One of the many colorful, passionate and gifted people I met while serving on the Greening of the White House National Task Force, in 1993, was John Picard. He's aged a bit in this interview with San Francisco's G-Living TV host Sarah Backhouse, but he is still leading America's corporations down the path of green as the new black. That's black as in profit. Among his clients are Interface, GAP, Sony and now, BP. His message is timely. Why just do green or sustainable when you can go restorative?

Gardening On High
The heirloom tomato seeds have sprouted in the peat pods in our kitchen and soon it will be time to plant them in the garden. Last year I had great success with my side yard plot which was constructed according to the book, Square Foot Gardening, by Mel Bartholomew. You construct raised 4’x4’ beds constructed from 2” x 6” lumber, throw some landscape fabric over the lawn to keep the weeds from growing through, and fill the squares with a special mix of lightweight soils and organic soil amendments (composted kitchen waste is ideal). The soil mix is designed to hold water, cutting down on irrigation requirements.
This experience has led me to speculate that a similar vegetable garden would work very well on a flat roof. If my house had a flat roof, I could have a garden roof with a view that the rabbits wouldn’t eat and I could make a productive, pleasant place to read the paper and sip coffee in my PJs while watching the dewy tomatoes grow at sunrise. I’ll put this on my list of design strategies for my next green dream home (more on that in future articles). The money view from most buildings is from the roof. That's why penthouses are so expensive.
I know what you are thinking. Conventional wisdom says that flat roofs leak and putting wet soil on a roof is insane. Conventional wisdom is a good starting point for design, because it is usually informed by past failures. History has also shown repeatedly, however, that when innovators overcome conventional wisdom with new techniques, civilization makes progress. Let’s look at some unconventional wisdom for a moment.
The technology to plant stuff on the roof is now well proven and growing quickly in popularity across the country, thanks to groups like Green Roofs for Healthy Cities spreading the word about how to do it correctly. An example of the state of the art can be found at Oaklyn Public Library in Evansville, Indiana, which supports an 18-inch deep native mesic (wet) meadow with ponding elements and a subterranean trickle irrigation system for dry spells. That must have been one dimwitted architect!
Uh, as the architect for this project (when I worked for another firm, Veazey Parrot & Shoulders, in Evansville), I can attest we did learn how to put a wet natural meadow on a library roof in 2002 and it is still dry. The meadow extends over much of the seven-acre site in which this earth-sheltered 18,500 square foot building is integrated, such that it is difficult to tell where the building ends and the site begins. In case you were wondering, it cost no more to build this earth-sheltered library. The roof is expensive but three of the walls are just buried cast concrete with no expensive exterior finishes, which allowed it to be constructed for less than the established budget and less than a typical gabled-roof library building. Oaklyn also saves many thousands of taxpayer dollars each year through reduced energy and maintenance costs. For a typical above-ground building, garden roofs do add costs and those costs escalate with the thickness, complexity and amenities. Garden roofs do have paybacks, however, that will eventually recover the initial costs in most cases. Those costs and paybacks vary with each site, garden roof type and building type. The biggest payback is often reclaimed usable space and design schools now refer to the roofscape design as the “fifth facade.”
When approaching new technology, it is important to examine precedents, research best practices and find the best experts. It didn’t take long for us to find the complex garden roof of Chicago City Hall and the designer of its complex garden roof, Charlie Miller, president of Roofscapes, who is one of the world’s premier experts on garden roofs (also known as green roofs or vegetated roofs). Working with Charlie and the rest of the design team, we figured out a way to pull that off. This “particularly robust” national-award-winning garden roof is designed to last for 50-75 years before replacement. It also makes the building more energy efficient, helps with stormwater mitigation, and the earth-sheltered strategy makes good use of an otherwise almost unbuildable hillside site. I would consider a similar, but less complex system for my dream home edible roof garden design. But Oaklyn is a good example of some of the technology available for less ambitious projects. Let’s go through some of the basics.
A growing medium that will support vegetables will need to be at least five inches deep to emulate the Square Foot Garden that occupies my side yard. The weight of five inches of wet soil needs to be added to the normal structural calculations. This would be known in garden roof language as an intensive system, as opposed to an extensive system, which typically are 3 to 4 inches thick and can go where you may already have a gravel ballasted roof. Ford Motor Company has a very large example of an extensive system at their River Rouge Plant. The Indianapolis Museum of Art (by BDMD Architects) has a new parking garage covered by a very intensive system that supports an allee with large trees. Other commercial garden roofs feature pools and fountains or even a full golf course hole. It is a way to reclaim expensive urban space. Chicago is bullish on green roofs because they cool the city and reduce combined sewer overflow issues. They now have 300 garden roofs throughout the city.
Corporate roof golfing!
Many existing buildings, including the building I work in, already have the structural capacity for garden roofs as they were constructed in such a way as to be added to later and the roof was actually designed to be a heavily-loaded industrial floor. Reclaiming such space for use by people, instead of leaving it to the pigeons and the rooftop compressors, has become a hot niche market for many firms.
When you have the structure confirmed, the key decision is what type of membrane to use to keep the elements out of the building. For Oaklyn, the choice came down to two systems; a liquid-applied membrane by American Hydrotech and a heat-welded reinforced PVC sheet membrane system by Sarnafil. Both systems had been proven in very high profile projects around the world and either probably would have worked. Sarnafil allowed for the incorporation of ponding elements (plastic pipe dams heat-welded into a secondary protective cover sheet), which was also heat welded. Oaklyn’s roof system is “robust” in that is has two layers of heat-welded, reinforced PVC membranes, the primary layer and a protective layer. This type of membrane has been used in underwater tunnels and has a thirty-year history in Germany. This membrane is also impervious to root growth, while most organic materials require some type of additional root growth barrier.
To prevent excessive ponding of water that would kill the meadow, Oaklyn’s roof has a slight slope and a subterranean drainage system consisting of low-profile rectangular perforated drain pipe. The overburden of soil protects these premium membranes from ultraviolet light, extreme temperatures and physical damage. Welds are tested prior to adding soil mix by flooding the roof for 24 hours. Another advantage of a heat-welded sheet membrane is that the same system can be used to flash penetrations, parapet walls, and other interruptions where leaks are most likely to occur in any roof system. Sarnafil also has certified installers, which means you get experienced crews who know what they are doing. It is also a good idea to compartmentalize sections of the roof and embed electronic leak detection so that any eventual problems can be discovered before any damage is done and repairs can be made without removing large sections of overburden. Consider this cheap insurance.
Garden roof technology continues to improve rapidly, with new developments like pre-planted trays for rapid starting of the living part of the system. Live Roof seems to be leading this trend.
Sixteen species made up the initial meadow planting at Oaklyn Library
Oaklyn used plugs of living meadow plants in 16 species. The key consideration for roof gardens is whether they will be accessible and frequently maintained, like a vegetable roof garden, or if they will have to fend for themselves without much maintenance and without irrigation. In the latter category are plantings of sedums and mosses that can survive extreme conditions normally seen on rooftops without irrigation.
Getting back to a garden on your home roof; some of the advantages, other than more usable outdoor space, include: increased energy efficiency, sound isolation, disaster resistance (fire, hail, high winds), significantly longer roof life, less stormwater runoff and a supply of very fresh food. Aesthetically speaking, this will work best when the building is already designed in an architectural style that features a low-slope roof. My guess is your subdivision's covenant would prevent you from lopping off your massive neo-French hyper-hip roof that matches those of all your neighbors. This would be great in an urban setting, however, when you don't have much of a yard or garden space on the ground plane or on a contemporary-style custom home. For a design from scratch, you would have the option of raising the garden to the roof, or, if you have a nice south-facing slope with a view, put the house under the garden. Since you have all that new flat landscape, you may also want to put some solar hot water panels and solar photovoltaic panels up there to wipe out your electric bill and charge your electric car. More on that later as we continue to explore the green dream home.

Eleven-foot tall windows help daylight earth-sheltered Oaklyn Library.
Oaklyn Library used a composite concrete deck (where the poured concrete locks into a specially-designed corrugated metal deck and both are strengthened) to support a very deep garden roof. A concrete deck would probably not be necessary on a residential garden roof, but it may be a good choice if you are using cast concrete walls, which would be a great way to go on a home for other reasons (more on this in a future article). Larry Crane at Crane Builders uses this type of system to build floors in his multi-level insulated concrete form (ICF) walled homes. With typical wood-framed construction, garden roof capacity could be achieved with deeper joists, parallel chord trusses or engineered wood microlam or glulam beams or with I-joists. On existing homes, it would probably mean sister joists, but be sure to check with a licensed architect or structural engineer before doing anything on your own. There are other considerations, like lateral loads in earthquakes, to consider, depending on your location and loading capacity of your walls and foundation.

Dynamic Virtual Design
A well-designed and constructed building should last for a century or longer. Design decisions last for generations, but they are often made with little more than guesswork. Experienced architects eventually learn from their mistakes, but those mistakes tend to outlast the architect. A better approach is to model the building in detail during early design and tweak the design to optimize the building's performance. When you optimize a design, you make it work better for less money - for a very, very long time.

With the advent of sophisticated computer modelling software, it is possible to get an accurate idea of how a building design will perform long before the building is constructed. A good suite of modelling software can tell you:
- How much ambient light will be provided by natural daylight on December 21 on a cloudy day?
- What is the effect of adding wall or attic insulation on the size of the heating and cooling system?
- How many photovoltaic panels will I need to balance the energy needs of this building on an annual basis? What if I changed from fluorescent to LED lighting?
- What size of clerestory windows will allow the best natural ventilation and will all parts of the building be adequately ventilated?
- Will the building next door shade the solar panels on my building?
- If I put a white roof on this building instead of a black roof, how does that effect my heat gain and heat loss for the year? What if I put on a vegetated roof?
- How much energy will this building use and what will it's carbon footprint be?
Many architects today still use pencil and paper and build physical models (if any), but a growing number are moving to 3D software that allows a design to be "built" in the computer before it is built in the real world. One 3D modelling software program that anyone can learn to use is SketchUp, which provides some rudimentary evaluation tools, such as simple shading analysis. There are also add-ons to export these simple models as green building extensible markup language (gbXML) files which can then provide the basis for detailed energy and building performance analysis with energy, ventilation and daylight modelling software.

To get more accurate modelling data, however, sophisticated building information modelling (BIM) programs like AutoDesk's Revit Architecture are typically used. This software helps architects visualize the design but it also can help determine how well its systems will function. When the whole design team utilizes these tools during early design, little effort is wasted on guesswork. The computer model removes the guesswork and informs a more dynamic and accurate design process, which leads toward a more successful end.
I've been impressed with a relatively inexpensive analysis tool called ECOTECT from Square One Research, which generated the images in this post. Another interesting analysis tool is Green Building Studio, which is about to be acquired by Autodesk, which means it will probably cease to be free. GBS can do a whole building energy analysis of your model when you export it and upload it in gbXML format. GBS can also export to popular engineering energy analysis tools like DOE-2, eQuest, EnergyPlus and Trane Trace700, which can provide energy performance data for any hour of the day any day of the year.
We are finally entering a time when architecture is no longer just a fashion show. We want our buildings to look great and we want the experience of the architecture to be elevating, but we also want them to PERFORM! Green buildings perform by delivering delightful, healthful, daylit, comfortable spaces that are energy and resource productive. The best way to get there is by means of a dynamic collaborative design process assisted by state-of-the-art design tools that can tell us how well the building will perform before the shovels hit the ground and before you open your first utility bill.

In Defense of Michael Pollan
When my wife and I saw that author Michael Pollan would be speaking at Butler University near our home, we immediately marked it on our calendar. He has had my attention since The Botany of Desire (2001 Random House), but his The Omnivore’s Dilemma (2006, Penguin Press) began to change our eating habits. We just finished his latest book, In Defense of Food (2008 Penguin Press), and that was the basis for most of his talk this past week. We weren’t the only ones in Indianapolis who are apparently avid Pollan readers. Atherton Hall was filled a half hour before his talk and university officials quickly opened another lecture hall linked via closed circuit broadcast.
Pollan began his lecture with the words that opened his latest book, with the advice to “Eat food. Not too much. Mostly plants.” Then he developed his convincing case for that recommendation. He described the irony that we live in a country where millions of people are suffering from obesity and malnutrition at the same time. Food-related diseases like Type II diabetes and obesity have become so common as to create new “lifestyles” with their own magazines and supportive industries. These “Western Diet” diseases have similar effects in other countries as the impoverished increase their incomes to the point where they can afford to consume American-style processed food. Wherever our food goes, so goes our lethal food-related diseases.
"Eat food." The test for this is to eat only that which your grandmother would recognize as food. That would probably not include spray imitation “cheese” in a can, for example. The shorter the ingredient list the better. One unprocessed ingredient is ideal. Much of what we eat is so highly processed that most of the nutritional value is missing and we are left with little more than the calories and chemicals. Pollan recommends staying out of the center of the store and sticking to the whole foods on the outside of the store. The best food has no health claims or even labels. Think vegetables and fruits and other real whole foods. Better yet, get your food from the local farmer’s market or your own garden. Yes, that means you may need to relearn how to raise a garden and cook, but the rewards of unadulterated fresh food are worth the effort.
"Not too much." This is pretty obvious, but he notes that we eat more than our healthier counterparts in other countries, such as Italy, where eating is a slow, social process with smaller servings that are more mindfully consumed over a much longer period of time. In our fast food nation we tend to eat so much so fast that we overshoot our signals of satiation and miss a lot of food appreciation along the way, not the mention the loss of the family sit-down meal. Pollan cited an unbelievable statistic that 20% of American meals are consumed in cars.
"Mostly plants." Numerous studies, notably The China Study, by Collin Campbell, have shown that consuming a diet that includes a significant portion of animal products, especially red meat, can lead to health problems ranging from heart disease to cancer to premature puberty in girls. In those populations where the diet is all or mostly plants, these diseases are virtually nonexistent and people enjoy longer, healthier lives. Pollan recommends consuming free range or wild animal protein, if any, to avoid the health problems associated with meat produced in confined industrial farm operations with unnatural diets that require massive doses of antibiotics augmented with growth hormones.
The bonus of an organic, local, plant-based whole food diet, other than better eating and personal health and longevity, is significantly reduced environmental impact. A 408-page report by U.N scientists, Livestock’s Long Shadow, indicated that raising animals for food is responsible for more greenhouse gases than all vehicles in the world combined. More than 260 million acres of U.S. forest have been cleared to create cropland to grow grain to feed farmed animals; farmed animals are fed more than 70 percent of the corn, wheat, and other grains grown in the U.S.; and almost half of the water and 80 percent of the agricultural land in the U.S. are used to raise animals for food.
So what is it like to really veg out? We have been learning to prepare whole plant foods from our garden, from the local farmers’ markets, from our local whole foods stores (and the mainstream stores increasing their whole foods selections) and from our local farm delivery service for the past six months and it has been a journey from the artificial and the bland to the real and the delicious. We have learned how to cook again and we have learned to appreciate our food and our experience of food more. We can enthusiastically report that it has been a very pleasant adventure in better foraging, tastier food and a more relaxing dining experience. The fact that we have also significantly reduced our carbon footprint is a huge bonus.
It was no surprise that we had trouble finding a seat at Butler’s Atherton Hall to hear Michael Pollan and it is no surprise that In Defense of Food is #2 on the New York Times Bestseller List.

Investing in Energy Productivity
When I look at the rapid fundamental transformation needed in energy policy to achieve IPCC recommendations for stabilizing greenhouse gas emissions and then look for evidence of these changes taking place, it is hard to be optimistic. It seems we are shoveling coal faster and faster on a runaway train when we know there is a bridge out around the bend.
So it was with some sense of hope that I read the new report by McKinsey & Company, The Case for Investing in Energy Productivity.
This report offers a new a way to frame the policy debate by offering strategies to make money while also significanty reducing greenhouse gas emissions. The authors have also offered a new phrase, "energy productivity," which causes a reframing of the old energy efficiency or conservation paradigms. Much like refocusing one's eye while looking at a Magic Eye picture, this opens up a whole new vista of opportunities to bring divergent causes together for the common good.
Can we invest our way to a more stable climate? If so, everybody wins. Let's get started!

Signs of the Greening of Indiana
In a few weeks, a walk in a Hoosier woodland will reveal the first signs of Spring as new green growth pushes up through the brown detritis of seasons past.
Can Indiana's economy perform the same miracle of new life, pushing new cleantech industries up through the rotting asphalt of boarded up factories? This miracle has already occured in similar rustbelt states like Pennsylvania, but can it happen here in the state Forbes ranked 49th among "America's Greenest States?"
Let's explore a few of the first signs of the Greening of Indiana.
Indiana Wind
When you look at a wind map of Indiana, you see at least six counties with marketable wind resources. What you will also see on that map are transmission lines that interconnect several states and major metropolitan areas. We have the resource, the means of transport, and the nearby markets. That is why we also have several wind companies designing and installing million-dollar wind turbines in our corn fields, employing Indiana contractors, and paying leases to Indiana farmers. By this summer, 200 megawatts of wind will be online with a total of 2000 megawatts in some stage of planning in Indiana. New wind is already cheaper than new coal, according to eye-opening presentations by Larry Flowers of Wind Powering America and Jeff Anthony of American Wind Energy Association. If you have made a trip along I-65 lately, you have probably seen some of the gigantic components in transit. Some of those components are coming from overseas, but they could be made right here. World demand for wind turbines is such that it takes 18 months to get an order filled, if you have the connections. Manufacturing capacity cannot keep up with demand. This is potentially a huge part of Indiana's future economy, both as a supply of clean, inexpensive, pollution-free, renewable energy and as a manufacturing opportunity, not to mention a boon to farmers who can lease their land for wind and still farm it. The Indiana Wind Working Group is planning a two-day symposium, June 17th and 18th, 2008, at the Indianapolis Convention Center, to help make the connection between manufacturing opportunity and capacity.
The Legislature could greatly accelerate that process and create hundreds of new jobs by doing what 24 other states have already done, enact a renewable portfolio standard (RPS) that requires our utilities to get a percentage of their power from renewable resources. That should be an urgent issue for all legislators concerned about the health of taxpayers, the health of our economy, our energy security, our competitiveness and the full employment of our workforce. It's time to diversify our energy portfolio. A bill in the House to do that, HB 1102, was one vote short of a constitutional majority to pass out of the House.
Green Buildings
At the beginning of 2007, there were ten Indiana projects registered for the LEED Green Building Rating System (out of 8500 in the rest of the land) and there were 80 Indiana Chapter members. By the end of the year there were 86 registered projects and 220 members in Indiana. Many of those members traveled to the Greenbuild International Conference in Chicago in November, where attendence was more than double the previous year's record number of 13,000 in Denver. We are still behind our neighboring states, but gaining. Over $2 billion in building projects in Indiana are currently in some phase of design or construction using LEED as a benchmark. House Bill 1280, Energy Efficient Buildings, passed out of the House and moved on to the Senate for consideration, where it was amended to a summer study committee. That bill called for public projects in Indiana to be designed to LEED or equal green building standard, which would save taxpayers millions of dollars in energy, health and productivity savings, improve the health of building users and the environment, while also creating new jobs. Ball State University, Indiana University, Purdue University, Butler University, University of Evansville and other institutions of higher learning in Indiana are leading the way with LEED projects in progress. The Merry Lea Environmental Learning Center at Goshen College has been certified and it is the first LEED Platinum level project in Indiana.
The following Indiana College and University presidents have signed on to the American College & University Presidents Climate Commitment: Ball State University - Jo Ann M. Gora, President (a member of the Leadership Circle); Franklin College - James G. Moseley, President, Goshen College - James E. Brenneman, President; Indiana State University - Lloyd W. Benjamin III, President; Rose-Hulman Institute of Technology - Gerald S. Jakubowski, President. That's leading by example and practicing what you teach!
Indiana Renewable Energy Association
This new industry web site and blog posts impressive blow-by-blow accounts of key Indiana renewable energy legislation and they have excellent explanations of complex topics like netmetering and renewable energy standards. If you provide a level playing field with legislation you open the floodgates to investment from the world-wide renewable energy industry. If not, many of these investors will look elsewhere first, like #32 Pennsylvania. Go to this web site to see how your legislators voted on these issues and let them know your opinion.
INdiana Sustainability Alliance
Founded by a couple of young Ice Miller LLP attorneys, Alex Forman and Paul Jones, the INdiana Sustainability Alliance was created to, "bring together business leaders, policy makers, investors, entrepreneurs, educators, developers, scientists and other professionals in the fields of sustainable development, green building, renewable energy, water management, and clean technology."
