After reviewing BP language today with internal staff, we realized we'll need to add a glossary to explain industry jargon and technical terms that might not be widely used. I'd like to consolidate those terms onto one web page, a glossary. This probably should be on the list with the best practices, and it will need its own page. Thanks!

If anyone else has gotten confused going between parts-per-million and percentages (parts per hundred!) for material reporting here's a little infographic that might help. Feel free to use or improve!

I was shocked to see this new research. Bad news is that acrylic paints are causing 58% of the microplastics pollution in our ocean. Yes, they are plastic. A recent study by Environmental Action, a Swiss-based scientific research firm, shows us that acrylic paint's role in plastic pollution is much greater than most of us realize. The good news...

Hello friends,

We are embarking on calculations to quantify avoided embodied carbon from converting an old school building into a multifamily project and I wanted to vet our methodology with you.

Hi,

I selected a new background photo for the home page (the previous one was the same as on LEEDuser.com). I found the photo here:

I needed to find something low-contrast that wouldn't compete with the text. I initially tried some of the stock photos... Read more

Does anyone know of a source for finding the operational solid waste generated by typical building/use types (weight/sf)? I couldn't find anything on LEED, True, or EPA. I found this table but isn't by sq ft for many of hte uses. Waste Generated by Industry and Building Type (wastecare.com)
