I'm curious who in this group has used ASHRAE Standard 209-2018, Energy Simulation Aided Design for Buildings except Low Rise Residential Buildings?

We've used it internally (minimally) as a reference to help better communicate the goals and activities involved with energy modeling at various phases of design. But it seems like there's... Read more

Carpet is comfortable, offers good sound control, and offers great aesthetic options. But it is typically made from petrochemicals, and carpet and its adhesives can offgas VOCs. It is also a challenge to recycle, increasing the chances that it will be incinerated or disposed of in a landfill. Broadloom carpet cannot be readily repaired if... 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

You’ve probably heard that wood products are carbon neutral. You might also have heard that timber harvesting causes immense carbon emissions.

Which is it?

Could it be both?

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 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
