(#590)SHGC for complex shading design


A residential project has a very complex shading design with a mix of horizontal and vertical shading devices. It is very difficult to calculate adjusted SHGC for each and every window. However, it has been ensured that the selected DGU has a SHGC value of 0.37 which is lower than the threshold of 0.45. Is it still required to submit the adjusted SHGC calculation in this case for both pre-certification and certification documentation?


In this case adjusted SHGC calculation is not required since glass SHGC is less than the defined threshold of 0.45 for residential building typology.
