CAD IC Documents vs. Court IC Documents

Find out how CAD can play an important role in infection control.
Howard McKew, P.E., C.P.E.
July 8, 2016
Probably a year before 9/11, I was asked my thoughts along the lines of, “What else should we commission beyond the standard building systems?” My client was the project engineer at the Department of Defense in the Pentagon. I suggested “commission project record drawings.” I guess you could say I made up the task of commissioning record drawings, but I got my point across.

IAQ In Review

Brush up on outside air, intake placement, critical environments, construction and renovation, and VOCs.
Michael Gilmore Paul Luster
July 7, 2016
Good IAQ management has become paramount in the construction industry, as study after study shows that employee productivity and health are directly related to the quality of air being delivered inside the workplace environment.

BAS Commissioning Basics

Does your control systems “work” or does it operate as designed?
Paul Ehrlich P.E.
July 6, 2016
A few months ago, this column covered the basics of developing effective control system sequences. You might recall that it discussed the process of how a designer needs to select and describe sequences that provided safe, reliable, and efficient control.

Commissioning: Integrated Project Delivery

Done right, IPD can rescue good ideas and avoid the far-reaching consequences of some common errors.
Rebecca T. Ellis, P.E.
July 5, 2016
Integrated Project Delivery (IPD) is a collaborative process that has been applied more and more frequently to building design and construction projects. Although it is implemented in slightly different ways from project to project, it is always about involving all project team members in intense planning and coordination, starting very early in design and extending through construction and facility turnover.

Emergency Generators In Health Care: Diesel Or Natural Gas?

More specifically, has natural gas been overlooked? Let’s take a look at some previous habits and code language, current needs, and the advantages that a CHP system can provide for those exceedingly regulated of all environments: hospitals.
Marcia Karr, P.E.

Localized Return Air Inlet vs. Value-Engineered Single Return Air Inlet

When it comes to air distribution, more diffusers is not necessarily better.
Howard McKew, P.E., C.P.E.
June 8, 2016

Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.

Building Automation & The Internet Of Things

As the Internet of Things continues to flourish, what will be the role of building automation?
Paul Ehrlich P.E.
June 6, 2016

There is a fair amount of press about the concept of the “Internet of Things” — or as it is commonly abbreviated, IOT. The concept of IOT is simply defined as a network of physical devices.

Cx: More On Responsible Parties

It’s less about placing blame than finding the right person to fix the problem.
Rebecca T. Ellis, P.E.
June 5, 2016

Continuing last month’s topic of commissioning action lists (a.k.a. master issues logs, a.k.a. corrective action lists), I would like to focus on the items in those documents that deal with construction phase or acceptance testing “deficiencies.”
