Residential Ventilation - new requirements, new systems, new issues

Until recently, residential ventilation has consisted mainly of installing bath fans and kitchen exhaust hoods, but that has changed with the new code requirements for testing, and with tighter houses driving the need for balanced ventilation. Learn why something as simple as a bath exhaust fan may not deliver anything close to the specified air flow, and why. New homes in Massachusetts. must have ventilation flows measured by an approved 3rd party that meet a written specification – or no Certificate of Occupancy. See data from exhaust only and balanced ventilation systems that graphically depict a surprising difference in CO2 levels. Learn what ‘commissioning’ means, and why both Passive House and ENERGY STAR require verification of ventilation system airflows.

For those who qualify, 1.5 LUs are available.
