In an energy audit for this 438,072 square foot hospital, four energy conservation measures were chosen. Included in the study were fluorescent lamp and ballast replacement, and variable speed chilled water pumping. Our calculations demonstrated a savings of $40,455 per year, or about a 16.9% ROI achieved in 5.9 years.
Resulting from our energy audit, Home Hospital chose DAE to upgrade their 1,000-ton chilled water system to a primary/secondary system incorporating 2 variable speed 125-hp secondary pumps.
