Assessor use NatHERS Rating as a means to achieve compliance with energy efficiency provisions of the NCC. However, using VURB method as a means of compliance, has the following benefits:
- With VURB, your building is compared to your building! not with a Benchmark or a preset of area-adjusted heating and cooling demand. Therefore, VURB allows a comparison with a reference building having the same geometry and features.
- With VURB, the modelling software calculates an hourly energy demand using a weather-file. Also, you will be able to assess solar gain in an hourly manner. Therefore, the software captures the physics of solar heat gain in building materials such as windows and also the impact of thermal mass and shading devices.
- VURB method utilizes a commercial software for energy analysis. Commercial tools have many features like design optimization and parametric study. This features helps to reach a better solution for the compliance of your building.
These benefits generally allows you to have a cost-effective compliance compared to a simple NatHERS rating. Check our past experience for more details.
