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.
A few circumstances in a data center make it ripe for a CHP design to boost efficiency. Let’s get into the options within both relevant chiller types, why payback may be shorter than expected, and the assorted potential benefits from lower costs to higher reliability. Some tips from an array of manufacturers’ reps round out this useful investigation.
It’s not necessarily a plug-and-play situation, but these chillers can play key roles and deliver meaningful savings in several scenarios. Waste heat, CCHP, standalone, and even renewable solar as part of the refrigeration cycle can all provide the setting for absorption success.
This law school design story moves on from rationales for early decisions to the specific next-phase design challenges. Team effort combines with DOAS, radiant ceiling panels, DCV, and setpoint fine-tuning to maintain this case’s appeal.
Perhaps the U.S.’s largest to-date Dedicated Outdoor Air System (DOAS) coupled with radiant ceiling panel (RCP) cooling and heating mechanical system is currently under construction at the Washington College of Law at American University (Washington).
The federal push toward break-even building energy is real, and the clock is ticking. The public sector will be flocking toward forward-thinking designs (and designers) like never before — prepare to rule more of the roost, or lay an egg.
These days, designs are favoring higher total system capacities, larger generators at higher output voltages integrated into “campus-type” power distribution systems, and security. Review design approaches, lessons learned, and relevant codes.
