Incorporating a plenum can have its design advantages, but corridors serving adjoining areas of health care occupancies are prohibited from being used for a portion of an air supply, air return, or exhaust air plenum. This article and its illustrations can strengthen your grasp of the related NFPA code details and exceptions so you can design and ventilate properly for this special population.
Whether your client has a school or office building, desiccant dehumidification can successfully control the project’s humidity, save energy, and remove pollutants. This primer empowers you to teach your clients how desiccants work, while other tips and applications can help your future projects more than make the grade.
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.
A VRF system installed in this University of Hawaii dorm helped the school achieve LEED® certification and lower energy costs. Founded in 1907, the University of Hawaii at Manoa (UH-M)
As noted in last month’s column, accessibility
to mechanical, electrical, and control system components is critical for
sustainable systems operation. However, the design and construction industry is
sorely lacking when it comes to agreeing on what appropriate accessibility
means. In order to make a meaningful difference in how systems are delivered to
owners/operators, it is critical to define measurable accessibility acceptance
criteria early in the design phase and allow the commissioning professional to
shepherd that criteria through the design, construction, and acceptance phases.
For a consumer food group’s very mixed-space campus, HGA’s careful outdoor air strategy got support from smart boiler, chiller, and lighting design to create performance tailored for the client while comfortably exceeding LEED®and ASHRAE 90.1 requirements.
Most of us think of data centers when we think “mission critical,” but
the category goes into financial and health sectors as well. These
five phases of commissioning can provide some additional peace of
mind about performance, no matter which type of critical mission is
at stake.
