GreenStep City Best Practices Buildings and Lighting

Efficient Existing Public Buildings
no. 1

Benchmark energy usage, identify savings opportunities in consultation with state programs, utilities and others to implement cost-effective energy and sustainability improvements.
  Best Practice Action 3      [ 1 2 3 4 5 6 7 ]       [all actions]

Invest in energy efficiency opportunities through larger financed projects or through smaller retro-commissioning/retrofit projects in city-owned/school buildings.

 
  • Before making changes to a building an energy audit is done at one or more (ASHRAE) levels, which range from easy/cheap to harder/costlier: Level 0 - Benchmarking (using historic energy data); Level 1 - Walk-through Audit; Level 2 - Detailed/General; Level 3 - Investment Grade.
  • Retrocommissioning corrects and enhances how building equipment and systems function together, resolving problems that occurred during design or construction or that have developed during the building's life. If the building went through the quality-assurance process called commissioning when initially designed and constructed, then a recheck is called recommissioning. Retrofitting improves building components, upgrades operating systems and equipment, and installs energy-efficient appliances.
  • The Guaranteed Energy Savings Program from the MN Dept. of Commerce - Division of Energy Resources is available for cities to lock in verifiable ongoing energy savings through vetted contractors and a master performance contract to achieve deeper retrofits without capital appropriations. GESP is most appropriate in general for situations including at least one of the following: city utility bills are at least $150,000/yr.; possible project cost is at least $350,000; city population is at least 10,000. The state's Division of Energy Resources operates this ongoing and other one-time financial programs.
  • DSIRE (Database of State Incentives for Renewables and Efficiency) is a one-stop source of information on the status of state programs and local utility programs, policies, and incentives.
  • Green Revolving Funds: An Introductory Guide to Implementation and Management (Sustainable Endowments Institute: 2013) explains and provides background on internal, self-managed revolving loan funds that finance energy efficiency improvements. The City of St. Paul, for example, has an Energy Conservation Investment Fund, a revolving loan account that supports energy-efficiency investments - retrofits of existing facilities - with a documented payback of less than 10 years for city-owned buildings.
  • See the ENERGY STAR Building Upgrade Manual, especially Chapters 5-10, and the Energy Analysis Tools from the National Institute of Building Sciences' Whole Building Design Guide.
  • Model procurement and contracting documents, and a website with model contracts and guidance documents for federal agencies > Energy Services Coalition and Federal Energy Management
  • Changing the Baseline Time Period: Click on the city building in the B3 Benchmarking left-hand menu bar, click on Baseline tab, find the Baseline Time Period, click on the twelve months (in orange type located to the left or below the colored gauges). Select the month-year that is 12 months prior to the start of implementing O&M changes in the building. (Status should be "Measured." If not, utility data still needs to be entered for this baseline period.) Posting a PDF Print Screen of the B3 Baseline tab for the building: Click on the city building in left-hand menu bar, click on Baseline tab, press Alt - Prt Sc keys on your keyboard, open a blank document and right-click Paste. Save As a PDF and post on GreenStep website.
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, GESP 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, 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.).

Burnsville

Date completed/entered:   05/02/2012

Implementation details:
Fire Station 1: All of the following changes were started in 2010 and completed by October of 2011. Some of the changes were the result of recommendations from an audit performed by Dakota Electric. Some changes, like the replaced furnace, were scheduled replacements. Most HVAC systems that will be replaced in Burnsville in the future will all be replaced with energy efficient models if funding allows. -Exhaust ventilation controls were installed -Programmable thermostats were installed -Outdoor ventilation controls were installed -All existing vents are now tied into the furnaces -The furnace was replaced with a high efficiency condensing furnace -Bay heaters were replaced with infrared heating -Outdoor lighting fixtures began converting to LED fixtures. Dakota Electric provided a $3,000 rebate for the air source heat pumps. CenterPoint Energy provided funding for the high efficiency furnaces. Burnsville City Hall: -In 2007 the chiller was replaced with a variable drive. -In 2010, a TPL Roof with R34 insulation was installed -Installed an Energy Management System -Converted all the pneumatic VAV boxes to electronic or digital control -Hot and cold water valves have been replaced with digital and electronic controls instead of air -A dozen outdoor fixturs have been replaced with LED lights. -In 2011, Maintenance Staff began converting interior lobby lights, property lights and several other areas to LED (26 LED fixtures in total). -In the process of signing a contract to install a high efficiency condensing boiler in the building. This will be completed in 2012. The following items will be completed in the next couple of years: -Circulating pumps will be replaced with variable frequency drives -Humidifiers will be replaced with more energy efficient models -All HVAC equipment will will be tied into the energy management system. In 2012, Burnsville created an Energy Efficiency Fund. The fund is overseen by Maintenance Supervisor Gary Novotny. This fund incentives purchasing energy efficient products by matching rebates and by selectively paying for energy efficient products that have longer paybacks, such as LED lighting. Currently the fund is being used to pay for outdoor LED lighting fixtures. The results of the program will be reported in Burnsville's Annual Report for it's Sustainability Plan. In addition, going forward, Gary Novotny and Sue Bast will report progress on the GreenStep Cities Site.

Outcome measures/metrics:
Fire Station 1 energy consumption reduced 13.76% post retrofitting. City Hall energy consumption reduced 15.65% post retrofitting. Burnsville created its Energy Efficiency Fund in 2012. The results of the program will be reported in Burnsville's Annual Report for it's Sustainability Plan. In addition, going forward, Gary Novotny and Sue Bast will report progress on the GreenStep Cities Site.

Eden Prairie

Date completed/entered:   03/13/2012

Date updated:   07/15/2014

Implementation details:
The 20-40-15 initiative, first rolled out by the City of Eden Prairie in December 2006, calls for the City to improve energy efficiency in all of its facilities by 20 percent, increase the fuel efficiency of its vehicle fleet by 40 percent, and accomplish these goals by the year 2015. The City is working closely with McKinstry Company, a firm touted by President Barack Obama as a “model for the nation” for its work in retrofitting schools and office buildings throughout the country to make them more energy efficient. The City’s partnership with McKinstry Company guarantees the estimated savings from the projects it recommends will pay for the cost of implementing those projects as well as the firm’s consulting fees. If the savings fall short of the costs the City incurs, McKinstry Company will make up the difference. The City encourages Eden Prairie residents and business owners to become more energy efficient and embrace environmental stewardship. The January 2009 issue of Life in the Prairie includes some great tips to get started, as well as other resources to help in this effort.

Outcome measures/metrics:
The City is implementing the projects in phases. Some of the actions the City has taken include replacing standard stop lights with light-emitting diode (LED) lights that use 90-percent less energy. The City has also added motion sensors to control lighting in meeting rooms, adjusted the timers which control lighting and HVAC after hours, and re-lamped several light fixtures and signs to utilize energy-efficient LED bulbs. Repairs to City buildings have helped reduce the amount of heated and cooled air that escapes to the outside. The City encourages Eden Prairie residents and business owners to become more energy efficient and embrace environmental stewardship. The January 2009 issue of Life in the Prairie includes some great tips to get started, as well as other resources to help in this effort.

Eagan

Date completed/entered:   04/25/2012

Date updated:   05/07/2014

Implementation details:
The city received a $657,000 Federal Energy Efficiency and Conservations Block Grant to upgrade city owned buildings to make them more energy efficient. The consulting firm of McKinstry oversaw the project and leveraged the grant dollars with utility rebates that resulted in $1.2 million in improvements. The City receives rebates from Dakota Electric and other utilities as a result of the projects funded through the Energy Efficiency and Conservation Block Grant. Examples where rebates were received include building recommissioning work and interior lighting upgrades. The City also participates in Dakota Electric's load shedding program to reduce peak demand electricity needs, which results in a rebate to the City.

Outcome measures/metrics:
The city received a $657,000 Federal Energy Efficiency and Conservations Block Grant. The direct impact of the retrofits resulted in significant energy, dollar and CO2 savings for the buildings receiving the retrofits; in particular the Municipal Building, Police Building and Maintenance Facility. Underperforming buildings will have a targeted plan to make modifications to meet defined goals. In particular, each building that is currently underperforming after the initial retrofits will have a 3-5 year plan wherein energy enhancements that were not included as part of the initial energy audit will be planned and budgeted for. The continual tracking of energy use and costs through B3 will provide the tangible data to prioritize which buildings need the most attention to meet the energy saving goals.

Hopkins

Date completed/entered:   09/27/2012

Implementation details:
Hopkins had two buildings fall into the bottom third of the B3 energy performance ranking: City Hall and the parking ramp. In November '10 City Hall received new boilers and the parking ramp is scheduled for new lighting by Spring '11. Both projects are eligible for rebates; the boiler room has been submitted for 3892.00. The reduced use of natural gas in 2009 was due to the decision to take the boilers off line during the summer months instead of running them year round. The fuel usage so far this year for the new boilers is running about 30-40% below last year's usage. The boiler savings are starting to show up only 3 months after replacing the old boiler. The City's estimated savings is around $8,000.

Outcome measures/metrics:
City of Hopkins fuel costs before and after boiler upgrade (2009 cost/2010 cost) Sept-Oct: $937/$96. Oct-Nov: $1165/$759. Nov-Dec: $2667/$1786.

Woodbury

Date completed/entered:   04/26/2013

Implementation details:
All city buildings have had recommissioning studies completed, as well as lighting retrofits. In 2007, Woodbury City Hall was remodeled, including a 13,841 sq. ft. addition to the building. Energy improvements included a geothermal system, a south facing glass facade to maximize daylight, energy efficient mechanical and electrical systems, energy efficient lighting, and occupancy sensors. An energy management system allows the city to control the energy use based on occupancy. The project also featured installation of a green roof, porous paver parking stalls, low-flow water fixtures, a rain garden, and the installation of "Grasspave" and "Advanced Turf" along walking paths to handle truck loads without adding impervious surface. In 2009, Woodbury replaced the existing ice arena refrigeration system at Bielenberg Sports Center with an energy-efficient geoexchange (or ground source heat) system. The new system is estimated to prevent 1,024 metric tons of CO2 emissions and result in $100,000 in utility cost savings. The project also included installation of low emissivity ceilings, a new energy management system, and fixture retrofits for water conservation. During the Summer of 2011, the city remodeled and expanded the public safety building to include a geothermal system for heating and cooling. In October 2012, a 40kW solar PV array was installed on the building. The project also included the addition of a parking garage for public safety vehicles. Since the vehicles previously idled for long periods to keep computer and medical equipment from freezing, the garage eliminated the need for continuous idling. Fuel savings averaged througout the year equals 1,100 gallons of fuel each month.

New Brighton

Date completed/entered:   05/03/2016

Date updated:   05/03/2016

Implementation details:
The City Initiated Roof Top Unit (RTU) replacement project at the New Brighton Community Center (NBCC) using Trane as a vendor through the US Communities Government Purchasing Alliance. This project is scheduled for completion in September of 2016. The efficiencies that can be gained by following the Trane recommendations will allow the City to maximize the comfort of the environment for the building’s users while reducing payback time and maximizing control of the building. Trane completed a study on the performance of the current HVAC system at NBCC by utilizing data logging devices that were installed at various locations inside the building. The data found shows the current RTU’s are not working at optimal levels. This impacts the comfort level of NBCC visitors and doesn’t allow the NBCC to operate at peak efficiency. It is also demanding on the RTU’s as they are forced to work harder to overcompensate for the various swings in temperatures. This results in higher energy bills and potential repair costs. The RTU’s are also not working at optimal levels due to the units being near the end of their useful life. An absolute necessity to utilizing any new HVAC system to the fullest extent possible is to replace the current pneumatic controls as part of this project. The NBCC’s current outdated pneumatic controls will be replaced with Direct Digital Controls (DDC). DDC will allow greater control in various areas of NBCC. The City will seal leaks that have been identified in the exterior wall and roof deck connections as well as window and door frame leaks during the NBCC project to resist infiltration of air, water, heat, light, and noise transfer from exterior to interior, or from interior to exterior LEDs will replace the current fluorescent and Compact Fluorescent Lamps (CFL) used at NBCC. This will reduce the amount of energy necessary to operate NBCC and provide high quality lighting. Based on the longevity of LED bulbs will require less staff time to replace when they have burned out. Another maintenance issue that will be resolved is it will no longer be necessary to replace the ballasts to light fixtures, reducing both the equipment cost and again staff time to perform this task. Currently there are different types of lighting fixture types used at NBCC. This includes LED fixtures that were installed as part of the locker room/restroom renovation project, fluorescent tubes and CFL’s as well as metal halide fixtures that provide exterior lighting at NBCC. There are approximately 2,000 fixtures and lamps that would be retrofitted to LED. New LED's are planned for installation in August-September.

Outcome measures/metrics:
The new RTU's will provide 15-20 years of energy savings. Energy use data following the project completion dates will be used to compare to existing B3 database records.
