Benchmark by Region


Starting January 1st, 2014, California law now requires disclosure of an energy benchmark rating during a whole building financial transaction. Whole building financial transactions include: a sale, a lease and a refinance.


October 2007 the Governor signed into law AB 1103 mandating energy benchmarking and energy disclosure for non-residential buildings. The law stipulates that a building owner disclose benchmarking data and ratings for his entire building for the most recent 12-month period to a prospective buyer, lessee or lender. Building owners or their authorized representatives must use the EPA-approved EnergyStar™ Portfolio Manager (ESPM) on-line tool by entering at least the most recent 12 months of energy consumption and other building data such as hours of operation, occupancy, building size and other data that affect energy consumption.

Date Event
January 1, 2014 Non-residential buildings greater than 10,000 square feet are required to benchmark & disclose energy performance
July 1, 2016 Non-residential buildings greater than 5,000 square feet are required to benchmark & disclose energy performance

  1. Eligible (**) buildings that qualify for ESPM national energy performance rating must disclose it when the Regulations are triggered by a building sale, lease or refinancing. If a building achieves a rating of 75 or higher the owner may apply for an ENERGYSTAR™ Plaque to be exhibited publicly provided the data was certified by a professional engineer.
  2. Buildings ineligible for ESPM energy performance rating must disclose energy use intensity level (kBTU/sq. ft. per year) when the Regulations are triggered.

**Buildings eligible for ESPM energy performance percentile (1 – 100) rating are: banks, courthouses, data centers, dormitories, hospitals, hotels, Houses of Worship, K-12 schools, medical offices, office buildings, retail stores, supermarkets, warehouses, senior care facilities, wastewater treatment plants. The rating compares a given building against similar buildings within its class, adjusting for climate but not for the age of the building.

In the event that a building has a tenant that is billed directly by the electric/gas utility, the utility will need the tenant’s written authorization to release its energy consumption data.
