Here’s a task: bridge the new mechanical room to the utility connection in the old space - located in an adjacent building in Chicago’s South Loop. Room for equipment is frequently tight, but in the case of this steam pipe, the room for error was less than one inch. The kind of planning that navigated that challenge accounted for (almost) everything in this tricky retrofit.
approach they came in thinking about wasn’t the chiller plant
strategy they chose. However, it was twice as efficient as the
piecemeal system that had evolved over the years. Modern planning to
minimize changeorders and navigate tight fits - plus smart choices
from valve selection to installation tactics - comprise a star HVAC
exhibit in this Chicago museum.
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.
