Sefaira, thermal modelling add-on for SketchUp. Any good?

[Dreadnaught]

I wonder does anyone know anything about this unpronounceable software, Sefaira, an add-on for Sketchup for thermal modelling launched in 2013.

• Smart Modelling
• Envelope Design
• Daylighting Design
• HVAC Design

 

It seems to have been a startup in 2009, launched its product in 2013, and then bought by Trimble, the makers of SketchUp. Some of the web pages are broken which suggests that the acquisition might be in-progress.

 

Seems to fall under the heading "BIM".

 

My architect asked, knowing I was a BuildHub-er.
