Montgomery County building energy benchmarking
Every building disclosed under Benchmarking Law (Bill 2-14) / BEPS (Bill 16-21) (Commercial Building Energy Benchmarking), graded and cross-linked. Montgomery County's BEPS (Bill 16-21) sets declining site-EUI performance standards for covered buildings, phasing in from 2025 with compliance obligations for buildings above interim targets.

No coordinates in this source
Montgomery County's disclosure file publishes no latitude/longitude, so its buildings aren't mappable yet — pages are addressed by street address instead. We'll light the map up when the source (or a geocoding pass) provides coordinates.
