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?
A 70-structure campus at the top of the Mississippi has been in need of a serious retrofit. We join this major project in progress, studying not only the design selections but the tradeoffs and sacrifices along the way.
Engineers are rethinking the standard engineering design paradigm, using lifecycle cost analysis (LCCA) to compare system alternatives that fulfill the same functional requirements but differ in terms of initial and operating costs.
The old saying goes, “Killing two birds with one stone.” But what if you could kill six with one stone? That’s what Abdul Momen, associate director of maintenance and operation for the facilities department at Georgia State University, aimed to accomplish at the school’s 216,000-sq-ft Natural Science Building.
With fluctuating energy prices, Loma Linda University searched for a cooling solution that would benefit the sprawling campus. Three different thermal energy storage systems were analyzed to find the best fit.
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.
