This summer, UNC’s Department of Housing and Residential Education renovated the central air conditioning systems in the two North Campus residence halls.
Students staying in the Olde Campus Upper Quad Community for summer school were moved to Kenan Community, said Steve Lofgren, assistant director of facilities for the housing department.
New windows were also installed in Mangum, Ruffin, Manly and Grimes residence halls, Lofgren said.
Lofgren said the construction cost about $3 million.
The housing department plans to spend an additional $2.3 million to upgrade the air conditioning in Manly and Grimes residence halls in summer 2015.
The systems were installed in 1989 and their age makes renovation necessary, he said.
UNC has a 10-year plan to renovate air conditioning units in certain residence halls.
"(The 10-year plan) covers North and mid-campus residence halls that have window air conditioners (Joyner and Teague, for example) as well as 25-or-more-year-old existing fan coils/central air conditioning (Lewis, for example),” he said in an email.
