Ahead of our webinar in early April (on 5 Tips for Smarter Facade Design), we’ve been playing around with combining the use of FenestraPro with Autodesk’s Insight 360 plugin for Revit. Insight 360 is a solar analysis tool for Revit that allows users to understand some of the environmental considerations on facades and buildings and where the problematic areas occur.
Currently, solar analysis in Revit assumes glazing to be 100% transparent. Revit users can then deploy FenestraPro for Revit to get more granular detail on glazing specification.
By mapping solar insolation, designers start getting a good understanding of where the problem areas will occur and where attention is required. For example, to avoid overheating the space next to the building below, served by curtain wall assembly A, the facade will require either:
- A sunshade, to match other curtain walls;
- A revised specification, with higher performing glazing;
- A frit.
When using FenestraPro to drill down into curtain wall assemblies, users can understand how to optimise our glazing selection to reduce solar heat gains in the space without sacrificing daylighting, or in this case, thermal performance. We can see instantly the following:
- Low E Triple Glazing: R-Value for the Curtain Wall is good, but internal heat gains are poor;
- Reflective Single Glazing: R-Value for the Curtain Wall is poor, but internal heat gains are good;
- Reflective Double Glazing: R-Value for the Curtain Wall is good, and internal heat gains are good.
Using the snapshots feature of FenestraPro, we can compare and demonstrate the effects of the different glazing specifications.
