Benchmarking

What is ENERGY STAR® Portfolio Manager ®?

www.energystar.gov/benchmark

Assess energy, water and waste/materials consumption

1-100 ENERGY STAR score (available for many building types)

Track changes over time

Apply for ENERGY STAR certification

EPA’s 1 – 100 ENERGY STAR scores are based on market data

Nationally representative survey -CBECS gathers data on building characteristics and energy use from

thousands of buildings across the U.S.

EPA creates a statistical model that correlates the

energy data of the property use details to identify the key drivers of energy use,

accounting for weather variations

Compares the actual energy data for a

building to the modeled estimate to determine

where the building ranks relative to its peers on a

1-100 scale

EPA analyzes & filters the data - ensuring data robustness and quality

Value of benchmarking

Information Needed to benchmark

• Building type• Name, street address, ZIP/postal code

Property information

• Gross floor area• Use details (e.g., workers, operating

hours)

Property type data

• All purchased and on-site generated energy and water

Utility bills

Four Ways to Get Data in to Portfolio Manager

• Type in each number for each monthly entry

Manual Data Entry

• Use a spreadsheet to update one meter a time

Single Meter Spreadsheet

• Use a spreadsheet to update multiple meters from multiple properties

Multi-meter Spreadsheets

• Companies electronically enter utility data into Portfolio Manager through a process of data exchange called “web services”

How to submit your

benchmarking data to the city

DIY Quality Assurance

• Angry exclamation points

• Data Checker Tool

Top Benchmarking Errors

Wrong gross floor area

Wrong operating hours

Missing utility meters

Too many space types

Utility data entry errors

Energy Audits

Value of an Energy Audit

• Understand how energy is used in the building

• Identify opportunities for low cost / no cost and capital improvements

• Provide financial analysis of opportunities

What is an energy audit?

• Vendor proposal• Preventive maintenance / calibration• Cloud-based analytics tool• Only completed in order to meet the

city mandate

An energy audit is not…

• Objective study• Comprehensive – all energy sources

and uses• Feasible, concrete actions to save

energy• Financial analysis for strategic planning

An energy audit is…

ASHRAE Energy Audit

Levels

Level 2 Energy Audit Components• Building systems description• Utility analysis• Recommended measures

• Low-cost/no-cost• Capital projects

• Financial analysis• Energy and cost savings• Implementation cost• Simple payback/ROI

• Additional issues• IAQ• Maintenance considerations• Future measures

“Energy auditor” means

Bad audits

Missed opportunities

• Not feasible• Overstated savings• Understated costs

Wrong “opportunities”

Great audits!

Addendum: 2018 ENERGY STAR Changes

33

ENERGY STAR certification for existing buildings

• Recognition for superior energy performance – score of 75 or above, as calculated in Portfolio Manager and verified by a Professional Engineer or Registered Architect

• Based on a 12-month period of energy performance

• Buildings can re-apply for certification every 12 months

501 75

National Average

Superior Energy Performance!

1 to 100 ENERGY STAR scores

Eligible to earn the ENERGY STAR

Find certified buildings and plants: energystar.gov/buildinglist

Overall trend in U.S. building energy use (CBECS)

Because average energy and grid performance is improving, the ENERGY STAR scores and performance metrics of individual buildings will, on average, go down.

What does this mean for individual buildings?

Any other changes in August?

• New option: Estimated data center energy use ▪ Designed for smaller data centers, within another property type, and where it is not practical

to measure IT Energy▪ If IT energy is not metered, users will have the chance to apply estimates generated by

Portfolio Manager ▪ Estimate capped at 10% of the building area

Data center energy estimates

New use details in Portfolio Manager• Warehouse

▪ Percentage of gross floor area used for cold storage (New in August)▪ Percent that can be cooled and percent that can be heated (New in August for

refrigerated warehouses)• Worship Facilities

▪ Gross floor area used for food preparation (New in August)▪ Percent that can be cooled and percent that can be heated (New in August)

• K-12 Schools▪ Number of workers on main shift

o Exists now, but will be required in August • Supermarket

▪ Number of open or closed refrigeration/freezer unitso Exists now, but will be required in August

Preparing for the metric updates

• If needed, document pre-update metrics with Portfolio Manager reports

• “Performance Highlight” Report• Portfolio-level, multi-year

• Statement of Energy Performance

• Building-level, represents 12-month performance period

• Apply for ENERGY STAR certification (policy for 2018 only):

• If you earned 2017 ENERGY STAR certification for your building, you may apply for 2018 certification using a period ending date of April 30, 2018, or earlier. Applications submitted:

• Before July 26, 2018 and which require no significant follow-up or changes, will be guaranteed to be approved and awarded certification using the existing score models.

• July 26, 2018 – August 26, 2018 may be evaluated using the updated score models, especially if significant follow-up or changes to the application are required.

• After August 26, 2018 will be evaluated using the updated score models.
