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

Hi SCL,

I realize that there are already a couple of threads on this topic, but I didn't see anything from the past year.  We have been trying (unsuccessfully) to work with large rental companies to request jobsite trailers that are at a minimum energy efficient, and ideally solar/battery ready and/or built to passive house or similar...

Hey team,

I'll go look to see who's in the MEP group, but does anyone in this circle have a northern California design engineer for institutional work that they'd particularly recommend? A group of folks we're engaged with is apparently having difficulty identifying a California-based MEP that everyone universally likes for high-... Read more

Hey Gurus:

I have a client who is interested in reporting to their superiors on the status on energy codes in different states across the US. They are hoping to find some kind of summary that might show relative costs for HVAC systems under the various energy codes in effect across states. They are also interested in data that is...

We're wrapping up a multi year project that went through multiple design changes, leaving us with a ton of material samples.  Does anyone know of a good place we could donate these samples to, to keep them out of the landfill.  I'm in the greater Seattle area.  Thank you for any suggestions.

I am now embarking on the home page design, but before I get started I need input on what you'd like to have there. The style tiles/tidbits provided by Southface includes a home page mockup that's very similar to LEEDuser, which is fine with me, but I don't want to implement it and then find out you want something radically different.

I... Read more
