Curving Wood Floors Make Less Waste


Wood floors aren't normally what you would think of as high tech. But a Dutch company called Bolefloor is using computers and viagra using CNC production to produce attractive and distinctive wood flooring that maximizes the amount of wood used. By scanning the wood and then using computer algorithms to calculate how best to cut the wood, unique floors with curving patterns can be produced that fits together like a jigsaw puzzle and minimizes waste.

According to the company, the technology used in this process maximizes the yield of usable wood flooring by using "wood scanning systems, tailor-made CAD/CAM developments and innovative optimization algorithms for placement software developed by a Finnish engineering automation company and three software companies in cooperation with the tramadol 50mg tablet Institute of Cybernetics at Tallinn University of Technology." In addition to determining how to fit together the pieces of wood, the software also takes into account imperfections in the wood near edges or ends, so that the floor will be more durable.

I'm not completely sold on the idea that this is leads to a significant savings of wood. But, for the wood that is viagra from canada used, this aproach should allow some further use of click here discount cialis cialis material from each log and the ability to use smaller logs, as well.

Each floor needs to be custom produced using this system, which limits its applicability for off the shelf projects. But, if the need for a repair arises, the fabrication of a replacement piece should be easy to accomplish, using the same file that was used to create the original piece to fabricate a copy.

If you are interested in maximizing production volume, this certainly wouldn't be the way to go. Efficiency is all about straight and discount online levitra regular. But if your definition of sustainability means 'taking care of what you have,' then creating something unique and beautiful that will encourage its owners to care for it and maintain it so it lasts, then this is a wonderful sustainable material.

New Tower Will Have Blimps on the Sides


The skyline of Taechung, the third largest city in Taiwan, will never be the same after the winner of the ordering cialis gel Taiwan Tower Conceptual International Competition was recently announced. The 390 meter (1,280 foot) tower looks like a docking station for airships with a number of large inflated elements on its sides. Designed by Romanian architect Dorin Stefan, the prizewinning scheme is slated to begin construction in 2012.

The plan is certainly audacious. The airships are helium-filled observatory "leaves" covered with PTFE (the same lightweight, transparent construction used for the famous "Water Cube" from the 2008 Beijing Olympics) which can carry as many as 72 people up and down the sides of buy ultram uk the tower. The rest of the building features many other green and high-tech elements, including geothermal heating and water heating in the basement, natural ventilation through the "chimney" effect, solar cells and axially mounted wind turbines around the building's core for power, fiber optic lighting for its basements, and a rainwater collection and viagra online without prescription purification system.

New York's Largest Green Roof Has Major Impact

New York City's largest green roof sits atop the U.S. Postal Service's Morgan Processing and Distribution facility in midtown Manhattan.  On this roof resides 2.5 acres of dense vegetation that two years after its installation have made a major impact on the building and the city.

The green roof, which is one of the largest in the country, was completed in December 2008 and since then has really become living proof of the power of green roofs.  The roof has has reduced the building's storm water runoff by 75 percent in the summer and 40 percent in the winter.  The U.S. Postal Service says the roof's ability to cool the generic pack cialis building in the summer and insulate it in the winter saves about $30,000 a year in energy costs.

While green roofs are more expensive than traditional roofs initially, they last 50 years -- more than twice as long as a traditional roof and they quickly lead to savings in storm water management, heating and cooling, cleaning the air and costs related to the urban heat island effect.

Toronto, the first city to lowest price on levitra mandate green roofs on new construction just this past year, has conducted studies that concluded that if 75 percent of the city's roofs were greened, the city would save $37 million a year.  Urban heat island effects could be reduced by as much as 2 degrees Celsius.  You can read more about the Toronto bylaw here.

Green Residential Products Showcased at Greenbuild


This year's 2010 Greenbuild Conference and Expo offered the usual enormous hall filled with displays of best price for generic levitra all kinds of products and building materials that can be used to create greener buildings.

Eco Home Magazine has a slideshow of 14 of the products that were on display at this year's Greenbuild. These are more residentially-oriented products, compared to the rather many more products aimed more at the commercial building market.

Some are fairly prosaic, and will still be chiefly of interest to builders and professionals (unless you happen to be a fan of drywall or plumbing fixtures), but others are more interesting, like a Freewatt Plus microCHP unit (PDF) that is available both for forced air as well as hydronic installations in homes, although EcoGeek readers have known about microCHP plants for years.

Another new item is the Modlet, a web-addressable module that plugs into a conventional outlet and then allows you to monitor and control energy use through a browser. This should be reaching the market in the coming year with both online sales as well as retail.

Of course, it should still be noted that making a greener building is far more than just buying a few green products. The basic operation of a building can be enhanced by added green hardware, but a bad design can't be redeemed simply by including a few green elements. Fundamentals of good green design are still the just try! buy cialis us most important part of buy viagra from britain creating an environmentally appropriate building.

Astounding Phase-Change Windows


A remarkable new glazing system has been available in Europe for several years and is now being brought to the North American market. The GlassX window is an insulated glass assembly that incorporates a phase-change material (PCM) between two of the glass panes in the window. At lower temperatures, the PCM is a translucent solid. But, as it heats, the PCM melts and becomes transparent. This lets the window itself absorb heat from solar energy during the day, and then releases the energy again later on, as the material cools again.

The combination of good insulating windows along with heat storage makes these windows very useful for passively designed buildings. PCMs are excellent heat storage materials, and the GlassX windows are able to store as much heat as a 9" thick concrete wall. Even in its solid, translucent state, the GlassX windows allow more than 25% of the exterior light through, so that daylighting is not entirely lost. The windows also incorporate a diffuser that reflects high angle light from the sun in summertime, while allowing low angle light in the winter to viagra in mexico pass through more directly.

These are not ready replacements for the current windows in most homes. The GlassX windows are over 3 inches (8 cm) thick and weigh nearly 20 pounds per square foot (100 kg/m2). They are also rather expensive at $60-90 per square foot ($560-$970/m2), but the company expects payback on these to be under ten years. There are several installations of the material in Europe, but as yet there are none in North America.
