    This year’s Greenbuild was expected to be in San Diego however it was held virtually, due to the covid-19 pandemic. There were live virtual educations sessions and a virtual expos hall. These covered topics such as electrifying all buildings, embodied carbon in building operations and providing more transparency in construction materials. On-demand sessions will be available for those who need to catch up on continuing education hours for the next 30 days.

    On Day One, there was an informative Opening Keynote from Christiana Figueres and Mahesh Ramanujam. They spoke to attendees through the virtual format about LEED positive buildings by 2050, limiting competition between rating systems and the new USGBC ALL IN equality strategy. Christiana Figueres spoke about how the decade of 2020 will be the most important decade for humanity regarding the environment. She begged the question - do we reach our green goals by 2030? The future is always under construction and humanity must build it appropriately.

    Day Two’s Keynote starred three female designers, Julia Watson, Kotchakorn Voraakhom, and Catherine Huang. These women embrace the concept of a sustainable future using successes from the past. After each designer spoke about their inspirations, they held a round table discussion between the women about what how many new technologies and developments have shifted our symbiosis with nature. 

    To wrap up the conference, at the Leadership Ceremony, awards were given out the project teams and individuals that deserved them the most in an hour-long ceremony that was very well done.

    Overall Greenbuild keeps pushing us to make the planet a greener place for future generations by bringing together the latest education and industry. It is up to the green building professionals around the world to continue a green mission.

    A sustainable building is not only about energy use and occupant health. It's about resiliency. Buildings should be able to withstand what is thrown their way. Here in NH, it's snow. In California, it's earthquakes. On the coast, it's rising sea levels. In 2020, COVID-19 has exposed vulnerabilities and shortcomings.

    As is always the case after disaster, it's time to improve. Fortunately, we know how, and we reached out to Governor Sununu last month to offer advice. There has been no word back yet.

    The first half of this year has been a roller coaster. We started with a bang - a full line-up of tours in the most sustainable buildings in NH, a partnership with Green Advantage, and much more. This all went on hold as our collective focus turned to a pandemic. 

    As we gathered (virtually) to share our experiences this summer, there was a common thread: we miss each other. We miss having shared experiences, seeing great buildings, meeting informally to see where a discussion takes us. Education, jobs, mentorships, and friendships are all taking a huge hit. The best internet connection in the world cannot replace what we are missing.

    With the outside world closed, our chapter has looked to see what else we can offer. We can still video conference with chapter members, as we did for our summer social! We can work with other organizations to provide virtual education opportunities, as you see on our calendar! We can also advocate, as we in our letter to Governor Sununu this year!

    So, keep your head up. Take a look at yourself in that webcam mirror and ask what you can still do. Sign up for that next activity and get out there, even if it is virtually. You are still making a difference, and we would love to hear about it. So, send an e-mail my way if your have something to say.

    Miss you all,

    This year, we celebrated our chapter's 10th anniversary at the new Bank of NH Stage in Concord!

    It is a beautiful venue, and we were happy to announce our event with a proper downtown marquee! We were even more excited to see such an exemplary urban revitalization project by Milestone Engineering. 

    Chapter members and curious passers-by trickled in to network with some food from the Coop and local brews on tap.

    After everyone settled down, we took a couple trips down memory lane. First, I took us back to a couple of our favorite tours from the past year.

    John Pietroniro, our chapter's esteemed chair alumnus and current historian, took us through a history of our chapter. What a trip it has been.

    Then, it was award time!

    This year, we are thrilled to give our "Building of the Year" Award to the William Boyce Thompson Field House. This extraordinary facility not only showcases Philips Exeter Academy's athletic program in quality daylighting (though it does do that quite well). It also halves its impervious surfaces by stacking the track and fields on top of parking. The remaining impervious surface, the roof, is completely covered in solar panels. Peter Reiss, Architect at ARC, spoke to these sustainable features and more, showing our state what we hadn't seen before in a field house. Keep an eye out for a tour this summer!

    To cap off the night, Sam Evans-Brown, host of NHPR's Outside-In, regaled us with Possible Energy Futures. In a whirlwind presentation inspired by experiments around the globe, we had wake-up calls, reality checks, and a call for all hands on deck as we head towards our carbon-neutral goal.

    As I recall this year's 10th anniversary, I also recall the Paris climate accords, which say we have 10 years left to get to carbon neutrality. Never has our mission been more urgent, and never have I been more inspired. It will take everyone: visionaries like Sam, designers like Peter, builders like Milestone, and organizations like Philips Exeter Academy.

    I can't wait to see what you come up with this year,

    The USGBCNH group was having a discussion on ventilation systems recently, and we thought it would be a good topic to share here. 

    Now that winter is almost here and everyone's windows are staying shut for the next 4-6 months, the question about indoor air quality becomes a lot more relevant.  We all know how important mechanical ventilation is for our health and for the health of our buildings, but in the building industry it is still a relatively foreign concept. 

    This is especially true in single family residential design, where the building code is behind where it should be on ventilation requirements.  Homes are now being built pretty air tight thanks to building code improvements, but an air tight home isn't a great solution for the occupant if no fresh air is getting inside. 

    A poorly ventilated home leads to high humidity and mold growth, lack of oxygen, and toxins from materials and household products being trapped in the home.

    So what do we do about it?! 

    I think we are all in agreement that providing balanced ventilation systems is the way to go.  We want to bring fresh air inside the building at the same rate that we exhaust stale air.  But that doesn't go far enough to answer the question.

    There are still plenty of options for providing a balanced ventilation system in a home.  I'm in the process of designing a residential art studio with one main room and a small bathroom, and I had the question, 'What's the best way to ventilate this space?'

    ERVs and HRVs

    We know that using an energy recovery ventilator (ERV) or a heat recovery ventilator (HRV) is a good solution because these units recover heat (and moisture if using an ERV) from the conditioned air to help temper fresh, cold outdoor air before being released in the home.  This helps reduce energy burdens.  

    But now we need to decide if we're using an HRV or an ERV!  In our cold climate, an ERV needs to turn off intermittently so that frost doesn't build up on the unit.  Is this the best approach?  An ERV helps keep some humidity inside the home that our cold, dry winter air doesn't bring in.  Is that benefit worth mitigating the frost issues?  

    Ducted vs Non-Ducted

    And then, as in the case of my small art studio, we need to decide if the fresh air should be ducted through the whole space or if a single distribution system such as the Panasonic WhisperComfort would make more sense.  I asked this question to the group, and it turns out that this type of system doesn't function when it's very cold out.  The Panasonic unit turns off completely when outdoor air dips below 20 degrees F.  

    For a home, a ducted system seems to be the best approach so that fresh air is getting into every bedroom, but is there a method that works well for a large open space (such as a studio apartment over a garage) that doesn't require ducting?

    After some discussion with the energy experts in the group, it looks like the art studio is going to go with a ducted ERV so we can retain some moisture in the winter and distribute fresh air easily throughout the space.  Is this the best method?

    What Would You Do?

    What is your approach for residential mechanical ventilation?  Let us know in the comments below.

    Awards Tour, Part II

    River House, Hanover


    The Architect, USGBC NH Chapter Member Sloane Mayor, led the tour by starting outside. There, we took in the beautiful River and surrounding wetlands, a serene environment demanding protection.

    Unapologetically modern and durable, but modest, materials are used here: galvalume for the standing seam roof, cement fiberboard for the siding. The overall building has been intentionally de-emphasized through simple colors and details, keeping the focus on the beautiful landscape. You may notice one of our members busily tracking the ethereal qualities of the site (light, wind, air quality, I'm sure much more as well - make sure to ask her about it at the next meeting!).

    One of the pieces of testing equipment. This one looks like it's measuring air speed.

    Another piece of testing equipment. I was told, but still do not understand, quite what this does.

     LED "pucks" light up the owner's beautiful artwork and custom furniture. Everything inside seems to be a sustainable product, from the wood to the counters to the paint.

    Yes, the all-important HRV (or ERV?). Crucial in a tight, high-performance house like this to ensure fresh air without a big hit to energy efficiency.

     Even the basement was given special consideration. The finishes and great natural light almost fooled me into thinking we were on the first level.

     With 52 LEED points, and a shared award for last year's most sustainable building, this residence stands out as a success story in NH, making us all think a little harder about how we build our homes. 

    Thanks to both Owner and Architect for the inspiration. I hope many follow suite.

    Today, there are so many green building standards to choose from, including CHIPS, LEED, Passivhaus, Energy Star, Living Building Challenge, … too many to even try to list them all. So, what’s the right standard for your building? Well, that depends on what story you want your building to tell. Let’s take a look at a couple examples.

    • ·         Do you want to cut down on your energy bills? Well, the EPA’s Energy Star and Watersense programs are a great place to start. Get appliances with these labels, and you’re already doing better than most. Check for “Most Efficient” to get the really good stuff. But why stop there?
    • ·         If you want to go really low-energy, then Passivhaus is the way to go. When you get this efficient, you can downsize the equipment you get, and potentially start realizing savings immediately. You can even use Passivhaus as a way to make your building “net-zero ready”.
    • ·         If you add solar panels to that roof, and succeed in producing as much energy as you use, the DOE’s Net Zero, Living Building Institute’s Zero Energy, or LEED’s Net Zero programs would all be great fits for your project.

    Thanks to energy models and accurate data, designers can easily make a compelling economic case for high-performance buildings. Building owners are savvy to this, and are mandating these standards (if not always for environmental stewardship, then at least for their pocketbooks!). For those that remain unconvinced, building codes are requiring more and more efficient buildings as a baseline. In fact, NH’s energy code will be updated next month. This is all encouraging news, and I hope this emboldens designers and building owners alike to create high-performance buildings. 

    So, what’s next? Are we done? No way! LEED consists of 57 possible credits. Most of these have nothing to do with what we’ve talked about so far. In fact, if you remove all the credits that have to do with water and energy efficiency, it’s still possible to get LEED Platinum certification. Don’t believe me? Here’s a theoretical scorecard for you! So, there’s a lot left to explore, and the next step is convincing building owners there’s money in all these other credits. It’s easier than you think!

    For example, let’s focus on the Indoor Environmental Quality credits. You can use daylighting, acoustic isolation, low-emitting materials, indoor air quality, ergonomics, and thermal comfort to boost productivity in measurable ways. All told, you can expect a 16% productivity gain in green workplaces vs. non-green workplaces. As new research about these gains comes to the fore, it becomes easier to quantify these previously “soft” decisions, converting them to “hard” ones. As you business owners know, employee costs increasingly dwarf operating costs. So, expand your focus to include wellness – or be left in the dust.


    See you in the field,

    On Friday, April 5th, our chapter had the unique opportunity to tour the inner workings of the LEED Silver-certified Hillsborough County Superior Court North. John Harper, from Lavallee Brensinger Architects, led the tour. Sarah Lineberry and Steven Lorentzen, from the State of NH, lended us their client perspective.

    Reuse was theme of the day. The entire project takes the best of the old, while updating for contemporary standards.

    A revitalized entrance conveys transparency while maintaining secure sight lines for the public areas. The existing cladding, a beautiful granite, was repurposed as a paving material for a new landscape design.


    The group learns about how to fit all the complex mechanical equipment necessary to run a modern courthouse into an old courthouse. It is not an easy task!


     The group learns about the State of New Hampshire's commitment to the arts, and how this resulted in beautiful hanging installations for the public areas.
