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
A fog humidification system installed at this Michigan lab is controlled by a BAS.Pall Life Sciences is a leading global provider of filtration, purification, and separation technologies to the diverse
VFDs and a new chiller reduced this Texas hospital’s carbon footprint. With large central utility plants, over-taxed HVAC systems, and ever-increasing utility costs, many hospitals face the dual problems of
School districts have known for quite some time that temporary equipment can assist in passing the tests of renovations or the pop quizzes of unexpected equipment failure. The lesser-known lesson is that having the plan in place can save significant time and money on top of the equipment’s basic benefits.
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.
