This document discusses various ways that hospitals in India have optimized their central cooling infrastructure to reduce energy costs. Some key examples include: - KIMS-Hyderabad reduced cooling energy by 35% by consolidating their cooling load onto one chiller plant. - CARE Hospitals and others reduced costs by transitioning to more efficient water-cooled systems or heat pumps. - New variable frequency drive chillers and pumps at various hospitals are up to 70% more energy efficient than older models. - Other optimizations like eliminating unnecessary run hours, modulating set points, and implementing variable speed cooling tower fans have reduced energy use by up to 35% at different hospitals.
