I am trying to estimate the current performance of a building but it appears the only way to see what the GHG Emissions Score, Source Energy Score, and Energy Performance Score is to fill out

Hi All, can anyone explain the meaning of "the lamps are adequately shielded" in the Light Pollution Reduction Criteria?

In this credit, How can I prove that my  purchased material has compile with Embodied Carbon/LCA Action Plan or other impact reductions .

When modeling district cooling and heating systems using Option 1, Path 1: ASHRAE 90.1-2010 Appendix G, the LEED Reference Guide instructs the following: "If tariffs or rates are not available from

Hi,

For the prerequisite requirement to add R-19 insulation to floor / slab under energystar, is it required on every floor?

We are having a tough time getting the costs from our subs. The subs says that the cost is bundled with other material and they can't break it up.

Hi LEED experts, in LEED v4.1, NC projects with more than 50% unregulated energy cost can apply CS point thresholds to count points. I would like to ask if LEED v4 also applies 

Instead of demolition or deconstruction, this project will move an entire building across the street to another site on the campus.

LEED v4.1 references ASTM standard E2813 Standard Practice for Building Enclosure Commissioning regarding BECx requirements.
