About the Presenter: Phalguni Mukhopadhyaya, PhD, P.Eng – University of Victoria
Phalguni Mukhopadhyaya, PhD, P.Eng is an Associate Professor in the Department of Mechanical Engineering (Civil Engineering Program) at the University of Victoria, British Columbia, Canada. His research interests are in energy and moisture performance of building materials and envelope systems. Presently he is working on next generation thermal insulation materials (VIP, Aerogel, Bio-foam etc.) and systems, and their integration in the built environment construction. Phalguni has authored/co-authored about 150 technical publications and reports, co-edited two ASTM (American Society for Testing and Materials) STPs (Special Technical Publications) 1495 & 1519 and edited one conference proceedings (see http://www.ivis2011.org). At present he is the Technical Co-Chair of the upcoming, October 2016, ASTM International Symposium on Advances in Hygrothermal Performance of Building Envelopes: Materials, Systems and Stimulations, and elected member of the ASTM C16 Executive committee C16 on Thermal Insulation.
About the Topic:
Service-Life Performance of Vacuum Insulation Panels (VIPs) in Building Envelope Construction
Building energy code updates and stringent energy efficiency requirements arising from global movement towards heavily insulated net-zero building construction have created a historic opportunity to integrate vacuum insulation panels (VIPs), having 5 to 10 times higher R-value/inch than traditional thermal insulation, in building envelope construction. However, one of the biggest challenges faced by the manufacturers, researchers and building envelope designers is to recommend a long-termthermal-resistance (LTTR) value for VIPs based on expected service-life of the construction. This presentation will outline the issues related to the LTTR of VIPs, present observations from field and laboratory studies, and summarize global initiatives to address this question.
