Do they still smash a bottle of champagne on the bow of a ship when they launch it? Well, stand back then, because today, Clean Air-Cool Planet launches a new guide called “Energy Efficiency, Renewable Energy, and Historic Preservation: A Guide for Historic District Commissions.” And it took about six months to get it done and get it ship-shape, so it feels like it should be a ship.
And SHPOs are part of the audience – but that’s an inside joke. A SHPO (ship-O) is a state historic preservation office, and that’s one of the types of organizations this report is designed to help, along with historic district commissions and other local organizations and property owners. It’s got 40 pages worth of information on how to make historic buildings more energy efficient, and details ways to employ energy efficiency measures and renewable energy without detracting from the historic value of properties, from private residences to community buildings and museums.
The guide was researched and written by Meghan Giuliano and Virginia Way, two of Clean Air-Cool Planet’s 2009 Climate Fellows, over the course of the summer, when Ginny interned on Nantucket Island and Meg was based at Strawbery Banke Museum for her research on efficiency and preservation.
Ginny’s work, “Sustainable Preservation, An addendum to Building with Nantucket in Mind” was accepted as a formal part of the Historic District Commission guidelines for Nantucket Island, recognized internationally for preservation work. It appears in our Guide as an appendix.
You can download the Guide at www.cleanair-coolplanet.org/for_communities/HDCGuide.pdf.
I had the great pleasure of mentoring Meg and Ginny as they authored the text, as well as a third Climate Fellow, Katie Miller, who was based at the historic site museum Strawbery Banke and worked on implementing energy efficiency strategies and educational programming for the museum. Their work, and my small contribution, has great personal significance to me: I was trained first as an architectural historian and second as an energy auditor. Resources like this are long overdue: Every walk around the 17th-, 18th– and 19th-century streets of Portsmouth, NH, where CA-CP’s headquarters is located, further convinces me that a solution to global warming must include efficiency in every building, and our community can no longer shy away from the challenge of retrofitting historic buildings.
I am thrilled that through Meg, Ginny, and Katie’s hard work, as well as the support of the Roy J. Hunt and 11th Hour Foundations, Clean Air-Cool Planet can share a resource with communities across the Northeast who are anxious to preserve their unique architectural heritage and landscape by making it as efficient and affordable as possible. In so doing, these communities will make a significant contribution to solving global warming since our historic New England neighborhoods were initially planned for energy efficiency.
In this week leading up to the guide’s publication, I sat down with Meg, Ginny, and Katie to talk about energy efficiency, renewable energy, and historic preservation.
Q: So, tell us a little about this guide: Who is it for? How do you hope it will be used?
Meg Giuliano: The guide has several sections, each of which is geared towards a different audience. The first section of the document is intended for Historic District Commissions (HDCs) and preservationists in New England; it introduces some of today’s main issues and players in the energy and efficiency arena. It also suggests ways that Local Energy Committees and HDCs can work together in their communities. The second part of the guide is for homeowners, and it includes a set of frequently asked questions regarding energy efficiency in historic houses.
Personally, I really hope that HDCs and Local Energy Committees all over the region will pick this guide up and read it, and I hope they are inspired to begin work improving the efficiency of their town’s valuable historic resources.
Ginny Way: The use of the Nantucket guidelines as a case study is very important because of Nantucket’s role in the preservation community. Not only do they have an extremely active Commission but also their historic district consists of the entire island. This allowed us to discuss numerous scenarios from strict preservation to new construction. My hope is that all people dealing with historic structures will benefit form this guide. Its advice is flexible enough to fit most situations and it allows a better understanding of both parties. I think any owner of an old building, not just an historic one, can learn form these tips.
Q: Now Meg and Katie, you lived at Strawbery Banke and, in Katie’s case, worked on energy efficiency there. Did walking the walk by living in a 200-year-old building change your perspective on your projects?
Katie Miller: Definitely! Historic buildings are amazing for their character and quirks, but no one really thinks about windows that stick or unusual wiring until you live with it. Dealing with temperature fluctuations was probably the hardest (and most enlightening) part of the experience: I realized how quickly the building could heat up on a hot day, requiring shades to be drawn before leaving in the morning, and how quickly it could cool off in the rain. Being flexible in your layering wardrobe helps, but long-term building improvements such as attic insulation would be necessary for year-round habitability. Living on-site also helped me to see how SBM fit in with its neighborhood, and overall I think it’s doing a great job complementing the area.
M.G.: Well, one of the coolest things about living at Strawbery Banke was learning – first-hand – about techniques and energy strategies employed by early home builders. Many of the buildings at the museum were oriented to the south to take full advantage of the sun’s passive solar energy, and their design suggested a distinct climatic wisdom – the houses were built so that they would be heated and cooled in the right seasons. Early New Englanders also planted trees and other vegetation in strategic ways, so that the houses would be protected from harsh winter winds and shaded in the summer.
Q: Climatic wisdom. I think that’s one of the most interesting topics in the text. Ginny, could you tell us a little bit about how that figured into your Nantucket work?
G.W.: The inherent energy efficiency in historic homes was a large part of the conversation on Nantucket. While most people are aware of the older techniques it was helpful to talk about how those traditional techniques could be integrated with modern ideas. It was also felt, by the historic/green committee, that traditional efficiency techniques needed to be promoted throughout the document. Building owners tend to want the more proactive new technologies instead of utilizing the older techniques; it continues to be a matter of education.
