International Square Lighting retrofit New VFD’s As a result of the reduced heat load, two 3,800 ton chillers were replaced with two 3,400 ton chillers Owned and Managed by Blackstone Cost Cost / sf Annual Savings Annual Savings / sf Payback ROI Asset Value Increase Annual Energy Savings $577,397 61¢ $241,500 26¢ 2.4 years 42% $3 mil 3 mil kWh 12 4 05/14/2012 HOW BAD (OR GOOD) ARE WE? BENCHMARKING WITH PORTFOLIO MANAGER WHAT IS BENCHMARKING? Benchmarking provides… • A method to compare the energy use of similar buildings over a given period of time. • The ability to conduct an “apple to apple” comparison using data to assess a building’s relative energy performance in comparison to the energy intensity of other known buildings. 14 EPA’S BENCHMARKING TOOL The US Environmental Protection Agency (EPA’s) ENERGY STAR® Portfolio Manager: • Is a free secure online energy management and tracking tool to help commercial buildings benchmark their energy usage • Allows tracking and assessment of energy and water consumption of a single building or across an entire portfolio of buildings • Can help a building owner or manager set investment priorities, identify under-performing buildings, verify efficiency improvements, and receive EPA recognition for superior energy performance 15 5 05/14/2012 USING PORTFOLIO MANAGER TO SET INVESTMENT PRIORITIES • Identify under-performing buildings to target for energy efficiency improvements first. • Establish a baseline to track progress over time Fire Stations - Energy Use Comparison 400 Energy Use Intensity kBtu/sq. ft 350 300 250 200 150 100 50 0 16 PORTFOLIO MANAGER PROVIDES: For All Commercial Buildings: • A weather normalized and non-weather normalized Energy Use Intensity (EUI) values (kbtu/square foot) and annual energy consumption (kbtu) • Direct, indirect and total greenhouse gas emissions • Ability to track financial performance information • Tools to set baselines & goals for % improvements over time • Reports and graphs to assess trends • Data for compliance and participation with a variety of emerging state, local, and federal regulations and voluntary programs For Eligible Buildings (As Defined By Portfolio Manager): • Eligible building types can also receive an ENERGY STAR energy performance rating of 1-100 17 ENERGY PERFORMANCE RATING WITH PORTFOLIO MANAGER Is 10 MPG high or low for an automobile? Fuel Efficiency MPG Is 90 kBtu/SF/YR high or low for an office building? Energy Efficiency Rating 1 - 100 18 6 05/14/2012 ELIGIBLE – RATABLE – SPACE TYPES Bank/Financial Institutions Courthouses Houses of Worship K-12 Schools Residence Hall/Dormitories Retail Stores Data Centers Medical Offices Senior Care Facilities Hospitals Hotels Office Buildings Municipal Wastewater Treatment Plants Supermarkets Warehouses 19 VALUABLE FOR ALL COMMERCIAL BUILDINGS • Track water use, energy intensity, and emissions • Compare to national average energy intensity for the building type such as: • Police Stations • Fire Stations • Libraries 20 OFFICIAL REPORT FROM PORTFOLIO MANAGER: STATEMENT OF ENERGY PERFORMANCE 21 7 05/14/2012 HOW DOES THE ENERGY PERFORMANCE SCALE WORK? Normalizes building variables affecting energy consumption… Building size Space type Weather Hours of operation Occupancy Plug load …and creates a whole building “mpg” rating www.energystar.gov/benchmark 22 ENERGY PERFORMANCE RATING IS A COMPARATIVE METRIC Best investment opportunities are in lower quartiles greatest potential for improvement Invest & Tune Invest 1 25 High scoring buildings provide lessons learned and label candidates RCx & O&M improvements yield savings and label candidates Reward & Learn Tune 50 100 75 Energy Performance Rating 23 “NEW” DOESN’T ALWAYS MEAN “EFFICIENT” Number of Buildings Based on a sample of 4,000 buildings nationwide. 39% of buildings with a rating of 75 or better are less than 25 years old 42% of buildings with a rating between 25 and 74 are less than 25 years old 35% of buildings with a rating between 0 and 24 are less than 25 years old 90 75 50 25 29.9 86.0 121.1 165.7 Best Performers Top performing buildings use 3 to 4 times less energy per ft2 than the worst performers. Newer buildings are equally represented across all quartiles. 10 1 339.4 EPA Performance Rating & Worst Performers Energy Intensity (kBtu/ft2-year) 24 8 05/14/2012 FOR TOP PERFORMERS: ENERGY STAR LABEL Energy Performance Score of 75 to 100 Obtain Verification from P.E. or Registered Architect Create and Submit Building Profile Submit SEP, Data Checklist & Application 25 ANOTHER REASON TO BENCHMARK!
