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.

Earthquakes and strong gusts are threats in the physical world that creep into the HVAC design world of isolators, supports, and special louver considerations. Furthermore, a new legal world in terms of codes, insurance, and liability can leave inattentive engineers, owners, and manufacturers quaking in their boots. Read on to stay safe in more ways than one.

Increasing energy awareness as it relates to the server farm can be a hard row to hoe.

There’s a concept, eh? The author takes a comparative discussion of chiller technologies and options, and he places it squarely within the current events context of domestic energy sources, the utility rate landscape, and thermal efficiency. Read this and then look for Part 2 in the near future.

Low emissions, footprint help hospital make strides

Terminal devices, pressurization, supply air, proper exhaust … those factors and more go into a well designed VAV system for sensitive lab applications. From general tips to changing details such as fabric duct elements, booster fans, and a new AMCA standard, the author equips you to succeed in one space that is no place for experimentation.

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.
