    Thunder Bay Saves with Energy & Engagement


    Spence Court is an electrically heated 163-unit building built in 1973, and owned by Thunder Bay District Social Services Administration (TBDSSAB). In 2016, through the Social Housing Apartment Retrofit Program (SHARP), TBDSSAB implemented several natural gas retrofits at Spence Court. These included the replacement of 3 high-efficiency domestic hot water boilers, 3 hot water storage tanks, and a high-efficiency make-up air unit. Through the SHARP retrofits, TBDSSAB was able to obtain over $100,000 in Union Gas incentives and achieve an estimated annual average reduction in gas use of 38%.

    The energy retrofits were enhanced with HSC’s Community Champions programming – a series of four unique energy conservation workshops tailored to residents at Spence Court. Retrofits and engagement are proving to be a winning combination.  Check out the full case study!

    UMP Users: Your Q1 2019 Reports Are Ready!

    Good news, UMP users! Your latest Q1 2019 UMP Reports and updated dashboards are now available in our online UMP system. There are two sets of reports to choose from:

    • Year-over-year Use Comparison: one report each for gas, electricity, and water, comparing your use over multiple years.
    • Annual Utility Use Summary: a 12-month summary of your energy use and utility costs in pie-charts and data tables.

    Log-in to UMP and go to “Reports–Reports Shared With Me” to download all four reports to PDF.

    And don’t forget, you can quickly view your energy data in our simple dashboards. The dashboards provide a handy snapshot of your energy performance across multiple months and years.

    Not sure how to download your reports? Follow these step-by-step instructions or contact

    UMP Summer Training Webinars

    Summer is a great time to improve your understanding of your buildings’ energy performance.  Register for one of our upcoming webinars to get to know the UMP system better and build your energy knowledge.webinars

    How to Understand Your Energy Data — Monday, July 22, 11:00 am – 12:00 pm

    This webinar builds on what you learned in the introductory UMP webinar to give you a deeper understanding of your data. We will look at specific examples, learn to spot issues and anomalies, and discuss how to use the data to report to your boards. This webinar is for all user skill levels and will focus on the Dashboards and Reports modules.

    Energy Project Tracking — Tuesday, July 30, 11:00 am – 12:00 pm

    UMP includes a project tracking tool that allows users to view the progress of energy efficiency improvements at a high level. This webinar will provide an introduction to this basic tool including its location, how to use it, and how to review results. This webinar is for any user skill level; familiarity with energy concepts is helpful but not required.

    If you’d like to suggest a topic for an upcoming webinar or would like to schedule a one-on-one review of your UMP data with HSC staff, contact

    Thermal Bridges — A Path to Energy Waste

    The evidence is continuing to grow – thermal bridging can have a big impact on your building’s energy use and its ability to withstand outdoor temperature changes. Knowing what thermal bridging is and how to prevent it can reduce your building’s heating and cooling energy use.

    What is Thermal Bridging?

    Heat will always move along the path of least resistance. Thermal bridging happens when a material transfers heat at a faster rate than surrounding components. For instance, we use insulation in our building envelopes to help stop heat loss in winter and heat gain in summer. But insulation is often installed in parallel with more conductive materials, like wood, metal, and concrete. These materials conduct heat more readily than the insulation they surround and act as “bridges” for heat to flow across.

    Where do Thermal Bridges occur?

    Thermal bridges typically occur at breaks in insulation in walls, roofs, and other building envelope components. They often occur at interaction points or “interfaces” between different components, such as slabs, parapets, and glazing, or components in a wall assembly, as well as corners, wall intersections, cladding attachments, and structural beams. They can also happen where insulation is lacking.

    Why do Thermal Bridges matter?


    Thermal bridging greatly affects the thermal performance of the building envelope. When thermal bridges allow heat to bypass the insulation layer, the effectiveness of the insulation is reduced so that more energy is needed to replace the lost heat in winter and cool a building in summer. Thermal bridges can also increase the risk of condensation and mold and reduce resident comfort.



    How is Thermal Bridging prevented?

    You may think that adding more insulation might reduce the impact of the thermal bridging, but this is usually not the case. This is because thermal bridges allow heat to bypass the insulation.

    To prevent thermal bridging, thermal breaks are needed. Usually a thermal break is comprised of a material that does not conduct heat well and is placed in an assembly between more conductive materials. For example, in aluminum windows, rigid polyurethane, which has low heat conductivity, can be inserted as a barrier between the more heat-conductive metal inner and outer frames.


    Similarly, inserting structural thermal breaks between the balcony and floor slab will also reduce heat flow between a building’s interior and exterior. A structural thermal break is load-bearing as well, and will help maintain structural integrity by transferring loads between the balcony and floor.

    In new buildings, thermal breaks should be included in the design to prevent thermal bridging. For example, wall and roof assemblies, windows, and basement slabs should be designed to minimize heat transfer. Techniques as simple as sealing building envelope penetrations with foam, caulking, and tape can dramatically improve air tightness. In fact, certain energy efficiency building standards, such as LEED and Passive House, emphasize  the importance of addressing thermal bridging as part of the overall quality of the design. Costs to address thermal bridging are minimal when considered at the design stage of a new building.

    Thermal bridges are likely numerous in existing buildings, especially those with balconies and single-glazed, metal window frames. Although addressing thermal bridging in existing buildings can be costly and often cost prohibitive, window replacements present an ideal opportunity to address a key area for thermal bridging. Replacing old windows with triple-pane, vinyl frame windows or at least metal frame with thermal breaks, will help to reduce heat transfer in and out of windows each season. For information on choosing windows, see our article in the Q1 2019 issue of Energy Matters. Installing insulating cladding can also help reduce thermal bridging in multi-residential buildings, while improving insulation can mitigate them in houses.

    Taking even the smallest steps to reduce thermal bridging can have big impacts on your energy consumption. Whether dealing with a new building or improving an existing structure, consider what steps you can take to prevent thermal bridging from negatively impacting your energy costs and resident comfort.

    Catching the COCHI-OPHI Opportunity

    In late April, the Governments of Ontario and Canada announced the Canada-Ontario Community Housing Initiative (COCHI) and Ontario Priorities Housing Initiative (OPHI) as part of the bilateral agreement under the National Housing Strategy. While COCHI is focused exclusively on funding projects that protect, regenerate and expand social housing, OPHI is broader in its focus, modelled after the old Investment in Affordable Housing program.
