Glazing Performance & SHGC Calculations
Fenestration and glazing compliance assessment including Solar Heat Gain Coefficient calculations, shading coefficient analysis, and combined glazing-shading system performance evaluation.
Module Overview
Solar Heat Gain Coefficient (SHGC) is a critical parameter in building energy performance and SANS compliance. This module teaches you to calculate and specify combined glazing-shading SHGC values, interpret glazing performance data, and evaluate how different shading systems modify the overall fenestration performance. You will learn to work with glazing manufacturers' data and shading performance specifications to achieve target SHGC values.
Learning Outcomes
- Identify the relationship between SHGC, shading coefficient, and overall fenestration performance Calculate combined glazing-shading SHGC values using manufacturer performance data Apply SHGC targets to specify appropriate shading solutions for different facade orientations Evaluate glazing and shading combinations to optimise the balance between heat gain and daylight Specify glazing-shading systems that meet SANS compliance requirements
