WELL and Fitwel have emerged as the two leading wellness rating systems,... Read more

Hello! Does anyone know of any general contractors who produce a CSR? Is anyone aware of any general contractors who have an ESG rating? If so, what company is being utilized (i.e. EcoVadis) to get the ESG rating?  

Does anyone know where one can locate weather files (EPW) that has predicted future data for climate change?

Thanks in advance.

Hey all,

Thanks to everyone who joined today's peer network webinar - it was great to share what our working group has been developing in the last year. This group gathered to work through a series of decision-making trees to publish some kind of relatively repeatable guidance for how to advance this conversation with a variety of owners...

The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

Hi all - I heard from sevearl of you at Greenbuild that you have learned from and perhaps even shared the Path To Zero Carbon series internally at your firms and externally. As I mentioned at Greenbuild, we are attempting to hand off the series to a non-profit, with the idea that groups of experts (including many of you, I hope!) will provide... Read more

Hey there SDLs!

We're having a debate in our firm about whether we're at a tipping point to hire an in-house energy modeler - someone capable of doing an MEP-caliber energy model inside a design firm. I know some you have in-house energy modelers on staff and I'd love to hear your experiences:

- How did you know your firm was at a... Read more

Has anyone used a commercial heat pump water heater for a large protect?  I have found a few manufacturers for this technology, but want to make sure this is a viable and cost approach to electrical eliminate gas on a path to all electric.

Hi everyone - in doing a carbon footprint for our firm, does anyone know if buildings that we design as Architects considered scope 3 emissions, or are they beyond the boundary of emissions? LMN's buildings, despite best efforts, are cumulatively multiple orders of magnitude above our scope 1 and 2 emissions. We have never included these... Read more

Under a high carbon scenario, most of North America will be 2 degrees C hotter by 2050. Meantime, we're designing buildings that will still be around in 2050, to codes that don't yet factor in chronic risks associated with climate change. I want to explain these risks to my colleagues; I'm hoping some of our green gurus can help answer the... Read more

Looking for an example or case study for a building utilizing a radiant heating/cooling in climate zone 4a. General use type is office with some public assembly spaces, total of 85,000 sf.

As usual, everyone, especially mechanical engineer, is terrified by the thought of "condensation." So far, I read a DGWW case study, "Energy... Read more
