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 File below summarizes completed city actions in a short Word file. Step 4 recognition is awarded to cities who report a minimum number of core metrics for the previous calendar year. These metrics aim to show the aggregate, quantitative results of taking multiple GreenStep actions. Step 5 cities show improvement in the Step 4 metrics. See yearly data for Steps 4&5. Additional city data can be found by reviewing information on B3 Benchmarking and Regional Indicators Initiative.

Buildings and Lighting Buildings and Lighting

Efficient Existing Public Buildings {BP no.1}

3 star - Action 1:

Enter building information into the Minnesota B3 Benchmarking database and routinely enter monthly energy, water use data for all city-owned buildings.

Date action report first entered:
Date of last report update:
Implementation details:
Lakeville has been entering data into the Minnesota B3 Benchmarking website monthly since 2010 with historical data going back to 2007. Trends for each building are reviewed periodically to gauge energy performance and look for ways to improve efficiency.

3 star - Action 2:

Make no/low cost indoor lighting and operational changes in city-owned/school buildings to reduce energy costs.

Date action report first entered:
Date of last report update:
Implementation details:
The City completed updates to its building automation software in 2018 and centrally controls the HVAC temperature, setbacks, and mechanical settings in 12 buildings. Janitorial staff was changed to daytime hours in 2016. Filter changes on air handling units are performed four times per year by both City and contractor staff to improve performance. A high-efficiency condensing boiler was installed in 2017. LED lighting retrofits are completed annually within City facilities as fluorescent tubes and fixtures need replacement. Occupancy sensors for high bay fluorescent light were installed in the Central Maintenance Facility truck garage in 2005 with the construction of the building and are monitored and adjusted as needed to maintain efficiency.

Invest in larger energy efficiency projects through performance contracting or other funding or through smaller retro-commissioning/retrofit projects in city-owned/school buildings.

Date action report first entered:
Date of last report update:
Implementation details:
The City has completed a study with Apex Efficiency Solutions that reviewed each of the City's facilities for energy savings, operations and maintenance savings, and potential incentives available from the utilities. With lighting upgrades, HVAC improvements, and building envelope improvements, potential savings total over $161,000.

Efficient Existing Private Buildings {BP no.2}

3 star - Action 1:

Create or participate in a marketing/outreach/incentive program to promote/achieve residential energy/water use reduction and energy efficiency.

Date action report first entered:
Date of last report update:
Implementation details:
In 2018, the City began an initiative to reduce urban water usage by optimizing private irrigation system efficiency. Irrigation audits were conducted at two homeowners associations to review system components (controllers, sprinkler heads, rain sensing technology), scheduling practices, and uniformity of water application. The audits provided the HOAs with a list of items that could be implemented to keep more water within local groundwater aquifers, reduce the potential for pollutants to enter local creeks and lakes, and save on annual irrigation costs.

1 star - 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.

Date action report first entered:
Date of last report update:
Implementation details:
In 2007, the City adopted a water use ordinance specifically to address residential lawn watering and irrigation practices. Impacts to the City's water system were felt particularly during hot summers water levels in the aquifer drew down and it was harder to pump water to replenish storage tanks. The ordinance specifically restricted customers to odd or even day watering and prohibited watering between 11:00 a.m. and 5:00 p.m. daily. Exceptions were allowed to hand watering of gardens and the establishment of new sod.
