Sefaira

        I came across this tool through a Rahul Shah's Blog. It looks quite interesting BIM world. This is cloud base energy analysis tool.

       Sefaira Concept enables architects and project teams to create better performing buildings with a powerful web-based sustainability analysis platform. It performs whole-building analysis of energy, water, carbon, and renewable energy potential, while an intuitive interface allows for fast, iterative exploration of design options.

         Concept allows you to combine creativity and analytic insight to design buildings that are both elegant and highly sustainable.

          Sharing below some quick pin points of application. All these are taken from Sefira site.

Rapid energy modeling
Get rapid feedback on whole-building energy use, carbon emissions, and utility costs


Integrated water analysis
Quickly investigate measures for water reduction, graywater reuse, and rainwater capture



Import building geometry
Create models in SketchUp, then upload them directly into Concept
