The proposed product has been used successfully in healthcare, and switching to it will save the project almost $1million, which is no small amount when the project is over budget and 7-figure cost...

Hi - I'm wondering if you have recommendations for a web/mobile app for occupants to self-assess comfort at regular intervals. I've downloaded comfy, but it wants to actually DO something about thermal discomfort by alerting discomfort and connecting, I believe, to the BMS. We just want to collect information at this point.

We want to... Read more

Hello all,

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
