Field Investigation of Mechanical Ventilation Strategies in Residential
Construction
The use of mechanical ventilation in houses has been the focus of increasing
attention in the home building industry due to concerns about the envelope
tightness of new homes and indoor air quality. To provide builders and
designers with more information about the use of mechanical ventilation
systems, the NAHB Research Center investigated the installed costs, operating
costs, and performance of whole house mechanical ventilation systems in new
homes. Test sites were located in Alabama, Maryland, and Minnesota. Each of the
test homes had three independent mechanical ventilation systems in order to
test different systems in the exact same house during varied seasonal
conditions. All of the homes were built with special attention to air sealing
of the building envelope. The main questions that this research answered were:
-
Do the mechanical ventilation systems achieve the air exchange rates that they
were designed to provide?
-
How much do they cost to install?
-
How much do they cost to operate?
-
What are some of the pros and cons of the systems that were tested?
