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).
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?
VFDs and a new chiller reduced this Texas hospital’s carbon footprint. With large central utility plants, over-taxed HVAC systems, and ever-increasing utility costs, many hospitals face the dual problems of
Smaller in size but big on style and service, this Boston hotel looked to compete with bigger brands by cutting costs behind the scenes. A chiller overhaul led the list of improvements, which included lighting and controls retrofits, and allowing rooms to recirculate air when unoccupied.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
