This course from April 17 to April 20 will teach advanced theory and applications of infrared thermography in the preventive maintenance, quality assurance, condition monitoring and non-destructive testing of materials, with an emphasis on building envelope components such as wall assemblies and roofs.

The Building Envelope Technology Access Centre (BETAC) team has partnered with the University of Manitoba and consulting firm Crosier Kilgour and Partners to develop a new thermal break, or barrier, to help reduce significant heat loss that occurs in high rise buildings with large concrete balconies.
“Commercial alternatives of thermal breaks are available but prohibitively expensive,” said researcher Dagmar Svecova in ResearchLIFE, a University of Manitoba magazine. Read More →
A team of researchers at the Building Envelope and Technology Access Centre (BETAC) partnered with SMT Research to monitor the structural health of the Skilled Trades and Technology Centre (STTC) being built at Red River College.
A paper on their work was presented at the 8th International Conference on Structural Health Monitoring of Intelligent Infrastructure in Brisbane, Australia, in December, 2017.
Structural Health Monitoring (SHM) of bridges and heritage buildings are essential to ensure modern rehabilitation techniques and materials continue to perform as expected. SHM systems also play a key role to ensure new buildings perform as expected with respect to energy efficiency and durability.
Their paper focused on the application of advanced sensor networks and data visualization techniques on a building instrumented as a ‘living lab’ located in Winnipeg, Canada.
The BETAC and SMT Research team installed a substantial network of sensors embedded throughout the new STTC.
A total of seven different building envelope types have been instrumented throughout the exterior building envelope as well as the roof and green roof assemblies.
The measurements from these sensors can be compared to controlled tests performed on mock-up test walls in the Dual Environment Test Chamber located in the Centre for Applied Research in Sustainable Infrastructure (CARSI) at Red River College.
Field analysis will be performed in real-time during normal building occupancy throughout the temperature extremes inherent to Winnipeg.

CANCELLED: This workshop has been cancelled due to an unforeseen scheduling conflict with the instructor, and due to low enrolment.
Join expert Manfred Kehrer for a two-day workshop this February, 2018, hosted by Red River College’s Building Envelope & Technology Access Centre (BETAC).

The workshop also focused on the setup and use of blower door equipment, and finished with a full live test of the CARSI building at Red River College, which incorporates diagnostic tools and analysis/reporting of the test data.
Increasing air tightness in a building is now widely recognized as one of the most influential factors affecting the building’s performance in terms of energy use, comfort, indoor air quality, durability and even noise transmission.
Even though airtightness testing of residential houses is quite common, airtightness testing of commercial buildings is only now starting to grow.
Testing equipment is now evolving to measure a larger range of commercial building types; however, since this type of testing is still relatively new to the United States and Canada, there remains very few qualified personnel able to perform these tests to specific standards.
This project focuses on developing cost-effective systems for the implementation of thermally broken concrete slabs for residential mid/high-rise construction.
Traditionally, concrete balconies in mid/high-rise residential buildings are designed as an extension to the floor slab, constructed as a one or two-way reinforced concrete slab cantilevered out past the building’s exterior wall.
Without a thermal break, the balcony easily conducts heat, causing a significant amount of heat loss in the winter, leaving the floor slab and window-wall assembly considerably cooler than the interior temperature, and resulting in condensation.
If not properly controlled, materials eventually start to degrade, reducing the integrity and safety of the structure, and even compromising the indoor air quality from mold growth.
The first phase of this project started in June, 2016, and is due to complete in August, 2017. The completion of phase two is to be determined.
The objective of this project is to investigate and assess the energy efficiency, effectiveness, and performance of vertical, sloped and horizontal DWHR systems for MURB applications. BETAC will be working with Gary Proskiw, Manitoba Hydro, and Manitoba Housing on this project.
Drain-water heat recovery (DWHR) systems recover heat from a building’s wastewater and use it to preheat the fresh incoming water, thereby reducing the overall domestic hot water (DHW) load.
All new Part 9 (residential) construction in Manitoba, as part of the province’s review of Section 9.36 of the National Building Code (other than for houses with slab-on-grade or crawl space foundations), now require a DWHR system. Their introduction into mid/high-rise multi-unit residential buildings (MURBs) has been extremely limited.
The majority of information and testing available for DWHR performance was developed for vertical installations. However, the accessible portions of the drain lines in MURBs are predominately horizontal or sloped at 45°.
For this project, BETAC is working with Manitoba Housing on three case studies for three sets of “twin MURBs” (pairs of multi-unit residential buildings that have identical size, floor area and floor plans) located in Winnipeg, Manitoba.
One building from each pairing has undergone an extensive building retrofit and the other building pairing remains in its original condition.
These case studies will document the pre- and post- retrofit energy performance of the buildings, as well as review each set of buildings to identify the extent of the renovations to each building, and their associated timelines.
