Hello!

I'm curious what other firms like to use to run site-specific sun path and wind path analysises that is relatively intuitive to use and generates good graphics. We have used the climate consultant software for wind roses which is free and simple. We've also used sefaira but we're hoping to crowd source more resources. We purchased... Read more

Nothing exciting like embodied carbon or EPDs... but I'm interested in some real talk on the actual performance of low-flow fixtures.  

We continue to encounter pushback on water-saving fixtures for concerns of ongoing performance. I'd love to have a dialog in this group because I find it hard to believe these challenges can't be... Read more

Does anyone have a good recommendation for getting started with energy modeling with future weather files? We use a combination of Sefaira and Climate Studio, but open to suggestions. Even just links on how to approach this for making good recommendations to clients. Thanks in advance.

Have any of you heard of anyone ever using phase change material (PCM) "movable partitions" as a resiliency strategy to mitigate indoor overheating during a heat wave in passive buildings? You'd keep them stored in a basement or cool room, and deploy them into habitable spaces during the heat wave to keep the space cooler than the exterior... Read more

Hi,

Has anyone been asked by a client to track welding rods on any projects? We were recently asked to do this. I was asked why the client would ask us to do this. I don't know if it has to do w/ "real property" and is a property tax-related reason, or if it is an environmental/sustainable reason. There is piping associated with the... Read more
