Buffalo House to Weather Rainstorms in Kansas

U of Kansas grad students have just completed their chic Buffalo House at Springfield in Kansas City, designed with a very elegant approach to sustainability.

We are seeing more climate conscious design in architecture: In this case; the rain screen.

A skin over the house is designed to manage and harvest occasional heavy precipitation, to provide protection from premature decay from moisture intrusion.

I like the way the rain-screen is carried up over the roof and mounted flush with the photovoltaic solar panels on the roof for a sleek look while also protecting the building.


Like a skin over the building; this Cumuru wood cladding is designed to shed rain water separately from the structure of the building. Rain screens deter rainwater intrusion into walls – by shedding most of the rain and by incorporating storage to reuse the rainwater – which you can see below the doors here.


There’s 8 other sustainable features, as well.

Rather than attacking the symptoms of moisture intrusion, rain screens tackle the source-the forces that drive water into the building shell. By neutralizing these forces, rain screens can withstand extreme environments. They appear to be effective in any climate and handle any weather condition short of a disaster.

All rain screens include the following elements:

  • Vented or porous exterior cladding
  • Air cavity (a few inches of depth is sufficient)
  • Drainage layer on support wall
  • Rigid, water-resistant, airtight, support wall

Integral gutters and downspouts are hidden behind the rain-screen. These then carry rainwater for storage in underground tanks.

The home also features passive solar heating through large expanses of south facing glass. These windows are protected from the summer sun with fixed sun louvers made of steel and Cumaru wood.

So as not to trap too much heat, low South-facing operable windows work in tandem with skylight vents in the north-facing roof-top pull hot air out of the top of the building for a thermal chimney effect.


For maximizing filtered daylighting, a three-level steel frame with milky glass inside encloses the staircase for spatial separation but spreading daylight between the rooms of the house.

The sustainable features are:

1. Enough rooftop photovoltaic solar panels for a net zero electricity supply (90-100%) for an average home.
2. One on-site 1.2 KW Windspire wind turbine that could produce about 20% of the energy an average home (550 kWh a month) assuming wind speed of at least 12 miles-per-hour year round.
3. Geothermal heat exchange between the house and the below-ground 55 degree temperatures year round, providing a constant starting point for both heating and cooling.
4. Epoxy coated gyp-crete floors for interior thermal mass to prolong passive heating and cooling
5. Passive solar design: low South-facing windows with sunlight access to thermal mass in the floor.
6. Heat-chimney effect created with roof ventilation in North skylights for expelling hot air
7. The framing wood was recycled from an ammunition plant.
8. Recycled materials in interior finishes such as the composite recycled paper countertops.

and of course

9. The rainwater reclamation using a wooden slat skin to keep water off the building and stored in underground tanks. Cumaru is one of the hardest woods on the planet and can be harvested sustainably.

But it comes from South America, so there is quite a carbon footprint getting it to Kansas City.

It’s the TSA’s 10th birthday. Should we celebrate?

The Washington Post November 13, 2011 | Christopher Elliott Happy birthday, TSA.

The federal agency charged with protecting the nation’s transportation systems turns 10 Nov. 19. And although its supporters will probably spend the coming days talking about its apparent successes, including the absence of a 9/11 sequel, the question of whether we’re better off with this fledgling $8 billion-a-year federal agency remains very much unanswered.

Maybe it’s a good time to ask it. Not only has the Transportation Security Administration been with us for a decade, but it’s also the one-year anniversary of the unpopular pat-down rule, when officials arbitrarily decided to either send air travelers through the agency’s new body scanners or frisk them. A citizen-initiated petition on the White House Web site encouraging the government to eliminate the agency is gaining momentum, having collected more than 30,000 signatures.

So what are the TSA’s major achievements? Greg Soule, an agency spokesman, offers a list that includes the TSA’s quick formation after the Sept. 11, 2001, attacks and the fact that no major terrorist incidents have happened on its watch. “Through significant improvements to our processes and technologies, as well as the ongoing professionalization of our workforce, transportation systems are safer now than they ever have been,” he says.

Several experts who have been supportive of TSA policies in the past agree that the agency has done a respectable job during its first decade.

“The TSA’s greatest accomplishment is treating transportation security like the serious, professional, your-life-depends-on-it law enforcement job that it is,” says Mary Schiavo, a former inspector general with the Transportation Department and now a lawyer in Mount Pleasant, S.C.

She says that air travelers have forgotten pre-9/11 airport security, which was run by the airlines and was porous and shoddy. Do we really want to return to that? “The airlines allowed 9/11 to happen,” Schiavo says. “They caught [9/11 hijacker] Mohamed Atta at Boston Logan Airport on May 11, 2001, knew he was photographing, filming and watching the security checkpoints at the airport, and they let him go.” Frank Cilluffo, director of the Homeland Security Policy Institute at George Washington University, believes that the TSA deserves recognition for adapting to meet the terrorist threat since its creation in 2001. When it comes to aviation security, he says, there’s no quick and easy fix, and the agency’s approach of building a layered defense and using intelligence underpinned by technology and a well-trained workforce is keeping air travel safe. go to site boston logan airport

But other TSA watchers aren’t so quick to label the agency a success. Steve Lord, the director of homeland security and justice issues with the Government Accountability Office, considers the TSA a “work in progress.” It has made significant improvements in some areas but is “still trying to meet other key goals, such as meeting the congressional mandate to screen inbound air cargo,” he says. “Also, they need to adopt more risk-based screening measures to deploy resources more effectively. A one-size-fits-all approach is inefficient and tends to frustrate the traveling public.” Some experts are more critical. Rich Roth, the executive director of CTI Consulting, a Germantown firm that specializes in aviation security, says that the TSA has been “a miserable failure” at one of its unstated goals from the beginning: making travelers feel that they’re more secure than they were under the private screeners that the agency replaced.

Clark Ervin, who was the Department of Homeland Security’s first inspector general and now directs the Aspen Institute Homeland Security Program, considers the TSA’s biggest shortcoming to be its slowness in adopting cutting-edge technology to make air travel safer. “Generally, such technology is deployed after security threats have materialized and not beforehand,” he says. site boston logan airport

But when the discussion moves from the theoretical to the practical – that is, when I talk to air travelers about the TSA and its achievements – the responses are a little less diplomatic.

Although many passengers are grateful to the agency for protecting them and are generally supportive of its efforts, the federal screeners have no shortage of vocal detractors. Sommer Gentry, a math professor from Annapolis and an outspoken agency critic, believes that in the past decade, the TSA has made air travel miserable. She sees the agency’s legacy as one of rude employees, nonsensical rules and violating passengers’ privacy.

“Over 10 years, the TSA’s demands have become more and more offensive to a normal person’s sensibilities,” Gentry says. “After each new outrage, the TSA simply refused to acknowledge legitimate criticism, refused to subject its procedures to any cost-benefit analysis, and somehow travelers seemed to resign themselves to more and more debasement.” Frequent agency critic Bruce Schneier agrees that passengers have simply rolled over. The TSA, he claims, “has turned airplane passengers into sheep.” And so, as the TSA marks its anniversary with what I’m told will be a brief reflection on its accomplishments, what’s the answer to the question of whether it’s worth keeping?

I’m terribly biased. I’ve been covering the agency since the beginning, and we haven’t always gotten along. The agency has on various occasions lied to me, threatened me and even served me with an illegal subpoena in an effort to persuade me to reveal the name of a source. (I declined.) If anyone has a reason for wishing that this agency would go away, it would probably be me. And yet I’m not entirely convinced that eliminating the TSA would be the smartest move.

I’m deeply skeptical of the agency’s suggestion that it has somehow prevented another act of terrorism. And although the TSA has never been anything less than professional when I’ve flown, I agree with the detractors who say that it seems to operate above the law and with virtually no accountability to the taxpayers who fund it.

All that’s certain is that we haven’t had another 9/11 in the past decade. Would that also have been true without the TSA? Possibly.

Perhaps the only thing I can say for sure is this: We should never stop asking ourselves whether we’re better off with the TSA.

After all, we’re not all sheep.

    Cumuru wood “can be harvested sustainably”–was it actually?

    It seems like this is a greta time to go solar with all the rebates and incentives. There is a 30% energy tax credit from the IRS. A lot of states have rebate programs that can cut the cost of solar by another 30% or more. So depending on where you live, you’d save about 60% off. I found a good site that has the rebates for every state at http://freecleansolar.com

  11. The house does use a geothermal heat pump and the square footage is only 2500 … I don’t know where you got your numbers, but I was one of the students to build the house. The cumaru siding is also fsc certified so it was harvested sustainably and yes it can be hard to justify its shipping from brazil to kansas city but it is nearly impossible to find a hardwood in america that is as durable. All materials in the home were chosen for their sustainable aspects, longevity and ease of upkeep for the home owner. Cumaru is one of the few woods that we felt could deal with kansas’ harsh weather with minimal protection (i.e. sealers, paint and the such which would require reapplication by the homeowner which we wanted to avoid).

  1. [...] Well, no. The McMansion-sized size of the thing at  4,280-sq.-ft is not so planet friendly; because it takes more energy to heat and cool a larger space. But this house would be well suited for a ground heat exchange to passively heat and cool itself with 55 degree air cooled from 10  feet under the ground. [...]
