Ventilation
The natural ventilation rate of SIP buildings shall not be less than that required by the local code or 0.35 ACH when no local code exists. When required, mechanical ventilation shall be provided to meet the minimum air exchange rate of 0.35 ACH. A properly constructed SIP home has a very low air infiltration rate. That’s great for reducing heating and cooling costs, but it isn’t always healthy for the home or its occupants. It is strongly recommended that a whole-house ventilating system be installed at the time of construction.
