Glazing database - effect of adding blind on G value and Shading co-efficient - CIBSE Gainhttps://communities.bentley.com/products/building/performance/f/hevacomp-forum/130336/glazing-database---effect-of-adding-blind-on-g-value-and-shading-co-efficient---cibse-gainI have created a new glazing type for use in the CIBSE Gain tool. Now I want to create a second glazing type which includes a blind. I have used the calculations in the CIBSE solar gain factor guide and modified all of the solar gain factors accordinglyen-USTelligent Community 12RE: Glazing database - effect of adding blind on G value and Shading co-efficient - CIBSE Gainhttps://communities.bentley.com/thread/397598?ContentTypeID=1Fri, 06 Jan 2017 13:31:01 GMT6dad98f5-dbc9-4c4d-a9ba-e9da8dc6aa8e:14109636-955c-4961-b548-59850e0ded22Shane Regan<p>Hi Michael,</p> <p>It is my understanding that the Uvalue and light Transmittance figures will not be affected by the blind, while the Shading Coefficient and SHGC would definitely be impacted. However the glazing manufacturer will need to confirm this for you&nbsp;- they should be able to provide this data for both with and without blinds.</p> <p>Our Glazing Data article <a href="/products/building/performance/w/building_performance__wiki/10013.glazing-data">here </a>may also be of use to you.</p><div style="clear:both;"></div>
