Commissioning professionals, myself included, have always advocated the delay of systems acceptance by and turnover to the owner until the commissioning process is complete. In this sense, “complete” means the systems pass their functional performance tests and the owner’s operations staff has been properly trained.
As the saying goes, the journey of a thousand miles begins with one step. On a data center project, some tailored software can often point things in the right direction. Novices and grizzled veterans alike would be wise to peruse some of these options for maximizing their new construction and retrofit results.
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.
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.
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.
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.
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.
Emergency generators are required in many applications where facility operations are to continue to perform even upon a failure of the electric grid. The best resources for quantifying the emergency generation classifications, capacities, installation, maintenance, and operational testing requirements are the building codes and federal regulations.
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.
Retrieving every last bit of performance from the system while stopping short of the surge line is no small feat. Dig into sizing, tower selection, chilled water loads and stability, and condenser water management to leave no efficiency stone unturned. Read more in April issue
