Energy Benchmarking
• “Benchmarking is the practice of comparing the measuredperformance of a device, process, facility, or organization to itself, its peers, or established norms, with the goal of informing and motivating performance improvement.”
• “When applied to building energy use, benchmarking serves as a mechanism to measure energy performance of a single building over time, relative to other similar buildings, or to modeled simulations of a reference building built to a specific standard (such as an energy code).”

What is Energy Star Portfolio Manager®
• ENERGY STAR Portfolio Manager® is a free, online tool offered by the US Environmental
Protection Agency
• Used to measure and track energy and water consumption
• Benchmark the performance of one building or a whole portfolio of buildings
• Some building types eligible for an ENERGY STAR score and certification

CenterPoint’s MN Benchmarking Context
• 2012: Minneapolis benchmarking ordinance requires whole-building benchmarking for commercial
buildings
• February 15th, 2019: Minneapolis added Multifamily Buildings
• 2020: Edina and Saint Louis Park implemented new benchmarking ordinances
• Future: Other cities in CenterPoint’s service area are looking at benchmarking policies (e.g.,
participants in the Hennepin County Benchmarking Collaborative).
• Also, general increased interest in easy access to energy use data (especially aggregated
building-level data) e.g., green certifications

CITY OF MINNEAPOLIS
Energy Benchmarking Program
A Brief History
• Minneapolis Climate Action Plan• Adopted in 2013
• Updated GHG reduction goals, identified contributing sources, proposed reduction action steps
• Energy Pathways Study• Adopted in 2014
• Recommended a Clean Energy Partnership (CEP) between Minneapolis, CenterPoint Energy, and Xcel Energy
What is benchmarking?
Updated 03/2020 CEE.
• Benchmarking: is the ongoing review of building energy and water performance to ensure a building is using energy and water as anticipated—over time and relative to peers.
Benchmarking: How it Works

Who does the policy affect?
All commercial & multifamily buildings 50,000+ ft2 must annually benchmark their energy and water consumption and report this information to the City.
Historical Phase-in

Benchmarking Energy Evaluation Policy
• Benchmarking requires building managers to track and report energy and water performance annually
• Energy evaluation requires building managers to provide
proof of high performance or of an energy evaluation every five years
For commercial and multi-family buildings 50,000 sq.ft. and greater:
Example 50,000 ft2 building on Franklin Ave.
Energy Evaluation Policy Details
• Targets low-performing buildings by percentile.
• Buildings are reviewed by size group every 5 years.
• Evaluations are valid for 5 years.
• Only enforced IF there is an evaluation option
available at no cost to the owner
Energy Evaluation: Phase-in
Commercial and Multifamily 150,000+ sqft
Commercial and Multifamily 100,000 – 149,999 sqft
Commercial and Multifamily 75,000-99,999 sqft

Commercial and Multifamily 50,000 –74,999 sqft
Energy Evaluation Compliance
• 1. PERFORMANCE: Earn an ENERGY STAR score in the top 75% of scores within the city
• 2. CERTIFICATION: Achieve a qualifying green building certification within past 3 years. These include ENERGY STAR, LEED Gold or Platinum, Minnesota B3
• 3. PROGRESS: Achieve a 20% or greater reduction in weather-normalized energy use intensity over five (5) years
• 4. EVALUATION: Provide proof of an energy evaluation within the past five years.
Case Study: Becketwood Cooperative
• 210-unit, 55+ senior community
• Reduced energy use by 23%• Save $53,000/yr
• ENERGY STAR appliances
• LED conversion and roof insulation
• HVAC• ENERGY STAR chiller and energy recovery unit
“Emergencies cost far more than planned upgrades….with efficiency, success breeds success.”

Energy Data Portal Features
• Account holders can access
detailed account-level data for
their entire portfolio, and create
“meter groups” for
buildings/properties with
multiple meters
• Non-account holders/Third
Party Service Providers can
request permission from
building owner to access
building’s Energy Use Data
data
24
Proprietary and Confidential Information •
Energy Data Portal Features
• Buildings with tenants:
landlords can request
aggregated, whole-building
data by service address.
Energy Tracker then:
– Aggregates the data
– Evaluates whether data set meets
the privacy standards
– If tenant consent is required, data is
suppressed until consent is
received
25
Proprietary and Confidential Information •
Customer Energy Use Data Aggregation Policy
• Selected the 4/50 standard:
– Aggregated energy use data will only be released if the whole-building energy
use data contains at least 4 accounts and no single account’s usage
comprises more than 50% of the whole-building energy use.
• Applies to residential and commercial meters at a single service
address.
• Policy in effect with release of the Energy Data Portal

Energy Data Portal Features
• Building Owner Authorization and Tenant consent process is built into Energy
Data Portal and is fully electronic
