The particular charms of panels, chilled beams, and related options seem to be at-tracting more attention from designers and owners these days. Design, installation, and even architectural considerations can earn a hard look at radiant for a surpris-ing number of applications.
Leaning on experience and data from various K-12 cities and projects, the authors pursue 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.
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 Radiant Rollout™ mat is a custom-designed, prefabricated, pre-pressurized network of the company’s cross-linked polyethylene (PEX-a) tubing deigned for faster, more consistent installations for large commercial radiant heating and cooling applications.
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
