Well-insulated homes have low heat loss and gain and are great for energy savings. Most people think it would be easy to provide HVAC comfort; however, these types of home designs with tight envelopes tend to retain moisture, and take much longer to reach a low sensible heat ratio. A typical size home in America is 2,000 – 2,500 ft2 with a design airflow of 1200 CFM. The same size low load only requires 600 CFM. This session addresses the challenge of low airflow rates in residential dwellings and how to mix the conditioned air to promote even temperatures.
