The most recent data published by the Department of Energy says new commercial buildings add only about 1% to the total U.S. building stock each year. This means new sustainable buildings alone are not enough to make an impact on our carbon footprints. Retrofitting existing building stock to be more energy-efficient and sustainable needs to be at the forefront of green construction. Warren Hall achieved LEED Platinum Certification, a first for a building renovation on campus. Rich in economic and social science history, the Warren Hall renovation reinvigorated and modernized a 100 year old structure delivering a modern building with a zero increase in the energy use.

How is "Green” measured?

Under the LEED Green Building Design and Construction standard, a credit system with a maximum of 110 points is used to measure environmental performance.

The USGBC (U.S. Green Building Council) awards points in 5 main categories:

  • Sustainable Sites
  • Water Efficiency
  • Energy/Atmosphere
  • Materials / Resources
  • Indoor Environmental Quality (IEQ)

What are the Possible Ratings?

A project can earn additional points for innovative approaches and by having a LEED accredited professional part of the project Team.

Project Highlights

  • Much of the character and soul of Warren Hall can be derived from the historic quality finishes that existed in the building before the renovation. Architects strove to restore and enhance the building functionality while respecting the existing building character. One opportunity seized on included the restoration of 1,600 square feet of salvaged stone flooring.
  • The building uses extensive daylight penetration to lower energy costs used to light the space and to create a connection between occupants and the outdoors. In addition to lowering lighting and cooling costs, increasing daylight to occupant workspaces has been shown to have health benefits for occupants and increase productivity.
  • Instead of simply installing new forced air ventilation systems that would require energy to operate, the building designers included operable windows and trickle vents in the office spaces to allow occupants to control their own ventilation preferences, access fresh air, and save energy.
  • Many historic features such as windows and fireplaces were protected and maintained to preserve the character of the building, while others were recreated such as the ceiling coffering and woodwork inlay patterns. Material selections were carefully made to enhance the environmentally friendly attributes such as recycled content or regional manufacture.
