Let’s talk about zero energy architecture and the Truro Residence. It’s an amazing residence, currently under construction on one of Cape Cod’s beaches in Massachusetts. Designed by Independence Energy Homes (IEH) and being constructed by Silvia and Silvia, the Truro Residence is meant to accommodate a large family and friends and still remain environmentally responsible. When complete, it will have a tight building envelope, a geothermal heating system, solar photovoltaic system, tank-less water heaters, compact fluorescent lighting, and Energy Star appliances. The home also will feature popular green materials such as bamboo flooring, blue-jean insulation, and natural stone.
Pretty much everyone is talking about green roofs these days, so I thought I would round up a few of the good articles. Just as a refresher, back in March, I wrote an article summarizing the costs and benefits of green roofing. The benefits are numerous in comparison to the costs, but a green roof may not be right for every application. I'll let you decide, but to get you thinking, here are some of the most thorough articles on green roofing that I've read and studied. There's also some eye candy with each, too.
- Green Roofs + 13 pages of pictures, Andrea Ford.
- Green Roofs: An Introduction with Pretty Pictures, Philip Proefrock
- Green Roofs: For Healthy Australian Cities
- Green Roofs: A Primer, Lloyd Alter
- Green Roofs, Jill Fehrenbacher
- Sod Roof Doghouse, Kitty Bartholomew

I watched this video of the Jellyfish House by architects Lisa Iwamoto and Craig Scott, and needless to say, I was kind of blown away. It’s quite compelling to watch, but at the same level, it’s complicated. I can’t say I understand everything that’s going on but I like it. Jellyfish are responsive to the environment around them, so like jellyfish, one concept with this house is that water is filtered and harvested through the actual structure of the home. The structure uses UV light filtration, which could come down in price in the future, and titanium dioxide, which is now used for self-cleaning glass in tall skyscrapers. This concept prototype for the future of sustainable living was designed (hypothetically) for Treasure Island, a decommissioned military base in San Francisco Bay with toxic top soil.
This green home was built in 2003, so it’s not anything new in particular, but I wanted to share some of the green concepts the homeowners worked through during process of building it. First, the owners, Brandy LeMae + Joseph Vigil, purchased an odd-shaped lot near a well-traveled road for $157k. It was rather cheap, with some lots in Boulder costing nearly $400k, so the design would have to solve the noise and space problem. Second, they wanted a green home on a budget. In the end, they were able to build the Hickory House for about $91 psf. There’s an excellent article from Dwell about their process, but I’m going to explain a little below.
The owners raved about structural insulated panels, or SIPs, which went up quickly, were cut to size, allowed for minimal waste, and helped to defray the costs of the project. They also used Forbo natural linoleum countertops, radiant heating in the concrete floors, and denim by-product cotton insulation. LeMae + Vigil tried to keep the design simple — the more complicated the design is, the less money there is to go towards green things (check out VaST’s 3 Design Strategies to Build Green + Save Money). Vigil also designed a foot-wide concrete-block wall stuffed with foam insulation for the west side of the house. By doing this, he was able to block out noise from the road and provide shading for the home. They finished up with some interior design straight from IKEA and were happy with the final product. Looks great from this angle. More images below.
The implications of this research are unbelievable. Seriously. I’ve written about the ten common problems associated with sprawl previously, but this story opens up the discussion again. Angkor Wat is the home of a magnificent temple in Cambodia and was the center to one of the largest cities in the pre-industrialized world. Recently, NASA used ground-sensing radar to study the extent of the city and found that it took up approximately 400 square miles. In comparison, Phoenix sprawls across about 500 square miles, not including the suburbs. The research revealed a complex network of canals, 1,000 man-made ponds, and roughly 70 long-lost temples. The canals carried and distributed water towards the temple and through the south of Angkor. Interestingly, the study also revealed evidence of breaches in dykes and areas where they attempted to fix the canals.
What’s most interesting is the idea that Angkor’s increasingly intricate and complex system of canals might have been too expensive and difficult to maintain. So, there was an elaborate infrastructure that might have run into disrepair … which possibly contributed to the downfall of Angkor? This is very interesting research. Apply that to our situation and query whether the issues we have with the levees in New Orleans or the bridge in Minnesota parallel the situation in Angkor. Do we have an infrastructure, fueled by sprawl and fractional planning, that is too expensive to maintain?
There's an excellent interview by CNN with Ken Yeang, principle of the UK firm Llweleyn Davis Yeang. Almost a year ago, I wrote about Yeang's fascinating Menara Mesiniaga building, and that article has been a popular one in terms of visitors. Yeang is an ecological, architectural visionary designing in a way that blurs the boundary between the natural and human-built environments. With eco-logical design, the goal is to build a structure with no pollution or waste. And we're getting there, too. To quote Yeang, "we'll see green buildings long before 2020 — I think the movement is intensifying. Within the next 5-10 years we'll see a lot more green buildings being built. Not just buildings but green cities, green environment, green master plans, green products, green lifestyles, green transportation. I'm very optimistic." The green buildings pictured in this post are only a fraction of those designed by Ken Yeang.
