Study outlines strategies hospitals can implement to reduce energy use by 62%, save money

I found this study yesterday that identifies a process for newly constructed hospitals to integrate architectural, mechanical and central plant systems to reduce energy consumption by an average of 62%.

Courtesy: Cannon DesignI found this study yesterday published by the University of Washington, titled Targeting 100! that identifies a process for newly constructed hospitals to integrate architectural, mechanical and central plant systems to reduce energy consumption by an average of 62%.

The biggest breakthrough identified by the study comes from addressing the reheating of centrally-cooled air, which is the largest contributor to wasted energy in a hospital, representing more than 40% of annual heating energy use. The study also identifies strategies including sun and daylight shading controls, vacant room sensors, outdoor air supply with heat recovery systems, modified air delivery systems, thermal energy storage and improved air-tightness and high insulation values in windows and walls that can help hospitals save between $500,000 and $800,000 a year in energy costs.

I read stories and studies like Targeting 100! and it makes me wonder why any hospital accepts less than these standards. Working with firms like Cannon Design, hospitals can begin implementing these measures to save money, energy and create stronger healthcare environments. Kudos to the University of Washington for pushing this study—it will help drive progress in our healthcare environments.
