“The asthma symptoms have been dramatically reduced, enough that daily medication has been eliminated."

“Since moving into the Zero Energy Ready Home, we have found a vast improvement in indoor air quality. One of the occupants suffers from asthma. Since moving into the home, the asthma symptoms have been dramatically reduced, enough that daily medication has been eliminated. We attribute this to the tightness of the envelope … achieved through advanced framing techniques, various air-sealing measures, spraying the envelope with open- and closed-cell insulation. Incoming air gets processed through the ERV, a MERV 16 filter, UV sterilization, and dehumidification.”
