Build it Tight. Ventilate Right. We hear a lot about the former, what about the latter? Listen in on this episode of RESTalk as we chat with Scott Grefsheim, a Senior Product Engineer at Research Products at AprilAire, as he shares his 25-year passion for building products that improve health and comfort in homes and buildings. Scott covers how various types of products and controls perform the basic role of ventilation– to dilute the indoor pollutants to acceptable levels while maintaining occupant comfort. And we discuss his complex role as a product engineer to define product specifications to satisfy building occupants, builders, dealers, energy raters as well as codes. As he notes, “RESNET and energy raters have become our customers. We’ve heard what they’ve said, and that’s how those product ideas evolve.” Scott shares three key points of advice for Energy Raters: 1) Know the (air) flow that is required in the building you are testing. This can come from the codes or tables or some calculators/programs. 2) Don’t overventilate, as that brings on additional energy needs of heating or cooling or dehumidifying or humidifying the ventilation air. 3) Install properly and measure performance; being certain that you are using the appropriate controls Additional resources are available at www.AprilAirePartners.com Learn more in person – professionals in the building industry should consider attending the RESNET annual Building Performance Conference which will be held in New Orleans, LA Feb 25-27, 2019.
