Most retrofits are challenged by the difficulty of replacing old, cumbersome ductwork, but imagine retrofitting a building designed before air conditioning! That was the challenge in Grand Coteau, Louisiana, where Reverend James P. Bradley, S.J., wanted to update the HVAC system at the Jesuit Spirituality Center at Saint Charles College. The solution to that challenge: our VRF technology.
The century-old building houses a novitiate (Jesuit training center), a spirituality center for retreats and a 22-bed assisted living facility. For such a large, diverse project, Larry Blanchette, the project’s engineer, elected to use our VRF technology for a number of reasons:
- Cost Efficiency – Compared to the chilled water and hot water system that Blanchette initially planned to incorporate, VRF simply priced out better.
- Spacing – In a building that covers the equivalent of a city block, there were a number of large beams hidden in the structure. The building’s size and layout presented a challenge that VRF’s compact design was able to help navigate.
- Mold – With high humidity and 22 elderly residents, mold was a constant threat. VRF offered personalized comfort and better indoor air quality. “A couple men had asthma and allergy problems, but they’ve gone away,” said Bradley.
Above all, a central controls system has made managing the facility not only convenient, but has also kept the project under the expected cost.
