The Lowest Utility Bill on the Block

Hybridization is hit or miss (i.e., the jackalope). But this Houston home combines two housing types to create a conscientious alternative.

Even before the words begin to form sentences, when you talk to Brett Zamore about Houston and architecture you understand it’s going to be an intense conversation. He speaks with the kind of fervor normally reserved for topics like politics, the reason for which soon becomes clear: According to Zamore, Houston’s politics are dom-inated by huge developers operating in a new kind of sprawling, zoning-restriction-free Wild West. As the conversation continues, you cast Zamore in the role of Wyatt Earp—he’s quietly taking a stand.

“You’ll be in a neighborhood and it can change in a blink of an eye,” Zamore says somewhat excitedly. “Over the past ten years the city has been devoured.” A decade ago, Zamore was a graduate student at Rice University, where instead of playing mind games with paper architecture, he renovated a shotgun house in Houston’s Fifth Ward district, giving the house and the neighborhood a much-needed face-lift.

At the time, David Kaplan, now a business reporter for the Houston Chronicle, befriended Zamore while writing about the project for a Rice publication. A few years later, Kaplan was ready to find a place of his own. Instead of settling for one of the thousands of developer homes that have altered the Houston landscape like a non­indigenous parasite, Kaplan, still fond of the shotgun, rang up Zamore. The pair looked at possible fixer-uppers in Eastwood, an old residential and industrial neighborhood close to downtown that had yet to be clear-cut by developers. Zamore soon had a different idea: to build something from the ground up.

For the young designer, this didn’t mean dreaming in computer-molded blobs and subjecting the neighbors to a vision of Houston 2040; rather, Zamore conjured the area’s architectural past. Unlike the Wal-Mart mentality of developers (who’ll sell the same thing from Minnesota to Mississippi, regardless of practicality), Zamore based his design on a fusion of the hot and humid South’s most successful housing types: the shotgun and the dogtrot.

Sitting on two long and narrow lots, the Shot-Trot, as it is now known, borrows its 16-by-80-foot footprint from  the shotgun. At the building’s center two large barn doors slide open on rails, creating a central breezeway—like a dogtrot. This was a pertinent exercise in historical reenactment. “Old homes were designed to have air flow through them and cool themselves off as best as possible,” Zamore states. “It’s like a self-mechanized air-conditioning unit.”

Like its neighbors, the Shot-Trot sits 30 inches off the ground on a framework of beams and drilled piers, which, according to Zamore, is both “critical for the success of air movement in the house” and better protects the home from floods and their aftereffect, mold (both of which plagued the city after Tropical Storm Allison in 2001). The Hardiplank exterior clad-ding was accordingly chosen for its resistance to humidity and termites. As a further measure, the walls of the house are designed to allow airflow from the base to the eaves by maintaining a gap between insulation materials.

By envisioning the Shot-Trot as a kit of parts, Zamore was able to scale back on construction costs and minimize waste of time and materials. He based the house on an eight-foot grid that accommodates standard-sized wood members, such as the four-by-eight sheets of plywood used in the decking throughout. Installation for these and much of the framing required little more than a nail gun, eliminating cumbersome onsite cutting. Materials were further consolidated, and precious time saved, by using prefabricated elements from local sources. Wooden trusses for the roof were constructed offsite by All Pan Inc., and installed in less than a day. The Galvalume roof, chosen over asphalt tiles for its longevity and ability to deflect heat, was ordered to size, and set in place shortly thereafter. One of the home’s most luxurious elements, old-growth pine and red oak flooring, was salvaged from local tear-downs. (While demolished homes are common in Houston, according to Zamore, salvaging, unfortunately, is not.) In the end, the Shot-Trot modestly priced out to slightly less than $100 per square foot.

While Zamore is further developing the kit of parts into a full-fledged prefabricated Shot-Trot, Kaplan and his dog Bella are happily moved in, and are enjoying a home that befits the neighborhood and has the lowest utility bills on the block, if not the city.

Worth the Wait -Tiny Off-Grid Cabin in Maine is Completely Self-Sustaining

On an island 20 miles off the coast of Maine, a writer, with the help of his daughter, built not only a room but an entire green getaway of his own.

A project 30 years in the making, this tiny off-grid retreat on a coastal island in Maine is almost entirely self-sufficient. Designed and built by Alex Porter for her father, the project features a shed roof and is wrapped in a distinctive blue-grey corrugated skin. Dwell recently profiled the home, which is the only solar-powered retreat on the isolated island – its sustainable power source actually makes life a lot more leisurely, as the family does not need to schlep in fuel to run a noisy generator. They didn’t give anything up, as they have all the conveniences of a regular home — but with a view you don’t get in an everyday residence.

The house is situated on an tiny sleeve of rock tucked close to the water. The sturdy steel cladding was chosen for a good reason — the northern squall can be relentless. The cabin has a series of rolling storm panels that close it against the elements. When the sun shines, a small solar-electric panel mounted to the southern facing roof feeds 12v DC to the batteries, which in turn power lights, a super efficient Sunfrost Refrigerator, and a small water pump. A large rainwater catchment tank provides more than enough water for the home, and a small on-demand water heater supplies an outdoor shower and the sink.

Given the remote location of the property the site’s lack of power, the design made careful use of all materials so that everything is spaced on 24-inch centers. Much of the finishing materials were sourced locally and floated in. One big question remains — what to do when you need to use the loo? A Sun-Mar composting toilet does the job, transforming the waste to into fertilizer. While none of the systems are ground-breaking, the design is a transparent example of how well off-grid living can work, and how we can live in nature without polluting it.

Straw Bale Eco Center / Students of Ball State University Department of Architecture


Located on an 80 acre field station on the prairie of  the Straw Bale Eco Centerwas a community project between Ball State University Department of Architecture students, professors, building professionals, elementary school students and the general public. The classroom and ecology center was a project of complete collaboration, resulting in immersion learning, education outreach and research initiatives, it is the first carbon neutral load bearing straw bale public building in the region.


The Straw Bale Eco Center was awarded the 2008 Merit Award for Excellence in Architectural Design by , 2008 Alternative Power and Energy Award, 2008 Accent on Architecture Award, and 2007 Green Building Initiative Award.

One of the great challenges facing the next generation of architects is to understand and embrace the principals of sustainable practices while at the same time applying these principals in creative ways, embracing their potential for design. The Straw Bale Eco Center is one groups ongoing effort to address this challenge.



The Eco Center is intended to promote awareness of issues related to sustainable development to a broad audience which includes  students, grade school students, building professionals and the general public. The project was designed, documented and constructed in collaboration with three separate interdisciplinary groups of BSU Students, and was initially funded with a $10,000 grant from the Environmental Protection Agency. The Eco Center, completed in 2009 after raising close to $60,000 through a combination of grants, donations and industry partnerships, represents the first load bearing straw bale building as well as one of the first carbon – neutral public facilities in the region. The project generates all of its own power and monitors the performance of alternative energy systems on site, including photovoltaic, solar hot water and wind power.



The Eco Center is located on an 80 acre “field station”, sited at the edge of a restored prairie in. One of the primary uses of the facility is to stage student and community environmental tours of the site. In addition to satisfying the practical need for a staging area for these tours, the Eco Center is itself an educational tool; intended to extend the discussion of the natural landscape to that of the built environment and highlight the potential for synergies between the two.



The Eco Center finds its aesthetic identity, its sense of beauty, by navigating within a very specific set of criteria generated by the site, the project “circumstance” and the sustainable agenda. Contributors explored and came to understand the potential for design in the materials and assemblies, came to understand the act of making and the act of design as being inextricably intertwined, and in so doing created a work that is genuine and rooted to its place. Contributors have created a work which attempts to frame a way of thinking that is simultaneously local and global, a small work which aspires to share a large message with a broad audience.

In 2020 We Can Wear Sony Computers On Our Wrist

Our present need for internet connectivity is so profound that secondary devices like the Nextep Computer are bound to happen. Developed to be worn as a bracelet, this computer concept is constructed out of a flexible OLED touchscreen. Earmarked for the year 2020, features like a holographic projector (for screen), pull-out extra keyboard panels and social networking compatibility, make the concept plausible. Ten years from now is not too far away, so how many of you think we’d be buying such gadgets?

Hacker’s Guide to Tea

Hwang Cha Yellow Tea

Korean Hwang Cha (Yellow Tea)

TL;DR:



  • All tea comes from the camellia sinensis plant. If you are drinking something that did not come from this plant (chamomile, mint, tulsi, rooibos, etc) it is not tea).

  • White, Green, Oolong, Yellow, Black and Pu-erh teas all come from the camellia sinensis plant and the type of tea is determined by the processing methods used on the plucked leaves.

  • Tea contains L-theanine, an amino acid that promotes mental acuity. The combination of L-theanine and caffeine creates a sense of “mindful awareness.”

  • Tea can be prepared in any vessel by steeping the leaves directly in hot water as long as you strain the leaves out of the water before drinking.

  • The more oxidized the tea leaves are, the hotter the water temperature should be when steeping.


TL:


In addition to caffeine, tea contains an amino acid called L-theanine. “Several studies from Japan and the UK have shown that consumption of 50mg of L-theanine increases alpha wave activity in the brain, with the maximum effect occurring about 80 minutes after consumption. This amount is equivalent to approximately three cups of tea. Alpha waves correspond to a relaxed-but-alert mental state, and believed to be an important part of selective attention (the ability to choose to pay attention to something and avoid distraction by other stimuli)” [source: http://www.teageek.net]. L-theanine in tea produces a type of “mindful awareness” not evident in coffee. This is what prevents the 3pm “coffee crash.”



Theanine

This makes tea an important tool for maintaining mental perspicacity for hours of coding, late night performance, or for getting through those bleak morning hours.

Let’s get this out of the way – tea bags suck. Actually, most mainstream tea sucks. Mainstream tea is low quality, blended, and sometimes contains cheap flavorings. There are countless tea shops out there that buy directly from small farmers that produce small crops each season and likely process the tea by hand.

What You Need to Know


Camellia Sinensis: The Tea Plant

Camellia Sinensis: The Tea Plant

  • All true tea comes from the camellia sinensis plant [photo above]. White, Green, Oolong, Yellow, Black, and Pu-erh teas all come from this plant.

  • Loose tea can be steeped multiple times. Some teas can be re-steeped 20 or more times. The flavor is gradually extracted from the leaves with each subsequent steep.

  • When shopping for tea, look for companies that offer information about where the tea is from, how it was processed, who grew it, and most importantly—when the tea was harvested.


Finum StrainerWhen steeping the tea, be sure the tea can flow freely through the water, this rules out tea bags, tiny tea infusion baskets, tea balls, etc. Ideally, pour water directly over the tea and then strain before drinking. If you must use an infuser, a large finum strainer [photo left] works nicely and still allows for proper water flow.

Depending on the type of tea you are steeping there are two important variables you must pay attention to: water temperature, and steeping time. I’m assuming you are using good water, as tea is 98% water – using a strong chlorinated water would be a bad idea. In general, hotter water must be used for highly oxidized teas. Remember, you are preparing a drink that you should enjoy, so always take tea instructions with a grain of salt. Experiment often to discover the “sweet spot” with your teas and remember—a good tea is a forgiving tea. If your tea is bitter, reduce the steeping temperature. If your tea is too weak, increase the amount of tea leaves used or increase the steeping time.  Here are some guidelines I send out with orders for Chicago Tea Garden



















































TeaWater

Black212ºF1 min1 min1.5 min1.5 min
Pu-erh212ºF30 sec30 sec45 sec1 min

It is not necessary to get real serious about the steeping temperatures, for 195, boil water, take it off the stove, and wait about a minute. For 170, wait longer. Remember, experiment often.

If you want to get serious about steeping your tea, use a yixing pot, or a gaiwan. If you need energy, consider drinking matcha — a suspension of powdered tea. You are actually consuming the leaf so the health benefits and energy received from matcha are greater than that in other teas. If you need peace, study thegongfu tea ceremony [pictured below]– it is a great way to relax so you can enjoy and appreciate the tea.

A fresh tea should have a shelf life of approximately two years, a lightly oxidized tea might become stale quicker. Store your tea away from light, heat air, and any strong scents.

Thin Film Solar Catching Up To Crystalline Panels On Efficiency?



The National Renewable Energy Labratory (NREL) recently tested thin-film solar modules made by MiaSolé, and verified that their energy conversion efficiency rate hit 15.7 percent, up from 14.3 percent last year.

The company boasted about the number, and several news outlets touted the results. Does it mean the performance gap between thin-film and crystalline solar modules is closing? Could thin-film take a bite out of the market for crystalline panels in the U.S., soon?

Clean tech analysts and engineers believe that thin-film solar is not likely to catch up to crystalline in terms of efficiency any time soon. Neither will thin-film solar modules steal market share from crystalline in 2011, they predict.

Thin film solar modules are made by a huge number of companies today including: Abound Solar, Best Solar, First Solar, Konica, LG Electronics, MiaSolé, PrimeStar Solar, Nanosolar, Sharp and Uni-Solar. Not all thin-film solar is created equal, however.

Today’s typical thin-film modules look like sheets of glass (image, below). Crystalline modules also look like sheets of glass but are thicker, and framed in metal (image, top of post). Uni-Solar’s thin-film modules, interestingly, are flexible and have a stick-on backing.



A senior analyst with Lux Research, Ted Sullivan, points out that there are a variety of thin-film solar cells in production today: MiaSolé uses copper indium gallium diselenide (CIGS) solar cells in their product; FirstSolar uses cadmium telluride (CdTe) cells, which are dominant sellers in the U.S. thin-film solar market today; while Konica and Sharp use silicon cells.

Of all thin-film technologies, CIGS modules demonstrate the greatest energy conversion efficiency, and power output per square meter. CIGS cells require less energy for production than crystalline cells. Thin film in general requires less expensive semiconductor material, and fewer process steps than it takes to make crystalline modules, according to NREL research.

Manufacturing costs keep the price of thin-film modules comparatively low, today. Solar analyst Sullivan explained, however, that thin-film solar manufacturers face a different challenge:
“There’s kind of a consistency issue for all [thin-film] players. Ideally, you want modules to be produced identically, so there is no variation between each module [especially once they're installed out in the field].

CIGS thin-film solar production is the most highly variable as it involves four metal alloys and processes where impurities and other things can have a negative impact on the resulting product.”

MiaSolé’s 15.7 percent rating, he noted, is important because it illustrates that CIGS thin-film solar technology is comparable to the current, low-end potential energy of silicon polycrystalline panels.

But thin-film solar manufacturers have to procure a greater variety of metals from sources far from the United States (mostly China today) leading to market concerns over trade war potentiala shortage of metals, and unfair labor and damaging environmental practicesof mines.

Meanwhile, crystalline module prices are coming down a bit as production ramps worldwide. A solar engineer at GridPoint in Houston, Texas, John Gardner says both technologies have their uses, even in a world where they cost about the same.

GridPoint sells and installs software, hardware and services to help organizations switch to clean energy in any form that will work best for their facilities and operations. Gardner says the company uses both thin-film and crystalline solar for client projects, but more crystalline so far, including in power generating systems they’ve installed for federal agencies, retailers and restaurant chains.

Gardner outlined some of the best uses and limitations of each technology:
“In a typical home installation, you’ll have a certain area, or amount of roof space where you want to place solar panels. If there’s a limited space, you’ll probably want crystalline to get the most power per square foot.

Structure or aesthetics sometimes dictate what you are able to install, though. We worked on one project involving a roof that could not handle the weight of crystalline panels.

Or let’s say you’re building a skyscraper with a glass façade. If you integrate thin-film type solar panels there, your building is now generating power with the same skin that was otherwise just glass.

If you have near unlimited space, say to build a solar farm out in the desert, you could consider thin-film because the modules cost less per watt. That said, labor costs to install a higher number of modules could offset the price difference, and crystalline might make more sense.”

On Monday, the world’s largest manufacturer of solar panels— SunTech Power Holdings Co.in Wuxi, China— announced it expects to have crystalline modules that have 22 percent conversion efficiency out in the market in the next three years.

That’s one more reason, Sullivan suggests, crystalline panels will remain dominant in 2011, especially in applications where space is limited. “Most of the thin-film technologies out there today will never get to silicon crystalline efficiency, which has just been around longer and is still seeing improvements,” he concluded.

Stoneage Style House – Mountain Home in Portugal

Who knew the Stoneage would make a roaring comeback?? Check out this amazing stone house exterior, tucked in a peaceful pastoral setting in Nas Montanhas de Fafe, Portugal. This hillside house boasts unobstructed, untarnished views of the grass-covered mountain and valley. This unusual structure isn’t your typical house, featuring an irregular exterior, but some traditional “house” elements were incorporated – namely, its charming windows and a shingled roof that stands out among these seemingly untouched, natural surroundings.
