As someone very new to the engineering world, I’ve learned a lot in the last few months about the impact that engineers can have on climate change. I came to Cx Associates and the world of commissioning in a rather round-about way. My background is in molecular genetics, specifically lung cancer research, but when I moved to Burlington this past summer, I decided to pivot in my career path. I’d found myself desiring more and more to move into a field that was doing some good for the world. I know, I know, many would say “Hey! Cancer research is good for the world!,” and I certainly don’t deny that, but what good is finding new cancer treatments if there isn’t a planet that can viably support the patients those treatments would be for? As I’m sure many of you heard or read in the news some months ago, the Intergovernmental Panel on Climate Change (IPCC)’s 2018 Climate Report showed that “global warming is likely to reach 1.5°C between 2030 and 2052 if it continues to increase at the current rate” (something some climate scientists have argued is a conservative estimate). This will have devastating effects on people’s lives, and not only in poorer nations of the world – the Fourth National Climate Assessment released by the U.S. Global Change Research Program in November 2018 predicts U.S. economic losses due to climate change in 2090 as $280-$500 billion/year. These reports cemented my feelings in the weeks and months after I began at CxA, but I had already felt myself pulled towards the idea of working for a company or organization that was doing solid, on the ground work to combat climate change. I did not expect that pull to land me at a consulting engineering firm.
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:
- Walk through the site
- Inventory all energy-related equipment including lighting, mechanical systems, building envelope, etc.
- Speak with the building operator about how they run the building
- 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.
Retrocommissioning (RCx) or Existing Building Commissioning refer to a technical process that retrofits and tunes building HVAC control systems so that buildings function more efficiently and effectively. The RCx process has historically included three primary phases: Planning, Investigation, and Implementation.
Wilson “Snowflake” Bentley was born in my home town of Jericho, VT in 1865. The town is situated in Vermont in a unique way that allows for a lot of annual snow (by Vermont standards). Not only does Jericho get a lot of snow, but we also seem to be situated in such a way that we get perfect snowflakes that don’t clump together. This is what allowed Mr. Bentley to become one of the first known snowflake photographers. He invented his own way of catching flakes using black velvet so they wouldn’t melt or evaporate before he could snap a picture of them.
As the newest engineer to join the Cx Associates team, I have had the immense pleasure to be able to approach buildings from a different angle than in my previous work experience. In my former work as a mechanical design engineer, the focus was on current building technologies and keeping up with the most cutting-edge designs for our systems and buildings. Don’t get me wrong, looking to the future of efficient building technologies is tremendously important, but as someone who is concerned about the current state of the environment and ensuring there’s a habitable world for generations of living things to come, I found it hard to believe that new buildings alone are capable of being more than a small drop in a big bucket. After all, there are only a small number of new buildings built each year compared to the vast existing building stock. A quick look at the numbers from the Commercial Buildings Energy Consumption Survey (CBECS) by the US Energy Information Administration (EIA) will tell you that of the total data set, only about 18% of commercial buildings were built in the most recent 12 years surveyed.

Last week in part I of this post, I discussed the advantages of companies allowing some workers to work remotely, and what my transition to a remote worker was like. In this week’s follow up post, I’ll get a little more into the logistics of working remotely and flag some recommended practices and tools that have worked well for us.

In 2014, due to life and professional circumstances unrelated to my job as Operations Manager at Cx Associates, my wife and I relocated from Burlington, Vermont to Chicago, Illinois. Having worked for Cx Associates since 2009, I was reluctant to leave behind my job – I was happy there, the people I worked with were fantastic, and the work was meaningful and interesting. Luckily for me, when I approached the owners about the possibility of continuing to work remotely for CxA from Chicago, they agreed to let me stay on. I was ecstatic!

Space upgrades are necessary to ensure that older buildings remain safe, functional, and cutting-edge for the users. As part of my role as an owner’s project manager for a large hospital, one of my recent projects has been upgrading the finishes of several operating rooms. This post discusses the coordination and construction effort involved for such a project, as well as some potential challenges.
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.

The best time is now to replace an old R-22 refrigerant system with an environmentally-friendly alternative.
For better or for worse, we no longer live in the days of hairspray. Our ’do’s style may have suffered slightly, but our environment has benefited greatly. When the Montreal Protocol was signed by the United States in 1987, it set a goal of reducing emissions of ozone depleting chemicals, and it has experienced some success…I hope you all celebrated World Ozone Day this month on September 16th! Many people may be blissfully ignorant of the changes to their aerosol products in the last 30 years thanks to the Montreal Protocol, but in the HVAC/R industry, we’re continually aware.
