The Indicator: Why the Solar Decathlon Should Enter the Real World

This article, by Guy Horton, originally appeared on ArchDaily as “The Indicator: Why the Solar Decathlon Should Enter the Real World”. 

I don’t mean to poo poo the U.S. Department of Energy’s (DOE) Solar Decathlon project, but the more I hear about it the more I wonder if this isn’t an indication of just how far behind the United States is in terms of energy policy and the design of smart environments. Are we really that far behind that we need a program like this to prove this stuff really works? Are people still disbelieving? Do they really need demonstration homes to show how photovoltaics (PVs) produce electricity or how sustainable principles can be applied to architecture? I suppose it makes sense in a country that still obsesses about the Case Study Houses and has debates about whether climate change is a reality.

The purpose of the Solar Decathlon is primarily to educate the public on high-performance building practices. Since 2002 when the DOE held the first one, it’s been putting “green” building in front of people who otherwise would not get to experience it—or, in reality, a self-selecting population of people who are probably already into such things.

Of course, the other purpose is to get a bunch of architecture students to design and build to gain some practical experience with energy-efficient buildings. The Solar Decathlon has, according to their URL, “Affected the lives of nearly 17,000 collegiate participants.” Undoubtedly, the program serves as a catalyst for young architects-to-be and contributes to the knowledge base of participating architecture programs. How can this be bad?

But does it do anything else? It certainly generates a lot of buzz. But is that buzz that is reaching “tens of millions of people,” as their website claims, having an impact on the mainstream? By setting what are ostensibly mobile homes up in a field, this time in Irvine, California, does it really promote sustainable building practices in a meaningful way?

A little context: I recently returned from a trip to Hamburg, Germany where, even though it can be cloudy a lot of the time, solar power is a fact of life and part of the overall energy picture. People there don’t blink when you bring up PV panels or district solar hot water generation or any number of renewable energy strategies. Solar is simply viewed as part of a comprehensive long-term vision for the city’s energy future. They even believe climate change is real! What a strange land, this Germany.

Now, I think it’s a good thing the DOE is holding these competitions, but I wonder if it wouldn’t be more constructive at this point (this is the sixth event) to get this out of the grassy fields and into the hearts of cities, by partnering with real developers to create real-life affordable multi-family housing, say, in a place where real people need it.

In Hamburg, public-private partnerships were formed to convert existing low-performance housing to smart, high-performance housing. One of Europe’s largest energy companies, Vattenfall, worked with a test group to bring renewable energy (a combination of wind, solar, geothermal, and other sources) to converted flats by employing smart metering and smart grid technology. In fact, they completely re-conceptualized the mode of power distribution/consumption and now envision this new “smart” system as the future of energy use for the city—along with hydrogen buses and electric vehicle infrastructure.

It’s extremely ambitious, and, as an American, I found myself being skeptical. Can they really do this, I wondered. The test group customers have to undergo behavior modification and be re-educated about how to consume less energy and use it more efficiently by following the ebb and flow of renewable power sources. Of course, the smart-grid does much of this for them if they go along with it.

This seems to be the one crucial element of the sustainable equation that often gets overlooked by energy-hungry Americans. People seem to expect that they can consume at the same levels they always have and that houses like Solar Decathlon houses can be experienced the same way they would experience a conventional energy-hog home. It’s set up as if the home has to prove its worth to the customer rather than the customer having to adapt to the home. This establishes a false precedent that, in the long run, undermines sustainable building initiatives.

The other issue is that the Solar Decathlon positions these “experiments” outside the complete context of urban transportation, real neighborhoods, and the overall infrastructure of daily life that would actually “demonstrate” that such homes work.

What if the next Solar Decathlon were in Detroit or New Orleans, or even a Native American reservation out in the middle of nowhere? What if it implicated real energy-users and real buildings? Then it would start to get interesting. Until it does something on this scale it will continue to be temporary, like an event at a World’s Fair or a carnival ride—it will still be something people can question and think of in terms of being outside the norm. The enduring influence of the Case Study Houses, after all, is due to the fact that they are real houses in real contexts, hooked into the grid.

DOE could move beyond the “temporary pavilion” or “demonstration model” approach and actually implement sustainable practices to retrofit existing buildings to have an impact on real communities. This would begin to move their education initiative more into the public realm. By modeling real-world energy initiatives like those found in Hamburg, DOE could increase the real-world relevance of the Solar Decathlon for the future. And if the Decathlon did that, then it could truly consider itself sustainable – in all senses of the word.

I attended the most recent Solar Decathlon and yes, I am part of that self-selecting population of people who is already into such things.

However, listening to the many questions I heard while on house tours, there were many attendees who were asking "basic" questions about solar power and how it works. My four year old, custom built house has 24 solar panels and when I share that information with "regular folks" I meet through my work they still ask such things as where I keep the batteries.

The fact is most folks who buy a home (either previously lived in or new) do not get to make the decisions about how energy-efficient it is, decisions that have been made by prior owners or the developer.

Also my sense is that many home owners, or would be owners, have a wish list of things they want in their home and if you watch HGTV shows you regularly hear that list as folks discuss future purchases or makeovers. Energy efficiency is rarely mentioned, unless the house being made over has displayed annoying symptoms, such as heavy condensation. Intellectually, most folks know energy efficiency can mean payback but it's not as sexy and immediately visible as marble countertops or walk-in closets.

So I agree with notion that the DOE should find ways of targeting developers and offering incentives. The hybrid and all electric car market has experienced various incentives, one being that the average MPG # across the manufacturer's fleet means there will a range of vehicles offered to meet it. And we also have the tax break incentives.

Maybe there should be a similar programs for home developers and home improvement practices.
