Why do SIPs Buildings require Mechanical Ventilation?
As we have insulated and sealed homes to achieve greater levels of comfort and energy independence, structural insulated panels have proven themselves to be the most cost effective and stable method of construction. Although this simplified process of super-insulation has shown positive impacts on the quality, comfort and energy savings of structures, it also created the need for controlled ventilation. Many of today’s indoor airborne pollutants can be effectively controlled, actually increasing the comfort and livability of a structure.
Mechanical ventilation has been proven effective in mitigating fumes from combustion appliances, radon, formaldehyde and even pollutants such as excess humidity and tobacco smoke.
In order to remove the contaminated air, an exhaust is essential. Typically, that exhausted air is the replaced with fresh air from outside the structure. It is recommended that builders and homeowners work with a qualified HVAC professional familiar with ASHRAE 62.2, the standard for Ventilation and Acceptable Indoor Air Quality in Low-Rise Residential Buildings and the local building codes.
