air Technologies, specializing in indoor environment problem solving in buildings and aircraft. This firm has problem solving ventilation technologies licensed in the building and aircraft fields. One of these, the ECHO System (a basement radon gas and water entry prevention and mold exposure and odor mitigation system), was installed in 1992 in the Prince Edward Island energy conservation demonstration house.
I have conducted over 400 indoor air quality investigations in all sorts of indoor environments. In the course of this work, I have developed protocols for investigating systemic sources of a number of indoor air contaminants and for measuring ventilation and sorption parameters. I'll provide more information concerning my findings in future articles.
With the Indoor Air Technologies blog I intend to address indoor air quality (IAQ) problems and solutions in buildings and aircraft. I'll also be discussing our ECHO Air, VEFT, PEACE and ECHO Systems technologies. I invite you to drop by on a regular basis.

Do you have any information regarding the effectiveness of air filtration during specific pack settings? Specifically, the Airbus 320 series pack system run in low flow as opposed to normal or high flow. The books I have only indicate that the system operates at 80% in the low flow postion but soesn't reference how this affects the air quality or filter effectiveness.
Thank you,
