In this time of global crisis, it can be hard to cope with some of the new realities we’re all being faced with, whether it’s experiencing isolation due to social distancing, fearing for yourself or loved ones, or dealing with the virus’ economic impact. As a business that strives to engineer a future where buildings are better for people and planet, we can’t help but notice the ways this crisis reflects global warming’s looming themes: it’s going to affect everyone, it has dangerous consequences, and it takes a global effort to combat. While I only have the emotional bandwidth for one global emergency at a time, the environment is still in the back of my mind, and I can’t help but think of the ways the virus and our environment are inextricably linked.

Five Steps to Turn the Tide on the Climate Crisis
By Jennifer Chiodo on Mar 25, 2020 10:00:00 AM
I’m very focused on the fact that we have only have a short time to change the way we live so that our planet can survive, and our children can have the future we imagine for them. That sounds scary, but what is even scarier is inaction in the face of compelling evidence of climate change.

How to Do Building Automation System (BAS) Graphics Right: Part I
By Rick Stehmeyer on Mar 4, 2020 10:00:00 AM
Over the course of my career I have evaluated BAS graphics packages as a function of my daily 9 – 5. I have been doing this since 2002 and in those days, most BAS manufacturers barely had functioning websites. However, the products they sold allowed their vendor networks to create Human Machine Interfaces (HMI) and Graphical User Interfaces (GUI), and these interfaces haven’t really functionally changed a whole lot since those days of pre-broadband internet and before the smartphone was commonplace. Given that we may be stuck with outdated user interfaces for some time to come, it makes it all the more important that proper care is given to how the information is displayed and to ensure users can easily absorb the information they need from the BAS.

Energy and Beer – The Path to Sustainability
By Krystina Kattermann on Jan 29, 2020 10:00:00 AM
Vermont is home to a lot of my favorite things. There’s skiing, swimming, music, cheese, apple picking, and more, but perhaps my favorite is Vermont beer. The Burlington area alone has enough breweries to keep one busy for a long weekend – from the classics like Switchback Ale and Fiddlehead IPA, to the ever rotating sours at Foam to the delicious (and highly creative) concoctions coming out of Burlington Beer Co., the 10 mile radius around this small city I call home has something for everyone. Though my love of beer continues to grow, so too has my concern about the sustainability of the beer brewing process.

Challenges with Rooftop Units and Factory Controls
By Jamie Hand on Jan 15, 2020 10:00:00 AM
After an early morning departure and a snowy drive, my colleague and I arrived onsite to test, among other equipment, a packaged rooftop air handling unit with factory controls. At first, the unit appeared to check all our boxes, but as we dug into the details, it became clear that this would be a very expensive heating system to operate. This blog entry is about factory controls and the importance of getting into the weeds to identify issues like the one we found with this rooftop air handling unit.

Welcome 2020 - Now Let’s Meet those 2030 Goals!
By Katie Mason on Jan 6, 2020 10:00:00 AM
With a new year and a new decade upon us, the popular trend is to create new resolutions and goals. Being an active member of the Burlington (Vermont) 2030 District Engineering Team has me thinking about the District’s and the City of Burlington’s goals and progress for energy, water, and transportation emission reductions. This post outlines what the Burlington 2030 District goals are, how these compare to the City of Burlington goals, and the services our team provides to property owners to help reach these goals.

Making Sense of Building Data: Part 1: Overview
By Daniel Tuhus-Dubrow on Dec 18, 2019 10:00:00 AM
Similar to other domains, data from buildings is being generated at an unprecedented pace and scale. However, all of that data is useless if we can’t extract meaning to create value and yield actionable insights. This requires the utilization of protocols or standards to effectively make sense of the data. Project Haystack is one such standard that has been developed over the past several years and allows for the contextual tagging of data in a flexible way, using data from any number of sources.

It’s All in the Lighting: A Closer Look at the CRI Method
By Wilson Yandell on Nov 20, 2019 10:00:00 AM
A few years ago, while living in a small apartment in Montreal’s Plateau neighborhood, I noticed that the lightbulb in my kitchen had burned out. Naturally, I went to the hardware store to find a replacement. After struggling to read the French labeling on several different packages, I ultimately decided to go for the least expensive box of LED bulbs that the store had available. Once I installed the newly purchased lightbulb, I noticed a difference in the way our kitchen looked. Specifically, I noticed a difference in the appearance of the bowl of fruit that always sat on the counter. While the lightbulb illuminated the space, I remember thinking to myself how unappetizing and dull my fruit now looked. This exercise, though unintentional, clarified the importance of a light source’s color rendering capability.
