T.J. Day Hall’s energy efficiency and environmental design has won it the Leadership Energy and Environmental Design Gold Certification.
The recently renovated T.J. Day Hall has earned Leadership in Energy and Environmental Design (LEED) Gold certification. LEED certification is awarded to buildings and institutions with sustainable building design, construction and operations.
President Hellie signed the American College and University Presidents’ Climate Commitment (APUPCC) in 2008 with the goal of eliminating greenhouse gases.
Linfield developed a policy that requires all new major construction projects to be built to LEED Silver standards. This includes all major remodels and new construction.
There is a formal application process and detailed verification that is required to obtain LEED certification. A rating system developed by the U.S. Green Building Council determines what level
of certification a building will receive.
“Obtaining LEED certification is a complex process where a third party evaluates 73 potential LEED credits within six categories,” said John Hall, director of capital planning and development, via email. “How many credits a building earns dictates what LEED certification will be awarded (Certified, Silver, Gold and Platinum). Categories include sustainable site, water efficiency, energy and atmosphere, materials and resources, environmental quality and innovation in design. T.J. Day earned credits in all six categories.”
Early in the design process, planners notified architects and engineers that it was necessary to design for a minimum of Silver LEED status, Hall said. They decided which credits to try to complete based on construction constraints and financial considerations.
Through the “Green Fee,” Linfield students funded
approximately $34,000 toward purchase and installation of the solar panel system on T.J. Day, providing 20 percent funding for the panels.
Hall said his favorite green feature in the renovated building is the radiant ceiling heating and cooling system.
“The T.J. Day facility is the third building in Oregon with this type of system,” Hall said. “It is very complex and efficient. At the south lower level entrance there is a description and an exposed panel showing how the system works. Due to low floor to ceiling heights, this was the most practical way to heat and cool most of the spaces within the building and is the most efficient.”
T.J. Day hall uses less
energy than a conventional building and conserves water. The toilets use dual flush systems, and the roof deflects heat to keep the building cool. A digital control system heats or cools the building based on class schedules and current temperatures of the rooms. Lights switch off when rooms are unoccupied, monitored by sensors.
“According to our engineers, the building operates about 30 percent more efficient than buildings constructed
with standard systems,” Hall said. “The building life is at least 75 years, so over the life of the building there will be significant savings to the college.”
Along with the remodeling of T.J. Day, the college
expanded science facilities, moved the business department from Taylor Hall to T.J. Day, moved the math department to Taylor Hall and remodeled Graf and Murdock Halls.
