FRSI Calculations
Facade reflective solar index (FRSI) calculations where overheating and solar gain drive retrofit design choices on exposed elevations.
FRSI analysis to inform shading, glazing and ventilation strategies on retrofit projects where solar exposure affects comfort risk.
- Evidence for design decisions tied to elevation and orientation
- Supports overheating dialogue alongside ventilation strategy
- Documentation suitable for design-stage reviews
