![]() Most of them are up against a perimeter wall. I explained that radiators function as the name implies to radiate heat, 360 degrees. I pointed to the baseboard fin tube radiators and said that’s the biggest problem on older buildings, not windows (those are 2nd). We got to talking about preservation and energy retrofitting older buildings. ![]() We got to thermal transmittance (U-value and R-value) measurements and we showed them our system and explained how it works. We talked about measurement and verification and some of the things we have seen as the testers that can be improved in the construction and renovation process. He spends most of his time annoying buildings.Yesterday We had an opportunity to host some folks from our local nyc dob at a project we are doing down the block from their offices. Gary has a Bachelor's degree in Mechanical Engineering and a Masters in Building Science. He has served on the Part 9 Committees of both the National and Manitoba Building Codes as well as several CSA and CGSB committees. is a mechanical engineer with over 40 years of experience in building science, energy management, research and training. Kevin sat on the ULC Standards Committee for Air Barriers, and CSA Z320 Building Commissioning Architectural Subcommittee. He currently sits on the ASTM E06 Performance of Buildings co-chair for the Standard Practice for Enclosure Commissioning, and chair for the Enclosure Commissioning Training and Certification, is a member of Society of Protective Coatings and Chairs the Commercial Air/Vapor Barriers Committee. He has had numerous papers published in Canada, United States and Europe, and is a frequent lecturer on building science. Kevin has collaborated with federal and provincial governments, utilities, and private sector companies on many projects.

Kevin Knight is a building envelope authority with over 30 years’ experience in field observation and testing, commissioning, research, education and training. The workshop will close with the tales of ordinary madness that comes with testing occupied buildings. The final test was conducted by a small army of RRC, Manitoba Housing and Manitoba Hydro staff and students. Starting with a small and simple single storey building with 12 suits and concluding with a 13 storey with 107 suites. Once the theory of the test was proven we then moved on to four occupied buildings. This workshop will walk through of the two phases of the research project, firstly trying the concept of the test method on unoccupied buildings, one small and simple and the second a six storey building with a 124 suits. Occupant access has to be limited during certain critical parts of the testing, interior doors must be kept open and suite windows have to be kept closed. However, if the building is an occupied MURB, then major issues arise. For unoccupied buildings, this is seldom a problem. Manitoba Housing supplied all the buildings and support from their staff, Manitoba Hydro proved technical and staff support.Ĭurrent air leakage test methods and standards are predicated on the assumption that the testing agency has complete control over the building and its operation during the test period. In September 2014 Red River College (RRC) was contracted by Canada Mortgage and Housing Corporation (CMHC) to explore some of the unique problems associated with performing airtightness tests on occupied Multi-Unit Residential Buildings (MURBs).
