Design details and long-term performance of VIPs in Canada’s North
The research paper discusses the application and long-term performance of Vacuum Insulation Panels (VIPs) in the cold climate of Yukon, Canada, particularly in the context of building insulation. The authors, Doug MacLean and colleagues, highlight the increasing interest in VIPs due to their high thermal resistance per unit thickness, which allows for effective insulation with reduced wall thickness compared to traditional materials. The paper compiles design, field, and monitoring data from pilot projects aimed at promoting the use of VIPs to achieve Near Net Zero energy-use in buildings.
The introduction outlines the challenges posed by Yukon’s extreme cold, with recorded winter temperatures dropping below -55°C, and the regulatory push from Canada’s National Energy Code for Buildings (NECB) to enhance energy efficiency in construction. The authors note that while the benefits of VIPs are recognized, their widespread adoption is limited by a lack of understanding of their long-term performance and insufficient construction details.
Two pilot projects are described in detail. The first project involved a simpler wall retrofit design using two layers of mineral wool insulation and VIPs, achieving a thermal resistance (RSI) of 5.5. The second, more complex design utilized a combination of VIPs and additional mineral wool layers, resulting in a higher RSI of 11.5. Both designs demonstrated effective insulation, with infrared imaging confirming reduced heat loss in retrofitted areas.
Monitoring results from a separate location over five years showed consistent performance of VIPs compared to traditional polystyrene insulation, indicating their reliability in cold climates. The authors conclude that the successful application of VIPs can lead to reduced construction time and costs, and they encourage further exploration of VIPs in both new constructions and retrofitting projects.
This research paper is significant in the field of sustainable building practices, particularly in cold climates where energy efficiency is critical. It contributes to ongoing discussions about innovative insulation solutions that can help meet energy efficiency standards and reduce heating costs. By providing empirical data and practical insights from pilot projects, the article serves as a valuable resource for researchers, architects, builders, and policymakers interested in advancing the use of high-performance insulation materials like VIPs. The findings may encourage broader adoption of VIP technology, potentially leading to improved energy efficiency in buildings across similar climates.
