2 Data Comparisons Actual gallons per occupant/day To same city over time To other cities 132 U.S. averages 150 To the world 5 To projections 122 2

3 Participating Cities Falcon Heights, MN St. Louis Park, MN Edina, MN [new] 3

4 MN GreenStep Cities Best Practices 4

5 Study scale City wide versus organization data 5

6 Scope of Work Establish the feasibility of this approach. Collect the last two years of data for benchmarking. Establish a process for collecting data for the next two years. Evaluate the specific best management practices (BMP) selected by each city and correlate them to the outcomes being measured. Produce a final report that measures each metric individually (i.e. kbtus, gallons, vehicle miles traveled, etc.) as well as in total dollars and tons of carbon. The report will include data on a per capita basis as well. 6

7 Units & Normalization BTUs Gallons VMT Pounds Energy Water Vehicle Miles Traveled Waste All can be converted to $ and CO 2 All can be normalized to population and/or jobs 7

8 2009 Data Falcon Heights, MN Energy Residential 88 kbtu/person/day Water Residential 39 gallons/person/day Energy Commercial / Industrial 164 kbtu/job/day Water Commercial / Industrial 123 gallons/job/day VMT 16 miles/person/day Waste 6.9 pounds/person/day 8

9 ARCH 2030 GOAL DESIGN MODEL ACTUAL BUILDING FAST FACTS ACTUAL ENERGY USE IS CALCULATED FROM METERED UTILITY DATA THE ARCHITECTURE 2030 GOAL CALCULATED AS A PERCENTAGE OF CODE BASE THE DESIGN MODEL AND ACTUAL ENERGY USE OF THE PROJECT kbtu / sq. ft. / year ENERGY USE INTENSITY (EUI) IS A MEASURMENT COMPARABLE TO MILES PER GALLON WITH AN AUTOMOBILE. DESIGN MODEL ENERGY USE RESULTED FROM THE ENERGY DESIGN ASSISTANCE PROGRAM WITH THE WEIDT GROUP AND XCEL ENERGY. ARCHITECTURE 2030 GOAL IS CALCULATED AS 50% OF THE DESIGN MODEL CODE BASE ENERGY OF THE PROJECT ENERGY

19 Conclusions/Next Steps We can measure community wide data We can normalize by job and population There is correlation to the GreenStep BMP s Energy is the largest part of the pie Commercial/Industrial consumption is greater We can establish targets for each unit Our Comp plans should include these targets Every city in the Regional Council of Mayors should collect this data 19
