OPR: The Underappreciated Path to Success

By Jennifer Chiodo on Oct 10, 2018 12:00:00 PM

 

I looked back through our blog history and realized I have never written about the importance of a lovely little document called the Owner’s Project Requirements, or OPR for short.  An OPR is created through collaboration with many involved parties; it synergizes everyone’s ideas into one goal-focused document. At Cx Associates we are such believers in defining the goals and criteria for project success that we often develop OPRs even for internal business improvements to help focus and guide the process.

Why Design Review Is Crucial

By Thomas Anderson on Aug 29, 2018 10:00:00 AM

We often hear a question that goes something like this from building owners: “Why do I need an independent design review? I hire the best architects and engineers.” It’s a reasonable question — asked so often in my opinion because those of us in the architecture, engineering and construction industries have done such a poor job answering.

The Case for Small, Local Engineering Firms

By Jennifer Chiodo on Jul 26, 2018 4:29:30 PM

My business partner, Matt Napolitan, and I each spent 10 years working at major, international engineering firms. I worked for Syska Hennessy Group (11th nationally ranked) in their San Francisco office and Matt worked for Buro Happold (14th 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 Importance of the Project Coordinator Role in Building Commissioning

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

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 

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

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

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

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

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.
