Qualiverre worked with an accredited simulation laboratory to model a generic building in order to accurately evaluate the performance of Enthermal™ within a context specific to the province of Quebec.

These simulations are based on local data — climate conditions, energy consumption patterns, and building typologies — allowing the real impact of vacuum insulated glazing on energy efficiency to be quantified in scenarios representative of Quebec’s building stock.

Study Objectives: Evaluation of the energy savings potential associated with replacing existing glazing systems with vacuum insulated glazing (VIG), compared to double and triple glazing.

Generic Building Description: Building geometry, office occupancy type, window-to-wall ratio, internal loads, and occupancy profiles representative of the Canadian building stock.

Window-to-Wall Ratio (WWR): Thermal performance of opaque assemblies and fenestration systems (glazing + framing).

Comparative Glazing Analysis: Comparison between double glazing, triple glazing, and vacuum insulated glazing (U-values and SHGC).

Energy Simulation Methodology: Simulation tools used (WINDOW and eQuest), standard assumptions, and modeled scenarios.

Energy Model Validation: Comparison of simulation results against reference data to ensure model accuracy and representativeness.

Detailed Energy Results: Total annual energy consumption, heating loads, and cooling loads for each scenario.

Potential Energy Savings: Relative performance gains achieved with VIG compared to existing double glazing and triple glazing systems.

Thermal Comfort Impacts: Effect of glazing systems on interior surface temperatures and occupant comfort.

Conclusion – Key Findings of the Study

The energy simulations conducted demonstrate that vacuum insulated glazing (VIG) enables significant reductions in the energy consumption of a representative office building in a Canadian climate. Compared to existing double glazing, VIG reduces total energy consumption by up to approximately 20% and heating demand by nearly 45%, while consistently outperforming triple glazing systems. These results confirm the strong potential of VIG technology to improve both energy efficiency and thermal comfort in commercial buildings, particularly in renovation projects and cold-climate building design.
