As always, NESEA’s BuildingEnergy Boston conference was filled with thoughtful discussions and lots of positive energy.

Two sessions that stood out the most were rooted in what attracts me to the NESEA community. The first was presented by Rachel White, CEO of Byggmeister Design/Build, and Michael Hindle, Principal, Passive To Positive, on The Deep Energy Retrofit Controversy Revisited. As a follow up discussion to last year’s keynote, Why We Stopped Doing Deep Energy Retrofits (presented by  Rachel with Brendan Kavanagh, Byggmeister co-owner), it sparked some lively feedback. The session was passionate, insightful, and thoughtful.

It was a perfect autumn day for the Yale Divinity School (YDS) Living Village Ground Healing Ceremony. IES team member Carlye Woodard was on hand  for the well-attended event, which launched the construction phase of this much anticipated project with discussion and questions, prayer and recognition, as well as food and drinks to mark the celebration. YDS Dean Gregory E. Sterling suggested, with a playful nod to Joni Mitchell’s iconic lyrics, that the school is endeavoring to tear up a parking lot and build a paradise.

IES’s Matt Root recently presented Better Materials Managed Digitally at the BE+ Building Tech Forum at The Foundry, Cambridge, MA. The theme was Accelerating Change in the Built Environment, with five-minute talks from a diverse group of innovators showcasing building technology advancing  this vision–including our own Red2Green materials management platform.

Charlestown’s Bunker Hill Housing Redevelopment project, which broke ground in June 2023 after an eight-year community planning process, promises 21st century comfort, energy efficiency and carbon reducing performance in its new mixed-income residential community. Located in an historic waterfront neighborhood, Boston’s oldest, much of this 1940s-era federal public housing site had fallen into disrepair. Now, in a public-private partnership, the team of Leggat McCall Properties and Joseph J. Corcoran Co., in partnership with the Boston Housing Authority and the Charlestown Resident Alliance, has developed and launched a $1.4 billion plan to replace 42 aging buildings with 15 new residential buildings, plus retail and community space. To strengthen the sense of community, the project features extensive green spaces and improved connections to the surrounding area.

The 2022 BE+ Green Building Showcase Award Winners

Both IES’s Charley Stevenson and Matt Root were honored to attend the BE+ 2022 event, which was hosted at Harvard University’s Science and Engineering Complex (SEC).

IES’s Charley Stevenson and Matt Root will be on hand as Built Environment Plus holds its 2022 Green Building Showcase on Oct. 27, 5-9:30 p.m. The event happens at Harvard University’s Science and Engineering Complex (SEC), the BE+ 2021 Green Building of the Year. IES was Living Building Challenge consultant for SEC, researching 5,600 building materials using IES’s healthier materials management platform, Red2Green. Join us for a night of project boards, presentations, discussions and awards for everyone involved in designing, operating and constructing the built environment, which is sponsored in part by Red2Green.

The details of better building are well understood, but when considering the variety of options it’s all too easy to get tangled with needless complication. Yes, parametric energy models provide cool visuals, but since we already know the basics, let’s take a look at some ways to increase performance and keep it simple.

Well-established strategies and ambitious but achievable metrics provide us with some key starting points. Every project and each project team is different, and we all know the devil is in, well, the details.

Here are ten easy steps, and we note that there is flexibility in all of them: 

  • Make it airtight: 0.10-0.15 cfm75/sq ft shell area
  • Detail continuous exterior insulation:
    • Aim for a true R15-20ish in the walls
    • Small things can make a difference—such as using thermally broken attachment clips
  • Ensure that there are no major structural thermal bridges
  • Stick to a modest window to wall ratio—24%ish is good
  • Look at higher performance windows
    • You don’t necessarily have to go to triple glazed, but doing so may allow higher window to wall ratios
  • Employ high efficiency air source heat pumps for heating and cooling
    • Air to water heat pumps are also worth a look
  • Specify 85%+ high efficiency ERVs
    • For residential units, ensure that fresh air is routed directly to each bedroom (as opposed to the return side of the fan coils)
    • Minimize ductwork on roof
  • Minimize the DHW loads
  • Location, location, location—and simple here means establishing the best possible building orientation for solar
  • Design for unit compartmentalization (0.30 cfm50/sqft)
    • Whole-building sealing is essential, but don’t overlook sealing up gaps between adjacent residential units

Of course every step won’t be applicable or achievable in all cases, but giving each of these basic ideas due consideration at the outset covers the essential factors for a high performance building.  When we begin a project by getting clear on the goals  and appropriate standards such as these, we provide valuable parameters—creating a solid framework that the design and construction teams can leverage to perform their finest work.

When asked to participate in the Living Future 2022 Conference panel presentation on the Volume Certification process IES developed with Williams College, I’ll admit I was skeptical about filling the allotted time with relevant information. Living Building Challenge (LBC) Volume Certification requirements had only recently been agreed upon, and represented a relatively small adjustment to IES’ overall process. The advantages of reusing compliant and audited products from a certifying campus project on subsequent campus projects seemed clear. Incorporating these previously researched and approved products into the campus standard just makes good common sense.

By shifting my thinking to the perspective of the audience—imagining an architect, CM, or college planning director just beginning the process of designing to LBC standards—I recognized that the process we have developed and the perspectives we have earned from multiple projects are perhaps the most valuable information I could provide.  Fortunately, the subject of process and best practices is something any of us on the IES team could talk about for hours!  Realizing the true scope provided a new challenge: condensing the wide angle view into the time constraints of the presentation.  

The materials research process, whether or not it is for a LBC certifying project, can seem complicated and involved, particularly for the uninitiated. The work does not fit neatly into any spreadsheet, which is why Red2Green, our healthier materials management platform, is so essential to our work. The value of being able to track decisions, communications, research progress and results in real time is incalculable in the process of determining as many approvable products as possible, particularly when we can accomplish this prior to spec writing.

By including clear product specificity in the specs, avoiding general performance language, and only including products that have been vetted and approved for use, we provide clarity to the trade partners and subcontractors to help them feel confident that they are understanding and following the goals of the project. As a follow up step, our “pre-submittal” process provides the confirmation that each product considered at this stage has been vetted and meets the requirements of LBC.

Future Williams College projects, including renovations and routine maintenance, will benefit from the investment in LBC for capital projects, which directly inform the updated college standards and improved specs. Each and every subsequent campus project will have a head start with a greater number of healthy, LBC compliant product options, building upon past efforts to meet the college sustainability and healthy environment goals. Stakeholders at the college can be confident that the lessons learned from LBC certifying capital projects are applied throughout the campus.

The advantages of the Volume Certification agreement that Williams College has pursued and begun to implement seem obvious. With the benefit of data and strategy based on years of experience, the process by which we choose, research, approve and document products that meet the healthy materials goals of the college is involved, but has proven to be achievable, effective and replicable. The truth about striving to use healthier building products in every building project—ultimately the goal of a Volume Certification process—is that we now know how to do it well. And in time, perhaps, it will all sound like common sense.
