Considerations for Reference Shading NECB 2020
Section 8.4.3.1.(7 & 8) (Proposed Building)
States that:
- The energy model calculations shall not include manually operated fenestration shading devices, such as blinds or shades
- The energy model calculations shall include permanent fenestration shading devices, such as fins, overhangs, and light shelves
Section 8.4.4.3.(4 & 5) (Reference Building)
States that:
- Permanent fenestration shading devices and projections shall not be modelled in the reference building (this is performed automatically by the software)
- If the proposed building is modeled with exterior shading provided by a nearby structure or building, the reference building shall also be modeled as such (performed automatically by the software)
