The Future of Energy Efficiency in Off-site Construction

As we look forward on housing demand, how can we use what we’ve learned in energy efficiency over the years and apply it to the future of the building industry?
The Future of Energy Efficiency in Off-site Construction

When I take a look around the construction industry today, I admit I’m pretty surprised if a builder has not implemented some kind of energy efficiency standards into their building practices.  Of course, this was not always the case.  The emergence of many of the energy efficiency programs in the 80’s and 90’s were a direct result of the energy crisis in the 70’s.  Policymakers in Washington were motivated by a new level of environmentalism as efforts were made to reduce America’s dependence on fossil fuels.

A specific challenge drove the industry to work on solutions.

And even with the strides that have been made in the energy efficiency sector, it still remains far from perfect.  But that’s what progress is all about, right?  It’s solid, incremental changes, and constantly pushing the bar higher.

The most dire challenge currently facing the U.S. (and other countries around the world) is housing affordability.  Both in our inability to create it fast enough, and the inability to create it at an attainable cost for average income earners.  I’m not solely focusing on “low-income” housing, but it is alarming that over 11 million Americans pay more than half their salaries for monthly rent. This is an increase of more than 30% over the last five years.2

So what does all that have to do with energy efficiency?  Everything.  When you have a monthly housing budget that comes with an inconsistent energy bill, it can be unnerving.  Applying practical, energy efficiency standards helps make housing more attainable, but alone, isn’t enough to deal with the growing affordability gap.

Off-site construction methods (volumetric, panelized, etc.) have increasingly come into sharper focus as a viable solution for the housing attainability crisis.  But with that, we need to take what we’ve learned over the last 40 years in the energy efficiency sector and figure out how to utilize factory methods to make off-site constructed housing as efficient as possible.  And we need not stop at energy efficiency.  With factory methods, we have an opportunity to utilize technology, and its data, in a way that has never been done before.  For the foreseeable future, builders will be looking at HOW they build (off-site) relative to WHAT we build (energy efficient and sustainable products).  Off-site construction affords an opportunity to rethink energy efficiency.

The National Renewable Energy Lab (NREL) recently announced a 3-year project where they will be partnering with Factory OS (Mare Island, CA), Vaughan Buckley Construction (Philadelphia, PA), and Full Stack Modular (New York) to look at how to maximize energy efficiency in the factory process.

“As the emerging off-site modular sector continues to expand, we are seeking to embed energy efficiency and grid-interactive building concepts into the factory design, construction, and assembly process,” says Shanti Pless, Senior Research Engineer at NREL.  “We see a big opportunity to meet the challenges of affordability and low energy costs in the multifamily sector through the integration of high performance building strategies into the advanced building manufacturing industry.”

In addition to partner-factories, the project is also forming an Advisory Board whose purpose will be to provide guidance and technical support for the project as well insight and support for the development of modular industrialization standards that will be shared with other industry players.  Members of the Advisory Board will include players from technology integration, data/software, systems, building envelope, site assembly, automation/advanced manufacturing, codes, and standards.

The Need for Energy Automation

The Need for Energy Automation

As various states around the country amp up the use of renewable energy sources, the structure of the electricity grid will continue to morph into a system that sustains more and more automation.

Blake Richetta and Olaf Lohr of sonnen Inc. wrote: “The challenges posed by the intermittent and unpredictable nature of renewable energy on the electricity grid are well documented and include the monumental task of connecting renewable generation, at the specific time that it is generated, with energy demand. Additionally, renewables put considerable strain on the electrical grid from a voltage and frequency regulation perspective.”

Distribution automation (DA) technologies surrounding smart grids have been around for a while and are continuing to advance as energy systems are increasingly being inundated with distributed resources. The increase in natural disasters creates a greater need for grids that are resilient in extreme weather events, making the need for distribution automation even more important than ever.

Designed to help predict energy demand and mitigate issues on the grid, DA brings together software, sensors, and switches, integrating diverse sources of electricity and identifying when events such as power outages occur.

As we plunge deeper into the fourth industrial revolution we’ll continue to see more and more energy automation as we shift from the simple digitization seen in the Third Industrial Revolution, to technology that will force companies to collaborate and reexamine business-as-usual.

What interesting trends or innovations are you seeing in distribution automation?

The Flashing Yellow Arrow

Ongoing education is essential for keeping up with what's going on in your industry, and not getting stuck at that blinking light.
The Flashing Yellow Arrow

Back in 2013 I was working on a project in Tucson, Arizona. One day as I was driving around town, I got into a left turn lane on a green light and waited for an opening. To my surprise, the light went from green to a flashing yellow arrow - something I had never seen before. Cars were honking behind me and I just sat there while the light turned red.

If you’re judging me right now, go ahead. To my defense, I grew up on an island that had ZERO stop lights and only a handful of stop signs. I later discovered that the Federal Highway Administration had passed some type of ordinance in 2009 “authorizing the use of flashing yellow arrows nationwide.” And just so you know, there are areas in SW Louisiana that JUST made the switch in late 2018.

Later that same day while reflecting on that incident, I knew I should have instinctively known what to do on that flashing yellow light. But it also made me think...driving is something I did almost every single day but I hadn’t studied or read up on the changes in driving laws since Driver’s Ed (over 20 years earlier at that time). I wasn’t as knowledgeable as I should have been.

In a recent article from Builder, the author referenced a 2018 survey where 31% of home builders said their biggest challenge in constructing new homes to meet energy code was cost. Additionally, 10% of those surveyed responded that their biggest challenge was dealing with the airtightness of a home: “Builders described issues with airtightness of homes ranging from inability to meet current air change requirements, to those believing building homes ‘too tight’ introduced moisture or ventilation issues, particularly in very humid climates.”

The author then stated, “I would suggest that a deeper analysis of this issue will find that a lack of training and education about energy-efficient building practices as the primary reason that cost is a challenge for builders in meeting the energy code.”

Many of you reading this might agree with that statement. While we’ve seen energy efficiency become more and more standard over the years, there is still an enormous opportunity to educate our industry. I didn’t study up on the changes in traffic lights back in the day, but I do wish I had had someone there to walk me through that flashing yellow arrow.

With a mission “to advance and disseminate building science knowledge in the residential new construction community via education and collaboration,” learning is the very core of what EEBA is all about. So the next time you’re attending an educational event, consider bringing along a builder or other industry professional who might benefit from what you’re learning. Or, offer yourself up as a free resource for people who are wanting to become more knowledgeable in a particular area you have expertise in.

Let’s get that 10% lower and help guide someone through their flashing yellow arrow.

It’s All About People

It’s All About People

Back in the early 2000’s I was working as a Limited Practice Officer in Washington State. The real estate market was on fire and we couldn’t close deals fast enough. Realtors were pulling in huge commissions and lenders were having a hay-day. As we crept closer to 2008, home and land prices were becoming ridiculously high and I remember wondering why, and how, people were obtaining so many 2nd and 3rd mortgages.

I recall a few instances when buyers were signing documents and would say something like, “Well, I sure hope I can afford my utility bill after this.” They were joking at the time, but upon receipt of that first bill, many may have quickly realized they actually couldn’t afford the house they had just purchased, in addition to the utility bill that went along with it. By law, as a neutral third-party we were not allowed to advise buyers and sellers on anything except to tell them if they had concerns they should talk to their realtor or lender.

After leaving that side of real estate shortly after the crash, I shifted a bit and have since had the privilege of working alongside and learning from some of the most knowledgeable and forward-thinking people in the building industry. Sustainability and energy efficiency are seen now more as a standard rather than a revolutionary idea - and that’s due to the consistent work of all of you out there who have pushed the dial forward for so many years.

I was recently chatting with a new modular construction company that decided to implement IAQ and energy efficiency standards in their designs. As I sat listening to the person talk passionately about their goal of providing healthy, affordable living conditions for their customers I remember thinking: This is what it’s all about. People.

Life is busy. Doing what we do takes time. Changing long-standing “systems” can seem daunting, but if we can keep our eye on the purpose of why we are doing what we do, it will always be worth it. It’s ultimately for the people who will be living in those homes. Our knowledge, our innovation - it’s only useful if it benefits people.

Let us know what changes you are looking to see in our industry in 2019? And don’t forget to Save the Date for this year’s High Performance Home Summit in Denver (October 1-3).

Giving Thanks in 2018

What a year it has been! I think most of us can agree that 2018 has had its share of industry ups and downs, but there are many things for which to be grateful. In this week of Thanksgiving, the EEBA staff takes a moment to convey what they are most thankful for.

“Reflecting back on this year, I am truly thankful for the inspiring leadership of our President Gene Myers, whose time and dedication to EEBA have been invaluable, and for our incoming President, Geoff Ferrell, for stepping up and taking on this important role. I'm grateful for a very good year for EEBA, including a highly successful Summit, the many training events we've held across the country, and the partners, presenters, sponsors and board members who make it all possible,” says EEBA Executive Director, Nancy Bakeman, who has both professional and personal topics for which to be thankful.

“I am also grateful for my small but mighty team, as well as all the new people we've worked with this year, whose contributions have made a significant impact. And on a personal level, I am beyond excited to become a grandma next year, with two grandbabies on the way!”

Jill Lindman, Conference & Program Administrator, adds: “I am thankful for being brought into this incredible organization through my friendship with Nancy Bakeman. The leadership she has brought in her role as Executive Director has been a game changer for EEBA. We are a small staff with a big mission...I think we do it well!”

Finance Director, Cristen Burrell, recognizes the progress the high-performance industry has made in the last 15 years and is thankful for greater public awareness and understanding that better homes are available.

“Because of increased code requirements and the enforcement of basic building science principles and strategies, like proper insulation alignment and air sealing, families are getting healthier and more energy efficient homes, as a standard,” says Cristen. “I am so thankful for the hard work and dedication of volunteers across the industry that donate time and expertise to continue moving the home building industry forward. I am also very thankful for good food and great friends!”

Wishing all our friends and colleagues a wonderful holiday season with their loved ones, and know that all of us at EEBA appreciate each and every one of you!

Energy Efficiency Affordability in Cold Climates

A Canadian design-build team proves that energy efficiency is attainable, even in cold climates.
Energy Efficiency Affordability in Cold Climates

When Emmanuel Cosgrove and Mike Reynolds, co-founders of Ecohome, designed and built The Edelweiss House, they were simply trying to exhibit that affordable, energy efficient homes are achievable. “We undertook this project to show builders and homeowners that it isn’t that hard or expensive to build better-performing homes and that your true monthly overhead can actually be lower, right from the moment you move in.”

Building a hyper-efficient cold-climate house 40 minutes outside of Ottawa, Ontario, Canada, in Gatineau Hills, had its own challenges because of the climate and the nature of the location. Add in the standards required for Canada Green Building Council’s LEED v4 certification, and the challenge is amplified.

The resulting 1,552 sq. ft. passive solar home, where a visitor to Gatineau can rent a room and stay in, costs less than $250,000 to build, and energy bills were estimated to be less than $1.40/day, compared to a new home of comparable size that uses around 10 times more energy. To meet the stringent demands of LEED v4, Cosgrove and Reynolds used an array of DELTA® brand products from Dörken, together creating an airtight building envelope.

Fully adhered DELTA®-VENT SA, a vapor-permeable, self-adhesive, water-resistive air barrier for commercial and residential use, was used as the primary air and water-resistive barrier and helped the home pass difficult blower door test standards.

DELTA®-FLORAXX was used as the water retention and drainage component of the green roof and helped reduce the need for irrigation, while also helping to cool the building in the summer through transpiration.

DELTA®-VENT S served as the secondary moisture barrier and was installed to the exterior of the continuous stone wool insulation, providing additional airtightness, protection from moisture ingress, as well as insulation protection from wind-driven rain.

DELTA®-MULTI-BAND tape helped ensure that every lap and detail was sealed tight. It also played a critical role in maintaining an airtight building, along with a vapor-tight one because it was used to seal the interior vapor barrier.

The Edelweiss House was completed in 2015, and was only the second in the world to reach the rigorous Platinum level for LEED v4. The project really proved that affordable, cold-climate, energy efficient homes are possible.
