Wondering if we can have a dialog on HVAC load calculation software... we are currently still using Trane Trace 700, but with the future migration to Trace 3D+ coming are looking into other options.

I am working on a new community development in St. Paul that is striving to achieve net-zero energy. We are able to get there mathematically by using the extra generation on light industrial rooftops to offset medium-density housing energy use (all buildings are anticipated to have different, private owners). However, this puts us over... Read more
