THE CHALLENGE

Originally constructed in the 1960s, Manual High School’s HVAC system had not been upgraded since. In addition, the building did not have air conditioning. We were asked to provide a cost-efficient upgrade.

KED SOLUTION

We removed the antiquated boilers and replaced them with a more efficient hot water system. Use of a dual temperature system, which allowed us to run just one set of pipes for both systems, saved on piping costs. We added air conditioning through the installation of three 200-ton scroll chillers, quieter units that won’t disturb students’ learning. Finally, we engineered the building to operate on a zoned system, providing additional energy savings.
