Success Stories

Draft Control

In the Library, Building 305, there is a suite of offices located on the 3rd Floor facing west that were fitted in the original construction with single pane windows. The office staff experienced significant draft conditions partly due to the window technology employed. This year, Facilities Services and Campus Development Department was allocated with funds for energy conservation, with a recommendation from a consultant to apply solar film to the aforementioned windows, to reduce draft conditions. Instead, though, FSCD elected to replace the windows with thermopane, low-emissivity glass, in order to more certainly reduce the draft conditions. In the photo below, you will see the installation, which although appears to be a standard window installation, has helped to reduce drafts for the staff in the offices. The low-emissivity rating is in reference to the characteristic of the glass assembly to control the transmittance of infra-red radiation through the glass panels. Hence, solar radiation is reflected to the outdoors, and internal heat is reflected to the indoors! Reports from staff in the building indicate that the installation has improved conditions for them.

Solar Gain Control

Building 100: As this building consists of a group of factory-relocatable-modular structures, it is highly susceptible to solar gain and to interior heat loss, through the many windows. An inexpensive solution was recommended to VIU in the Energy Audit of 2006, to simply apply "low emissivity" solar film to the windows, in order to improve their performance. "Low emissivity" refers to a property of the film to reflect infra-red radiation, and the product is designed to reflect the infra-red in both directions. Thus, solar gain is reflected to the out doors, while interior heat is reflected back to the interior, reducing losses, and reducing cooling loads. The installation was completed in early March, so it may be a bit early for testimonials, but we are hopeful that with this installation, comfort conditions will be enhanced for the occupants, and energy will be saved as more of the heat produced inside the building will stay inside, and less of the solar heat will need to be cooled by our mechanical cooling system. And we think the gold tint looks good against the VIU green too!

Building 100 Solar Film

Building 150: In a similar application to that of Building 100, we ordered the installation of the "low emissivity" solar film to the South-facing windows of Building 150 because the two classrooms of the Automotive Repair Shop are highly susceptible to solar gain.
