Minneapolis, Minnesota

Project Highlights

Since February 2013, the City of Minneapolis has required all buildings 50,000 square feet and larger to report their annual energy and water benchmarking results through the Energy Star Portfolio Manager Program. This data is tracked and used by the city to understand how buildings are currently performing and to better understand a buildings progress year over year. Energy Star is a voluntary US Environmental Protection Agency program that allows buildings to assess how their properties are performing against other like buildings nationwide through a 1-100 scoring system.

33 South Sixth, also known as, City Center, is a 50 story 1.2 million square foot office building located in Minneapolis, Minnesota. Michaud Cooley Erickson (MCE) has been involved in the Energy Star tracking and certification for many years. MCE has also provided mechanical and electrical engineering services to maintain the sustainability requirements. MCE helped 33 South Sixth achieve LEED Gold certification by showcasing an automatic lighting control system, occupancy sensors in the emergency exit stairwell, VFDs to control all HVAC equipment and additional dampers on main air handlers to improve HVAC control and supply. The operations team also replaced two outdated chillers, two outdated cooling towers and inefficient light bulbs with LED lighting. Knowledgeable staff who prioritize sustainability have been critical in advancing these efforts. Additional improvements will occur as part of Shorenstein’s public commitment to reducing energy use 20% by 2020.

33 South Sixth Street earned an award for highest ENERGY STAR score in Minneapolis among commercial business buildings over 100,000 square feet, with a score of 98 out of 100 possible points. 33 South Sixth Street’s score of 98 indicates that the building performs better than 98% of all similar facilities nationwide!
