The RPA I Ecocor base model homes are designed with a shallow frost protected foundation. The foundation includes insulation formwork which stays in place after the concrete slab is poured. This is the most efficient and cost effective type of foundation system for meeting the Passive House standard. Our wall panels and roof can be installed on any type of foundation system including a basement, crawl space, or even piers provided that the proper levels of insulation have been engineered into the foundation.
