City Assessment Files and City Performance Metrics

City councils pass a resolution to join the GreenStep program and are recognized at Step 1. Step 2 and Step 3 recognition levels reflect completed city actions, reported and rated below with stars (1 star = good, 2 stars = better, 3 stars = best). The Assessment Files below summarize completed city actions in a short Word file. Step 4 recognition is awarded each June to cities who report a minimum number of optional (and a few high-priority/core) metrics for the previous calendar year. These metrics - see guidance documents for them at http://www.betterenergy.org/step4 - aim to show the aggregate, quantitative results of taking multiple GreenStep actions. Step 5 cities show improvement beyond minimum thresholds in the Step 4 metrics. See yearly data in the Metrics Files below.

Total completed actions: 8     1-star actions: 3     3-star actions: 5    







Buildings and Lighting   Buildings and Lighting

Efficient Existing Public Buildings
{ BP no. 1 }

Complete the Building Editor for each city-owned building; identify the person responsible for routinely entering data; enter current (at least once/90 days), consecutive monthly energy use data ongoing; also best to enter 12 consecutive months of historical energy use data.
Complete 1 Star criterion and enter 24 consecutive months of historical data; routinely validate newly entered data by looking at patterns/trends and inconsistencies; correct inaccurate entries and identify potential opportunities for energy savings; showcase your B3 public page/results on your city web site.
Complete 1 and 2 Star criteria, routinely ID energy-related operations and maintenance issues and poorer performing buildings for follow-up action; routinely enter current and consecutive (monthly or quarterly as available) water use data ongoing.
Action 1: Enter building information into the Minnesota B3 Benchmarking database and routinely enter monthly energy, water use data for all city-owned buildings.     [Click here for self-reported city details ]  


Implement changes in one poorer-performing building and summarize the actions taken: switch to LED lights; updating temperature, ventilation and lighting schedules and setbacks; occupancy sensors on lights/automated light dimmers; installing building-wide computer and office equipment power management software; assigning responsibility for turning off manual lights and other shared equipment; assuring that routine HVAC maintenance schedules are thorough and implemented at appropriate intervals; revising janitorial schedules to day-time hours; adjusting janitorial responsibilities to include regular cleaning of sensors, lamps and HVAC vents; installing lower-flow faucet aerators, dish sprayers, and showerheads to reduce hot water use.
Complete 1 Star criterion for two buildings. Post the Print Screen of the Baseline tab for one of the buildings with the Energy gauge showing at least a 5% decrease in energy use compared to the baseline period [12 months immediately prior to implementing changes]. Continue fine-tuning operations and maintenance procedures and monitoring energy usage to identify opportunities for additional savings.
Complete 1 and 2 Star criteria for two buildings. Use B3 to report at least a 10% decrease in energy use compared to the baseline period.
Action 2: Make no/low cost indoor lighting and operational changes in city-owned/school buildings to reduce energy costs.     [Click here for self-reported city details ]  


Complete retrocommissioning and/or retrofitting work on one building. Summarize the actions taken. Update the B3 Building Editor as needed and change the Baseline Time Period to report energy/cost savings.
Complete retrocommissioning and/or retrofitting work financed by an energy performance contract, utility rebate or other means on two or more buildings. Post a print screen of B3 data to report energy/cost reductions.
Complete 1 and 2 Star criteria. In addition, use GESP or implement an internal program or use an external program/vendor that institutionalizes, and provides funding / incentives for, ongoing reductions in energy use by city-owned buildings (e.g. internal loan fund, shared savings with employees, capital budgeting based on energy savings, performance incentives and accountability, etc.).
Action 3: Invest in larger energy efficiency projects through performance contracting or other funding or through smaller retro-commissioning/retrofit projects in city-owned/school buildings.     [Click here for self-reported city details ]  


Efficient Existing Private Buildings
{ BP no. 2 }

Program activities include but are not limited to: information/education efforts via newsletters and the like; work with the local utility, local Community Action Program, local bank, or others; promote utility load management programs (fuel-switching, AC/water heater cycling); program participation reports. Report a rebate program to promote purchases of WaterSense-rated appliances under action 2.5; report work with businesses under action 25.2; report broad sustainability campaigns that go beyond energy efficiency under action 24.4
One or more of: provide more in-depth energy use reports; explicitly focus on improved indoor air quality; partner with others on low-interest loans, assistance to homeowners on weatherization, efficiency improvements; incentivize Home Energy Squad or other home energy audit program visits and residential efficiency improvements; resident participation in the National Mayor's Challenge for Water Conservation.
Participate in Xcel's Partners in Energy program; create a city program and report on number of households participating (e.g. took advantage of rebates, loans, grants, attended workshops, received home energy audit) and dollars or BTUs or therms saved.
Action 1: Create or participate in a marketing/outreach/incentive program to promote/achieve residential energy/water use reduction and energy efficiency.     [Click here for self-reported city details ]  


Provide education/information around lawn watering and home water conservation and rain barrels; summarize watering ordinance but report conservation rate structures and dynamic user feedback under action 20.7, rain gutter disconnects from sewers under action 20.3; education about home water softeners under 20.4
Report residential water use under 75 gal/capita/day; modify and adopt a model landscaping ordinance that encourages low water-use landscaping; assist owners of automatic or underground irrigation systems to install the state-required rain/moisture sensors; report water use reductions; become a WaterSense Partner.
Create and report on a rebate or feebate program to promote purchases of WaterSense- and/or Energy Star-rated appliances; review building water conservation strategies during development reviews; as code allows facilitate household/building site rainwater harvesting/reuse; prohibit city water from supplying lawn irrigation systems.
Action 5: Conserve/protect drinking/groundwater resources by creating a water-wise landscaping ordinance/guidance, WaterSense purchasing program, or guidance on rainwater harvesting and home water softener use.     [Click here for self-reported city details ]  


Environmental Management   Environmental Management

Urban Forests and Soils
