When you have to individually go verify whether 128 air curtains meant to ensure air balance in the original design’s branch ductwork are still there or not, you’re not having an easy time of it.
Geothermal and VRF components, along with a key design revision and even an underwater heat exchanger, buoyed this project as it sailed toward a flexible and sustainable finish.
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?
Combustion air, ventilation, piping, expansion tanks … with these and other factors affecting performance and safety, the boiler swap is not exactly a plug-and-play situation.
Designing a commercial boiler replacement where you were not the original designer or installer might have some hidden dangers that could haunt you for years.
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.
