The Importance of the Project Coordinator Role in Building Commissioning

Posted by Rachael Straub on May 9, 2018 9:50:00 AM

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.

Rack-Mounted Load Banks for Data Center Load Testing

Posted by Ben Fowler on Apr 11, 2018 3:04:41 PM

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.

The Right Light for Your Building: Designing and Commissioning Wireless Lighting Controls Systems 

Posted by Gretchen Schimelpfenig on Mar 28, 2018 3:21:54 PM

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.

2018 Resolutions: Goals for the Building Commissioning Industry

Posted by Gretchen Schimelpfenig on Feb 7, 2018 11:15:00 AM

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.

Using Opposite Season Testing to Protect the Integrity of Your HVAC System

Posted by Ben Fowler on Jan 17, 2018 9:07:00 AM

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.

The Role of Commissioning for Industrialized Construction Projects

Posted by Gretchen Schimelpfenig on Dec 6, 2017 2:52:00 PM

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?”

Designing Buildings for Resiliency To Accommodate Power Failures

Posted by Jennifer Chiodo on Nov 1, 2017 10:00:00 AM

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.

The Importance of Functional Performance Testing BAS Outputs

Posted by Walker Calderwood on Jul 12, 2017 10:00:00 AM

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.”

The Advantages of Publicly Accessible Controls Documentation

Posted by Rick Stehmeyer on Jun 14, 2017 11:00:00 AM

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.

Lighting Control Systems and the Double-Edged Sword

Posted by Rick Stehmeyer on Apr 26, 2017 10:00:00 AM

Lighting control systems are making their way into new construction and are becoming as common place as HVAC controls.  Just like with many new building technologies, lighting control systems started small, and are now gaining more and more market penetration.  This is great news for those of us who work towards saving energy for building owners.  This new frontier of controls creates new challenges for those of us who work towards saving energy for building owners.  Why, you ask?
