Current Projects

Schwan Super Rink

CEE is working with the National Sports Center to provide recommissioning services for the Schwan Super Rink. As a state-owned facility and the world’s largest amateur sports complex, the NSC works hard to make the most of every operating dollar. They brought in CEE to identify low-cost savings opportunities to decrease their annual energy budget and improve overall operations of the ice rinks. Initial results identified over $96,000 in savings with a 2.7 year payback. These savings translate to just under 1,000,000 kWh, 80 kW, and 18,000 therms annually.

Braemar Ice Arena

CEE is working on this project with our long standing partner, the City of Edina. With aggressive goals to bring energy efficiency to every aspect of their operations, City officials contracted CEE engineers to recommission the Braemar Ice arena. Currently in its initial stages, the project will look at all energy-consuming equipment at three indoor rinks and one outdoor rink. In addition to the ice sheets, Braemar Ice Arena has a number of common meeting spaces with a retail shop and training center onsite. The goals of the project are to improve the energy efficiency of the entire arena, provide operations training for maintenance staff, and provide recommendations for the scheduled replacement of major equipment at the site. CEE will work with the City for the next year to complete the recommissioning and provide follow-up services to ensure recommendations are implemented and maintained to achieve the desired energy savings.

Courtyard Minneapolis Downtown – Marriott 

Heartland Realty Investors hired CEE to commission multiple rooftop units, a terminal unit, and controls system migration project to replace 30-year-old legacy equipment. The building is home to a hotel, restaurant, conference center, and ballroom. At the start of the project CEE performed a design review to help ensure the best equipment purchase choices. Project scope also includes construction and acceptance phases to make certain that improvements were implemented appropriately.

Contractors are now completing final balancing and controls work, so that engineers can perform final verification activities. CEE's continuous oversite of project contractors has ensured that the multiple rooftop units, terminal units, and new building control system are installed properly. Without proper installation, the units may have been left in an incomplete state, wasting energy and creating comfort issues for years to come. With CEE’s help, however, the building owner can see where work is still incomplete and keep contractors on track.

Historic Theatre Group

In partnership with NRG Energy Center Minneapolis, CEE was hired in 2013 to recommission building operating and maintenance systems in the Orpheum and Pantages theaters. Engineers found multiple opportunities for improvements such as excessive chilled water use, imbalances in the HVAC, and air flow, which impacted performances and events. Since the original recommissioning investigation, CEE continues to provide ongoing services to the Historic Theatre Group’s buildings, including the Orpheum, State, and Pantages theaters. Services include recommissioning implementation, targeted engineering analysis, and yearly Minneapolis Energy Ordinance assistance.

Maplewood Community Center & YMCA

The City of Maplewood retained CEE for a controls upgrade of their Community Center which also serves as the local YMCA. The previous outdated control system wasn't allowing for consistent control of the large and varying space conditions. The Community Center is home to a number of large meeting rooms, a theater for performing arts, a large gym, and an extensive indoor pool area with water features for families to enjoy. Engineers from CEE are completing the controls commissioning and test and balance verification work to ensure that the control and energy consumption of the HVAC systems are optimized to provide the best comfort possible for facility users.

Law Enforcement Center

CEE engineers are working with Washington County on a major controls upgrade for the Law Enforcement Center. Their outdated control system was causing energy waste and operational issues for County staff. The new controls upgrade will give them access to the latest control technology and provide them with reliable and efficient control of their HVAC system. This is extremely important for the center, since the facility is open 24-hours-a-day, year-round. CEE’s commissioning includes an initial design controls review, startup of all sensors and verification of control points, a functional performance test, and a system-wide test and balance validation. CEE and Washington County have a long standing partnership in achieving energy efficiency in all the County’s buildings.
