The Solutions
CMTA was able to bring several value strategies to the table for Baptist Health during this project, including First 30 and Design Innovation. We met with Baptist at the very beginning of the project and analyzed the capacity and the energy usage of the existing central plant. Studying their energy bills provided great opportunity for significant energy reduction.
Because we were marrying a renovation project to new construction, we had to utilize multiple energy-saving strategies to achieve maximum efficacy. A 1,000 ton heat recovery chiller was added to the central plant to utilize waste heat off of the compressor to heat the entire new building, portions of the old building, and all of the domestic water heating on the campus. The existing chiller plant operated with a traditional primary-secondary pumping arrangement. We switched this to a variable flow primary system to increase plant efficiency. This was designed and coordinated to prevent any downtime to the hospital to maintain patient comfort and safety. Additionally, all of the condensation from the air handling units in the new patient tower will be collected and pumped back to the cooling towers for makeup water.
Our overall schedule was impacted by budget constraints, as the client chose to pay for the energy improvements as they went. This led to a multi-phase schedule, as well as multiple bid packages, which we helped the client manage.
