Hi all,

Here's a good follow up to Maria's steel question on Monday.  We have a Midwest project that unfortunately (from a carbon perspective) is required to use a traditional, thick precast facade.  We’re working with the contractor and potential future (not yet bid out) fabricators to determine an appropriate % of pozzolanic material...

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).

Hi all,

We have an institutional client who has tired of LEED and is instead putting forth EarthCraft Light Commerical as a replacement certification (they like the performance verification & lower cost that ECLC provides).  Has anyone used ECLC? It seemed an odd choice but wanted to hear from others on their experiences. The... Read more

However, their performance is not as great as other products that are up and coming on the market. There is some hesitation to switch... Read more

Our guys have started talking about how the built enviroment can address infection transmission in public spaces - places like lobbies and waiting rooms, particularly in applications where people queue - theaters, airport gates, amusment parks, etc.  In the specific case of Covid-19, we know the microbe can be transmitted three ways:  fomite (...

The sheer number of building product certifications and labels is overwhelming, and even those experienced with green labels can get exhausted trying to figure out which are relevant and which aren’t.

The confusion in the market over green labels can complicate efforts of both manufacturers and design professionals... Read more

Curious what people's 'best' experiences or recommendations are for load calculations and energy modeling regarding electrochromic glazing... hoping I can lean on others as it's just now becoming more of a talking point in our market here in Omaha.
