The Cheeseheads… We’ve all seen them on TV. And if you live in the Green Bay area, odds are you’ve seen some in person during a Packers game at Lambeau Field. What you may not know is that one of Wisconsin’s largest mechanical contractors, Tweet/Garot Mechanical, teamed up with ENERVEX to complete a $146 million expansion of the field – which ended up on the cover of both PHC and Plumbing Engineering magazines for its success.

With the third-largest seating capacity in the NFL, Lambeau Field now seats 80,750 with a wall of fans reaching 30 stories, the highest point in the city! ENERVEX is proud to have our boiler draft control and combustion air systems as a part of the strategic playbook in this success!

Highlights of the Project

The Lambeau Field project led by Tweet/Garot focused on expanding the South End, as well as relocating the Packers’ Pro Shop, restaurant and team Hall of Fame within the stadium atrium. ENERVEX provided a boiler venting and inline variable speed exhaust system to help Lambeau Field’s design engineers maximize control over their energy consumption and costs.

The project entailed:

• Adding 7,000 seats to the outdoor section

• Mechanical draft upgrade to replace the boilers that kept the legendary “Frozen Tundra” warm & green throughout the season

• Systems radiantly heat the outdoor seating to melt snow as it falls on the upper deck

• 12 Fulton Vantage 4M BTU 95%

• Thermally efficient condensing gas-fired boilers with modulating draft control burners

• Boilers common vented through a manifold system of stainless steel pipe & ENERVEX inline variable speed exhaust system

Winning is About Taking Control

The ENERVEX system maintains a constant negative pressure in the stainless boiler flue pipe, exhausting flue products horizontally through a side wall near a rear loading dock. Combustion air is ducted from the outside to each burner, eliminating the need for combustion air louvers.

The crew now has unprecedented boiler draft control and efficiency because they can easily monitor the systems remotely, as well as control temperature and heat from below the soil. The systems allow them to adjust for conditions such as wind and shade that would otherwise be very difficult to control.
