We have an MEP engineer that is calculating peak loads at about 6 times passive house levels on a large commercial building that is at or near passive house levels of insulation and air infiltration. We suspect one reason is that he is figuring a 50% efficiency level for the ERV. We are showing him ERV systems with 80-90% efficiency, but they... Read more

Hi All,

Has anyone dug into ASHRAE 2016 as part of the new v4.1 requirements or as codes start to adopt it? I recently presented on this and thought I should check my math to make sure I'm understanding and communicating this correctly.

My understanding is that there is a new reference baseline, that is essentially the ASHRAE 2004... Read more

Thanks to SERA especially David, Kira and Clark for an inspirational conversation with Paul Hawken about his latest book. I know I needed a positive perspective! Then I found this great "Regeneration Anthem" song and had to share.

Happy Fall to all.

All,

I've probably spoken to a few of you over the phone, but I wanted to make sure all of you know that we are hosting a 4 part webinar series on our Tally LCA software, kicking off tomorrow 10/10. We just released the new of Tally version and ended up doing far more development work than initially anticipated, in no small part due to... Read more

We are having trouble sourcing a LEED compliant wallcovering adhesive. We specified Roman Pro-880 which is low VOC but doesn't have sufficient back up for TVOCs. Have you had success with other products?

Composting toilets convert human waste into nutrient-rich fertilizer for nonfood plants, rather than mixing the waste with potable water and flushing it down the drain. They can also save infrastructure costs and minimize the burden on wastewater systems.

They’re not for every project, but they do warrant consideration. Composting... Read more

Is anyone willing to help us troubleshoot or share lessons learned? We're running into a few errors and wonder if our Revit models and workflow are the issue, or if we need to be doing something...

It may take hundreds or thousands of years to return to pre-industrial-age levels of atmospheric carbon dioxide, but the loss of animal and plant species that is occurring today is, practically speaking, irreversible. It will take millions of years for evolution to fill the ecological niches being vacated by extinctions and restore healthy... Read more
