Hoping to collect some advice on this. Our current hospitality project's low-sloped rooftop (approx. dimensions 13.8mx20.0m) is underneath a shading layer (approx. dimensions 18.7mx 20.0m). The shading material is a lightweight mesh material / perforated tensile fabric and serves a primarily as an aesthetic and dappled shade provider for the external terrace spaces. The tensile mesh material will be a sandy / beige colour while the rooftop will be a beige / light colour (SRI values from manufacturers still pending).
When calculating the rooftop areas and collecting the corresponding SRI values, can i ignore the shading material and use the actual structural roof top material only or will the shading material need to also comply with the initial SRI of 82?
Thanks for your help!
