The Multifamily Sector: Quick Facts
• More than 15 million occupied rental units
• $22 billion in energy expenditures
• 100 million tons of carbon emissions
• Median age of multifamily buildings: 36 years
Soaring utilities costs have added to affordability
pressures since 2000.

Building benchmarking yields energy and water savings
EPA analysis shows 7% energy savings from benchmarking

Tracking water use leads to detection of leaks and savings
Even the most aggressive codes and incentive programs have only managed to flatten per capita energy usage.
U.S. Benchmarking Policy Landscape
In large cities with good public transportation, buildings typically account for 70% or more of CO2 emissions and energy usage.

Commercial Building Benchmarking Policy Elements
Early Findings from Energy Benchmarking in New York City
.
Early Findings from Energy Benchmarking in New York City
Report for the California Public Utility Commission:
Utility-led benchmarking programs yielding substantial energy savings
April 2012
• 62% took energy management actions
• 84% planned or implemented energy efficiency improvements
• 81% link improvements to utility efficiency programs
• 82% said utility training had been sufficient to benchmark buildings on their own
Of those who benchmarked:
Building owners often can’t get utility data for their buildings
Barriers:•Separately-metered tenants
•Lack of clear procedures
•Utility policies and state privacy laws
•Lack of standardization
