The McGough Facility Management team continuously strives to improve Butler Square’s energy efficiency. Below are some examples of projects done in the past few years to reduce energy consumption in the building.
Since 2012 tenant spaces have been re-lamped installing lower wattage lamps/bulbs that last longer and use less electricity.
Antiquated time clocks were replaced by a “state of the art” Control 4 Lighting Control System. This system controls common area and outside lighting by a set schedule or light level sensors.
When building fan motors or speed drives fail, only up to date, high efficiency, and rebate qualified replacements are installed.
In the west building obsolete pneumatic air controls were replaced with up to date Energy Management controls. These air boxes control the heating and cooling of the building automatically, which results in less energy usage.
The emergency power system was upgraded to comply with the newest electrical and safety codes. This includes automatic switches for the elevators and emergency lighting.
A high efficiency boiler system was installed for the east building increasing nominal efficiency from 80% to 96% (when in the condensing mode); dramatically reducing the east building’s gas usage.
A 1980’s vintage roof supply fan was replaced with a high efficiency unit decreasing energy usage.
In 2016 the 1979 vintage cooling system in the west building was replaced with a new modular cooling system. Along with this all of the original pumps were replaced with more energy efficient ones adding variable speed ability to cut energy use. The new system uses a non CFC refrigerant which is environmentally friendly cutting CGS bearing refrigerants to near zero.
Janitorial Green Cleaning Practices/Purchasing-Green products are used wherever possible. Paper products are within Green compliant guidelines.
In 2015 Butler Square was awarded LEED SILVER designation.
In 2009 Butler Square was the first century-old, multi-tenant commercial building in the nation to receive LEED-EB-O&M certification (Existing Building Operations and Maintenance), the oldest building in Minnesota and Midwest to achieve LEED certification, and the first building in Minnesota to be certified under LEED-ED-O&M.
LEED is a benchmark for the design, construction and operation of high performance green buildings and certification is granted by the U.S. Green Building Council (USGBC). It is achieved by measuring the performance against a building rating system that encourages best-practice approach of developing, maintaining, and operating green buildings.
LEED buildings save money, resources, and have a positive impact on the health of occupants, while promoting renewable, clean energy.
Butler Square has received the prestigious ENERGY STAR designation for 2017 with a rating of 96% out of 100%, which means Butler Square is in the top 5% of similar buildings nationwide in energy efficiency.
The ENERGY STAR is the national symbol for energy efficiency in America. It is a symbol of an organization that is working to reduce global warming and its impacts.
Outstanding Energy Performance Award
On Nov. 2nd, 2017, the City of Minneapolis and building owners and management teams celebrated the second year of the Minneapolis Building Energy Challenge. Butler Square won the Outstanding Energy Performance Award. Butler Square’s energy use per square foot (50 kBtu/sqft), the lowest of any building in the Challenge, is outstanding on its own, and is even more impressive knowing the building is over 100 years old.

Butler Square wins Honorable Mention for Building Owner/Management Company Of The Year
The Commuter Choice Awards acknowledge programs and projects that improve commuter mobility in the Twin Cities. Butler Square was recognized for the promotion of sustainable behaviors and raising awareness and encouraging its tenants to use alternative transportation such as walking, biking, and using nearby public transportation instead of driving to work.
In 2016 Butler Square added a new safe, secure, indoor bike room for the tenants. There is enough space to park 70-75 bikes. The facility has such amenities as space efficient bike racks, a bike repair stand, and lockers.
Not only does biking to work have the potential to improve an individuals' health, wealth, and standard of living, but the combination of more cyclists and fewer cars on the road makes it a better place for all of us.
Butler Square is located within walking distance of the bus and light rail.
Each year Butler Square is involved with MOVE MINNEAPOLIS and sponsors a Commuter Transportation Fair for our tenants. The purpose is to promote making travel choices that offer a healthier person, environment and healthier finances. We challenge our tenants to replace drive alone trips with the bus, light rail, bicycle, carpool, or walking.
