Is there a list of which number corresponds with each Best Practice? E.g. "03 Energy Audit & Planning."

I was sitting in on the USGBC's monthly Advocacy call this afternoon and heard about a state-local policy proposal to use property tax incentive for GHG reductions.  Through a state-local partnership, owners of existing residential and commercial buildings who invest in qualifying outcome-based improvements would receive a property tax...

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

Hello all,

We are having a mini office debate on fiberglass vs aluminum windows for use in schools (k-12) in Massachusetts. In the past we have always used aluminum windows on our schools, for durability. However, their performance is not as great as other products that are up and coming on the market. There is some hesitation to switch... Read more

Does anyone have experience pursing SITES certification on an essentially a zero-lot line project?

We are required to achieve silver certification, but the project scope/phasing recently changed and the entire site/parking area was eliminated and we no longer have a green roof. It still appears we can meet silver certification as so few... Read more
