Green Driveway Path Options
A while back, I wrote about Green Driveways and Paths, which ended up being a pretty popular article. I figured that it would be helpful to see your options when it comes to porous surfaces, permeable paths and eco-friendly driveways.
Green driveways not only are more pleasant to look at, they also can reduce urban heat retention, reduce CO2, reduce runoff, improve drainage and aquifer recharging, provide some water filtration and more! They can also be cheaper in the long run over asphault (resurfacing costs and crack repairs) and concrete (repairing cracks, staining) not to mention preventing washouts and pot holes.
Systems already embraced in Europe typically last over 20-30 years, with little to no repairs or maintenance. The main options for green driveways are using some sort of permeable surface along with turf, gravel or ground cover to enhance the beauty and green factor.

Eco-Development and Sustainable Renovation
I’ve noticed an interesting trend lately. The renovation of old buildings. Gorgeous old buildings gutted and rebuilt from the inside-out, as green and sustainable new structures.
An exciting (and well-publicized) example of this is the Sanctuary development on Capital Hill in Seattle.
The original church was built in the early 1900s and has been a distinctive landmark of the neighborhood for years. Through the renovation of this historical icon, ecological- minded urban residences are being created.
The preservation of the beautiful building was a cornerstone of the project planning. Architectural details, bricks, wooden pews, flooring and windows were repurposed and used within the new residential development as stairs, detailing, in-fill and patching. New sustainable aspects of the housing itself include dual flush toilets and tankless water heaters. › Continue reading
Energy Efficient Windows
Winter: tis the season to be jolly. Christmas and Valentine’s day have already come to pass, but the season hasn’t lost all of it’s festivities for those of us enjoying the Winter Olympics. Some time during the beginning of each month though, in spite of how joyful the season may be, you’re bound to get an envelope in the mail that’ll bring you down from all that cheer. Inside the envelope, you’ll find a letter with a lot of fine print and a very clear number representing how much money will be going to go towards paying off the additional heating expenses that every Winter brings along with, the Winter hangover.
Environmentally sound technology has advanced though to the point where you can stay warm in-doors without paying as much of the annual extra costs of heating utilities and without causing unnecessary harm to the environment. It’s a win-win situation in the form of a window material that won’t even clash with your drapes.
The technology is called Low-emittance coating and is applied to the glass during the manufacturing process but the science behind it is pretty simple. When your home is warmed up, eventually things will cool down (it’s why you have to keep the heater on over extended periods of time) as the heat radiates. The heat leaves in the form of infrared radiation, and these microscopic layers work to prevent that by only allowing specific frequencies through. Best of all though, it can work both ways. So in the Summer the same coating that kept heat in during the winter, can keep heat out (diminishing the need to keep rooms regularly air-conditioned).

Eco-Friendly Bark Shingles Home Siding
Thinking about re-siding your home? Take a look at this eco alternative. Just like a trees own weather proofing, these bark shingles insulate, protect, and are virtually maintenance free. It is made up of tulip tree bark waste from timber operations that would otherwise get burned, mulched, or left to rot.
Lasting up to 75 years, renewable, sustainably harvested and containing no chemicals, it is quite possibly the greenest siding on the market today. The textured look only adds to its appearance and acoustic properties, blocking out sounds much like another bark, cork.
North America’s Largest Living Green Wall
PNC now holds the title for the largest living green wall in North America currently hanging on the exterior of their Pittsburgh headquarters building located at One PNC Plaza. With approximately 14,448 plants covering 602 modular panels, the 2,380 square-feet living mural really livens up the 30-story building.
The eight varieties of plants, installed by locally sourced (within a 500 mile radius of downtown Pittsburgh) materials and labor, only need 15 minutes of irrigation per week. Not only does it look pretty, its also doing some work- reducing the ambient temperatures of the south-facing wall by 25%.
Not only that, PNC has constructed more green United States Green Building Council LEED certified buildings than any other company in the world with a count of 64 Green Branch locations and two office buildings.
Whole House Lighting Control System
Great lighting can really make a house feel like a home. While we tend to focus on the energy efficiency and design of lamps and bulbs, often we neglect to consider the actual electrical system in the house. Whole House Lighting Control System by Verve Living Systems brings a whole new element to eco-friendly lighting.
A wireless lighting system that works via radio frequencies without the need for batteries, it works by routing all lighting to a programmable central controller. Each switch transmits a ‘blip’ of a radio transmission to the central hub up to 300 feet away, get this: by using the energy from the act of flipping the switch. That’s right, the switch itself powers the transmission without needing batteries or its own power source, so they are completely independent and self sustained units. This allows them to be mounted anywhere, you could even just carry it around in your pocket if you want.
By eliminating the need for light switch wiring and having a central hub to control lighting of the entire home, one can program an endless combination of lighting scenarios, and change it without having to do any re-wiring. The energy saving opportunities are equally as enticing. A one switch shutoff for the entire house so you won’t have to worry about that closet light you forgot to turn off.
Verve Lighting Control Unit
The benefits of the system are endless. Not only does it greatly reduce lighting install time, labor, and cost due to the lack of a need for wiring switches, but the switches can be installed anywhere, and moved at any time. The system is completely programmable, so you can change the operation of each switch, or group lighting elements together. Imagine turning on one switch and having your entryway, driveway and garage lights all turn on at once, and then be able to click a button in your car to just turn on the driveway and garage lights only.
Solé Solar Roof Tiles by SRS Energy
Keeping in the solar powered theme of my last post, I wanted to focus a bit less on tongue-in-cheek novelty and hone in on some serious design.
Many architects, homeowners and commercial building owners out there aren’t very fond of the blocky look of solar panels, especially if their roof is highly visible or conforming to a specific style. For those who want renewable energy and beautiful design, SRS Energy has answered their wishes with their line of Solé solar roof tiles.
These solar tiles mimic the Spanish or Mission-style homes of California and Italian villas and have a curved surface and SRS Energy has partnered with US Tile to produce an easy to install standard size roof tile (which can be integrated with traditional clay tiles if desired). Instead of being the traditional orange/red colored clay tile, these solar tiles are made up of triple-junction amorphous solar cells produced by Uni-Solar. They are not quite as efficient as traditional crystalline silicon panels because of their curved shape semiconductor design, however, this is made up by the efficiency of the system.
Weekend Green Reads – Books on Sustainability
This weekend seems like a great weekend for reading, so I thought I would share some upcoming green books in my queue. I seem to have a sustainable design theme going, although that should come as no surprise to anyone who regularly reads my blog.
Sustainability in design has always interested me, mainly because so many problems with current products on the market can be solved by a tweak in the design. For many, this can entail looking at a product with a whole new perspective- which can prove difficult in many situations. Take for example one of the books, Design Is the Problem: The Future of Design Must be Sustainable.
The author, Nathan Shedroff, considers how paper bags may be worse than plastic for the environment or how a Prius may have a larger footprint than a H2 Hummer. Now these are pretty bold statements, so I am intrigued as to how he crafts his argument.
Another book along those same lines, Cradle to Cradle: Remaking the Way We Make Things by William McDonough and Michael Braungart, explores the cradle to cradle process (or C2C, the ‘birth’ of a product all the way through to the ‘death’ and re-birth of the raw materials) and how it can and should be implemented into the consumer stream.
This is a concept of growing interest (you can tell from increasing products advertising cradle to cradle certification), and with good reason. Our ‘disposable’ society needs a shift and the best way to do that is to make products with their ‘end-life’ in mind.
The two previous books are great reads for everybody, geared towards educating and inspiring with varying layers of depth. As an ecologist, my scientific background begs for more granular depth. At times, I like to see the data, the science behind things, the technical stuff. This is where Sustainable Design: The Science of Sustainability and Green Engineering
Providing “…readers with the scientific principles needed to guide their own sustainable design decisions”, and “written to enable readers to take a more scientific approach to sustainable design”, it will be sure to entice all you architects, engineers and scientific types.
