BOZEMAN – Workers used a crane Friday to hoist a new high-efficiency heat recovery ventilation unit to the top of 11-story North Hedges, one of the largest residence halls on the Montana State University campus, as part of an effort to make the building more energy efficient.
“This North Hedges project is a big success story for MSU regarding our ongoing efforts to increase energy efficiency across campus,” said Dan Stevenson, assistant director of MSU Facilities Services. “So far we’ve taken measures that have increased the building’s efficiency by 21 percent. Now, when this retrofitting project to the ventilation system is complete, we should see an increase in overall efficiency for this building of more than 60 percent since 2009.”
Built in 1967 and located in the residential complex just west of the campus core, North Hedges houses 668 students. The ventilation system being replaced is original and highly inefficient, Stevenson said.
The work should be completed by September. MSU has contracted with McKinstry Company for the project, with an expected cost of approximately $800,000. Stevenson said that investment should be recouped through energy cost and maintenance savings within 10 years.
This project is expected to reduce MSU’s greenhouse gas emissions by about 489 metric tons annually. MSU’s total emissions directly associated with campus operation are estimated at about 61,000 metric tons annually.
