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

• What gets measured gets improved

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

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 Efficiency Resources

• http://www2.minneapolismn.gov/environment/energybenchmarking

• Minneapolis Green Cost Share Program -• Commercial buildings and multifamily (four+ units) for energy efficiency

• Priority given to buildings participating in the Minneapolis Energy Benchmarking program.

• Application deadlines: December 1, February 1, April 1, June 1 of each year.

• Funds are limited

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

26

Proprietary and Confidential Information •

Energy Data Portal Features

• Building Owner Authorization and Tenant consent process is built into Energy

Data Portal and is fully electronic
