My business partner, Matt Napolitan, and I each spent 10 years working at major, international engineering firms. I worked for Syska Hennessy Group (11^th nationally ranked) in their San Francisco office and Matt worked for Buro Happold (14^th nationally ranked) out of their New York office. We now operate a 12-person engineering consulting firm in Burlington, Vermont. We know both large, big-city engineering and local, Vermont engineering.

The title of Project Coordinator, as well as Project Manager, is ubiquitous in most industries, but also rife with preconceptions that stem from an individual firm or team’s experience with the role. I was hired at Cx Associates as a Project Coordinator, filling a position that had existed before my arrival. My role was 1/3 Project Coordinator and 2/3 administrative support for at least a year. As a Project Coordinator, I learned how to coordinate measurement and verification of incentivized energy efficiency projects, among other things.

Commissioning of mission-critical data center systems is essential to ensure highest system availability through different phases of operation – at the outset of operations, down the road at full system buildout, and, later, when systems begin to age.

Lighting control systems have become more ubiquitous in recent years. Whereas five years ago, sophisticated lighting control schemes were the realm of a few performance venues, nowadays your neighborhood grocery store uses wireless lighting controls that can be complex to calibrate and require attention to detail from design through to occupancy. Commissioning is vital to ensuring that installed equipment operates as designed and provides adequate light levels and indoor environmental quality, and user controls function as intended.

Forty years ago, the practice of commissioning systems to ensure buildings deliver functionality and comfort for owners and users originated in Canada. Twelve years later, ASHRAE debuted Guideline 1 for the commissioning (Cx) process. For twenty years, the U.S. Green Building Council has included commissioning in LEED documentation, and in 2014, LEED v4 was released, requiring fundamental Cx, including design review, for all new construction projects seeking certification.

During this recent cold-snap in the northeast, you can be sure that HVAC contractors were some of the busiest people around. Inevitably, when outdoor temperatures reach what are called “design-day” conditions, (the days with the highest expected heating or cooling loads a building can experience for its local climatic conditions), HVAC systems are put to the test. It is not uncommon for problems that are not obvious at lower temperatures to suddenly arise - sometimes leading to system outages, frozen pipes, and worse - exactly when you need your HVAC system the most.

As buildings become increasingly complex and codes require more verification of performance, commissioning is as valuable as ever. “Savvy building owners recognize the gaps in the current design and construction process and the impact they have on the ability to achieve increasingly higher performance requirements” said Ryan Corker of the National Institute of Building Sciences in a November 2017 roundtable for the ASHRAE Journal. The Journal Editor asks: “Why is commissioning necessary if we have professionals designing buildings…shouldn’t everything just work correctly?”

I’m writing this blog from the floor of the Andover Public Library in Andover, MA. After a major windstorm, power is out all over New England and people are scurrying for the few available power outlets and sources of internet.

Previous blog posts from my colleagues and I contain a detailed explanation of functional performance testing (FPT), an overview of how functional performance tests are created, and specific examples of how conducting FPT contributes to better building performance and energy savings.  In this post I would like to expand upon the previous post “Functional Performance Testing Done Right: Details Matter.”

Commissioning agents do a large amount of review of other people’s work and products.  The building commissioning (Cx) process is a quality-assurance process for verifying and documenting that the performance of facilities, systems, and assemblies meet defined objective criteria^[1].  Therefore, to verify facilities and systems, I need access to a product’s technical documentation.  In the commercial building space, almost all documentation is online and readily available via a quick Google search.  Notice that I said almost.
