Are you still using shading multipliers from the National Construction Code 2019 for J1.5 Calculation of U-Value and solar admittance? Can such a simple set of numbers represent shading ☂️ in reality? The simple answer is no.
Last week we pushed our new Simulated Shading Multipliers feature. When activated, instead of referencing inaccurate shading multipliers from the NCC 2019, it compares each window 🪟 as completely unshaded, to windows affected by attached shading, building self-shading, and surrounding structures.
The result? Each window is assigned a unique shading coefficient, replacing the coefficient selected from the DTS shading tables ❌ while enabling a more representative design process for NCC compliance.
Let's design our buildings and not tick boxes!
