Whole building retrofit using vacuum insulation panels and energy performance analysis
Highlights Performed a whole-building envelope retrofit using low-cost VIPs in a cold climate. The study showed VIPs to be feasible and durable retrofit strategy with a 1.5% loss rate. Performed whole building energy modeling using EnergyPlus. Simulation showed significant reductions in annual heating energy consumption due to the envelope retrofit.
Abstract Vacuum insulation panels (VIPs), due to their high thermal performance, provide an attractive alternative to traditional building insulation materials, especially as an option for retrofitting old, poorly insulated buildings. This article describes the complete retrofit of all exterior walls of a single-story building in a cold climate using VIPs. A recently-developed low-cost VIP, called modified atmosphere insulation (MAI), was used in this study. Two buildings of near-identical construction were studied, with one remaining unaltered and serving as the baseline while the other served as the retrofit building. The VIPs or MAI panels proved to be a feasible and durable option for retrofitting building envelopes. Thermal performance of both buildings was analyzed using in-situ temperature and heat flow sensors. Numerical models of the two buildings were created, benchmarked using experimental data and used for predictions of annual energy savings due to the addition of MAI panels to the exterior walls. The models predicted significant reduction in the annual heating energy consumption in the retrofitted building compared to the baseline building.
