Trimming energy costs. A well-conceived conservation program can provide significant savings for hospitals

Healthcare facilities can realize significant savings on their energy costs if they adopt an effective energy management program. For hospitals beginning such a program, an energy audit is a good first step. Auditors observe and evaluate all energy-using systems and study factors that affect energy use. They then write a report containing on-site observations, an analysis of at least one year's energy bills, and recommendations for low-cost and no-cost energy-reducing measures and capital projects, including new installations and retrofits. Lighting is one area where costs can be cut significantly. During the past few years a revolution in lighting technology has provided many choices for new installation and retrofit. Many utility companies have established rebate programs for certain relamping projects. In addition, integrated heating, ventilating, and air-conditioning systems can present hospitals opportunities to improve patient comfort and energy efficiency. Maintaining and upgrading system boilers and chillers and installing equipment designed to adapt efficiently to changing seasonal needs can generate significant energy savings. Improved energy distribution and control systems should also be a part of a hospital's energy management program.
