I’m sitting here in my dining room trying to get at least a little work done, though.  Looking around my house, I remember all the green building decisions we made when we renovated last year.  Right from the beginning, we did our best to reduce, reuse, and recycle (thanks for your good comments on that post!). Some of these choices might save us money over time, but our main motivation was that green building and home location is just the way it should be done:

• zero-VOC paint and low-VOC caulks and adhesives
• a high-efficiency Energy Star furnace (and air conditioning, for when summer returns), plus an Energy Star dishwasher to replace the original that died a month after moving in.  We kept the other appliances, and will replace them with Energy Star units as they stop working.
• Energy Star double-paned windows and doors
• light-colored roof shingles to reflect the hot summer sun
• compact fluorescent light bulbs (other than on my youngest child’s night table because she keeps breaking them)
• bamboo floors where the old floors couldn’t be saved, and refinished hardwood and parquet that could (like the appliances, why throw out stuff that works?)
• kitchen countertops made of recycled glass and bamboo
• Watersense water-efficient sinks, toilets, and showerheads
• blown foam insulation that’s keeping us nice and toasty.

We also put the old kitchen cabinets in our laundry room and basement, and donated a lot of extra materials and fixtures to a local organization that sells them again.

The house’s location is also pretty green, since I can easily walk or bike to the subway.  Our kids ride the bus and walk to school, and we’re a 10-minute walk to the library and a small commercial district with several restaurants, a drug store, and our favorite: a local ice cream shop.

Of course, sometimes it’s hard to find a home near public transit, and not every building option is available or affordable.  For example, while wood and other materials were greener, they were too expensive compared with vinyl windows.  But we did as much as we could.

We’re happy with our choices, but we enjoy discussing them, too.  What’s your favorite green feature of your home?

About the author: Jeffrey Levy is EPA’s Director of Web Communications.

Our building is environmentally friendly and provides daily opportunities for us to practice stewardship. Some features of our building that help us decrease our impact include:

• Extensive use of daylight to reduce need for artificial light
• A vegetated green roof to control storm water and decrease urban heat island effect
• Waterless urinals and low-flow plumbing fixtures to decrease water use
• High recycled content materials throughout the building
• Proximity to public transit

However, it is not enough to simply build a green building; a big part of the equation is how the building is operated and the behavior of the occupants. Region 8’s Environmental Management System helps us improve our performance by quantifying and managing the impacts of our operations (e.g., electricity and water use, waste generation and transportation) and taking actions to reduce those impacts.

The green design, construction, operation and maintenance of 1595 Wynkoop, combined with close attention to our collective actions, help EPA in our efforts to practice what we preach.

Working in a green building is the only way to work in my mind. I have more energy throughout the day which I attribute to the environmentally healthy aspects of our building. I have the pleasure of knowing my work day has also been less of an impact to the environment.

However, this greenversation points to the need to further address the proper disposal of other household items that may have hazardous content—batteries, electronics, even cell phones, to name a few. The title of my blogs, “When in doubt, throw it out,” was not meant as a blanket statement for all solid waste management. There are guidelines for the proper disposal and recycling of items with hazardous waste. So, I recommend that you visit the following Web pages to obtain additional information on the important issues you mentioned so we can all work to protect the environment where we live, work, learn and play.

Here are some useful Websites for the disposal and recycling of the following products:
batteries; mercury-containing light bulb recycling; electronics; cell phones; used oil; and general household hazardous waste.

Thank you for your input. Keep it coming.

Sin embargo, durante esta charla ambiental se hizo claro la necesidad de abordar la disposición adecuada de otros artículos caseros que podrían tener contenido peligroso como baterías, equipo electrónicos y hasta los teléfonos celulares, entre otros. El título de mis blogs “Si tiene dudas, échelo a la basura” no representaba una declaración generalizada para atender la necesidad del manejo de desechos sólidos. Existen normas para la disposición adecuada y el reciclaje de artículos con desechos peligrosos. Por eso recomiendo que visiten las siguientes páginas Web para obtener información adicional sobre estos importantes asuntos que ustedes han mencionado para que todos podamos trabajar juntos para proteger el medio ambiente donde vivimos, trabajamos, aprendemos y jugamos.

He aquí algunos sitios Web útiles sobre la disposición y reciclaje de los siguientes productos: baterías; reciclaje de bombillas con mercurio; efectos electrónicos; teléfonos celulares; aceite usado de motor; y desechos caseros peligrosos. Gracias por su insumo. Sigan enviando sus comentarios.

Lately, John Godleski has spent a lot of time underground.

When I visited Harvard in December though, he surfaced for a chat with me about his unique research.

Along with colleagues at the Harvard Particulate Matter Research Center, Godleski has set up air pollution monitoring equipment inside a busy tunnel in the Northeast.

Part of the Toxicological Evaluation of Realistic Emission Source Aerosol, his study aims to assess differences between the health effects of exposure to particles directly from car exhaust (primary), and particles from exhaust that have transformed in the atmosphere (secondary).

The underlying hypothesis of the project is that breathing in particles that come directly from a vehicle might induce different health effects than breathing in particles that have spent time in the atmosphere, where they come into contact with sunlight.

To test the hypothesis, Godleski and his colleagues developed a photochemical aging chamber that essentially mimics real-world atmospheric conditions with simulated sunlight.

Exhaust from cars is fed into the chamber first with the artificial sun-lights switched to “off” and to then to “on.” This produces two types of output: exhaust with just primary particles (lights off), and exhaust with both primary and secondary particles (lights on).

Project scientists then conduct lab studies to look for differences in resulting health outcomes.

Preliminary findings suggest that the “lights on” particles, representing particles that have come into contact with sunlight, cause more lung inflammation and more potentially harmful oxidative activity in the body.

Since secondary particles in the air are ubiquitous, understanding their health impacts is extremely important.

“Though some people are involved in what directly comes out of a vehicle or a power plant, everybody is exposed to what happens to those particles once they are in the air,” Godleski explained.

Collection of exhaust particles directly from the tunnel makes this study especially representative of real-world particle exposure.

“If we go to a tunnel,” he continued, “we can get a mixture of vehicle output—we can get cars, we can get trucks, and we can get something very representative of what people ultimately may breathe. It gives us access to a mixed vehicle effluent in a way that nothing else does.”

This research is a critical step toward understanding the health effects of real-world airborne particle exposure. We will continue to report findings as Godleski continues to dig for answers.

This weekend, I saw people releasing bunches of helium balloons from the second story windows of a club, just after I had gotten off the Metro and heard “If you see something, say something.” So, without thinking, I ran over to the building and shouted to the people that they shouldn’t be littering and that whales were going to eat the balloons and die (see p. 21). It wasn’t my best developed message or delivery, and I am no whale expert! Overall, I doubt it did much to advance the environmental cause, because a shrill shout turns people off more than it educates, engages or convinces them.

So, I began to wonder if getting the delivery right was the only barrier to a successful “If you see something” campaign for an environmental issue, such as reducing littering or global warming pollution. Like national security, environmental issues often feel too large for people to have an impact. And, it’s pretty easy to spot people littering, and even identifying global warming pollution could be done even if it is a bit more difficult. That said, approaching a stranger who is littering might be different, because it is difficult to avoid explicitly or implicitly reprimanding them. Reducing global warming pollution to an even greater extent delves into peoples’ personal choices and lifestyle, and unlike littering, there are no laws against leaving all the lights, televisions, and other appliances on in your home or driving your large inefficient vehicle around the block twenty times looking for a parking space. (Although there are great voluntary programs run by EPA and Department of Energy to promote the alternative behaviors for which I have provided links.)

Perhaps our society’s experience with smoking can offer lessons on the topic. Over time, it has become more and more unacceptable to smoke in public places, and people feel more and more empowered to ask people not to smoke in their presence. Maybe creating excessive global warming pollution will rise to that level, but we’re a ways from there now.

Do you have ideas for environmental issues that might work with the “If you see something, say something” framework?

Thanks to the skill, professionalism, and patience of our pilot, we landed with a portfolio of several hundred stunning aerial photographs to support science and outreach efforts, a far better understanding of EPA ecosystem services research, and a deeper appreciation for the spirit of collaboration between EPA and the U.S. Fish and Wildlife Service.

Thanks to Ray’s quick smile and generous spirit, the trip was both fruitful and fun.

Last week, I learned the tragic news that Ray, along with his passenger biologist David Pitkin, died on January 17 when their plane went down in a wooded area west of Philomath, OR. The two were returning from a day spent flying over estuaries along the Oregon coast, counting ducks, geese, and swans for an annual mid-winter waterfowl survey.

Even though I only spent the better part of an afternoon with Ray, he made a big impression. His love of flying and wildlife were evident. As a wildlife aficionado and former U.S. Fish and Wildlife Service employee myself, I loved hearing his tales of survey flights over wilderness areas and National Wildlife Refuges from Chesapeake Bay to Alaska. He even extended our first flight a few minutes to see if he could find a grey whale to show us off the coast of Newport. (No such luck.)

One of the best parts of my job is getting to work with people—scientists, photographers, and pilot-biologists included—who clearly love what they do. Ray’s passion for flying and wildlife conservation were obvious, and infectious. The flights he took us on were the highlight of a great week, and I feel fortunate to have had the opportunity to work with him.

I offer my heartfelt condolences to the families, and many friends and colleagues of Ray Bentley and David Pitkin.

I discussed the use of toxic metals in some toy jewelry and metal trinkets produced overseas. As the title suggested, I recommended if you were concerned over the potential toxicity and risks of these toys, the best thing to do was to dispose of these products. However, I didn’t address another legitimate concern: is it safe for the environment to simply throw these articles in the trash? Well, the answer is yes. I will explain why.

First of all, I would like to thank two individuals, Mauricio D’Achiardi and Joan, for their comments last week. They actually posed the question regarding the proper disposal of these toy trinkets. Since I didn’t have an answer, I consulted with our experts in the Office of Resource Conservation and Recovery. The guidance is: “Consumers can check with their local recycling facility to see if they collect these kinds of contaminated jewelry and trinkets. To find a local recycling facility, they can go to www.earth911.com . If their local recycling facility doesn’t take these articles, consumers can go ahead and throw them in the trash. Our modern landfills are made to be able to hold such contamination without leaking it into the environment.” So, we can dispose of these safely.

For more information on the disposal of waste, please visit our Website. For information on product recalls and keeping people safe in and around the home, visit the US Consumer Product Safety Commission’s Neighborhood Safety Network. And please keep those comments coming. We all can learn from this Greenversation.
