ENERGY BENCHMARKING Unlocking Efficiencies in New York’s Buildings with Aggregated Whole-Building Data
BACKGROUND ON BENCHMARKING
Building Energy = Majority of NY’s Carbon Pollution ! 40% ! of national CO 2 emissions ! 60% ! of New York State CO 2 emissions ! 75% ! of New York City CO 2 emissions !
What Is Benchmarking? ! Measuring and comparing building energy use over time The foundation of building energy management – you can’t manage what you don’t measure! Typically done with US EPA’s free online tool, ENERGY STAR Portfolio Manager ! Critical for understanding and achieving cost savings and efficiency improvements in New York State buildings !
Benchmarking Targets Large Buildings ! 6% = Half of commercial floor area 5.6 million (commercial buildings nationally)
An Increasing Trend ! 15 cities, 2 states and 1 county with mandatory benchmarking policies 6.6 billion square feet covered by benchmarking policies 35 billion square feet from 400,000 buildings benchmarked in Portfolio Manager That’s more than 6.5 x NYC!

Current Benchmarking Policy in New York ! New York State New York City Benchmarking for state buildings A national leader – Now in its fifth >20,000 square feet (Gov. Cuomo’s year of benchmarking for all Executive Order 88) buildings >50,000 square feet • 2,261 buildings • ~ 15,000 properties and ~ 25,000 • 212 million square feet buildings • 90% of state-building floor area, • More than 2.3 billion square feet energy use and energy cost • ~ 50% of NYC floor area !
Benchmarking Aligns with REV ! REV policy objective: Enhanced customer knowledge and tools for effective total energy bill management Benchmarking empowers customers with access to usage data – building owners are customers at the building scale REV policy objective: Market transformation Benchmarking makes building performance visible in the market , incentivizing increased efficiency and stimulating private sector services REV policy objective: Reduction of carbon emissions Benchmarking helps catalyze efficiency improvements , reducing building energy use and carbon pollution !
Benchmarking Benefits Multiple Stakeholders ! Benchmarking: ! For: ! Provides additional information about buildings and their systems, which can be the basis of future customer engagement Utilities ! Increases demand for energy efficiency programs , helps prioritize efficiency incentives and enables pay-for-performance programs Owners & Enables informed building efficiency Managers investments Makes building performance visible and Tenants, Buyers valuable in the marketplace & Investors Provides novel insights to shape effective Policymakers ! energy and carbon policies

ADVANCING BENCHMARKING IN NEW YORK STATE
Current State of Building Data in New York ! Easier for building owner to benchmark Easier for utilities to identify customers for efficiency improvements 1 building, 1 meter ! Owners need aggregated whole-building data to understand & manage energy use Utilities need aggregated whole-building data to direct efficiency efforts to relevant buildings 1 building, many meters !
Advancing Benchmarking in New York State ! 1. Provide monthly whole-building data statewide Utilities in New York should facilitate by: • Mapping meters to buildings • Providing aggregated whole-building monthly energy use information to all building owners in NYS • On an ongoing (monthly) basis Image source: U.S. DOE, Better Buildings Energy Data Accelerator ! * Note that owners need to add building use characteristics to Portfolio Manager !
Advancing Benchmarking in New York State ! 2. Make it easy and accurate with automatic upload Utilities in New York should develop systems for automatic upload of aggregated whole-building data to Portfolio Manager • 24 of 29 utilities outside of NYS providing whole-building energy benchmarking data to customers have enabled automatic transfer to Portfolio Manager • New York City’s Department of Environmental Protection provides automatic upload of water data Image source: U.S. DOE, Better Buildings Energy Data Accelerator !
Advancing Benchmarking in New York State ! 3. Distinguish building owners from other users of customer energy data, and distinguish monthly data from interval data Regulatory approach should reflect that: Aggregation threshold = • Owners are distinct from third parties/ minimum # of meters for vendors – owners need whole-building access to whole-building data data to manage their buildings • A lower threshold promotes more complete • Aggregated whole-building monthly data benchmarking data and contains no individual customer easier access for owners information – privacy concerns can be addressed with reasonable terms & • Emerging national practice conditions (e.g. notices) of 2-5 meters • Benchmarking enables efficiency • Standard practice in New improvements, which serves REV’s York City for 5 years has policy objectives and the public good been 2 meters
