Managing solar loads and incorporating radiant ceilings were just part of the plan for this five-level mixed-use building. Chilled beams and chiller plant decisions joined ventilation strategy to serve both occupants and LEED ambitions.
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.
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.
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.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
