Years after an HVAC engineer starts to design closed-loop water systems and then progressively moves up the ladder of engineering success, he can forget and/or overlook many of the issues, concerns, details, opportunities, etc. associated with engineering these systems.
After 40 years and other engineering studies, a large university building still suffered from humidity problems. Our intrepid author dug into the data and the dark corners of the building in pursuit of the culprit — or culprits?
The Houston Methodist Hospital in Houston, TX, comprises over 5 million sq ft and includes a central utility plant, steam production, and CHP capable of producing 14,800 tons of chilled water capacity.
Today, many state institutions of higher learning and healthcare facilities face reduced budgets, aging infrastructure, and rising energy costs. According to the EPA, colleges and universities spend close to $2 billion each year on energy. These institutions are seeking innovative ways to renew facilities, improve energy efficiency, and reduce energy costs. One option gaining some renewed momentum is the Energy Savings Performance Contract (EPSC).
Pharmaceutical giant GlaxoSmithKline faced some extreme dehumidification requirements for its facility manufacturing denture-cleaning tablets. The strategy it selected not only reached target humidity levels but also allowed a 3º increase in chilled water temperature. Get the details on the system and savings that put smiles on the faces of this project team.
Texas Women’s University found that continuous energy monitoring and verification paid off well, yielding savings above and beyond an existing performance contract. The authors explain how measuring and managing can defeat the usual suspects that drag down plant performance. Is yours hiding some untapped greatness?
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
