Berkeley building energy benchmarking
Every building disclosed under BESO (BMC Chapter 19.81) (Building Energy Saving Ordinance), graded and cross-linked. BESO requires energy assessments and benchmarking for buildings over 15,000 sq ft, with compliance enforced through the city's assessment cycles.

The map
No coordinates in this source
Berkeley'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.
