United Steelworkers Headquarters
Comprehensive Energy Efficiency
Completed in 1964 and originally named the IBM Building, the 172-foot tall United Steelworkers Building pioneered the use of both a load-bearing steel diagrid exoskeleton design and framed tube construction.
The building is supported by a steel exoskeleton resting on eight piers, two on each side of the building. Another intelligent part of the building’s structural engineering is the specification of different grades of steel depending on the strength requirements of each structural member.
The United Steelworkers (USW) turned to TEN to realize their energy efficiency goals for their headquarters building. Working with TEN, the USW achieved a 40% reduction in building energy and water consumption and earned LEED certification.
TEN’s project delivered:
- Comprehensive building energy/sustainability analysis
- Installed high-efficiency natural gas boilers
- Installed modernized elevators
- Upgraded new emergency generator
- Implemented extensive water efficiency equipment
- Modernized HVAC control systems and variable frequency mechanical systems
- Modernized building envelope energy efficiency features
- Installed renewable solar domestic water heater system
