I'm hoping for some help answering the question of whether buildings/communities should pursue net-zero energy on site versus investing in new renewable energy (i.e. through the electric utility) that can be built at a more efficient scale elsewhere in the state. Our utility is asking us this question as we are working through how to get the... Read more

I was recently asked about potentially specifying concrete with wood nanoparticles and concrete with biochar as a way to further lower the embodied carbon and to increase concrete strength.  These approaches are something I know nothing about, and wondering if anyone in this group has any experience and/or observations that might be relevant to...

Does adding solar panels reduce a building's EUI?

Existing operational use of a building is 80 kBtu/sf/year. When we add solar, it will change the source of energy but does not change the usage.

My understanding is that the EUI does not change, but it would be good to hear from others.

It's energy consumption at the point... Read more
