HI All,

I am curious if others are using THERM in-house for your envelope design?

We usually use our building envelope/curtain wall consultants (Boston - so mostly RWDI and Heintjes) but our teams are finding that they need the information faster than our consultants can provide, they are backlogged, or we have some curtain wall... Read more

I think they look great - thanks to BuildingGreen for setting this up!  A few comments/questions:

Hi - I'm wondering if you have recommendations for a web/mobile app for occupants to self-assess comfort at regular intervals.

Hello all,

Does anybody know of a substitute for Ecotect's solar tool? I use it to very quickly test shade options and I love how I can easily test horizontal and vertical elements, tilting and rotating them. I can have a window with the façade on one side and the sun path with the shadow mask on the other side. It is easy to use and... Read more
