Retrofit of college building HVAC system reduces energy consumption and improves indoor air quality

Carleton University is a 52-year-old university located in Ottawa, the capital city of Canada. It has a 28-building campus with a student population of 22,000. The Loeb Building is the largest of the 28 buildings on campus and has a 238,000 ft{sup 2} (22,111 m{sup 2}) floor area consisting of four nine-story blocks. It was constructed in 1965 as a classroom/office building. Several years later, the fourth and fifth floors of Block A were converted to animal laboratories. Later, the animal laboratories were converted back to classrooms and offices. By 1991, as a result of occupancy changes and patchwork modifications, the building HVAC system was no longer functioning effectively. The most innovative aspect of the project described in this article was that a holistic approach was taken to the design where all of the design objectives were kept in mind. Substantial reduction in energy costs was achieved while improving the indoor air quality in all areas of the building and improving the operation and maintenance of the building. One design goal, such as indoor air quality, was not sacrificed to achieve another design goal such as energy savings. As a result, the Loeb Building has become a healthy, comfortable and energy efficient building on the Carleton University campus.
