This past summer, the world’s eyes turned to Beijing to watch the Olympics. With that attention came more scrutiny to the many environmental issues resulting from China’s long economic boom.

Two facts demonstrate the mix of hope and challenge that China represents for our future. First, carbon dioxide emissions (the greatest contributor to climate change) are growing rapidly in China, to the point that some estimate China has already surpassed the U.S. as the world’s leading emitter. Yet China also is projected to have surpassed the rest of the world as the leading producer of clean, renewable energy – including wind, solar and hydropower (according to the Renewables 2007 report sponsored by Germany).

I had the privilege of visiting this remarkable country this past April, as part of an EPA delegation meeting the Chinese Ministry of Science and Technology (MOST) in Beijing. On this trip, I got to meet people who are working to make green building a reality in China, from the government, major universities (Tsinghua, Shanghai Research Institute of Building Sciences, Huazhong University of Science and Technology) and even a government-supported non-profit (Administrative Center for China’s Agenda 21).

While there are vast differences between the situations of our two countries – chief among them the major environmental crises facing China and the disparity between our governmental systems – I was struck by a few of the similarities. There, as here, the status quo too often prevails against the wisdom of making our buildings more efficient in their use of energy, water and materials, and healthier to live in and around. There, as here, progress often hinges on the initiative of a few heroic individuals willing to stick their necks out to try something new and innovative.

I got to meet several such individuals on my trip, working on such projects as the Eco-House that will be showcased at the Shanghai World Expo in 2010. They were eager to learn more about EPA programs like Brownfields and ENERGY STAR, and about the progress Americans have made in establishing green building as a major trend in the U.S.

In the Olympic spirit, I’d like to see the US engage in strenuous but healthy competition with China, to see which of our countries can move faster toward discovering and applying the greenest technologies – in our buildings, vehicles, factories and more. Call it the race for the Green Medal – and let the games begin!

We are fast approaching the end of hurricane season 2008. With the exception of hurricane Ike, the US territories and mainland have been largely spared the ravages of storms past. However, hurricane season got me to thinking, how can we develop construction materials that are sustainable while, at the same time, they will withstand hurricane force winds and rains of the likes of Ike, Katrina, Georges, and Andrew, to name a few?

I think the Agency has made great strides in supporting technological advances in green building, enhancing energy and water efficiency. However, I wonder how we can take those green benefits to areas that are more susceptible to nature’s onslaught during hurricane season?

For example, in Jeffrey’s blog from Hawaii, he noted how little air conditioning was used in many of the homes. However, the Hawaiian Islands are not in the paths of the storms that come from Africa to the Americas like the Caribbean Islands. We’ve seen Brenda’s efforts to reduce the carbon footprint in Puerto Rico, but I still haven’t seen any green substitute for good old concrete when it comes to withstanding hurricane force winds.

So, I would like to use the Web to start a greenversation. I want to consult with experts in this area. Are there green materials stronger than hay and sticks yet greener than bricks? Let’s find materials that will not allow the bad hurricane wolves to blow our houses down. Looking forward to your comments.

¿Resistiría la embestida?

Nos estamos acercando rápidamente al final de la temporada de huracanes del 2008. Salvo el huracán Ike, los territorios y continente estadounidenses se libraron de los azotes de tormentas pasadas. Sin embargo, durante esta temporada de huracanes me he puesto a pensar sobre cómo podemos desarrollar materiales de construcción que sean sostenibles y que a la misma vez puedan resistir el impacto de vientos huracanados y lluvias torrenciales como los Ike, Katrina, Georges, y Andrew, del mundo?

Pienso que la Agencia ha logrado grandes avances al apoyar tecnologías en edificios verdes, la eficiencia energética y la conservación de agua. Sin embargo, me pregunto si podemos llevar esos beneficios ambientalistas a las áreas que sean más susceptibles a los ataques de la naturaleza durante la temporada de huracanes?

Por ejemplo, en el blog de Jeffrey desde Hawai, destacó cómo limitaban el uso del aire acondicionado en muchos hogares. Sin embargo, las Islas Hawaianas no se encuentran en el paso de las tormentas que salen de África camino a las Américas como están las islas del Caribe. Vimos los esfuerzos de Brenda por reducir la huella de carbono en Puerto Rico, pero todavía no he visto un buen sustituto verde al consabido concreto cuando se trata de resistir un vendaval huracanado.

Por lo tanto, quisiera usar esta página para comenzar una conversación verde, Greenversation. Quisiera consultar con expertos en esta área. Como en el cuento de los tres cerditos, ¿acaso hay materiales verdes que sean más fuertes que la paja y la leña, pero más verdes que los ladrillos? Encontremos materiales que no permitan que los malos lobos huracanados derriben nuestros hogares. Me encantaría leer sus comentarios.

So what does it really mean to be green?

That may sound like one of those dreaded philosophical questions you have to ask of a white-bearded guru sitting cross-legged and barefoot on a mountaintop.

But as green becomes the hottest marketing term around, you do have to ask what it means. As everyone from your dry-cleaner to your gas station tries to convince you that they’re the greenest, how do you know who is and who isn’t?

The Federal Trade Commission, which monitors marketing claims, is looking into this issue as it updates its “Green Guides” . But the answers are not always as straightforward as we might like.

In my area of expertise, green building, EPA is considering how we can help this field better define itself. Here are a few of the questions we’re grappling with:

1) Essential components: The popular green building rating systems in the marketplace provide great flexibility to trade off among many strategies, from low-flow toilets to low-emitting paints. But are there any elements so essential that they shouldn’t be traded off – like energy efficiency?
2) Levels of green: A related question is how far you need to go to be called green – for instance, if a company changes its light bulbs to more efficient compact fluorescents, but does nothing to improve its inefficient heating and cooling system – how green can it really claim to be?
3) Lifecycle impacts: One of the most complicated exercises in the sustainability field is life cycle analysis (LCA). An LCA is the Herculean task of comparing the environmental and health impacts of a product throughout its “life” – say, from when trees are cut down or metals mined, through manufacturing and use, to ultimate disposal. An incredible challenge – and yet how can we know what’s truly greenest until we figure out how to do this type of analysis effectively?
4) Maintaining green: Finally, how long will the building or product remain green, and what maintenance will it need to keep that nice green glow from fading?

Maybe some day all of the answers will be easy to find. In the meantime, when you hear green claims, make sure to ask a lot of questions, compare and contrast products, and request as much background information as possible.

But please don’t attempt to climb any treacherous mountains looking for green gurus. No need, actually – these days, most gurus have email.

We’ve been living in our “new” house for nearly 14 years. With the normal wear and tear of daily living, we’ve made our share of repairs, plus we’ve purposely made some changes for energy and water saving purposes.

Several years ago, we bought all new major appliances with the Energy Star label. In our effort to reduce our carbon footprint, we took the pledge and changed all the lights to Energy Star light bulbs. (In the kitchen alone—we have 12!) That didn’t seem to be enough to cut the energy bill, so last summer, we changed all the windows at home to high performance Energy Star windows. The draftiness had been sealed. We did experience greater temperature stability in the home, yet those energy savings were not yet there. Forget about the rising electric bill costs, that was a whole other issue. So after some procrastination, we finally purchased a new air-conditioning/heating system with the Energy Star label AND the Energy Star programmable thermostat. Combined with our previous updates, that really made the difference! We are finally feeling at home and in our energy bills the long promised and awaiting benefits. Our energy consumption has dropped about 40 percent.

Having addressed the electric bill, we had to tackle another area—leaking toilets. Yes, I know it’s not an appealing subject, but, we have five toilets at home and three were leaking quite often. According to our stats, “a leaky toilet can waste 200 gallons of water per day”—you do the math. That’s a LOT of water wasted.

I learned about the WaterSense program through EPA and found out that the new toilets with the high-efficiency WaterSense label were finally available in the Maryland area where we live. We studied various options. We considered the dual flush toilets that we’ve seen in Europe and more recently in EPA’s Potomac Yard green building, but we finally opted for single flush toilets that use 1.28 gallons per flush and we couldn’t be happier. They do the job and we’ve put a stop to those leaky toilets, finally.

So, with the repairs in the home and greenscaping techniques in the garden, we’re trying to assume our green responsibilities starting at home

Haciendo reparaciones verdes

Hemos estado viviendo en nuestra casa “nueva” por casi 14 años. Con el ir y venir del diario vivir, hemos tenido que hacer algunas reparaciones y nos hemos propuesto a hacer algunos cambios a fin de lograr ahorros de energía y agua.

Después de unos años, compramos todos nuestros principales enseres electrodomésticos con la etiqueta de Energy Star. En nuestro esfuerzo por reducir nuestra huella de carbono, asumimos la promesa—– y cambiamos todas las bombillas (o focos) a bombillas de la etiqueta Energy Star. ¡En la cocina nada más tengo 12!) Eso no fue suficiente para reducir la cuenta de electricidad y el verano pasado cambiamos todas las ventanas en la casa a ventanas de alto rendimiento Energy Star. Logramos reducir escapes de aire alrededor de las ventanas. También mejoramos grandemente la estabilidad en la temperatura en la casa, pero los anticipados ahorros todavía no habían sido realizados. (Dejemos aparte las cuentas de electricidad en alza, ese es un tema aparte.) Después de posponer la decisión, compramos finalmente un nuevo sistema de aire acondicionado y calefacción de Energy Star Y el termostato programable de Energy Star. ¡Combinado con las mejoras que habíamos hecho con anterioridad, por fin vimos la diferencia! Finalmente estamos sintiendo en la casa y en nuestras facturas de energía los beneficios prometidos y tan anticipados. Nuestro consumo energético ha bajado en un 40 por ciento.

Después de abordar el tema de la cuenta eléctrica, entonces abordamos otra reparación importante—los inodoros que estaban perdiendo agua. Sí, sé que no es un tema atrayente, pero, con cinco inodoros en la casa, y tres que estaban perdiendo agua frecuentemente, se imaginan. Según nuestros datos, “un inodoro con fugas puede desperdiciar 200 galones de agua al día, saque las cuentas. Esa es MUCHA agua desperdiciada.

Me enteré del programa WaterSense — mediante la EPA y encontré que los nuevos inodoros de la etiqueta de alto rendimiento WaterSense por fin estaban disponibles en el área de Maryland donde vivimos. Estudiamos varias opciones. Consideramos los inodoros de cadena dual que habíamos visto en Europa y recientemente en el edificio verde de EPA de Potomac Yard, pero finalmente optamos por un inodoro sencillo que utiliza 1.28 galones por tirada y estamos muy satisfechos. Están realizando su labor y por fin terminamos con los escapes de agua en los inodoros.

Por lo tanto, con las reparaciones y las técnicas de jardinería verde en el jardín estamos tratando de asumir nuestras responsabilidades hacia el medio ambiente empezando en nuestro hogar.

About the author: An aspiring amateur plumber, Aaron Ferster is the science writer-editor for EPA’s Office of Research and Development.

A few weeks ago my wife and I met with one of Johns Hopkins’ top surgeons to discuss a second cochlear implant (CI) for our youngest daughter, who is deaf. She had CI surgery for one ear six years ago, and there are significant potential benefits in getting one for her other ear. The doctor talked about improvements to surgical techniques, new sound processing strategies, and advances to the latest generation of CIs, which truly represent the height of bio-technology.

After the appointment we drove home and I spent the afternoon on something with a decidedly lower gee-whiz factor: draining and removing the bathroom toilet so I could turn it sideways, then upside down so a small scissors that had accidently dropped in would wind its way through the traps and twists and drop out. It worked. But perhaps more importantly, it gave me something to do while waiting for the doctor’s office to call with a surgery date. All in all, not a bad day.

I had another good day thinking about the astounding diversity of technology that surrounds us while attending a session entitled “Green Building Research Needs and the Promise of New Technology” at this year’s EPA Science Forum. The session was chaired by Ken Sandler, who wrote about his efforts to establish a new EPA strategy for green buildings on Greenversations. The panel discussion included exemplary case studies of the latest research and design in lowering a building’s environmental footprint when energy savings and sustainability are priorities.

The talk was inspiring, and like anyone with energy bills to pay, I’m eager to see the advent of low-impact, carbon-neutral homes and office buildings complete with the latest real time information technology guiding energy consumption choices. But like turning the toilet upside down while waiting for the phone to ring, I’d like something I can do today while the green building revolution continues to gathers steam. Luckily, a quick web search reveals a bunch (including a few excellent ones that have already been covered on this blog), including: installing compact florescent light bulbs, greenscaping the yard, biking to work, making a rain barrel, buying energy star appliances, and planting shade trees.

Now if only someone would invent scissors that dissolve in water. Oh well.

At EPA, we strive to help people make the environment part of their everyday decisions. But how can we tell when we’re succeeding?

In truth, we often can’t. But sometimes the evidence of change is hard to miss.

Take green building (Web site or video) – making buildings and their sites better for the environment and health. It’s an issue on which I’ve worked for a decade, and I’m now leading efforts to establish a new EPA strategy on the subject.

Yet for years, I would draw blank stares when mentioning “green building” in conversation. Some people would even ask if it meant painting buildings green.

And then, suddenly, nearly everyone had heard of it. My Dad was sending me articles on green building from Newsweek. I would mention it at a barbecue and people would come up to me and say, yes, we’re looking to green our homes, tell us how!

Green building seems to have reached its tipping point. But how do such things happen? If there’s a formula to make sustainable practices bloom, we’d like to get our hands on it.

In fact, we’ve seen such phenomena before. Take recycling. In 1988, only 1,000 communities in America had curbside recycling. Just 8 years later, that number had leaped to 9,000. Why? One reason was that in 1989, responding to public concern, EPA set a goal for the US to recycle 25% of its municipal waste.

This helped set off a competition among states to set their own recycling goals. In response, systems were established to recycle a variety of materials. The engine of recycling got going – and keeps on humming.

With green building, the story is different. Since the early 1990s, EPA has successfully pushed voluntary programs covering many aspects of the built environment – energy, water, indoor air quality, products, waste, smart growth and more. Other groups began to put these pieces together in holistic, market-based programs.

The U.S. Green Building Council, a leading non-profit, has its own eye-popping numbers on the transformation they helped bring about. From 2000 to the present, their member organizations went from 570 to over 15,000, the number of buildings registering to use their LEED green building rating system from 45 to 21,000.

So does this mean our work is done? Hardly. The green building field has needs that range from research to stronger standards to more public education and partnerships. We plan to work with a wide variety of groups to help tackle all of these challenges.

But there are many advantages to reaching a tipping point. Those years of struggling in obscurity have given way to lots of new doors opening up. And it’s nice to get fewer blank stares at parties.
