Don Hynek a hands-on three day training, April 12 - 14, 2012 in Aurora, Illinois. It is intended to teach protocols for testing multifamily buildings, how to assess a building, to plan efficient testing, the mechanics of using all major available testing systems, and acquiring & analyzing data. While the focus will be on residential buildings, the techniques and analysis methods involved are directly applicable to all types of conditioned buildings of less than 2 million cubic feet in volume. Participants will attend two days of classroom training and one day of field work performing multiple tests in an apartment building. As a result of this training you will be able to identify the appropriate test protocols for building configurations, determine appropriate test mechanics based on building systems, analyze blower door data from test procedures, identify problems, understand infiltration theory and calculate energy loss.
