Take a large hospital, subtract unexamined rules of thumb, add meaningful incremental improvements like VFD’s and a controls upgrade, and what do you get? Smarter engineering via improved performance for both the pumps and the chillers. But it all starts with one little question.
Whether your system uses boiler steam or another method, the authors walk you through the pros and cons of various sytems, the evolving standard landscape regarding those corrosion-fighting amines, and some energy reduction ideas.
Most companies want to decrease their energy consumption, either for financial reasons, or to be active in reducing their carbon footprint, or both — but some of them aren’t sure where to begin. When the only measure of a facility’s energy usage is the bill customers receive at the end of the month, they may feel their facility is more like the proverbial black hole: power goes in, business happens inside, but it’s not clear exactly how much energy is used where and when.
“Quality of care” is more than just a phrase at Carilion Roanoke Memorial Hospital (CRMH), one of the largest hospitals in Virginia. CRMH defines quality of care using six characteristics: excellence in care, patient safety, clinical outcome, technology advances, accessibility, and patient experience.
How many energy-efficient or certified buildings are not living up to the label? Very, very many, if this Ohio commissioning/auditing firm’s experience is close to typical. They report on common weaknesses in efficiency strategies and on real-life patterns of upgrades gone wrong across an array of equipment types. While flaws in well-intentioned processes remain, a more careful investment of human energy can still yield the desired reduction in building energy.
Done right, going modular can be a good fit for hospitals in search of efficiency. From design to specification to pre-shipment, the process demands engineering attention to the right details at the right times. Get a designer’s notes from experience and learn how to take advantage of what a modular central plant can offer.
What are the key technical challenges and design options for optimizing a geothermal heat pump design? Review the pros and cons involved with centralized or distributed pumping, with hybrid or decoupled systems, and with the controls that can guide them.
Today, commercial property owners and facility managers are constantly looking for ways to reduce their utility bills. An often over-looked opportunity arises when it is time to replace old, inefficient compressors in HVAC systems.
