building

Memorial Hospital of Carbondale is a 365,519-square-foot (and growing) facility that has more than doubled in size over the past 30 years. In addition to acute care space, the hospital provides various outpatient services and has an adjoining professional office building.

Beginning with an energy audit in 1980, the hospital's team of facilities and engineering staff incrementally incorporated energy saving features into new construction, renovation, and replacement and upgrade projects. These efforts went a long way toward making this hospital one of the first three hospitals in the country to earn the ENERGY STAR for superior energy performance in 2001.

The hospital's energy management team is continuously expanding the building automation control system and has taken the following steps to improve energy efficiency over the last 30 years:

-- Lighting: The team uses fluorescent lighting whenever possible and upgrades old fixtures during renovation with electronic ballasts and efficient lamps. They also replaced fluorescent exit signs with LED exit signs.

-- Fan Systems: Most of the hospital's fan systems are variable air volume (VAV) systems with variable frequency drives (VFDs) that control the fan speed and air volumes. The team also uses low pressure drop filters to reduce fan horsepower.

-- Pumping Systems: The primary heating and cooling water systems are operated with variable speed pumps to provide the proper flow for the current conditions.

-- HVAC: The team replaced many of the pneumatic systems with digital direct control (DDC) systems over time. The hospital's HVAC system upgrades often result in improved comfort for building occupants.

-- Central Chilled Water System: One of the first long-range energy conservation projects was to eliminate standalone direct expansion air conditioning systems by developing a central chilled water plant to provide cooling for the facility. Cooling is provided by multiple centrifugal and screw water-cooled chillers that provide the needed capacity and system redundancy. The chillers vary in size and the automation system selects the appropriate chiller(s) to match the building load.

-- Water-to-Water Heat Pump System: The team's research showed that during much of the year, very low heating water temperatures suffice for the hospital. By using lower temperature heating water, they are able to use a water-to-water heat pump system to capture heat from the building's chilled water system and transfer it through heat exchangers to heat the building heating water. Even in the winter, the heat generated from inside the hospital is used in this way.

-- Training Commitment: The facilities engineering staff receive ongoing training to achieve peak performance in the operation of systems and equipment. Training is provided by the design engineers, and several staff members have achieved Building Operator Certification from the Midwest Energy Efficiency Alliance. The team is also active in the Association of Professional Energy Consultants (APEC), Southern Illinois Chapter.

The team updates Excel spreadsheets monthly upon receipt of the hospital's energy bill to track and analyze energy consumption information, which is continuously shared with the facility engineering staff. They also update the hospital's Portfolio Manager data monthly to compare their hospital's energy use with others.

Communications:

To communicate to employees about their energy efficiency successes, the energy management team included information about the ENERGY STAR label and energy conservation tips for home and work in the corporate newsletter. They also announced the award of the ENERGY STAR label with a display and handouts in the hospital's lobby. The team works with the local media to spread the word about their efforts.

Testimonial:

"Our ENERGY STAR label serves as a testimonial to our dramatic progress in energy efficiency garnered from our slow, incremental energy efficiency process. While energy saving improvements and behaviors were once major undertakings, they are now part of our standard way of doing things."
