ENERGY BENCHMARKING Unlocking Efficiencies in New Yorks Buildings - - PowerPoint PPT Presentation

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%! 60%! 75%!

• f national CO2 emissions!
• f New York State CO2 emissions!
• f New York City CO2 emissions!

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!

What Is Benchmarking?!

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!

Benchmarking for state buildings >20,000 square feet (Gov. Cuomo’s Executive Order 88)

• 2,261 buildings
• 212 million square feet
• 90% of state-building floor area,

energy use and energy cost !

Current Benchmarking Policy in New York!

A national leader – Now in its fifth year of benchmarking for all buildings >50,000 square feet

• ~15,000 properties and ~25,000

buildings

• More than 2.3 billion square feet
• ~50% of NYC floor area

New York State New York City

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 Aligns with REV!

Benchmarking Benefits Multiple Stakeholders!

For:! Benchmarking:! Provides additional information about buildings and their systems, which can be the basis of future customer engagement Increases demand for energy efficiency programs, helps prioritize efficiency incentives and enables pay-for-performance programs Utilities! Owners & Managers Enables informed building efficiency investments Makes building performance visible and valuable in the marketplace Tenants, Buyers & Investors Policymakers! Provides novel insights to shape effective energy and carbon policies

BENCHMARKING IMPACT

Allows Owners to Track & Compare Energy Use!

Identifies Most Impactful Efficiency Targets!

Multifamily buildings dominate the number, floor area, energy use and GHG emissions in New York City

PlaNYC New York City Local Law 84 Benchmarking Report, 2012 !

Illuminates Potential Policy Impacts! 18-31% energy savings and 20-33% lower GHG emissions by bringing all

buildings to the median or 75th percentile in NYC

Benchmarking Drives Efficiency!

Portfolio Manager (35,000 buildings) 2008 to 2011 Average energy savings:

7% ! 9% ! 7.9% ! 5.7% !

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 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, 1 meter! 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

* 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

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:

• Owners are distinct from third parties/

vendors – owners need whole-building data to manage their buildings

• Aggregated whole-building monthly data

contains no individual customer information – privacy concerns can be addressed with reasonable terms & conditions (e.g. notices)

• Benchmarking enables efficiency

improvements, which serves REV’s policy objectives and the public good Aggregation threshold = minimum # of meters for access to whole-building data

• A lower threshold

promotes more complete benchmarking data and easier access for owners

• Emerging national practice
• f 2-5 meters
• Standard practice in New

York City for 5 years has been 2 meters
