According to the Environmental Protection Agency (EPA), healthcare organizations spend nearly $8.8 billion annually on energy to meet patient needs. In a typical hospital, the biggest consumer of electrical power is the HVAC system, accounting for as much as 42 percent of total usage. The HVAC system and chiller plant alone can push a hospital’s electric bills close to over a million dollars a year.
With the right peak performance strategy and technologies, it is possible to cut HVAC and central plant energy use by as much as 40 percent. As case in point, one of the USA largest public healthcare systems, Broward Health Medical Center (BHMC), registered savings of $311,000 in just one year, including more than $30,000 in a single month. This was possible after implementing Entic’s advanced analytics and optimization, providing visibility and transparency into the performance and service of its HVAC system and 6,000-ton chiller plant.
For a hospital, or any commercial building, the chiller plant is of critical importance. It is the circulatory system of the HVAC, responsible for the continuous flow of air. Yet the Department of Energy states that 95 percent of all chiller plants are inefficient. Does this mean that all of these plants are broken? No, however it does indicate that the plants at your facility are almost certain to be wasting energy and money, and you may not even know how much.
