The Challenge of Decarbonizing the Grid

By Rachael Straub on Jan 24, 2024 9:30:00 AM

Cx Associates is a mission driven energy engineering firm that works with buildings, mostly Commercial and Industrial buildings, and one of our central missions is to be part of the solution to climate change. Professionals in our field understand the challenge we’re facing. The Biden Administration National Climate Task Force has set the goal of a 100% net-zero emission economy by 2050. To meet this goal, we need to decarbonize the grid, but renewables account for just 13% of electricity generation in the U.S. While that’s close to a tripling of levels a decade ago, we still have a long way to go.

Onboarding with Purpose

By Eric Hauser on Aug 2, 2023 10:00:00 AM

Have you ever started a new job and your first day goes something like this: You arrive, and no one was expecting you or realized you were starting that day; you didn’t have a workstation set up; no one knew how to get into your computer; there was no work for you to do; and no one knew which forms you needed to complete to get you enrolled in benefits, payroll, etc.?

Striving for Net Zero: Part II

By Krystina Kattermann on Jul 12, 2023 10:00:00 AM

Over the last few years, climate action has become a central focus for governments, and the business case for doing something about climate change has become clearer than ever before. With this shift, “Net Zero by 2050” is a term that seems to get thrown around by organizations, businesses, and municipalities alike. But what does it mean, and how do we get there? We continue our endeavor to answer this question in the second part of this two-part blog.

The Case for Hourly Emissions Accounting

By Daniel Jordan on Jun 7, 2023 10:00:00 AM

Last month, at the close of Vermont’s legislative session, the House and Senate agreed to create a Legislative Working Group to investigate reforming VT’s Renewable Energy Standard (RES). This is a big deal because the RES sets the rules by which Vermont utilities claim their electricity is renewable. And now those rules might change.

Forgoing Band-Aids: Approaching and Fixing Building Issues Holistically

By Daniel Tuhus-Dubrow on Jun 28, 2022 10:43:00 AM

June 2022 update: Given the current supply chain and labor shortages the construction industry is facing in 2022, looking after your building's existing systems becomes even more important. With equipment delivery for major systems sometimes many months away, retrocommissioning your existing systems can help tune them up to keep them in tip-top shape to get more usable -- and efficient -- life out of them. 

When people ask me what I do for work, I generally tell them I’m a building systems engineer, with a big focus on making facilities more energy efficient and comfortable for occupants. One common part of my job entails going to a building to perform an energy audit or assessment. During these visits, we follow the same straightforward outline:

  1. Walk through the site
  2. Inventory all energy-related equipment including lighting, mechanical systems, building envelope, etc.
  3. Speak with the building operator about how they run the building
  4. Ask the building owner, occupants, and operator about and any issues or concerns they have regarding maintenance, equipment that is not working properly, or comfort problems.
Through these visits, we produce a report that documents not only the existing building systems, but recommendations on equipment upgrades or operational changes that can be made to save energy or improve comfort. We also provide quantification of energy and cost savings for each identified opportunity so that the building owner knows how much of a bang they get for their buck.

Our Journey Towards Equity, Diversity, and Inclusion

By Eveline Killian on Jun 16, 2022 11:00:00 AM

It has been two years since the latest onset of this country’s reckoning with the unequal treatment of Black and People of Color in our society. While the murder of George Floyd was a turning point for many, since then the division within our country seems only to be growing wider, with each ‘side’ becoming more entrenched and insistent in their perspective.

Decarbonization: Fight Climate Change with Your Building

By Daniel Jordan on Apr 26, 2022 11:00:00 AM

Your building’s climate impacts begin with every mechanical, electrical, and envelope system on which it’s built. Identifying effective greenhouse gas (GHG) reduction measures requires an in-depth knowledge of a building’s systems and how they interact. That’s where our decarbonization service can help.

Blower Door Testing: Hand-in-Hand with Commissioning

By Mike LaCrosse on Mar 31, 2022 10:00:00 AM

In Vermont’s commercial construction industry, the word is well out there by now that the 2020 Commercial Building Energy Standards mandate building air barriers receive special attention, to some degree – either at post-envelope construction by way of a blower door test, or throughout the construction phase by way of commissioning (no blower door test). I’ve discussed portions of this in the past when it was relatively new. The 2021 IECC release now also mandates either air barrier commissioning or blower door testing. It will be some time before states begin to adopt this version of the code, but it is only a matter of time. So, I thought it a good idea to get out ahead and discuss why I think we, as an industry, should be considering the two of these options in harmony, rather than separately.
