Building Energy Resilience

Given that we're solidly into football season, we thought it was a good time to revisit this post by Katie from last year about stadium energy efficiency. Enjoy.

After recently attending a New England Patriot’s football game at Gillette Stadium in Foxboro, Massachusetts, I was overwhelmed by the size of both the structure and the population density served during the four plus hours that the game is taking place. The relatively new Gillette Stadium is also a completely open configuration located in a cold climate. Unsurprisingly, my thoughts immediately turned to energy consumption and sustainability.

With the growth of the Internet and our undeniable dependence on electronic data, comes the reality that data centers are estimated to consume 1.5% of the total world power – and this continues to rise rapidly. Large data centers are certainly the drivers behind these numbers, but most small companies have server rooms or small data centers that, collectively, contribute to a significant portion of this country’s costs and environmental footprint. Outside the IT opportunities of virtualization and server consolidation, there are few things the facilities department and management of a business can do to reduce this overhead and environmental cost. But as with many things, if we all do a small part it will end up making a big difference.

I originally posted this in 2014. But, with Killington recently hosting a World Cup race in November, and given how much they relied on artificial snow, it seemed appropriate to bubble it back up. Snowmaking can be an extremely energy-intensive activity. With fewer solidly snowy winters, can skiing be sustainable [PDF]?

The 2014 Winter Olympics being held in Sochi, Russia are located at one of the warmest locations in the history of the games. Setting aside for now the slow creep of a warming climate, Sochi, located at the eastern shores of the Black Sea, is a humid subtropical climate with an average winter temperature of around 50F during the day and still above freezing at night. In the higher elevations in the nearby Caucasus Mountains, where the events are taking place, daytime temperatures still average above freezing during the day. So, while it is a far better location for the actual “winter” portion of the games than the palm-tree-lined streets of the city of Sochi proper, it still is not the ideal location to host the Winter Games.

I had hoped to share my recent sci-fi story about future decisions that might need to be made around a demand-constrained grid in the era of extreme heat waves and self-driving electric vehicles.  But, fiction is not the point of this blog.  If you want to receive a copy of the story, feel free to request it – we monitor comments.  In this post, I’ll discuss a little of the back-and-forth we’ve been having regarding the New England Grid [PDF] and demand constraints. 

As a follow up to my previous blog post on peak shaving, this week I’m going to cover demand limiting.  This is another peak shaving strategy that we are also using on the project I mentioned in my last post.  Demand limiting is different than energy storage in that instead of using the same amount of energy from different sources than the grid to peak-shave, the amount of energy being used is limited to achieve the same peak shaving goal.  I would like to note that there is no reason these two strategies can’t be used together - we are actually using both strategies on a current project to achieve the customer’s peak shaving goals.

Note: This is Part Three in a series of posts on RS-485. | Part 1 | Part 2

In part 1 and part 2 of this series on RS-485 we covered the basics.  Let’s take some of that knowledge and talk about what most often goes wrong with RS-485.  I want to give you the ability to red flag common mistakes and some knowledge that will help repair the most common issues.  I am going to take some of the knowledge we gained from the last two posts and put it into context for both existing RS-485 installations and new ones.   I’ll discuss this in the form of red flags that will trigger the discussion.

I recently attended the Health Care Construction (HCC) Certificate workshop in Seattle, Washington. This event, organized by ASHE (American Society for Healthcare Engineering) and WSSHE (Washington State Society for Healthcare Engineering), was directed towards contractors, facility managers and construction project managers in healthcare. ASHE offers many certifications, workshops and education opportunities for different audiences in healthcare. This post will discuss this workshop and a few points I found particularly important (there were many!). 

An Amendment to the Montreal Protocol

Last month, representatives from over 170 nations gathered in Kigali, Rwanda to negotiate and ultimately agree to an amendment to the Montreal Protocol—the landmark international treaty, signed in the late 1980’s, which led to the phase-out of the manufacture and use of ozone-layer-depleting chlorofluorocarbon refrigerants (CFCs). The 2016 amendment focused on phasing out hydrofluorocarbon refrigerants (HFCs) which, while safer for the ozone-layer than CFCs, are themselves very powerful greenhouse gasses with far more global warming potential than CO₂.

I fell asleep to a TED Talk while visiting New York City the other night, but a startling statement brought me back to consciousness.  New studies predict the oceans could rise by close to two meters (more than six feet) by the end of the century.  That’s double original estimates and only 83 years from now - in our kids’ or at least our grandkids’ lifetimes!

Energy efficiency program evaluation sounds so arcane, most people, I’m sure have no idea that there are large cohorts of people (cohort is a word we use frequently in evaluation) who spend their lives verifying the results, the savings, from energy efficiency programs.  Because energy efficiency program evaluation (evaluation hence forth in this blog) is outside the realm of day to day life, most of us are completely unaware it exists.  This post is about my vision for how evaluation and real life (in the commercial, institutional, industrial (C&I) building operations world in which I work) could intersect in ways that could make buildings, programs and evaluation better and lower costs for ratepayers.
