Dynamic Tower-Room with a Rotating View

Tuesday, November 25th, 2008

An apartment with a view is coveted property. After a hard day at work, sitting down in front of a panoramic window while sipping a glass of wine is a wonderful way to unwind.

A decent view is hard to come by. Not only that, but when actually given options, it may be hard to decide between the ocean view, city view, west side, or east side facing apartments. The answer: Individual rotating floors. Just make a choice and viola! The apartment slowly turns to face whatever you are in the mood to see that day.

Dubai, home to 1/3 of the world’s cranes, is constantly expanding. High rise buildings, hotels and skyscrapers are popping up like daisies. The latest technology and newest ideas are often used in the building process here, so it is no wonder that the revolutionary, rotating Dynamic Tower, designed by architect Dr. David Fisher, will break ground in Dubai.

The 420 meter (1,380) high tower will be constructed of 80 individual floors, which are divided into luxury apartments, small villas, offices and a hotel. Each section will rotate at various speeds, depending on the owners specifications. This amazing building will take on a life of its own as the individual sections slowly turn next to one another, constantly revolving and never looking exactly the same.

This skyscraper isn’t just going to look pretty, either: It is meant to generate electricity thanks to the wind turbines that will spin between each floor.

The construction technique is yet another feat in itself, making the complicated design amazingly quick to build. Fisher explains that the Dynamic Tower will be “the first skyscraper to be built entirely from prefabricated parts that are custom made in a workshop, resulting in fast construction and substantial cost savings. This approach, known as the Fisher Method, also requires far less workers on the construction site. [To put things into perspective, 2000 workers are typically needed on sites as big as this, but only 80 technicians are required for the tower].” In the end, it only takes 7 days to complete each floor!

Dynamic Tower should be opening its doors as soon as 2010.

TecEco - CO2 Absorbing Cement

Wednesday, August 6th, 2008

Cement is good for hiding whatever lies underneath. Old mob movies bring to mind laughing goons pouring the wet grey slurry over an unlucky victim, while rotting garbage is buried underground and sometimes paved over. Cement is not seen in a positive light, especially not when it comes to the environment.

The innovative mind of John Harrison thought up the idea of using waste (typically industrial and carbon) in cement, rather than simply producing cement to pave around it. Harrison, managing director at Australia’s TecEco, founded a company with the goal of producing a building material with a positive environmental impact.

Now a brand name, eco-cement is a limestone base (like all cements) mixed with magnesium oxide which is heated in a kiln and turned to powder. This powder will eventually be added to gravel and water to form cement. The magnesium oxide in eco-cement lowers the kiln temperature to about half of that required by the most common cement used in the world: Portland cement. This substantially lowers the amount of energy needed to make eco-cement. Not only that, but eco-cement is more porous than other cements and the unique magnesium oxide/cement mix actually absorbs carbon dioxide from the environment (only for about a year, though)!

In TecEco’s question and answers forum, the company was asked how they came about the idea of “eco-cement”. The answer was that “the idea of using carbon and wastes in building materials came from nature. During earth’s geological history large tonnages of carbon were put away as limestone and coal by the activity of plants and animals building homes such as the shells of shellfish and wood in trees. These same plants and animals wasted nothing as food and nutrients moved around and the waste from one was the food or home of another. John concluded that the answer to greenhouse gas and waste was to use them both in building materials.”

True to this ideal, eco-cement can be completely recycled when a structure is no longer required and reformed again.

As the founder and current chair of the Association for the Advancement of Sustainable Materials in Construction (AASMIC), Harrison is obviously devoted to green building materials. Online he writes; “I believe that our approach to sustainability must be holistic. i.e. a bit like dieting. The pain of either dieting or exercise is less if one does both. So it is with progress towards sustainability - reductions in energy usage as well as massive sequestration, less rubbish (e.g. packaging) as well as new uses for it are required. Improvements in energy use efficiency have been relatively popular as they save money. The harder task I am addressing is how to get the CO2 out of the air.”

The ideas presented by TecEco are catching on and other companies like Zeobond, scheduled to start operations in February, are adopting similar philosophies.

EnviroGLAS-Walking on Glass

Saturday, February 23rd, 2008

You look through it, drink out of it, watch television with its reflection-glass is everywhere. The uses are almost endless. Glass has existed since the beginning of time, where natural intense heat created by volcanic eruptions, meteors and lightning strikes transformed certain rock into this shiny smooth material. The earliest glass (non-translucent) dates back to around 3000BC. It is thought that Egyptians accidentally came across the craft when calciferous sand found its way into kilns and formed a glass glaze on the ceramics fired inside.

Glass was mainly used for decorative purposes at first, but it has come a long way since then. Every home and office is going to contain glass in one form or another - lamps, televisions and mirrors are all nonfunctional without the material. With so many items made from glass, however, it makes one wonder what happens to these things when they are no longer useful? 7% of household waste is glass and not all of it gets recycled. In 2001, over 2.5 million tonnes of glass was land-filled. This is unfortunate, as glass can be recycled indefinitely - its simple structure is not damaged when reprocessed.

Certain eco-friendly companies have invested in excess glass, taking advantage of its beauty and various functionalities. EnviroGLAS converts glass destined to be land-filled into gorgeous flooring, kitchen slabs and even incorporates the glass into landscapes.

“It was in 2002 that a glut of old glass bottles, mirrors and windows became the source for this chic green twist to the classic flooring concept. Publicity in July about the Texas city of Plano’s overabundance of crushed recycled glass inspired the creative solution of combining the multi-colored crystals with epoxy resin to create recycled glass Terrazzo.” (http://www.enviroglasproducts.com/about.asp)

Walking on floors designed by EnviroGLAS is a mesmerizing process, as bits of mirrors and colorful glass shimmer underneath your feet. There are dozens of colors to choose from and interested buyers can customize the mixture of glass to suit their taste. These color combinations are endless.

One concern is that these glass floors are fragile. This is definitely not the case. The website explains that “EnviroTRAZ recycled glass [and porcelain Terrazzo] will last the lifetime of your building, and most terrazzo floors last at least 40 years without needing refinishing. DFW Airport, Parkland Hospital, Dallas Baptist University and the City of Dallas’ Hensley Field Operations Center are four of the latest North Texas community landmarks to install this environmentally friendly flooring.”

Another benefit is that the seamless quality of the finished product is easy to keep clean. There are no nooks and crannies for mold or mildew to grow while the inert properties of the glass provide excellent air quality.

With maintenance costs almost nonexistent and endless pattern and color options - who wouldn’t want to walk on glass?
