With more and more companies embracing green technology, construction companies have not been left behind in the move to creating new developments in the world of green technology. Green buildings look to reduce energy consumption and carbon footprint in the environment.
Buildings account for a large amount of land occupied, it is estimated that existing buildings are responsible for more than 40% of the world’s total primary energy consumption and for 24% of the global CO2 emissions. Green buildings bring together a vast array of practices, techniques and skills to reduce and hopefully eliminate the negative impact of buildings on the environment and ultimately human health.
From homes to skyscrapers, companies and individuals have seen the need to build structures that use up less electricity to heat, cool and light their homes and buildings by making use of natural means to do the above.
Green buildings often emphasizes taking advantage of renewable resources such use of sunlight through passive solar, active solar, and photovoltaic equipment, using plants and trees through green roofs, rain gardens, and reduction of rainwater run-off, using low-impact building materials and using packed gravel or permeable concrete instead of conventional concrete or asphalt to enhance replenishment of ground water among many others.
Green skyscrapers use thermoreflective filters which use nanotechnology to transition from a transparent to a reflective state in response to changes in the outside temperature. The transition allows a building to use the sun as a source of free heat on cold days and block solar heat effectively on hot days. This does effectively reduce the energy consumption of a huge building significantly.
Mick Pearce an architect in Zimbabwe, in collaboration with Arup engineers have studied the way a termite hill cools it’s nest and incorporated the design to their buildings. This has seen through the need to do away with conventional air-conditioning or heating to keep the green buildings cool or warm yet stays regulated year round with dramatically less energy consumption.
We have various other architects and countries working to build big green projects with the aim of reducing the carbon footprint. Just to mention a few, we have the Rotating Tower in Dubai designed by Dr. David Fischer on behalf of Dynamic Architecture, looks to stand at nearly 420 meters tall on completion and feature 80 rotating floors, 79 horizontal wind turbines (one between each floor), and photovoltaics on the rooftop, The World Trade Center Towers in Bahrain was designed by Atkins, it features three behemoth 96-foot wide wind turbine blades between the towers, over 1100 megawatts of electricity will be generated per year for the structure, The Pearl River Tower in China designed by Gordon Gill will have internal tunnels built into two of the building’s 71 stories, shaped like one giant wing that will serve to funnel wind into the tunnels, along with utilizing wind power, the tower will also integrate radiant slabs, geothermal heat-sinks, vented facades and integrated photovoltaics.
