Building Science in Action (A Tour of UL’s Toronto Building Envelope Testing Lab)
This workshop will bring attendees directly to UL’s Toronto headquarters at 12:45pm for two presentations and a tour of the state-of-the-art building envelope testing facility. Attendees will be transported back to the Hyatt Regency at the end of the tour around 4:45 pm.
Impact of Fenestration on the Overall Performance of the Building Envelope
Windows and metal & glass curtain walls are important architectural features of buildings that generally represent as much as 40% to 100% of the exterior cladding of large buildings. The energy efficiency of buildings is a key technological and economic challenge facing the construction industry and fenestration is a determining element in the thermal performance of the vertical building envelope. As a result, increasingly codes are moving towards requirements for fenestration to exhibit thermal performance similar to that of opaque walls. This presentation will review why, given the effect of framing, attaining such thermal performance is practically impossible with the current construction methods and materials.
Evaluating the Laboratory and Field Performance of Building Envelope Assemblies of Large Buildings
Performance testing of building envelope assemblies is one of the best strategies to drive achievement of design requirements regarding air and water tightness, structural integrity (including loading from extreme events such as hurricanes and tornados), thermal and acoustical transmittance, and response to seismic events. Individual product testing is commonly undertaken to establish general market acceptance, while project-specific pre-construction mock-up and field testing are valuable elements of a quality control program to minimize risks for new building projects. This presentation will review the types of tests that can be undertaken, the testing process and the value of the output test results.
