Vacuum insulation panels (VIPs) can help achieve thin, highly insulated building envelopes, but poor implementation and insufficient ventilation can lead to durability issues. This thesis describes a field study that was used to characterize the durability of a research house with a thin, VIP-integrated building envelope and an energy recovery ventilator (ERV). The study employed long term hygrothermal monitoring of the building envelope and various tests to evaluate the insulation performance, airtightness, and ventilation effectiveness. The impacts of VIPs and ventilation on durability were discussed, with emphasis on moisture buffering, drying potential, mold growth risk, and VIP aging. The house demonstrated exceptional insulation performance with no risk of visible mold growth during the study. The walls and floor showed acceptable conditions for VIP longevity, and the ERV showed a potential to sufficiently buffer indoor moisture loads. Recommendations were provided to improve the durability and efficiency of the house.
