Renewable Energy

  1. 1. RENEWABLE ENERGY The key to sustainable development is basically maintaining an appropriate balance between development and conservation. In fact, environmental management is essentially managing human activities so as to minimize adverse impacts on the environment. Sustainable Construction Management
  2. 2. New Record: Wind Powers 40% Of Spain Wind Powers Idea Of Renewable Technology Wind power is breaking new records in Spain, accounting for just over 40 percent of all electricity consumed during a brief period last weekend. As heavy winds lashed Spain on Saturday evening wind parks generated 9,862 megawatts of power which translated to 40.8 percent of total consumption. Between Friday and Sunday wind power accounted for an average of 28 percent of all electricity demand in Spain. Spain’s wind power generation equaled that of hydropower for the first time in 2007. Spain, which along with Germany and Denmark, is among the three biggest producers of wind power in the 27-nation European Union, is aiming to triple the amount of energy it derives from renewable sources by 2020.
  3. 3. North America’s Largest Solar-Electric Plant The plant, which cost $100 million to construct covers 140 acres of land Solar Powers North America’s largest solar photovoltaic system is now running and generating power — about 30 million kilowatt-hours of electricity annually. The 14 megawatt power plant is at the Nellis Air Force Base in the sunny desert of southern Nevada. It’s expected to save about $1 million in power costs annually, and reduce carbon dioxide emissions by 24,000 tons each year. The photovoltaic system is made up of 72,000 solar panels. It’s enough to provide 30% of the electric needs on the base, where 12,000 people work and 7,215 people live. But at 14 megawatts the power output of this system is modest, compared to the solar thermal Nevada One project which generates 64 megawatts of power. Idea Of Renewable Technology
  4. 4. 11 MW Solar Tower Complex Opens in Spain The tower project is called “PS10″ and it uses 624 large movable mirrors called heliostats. Each of the mirrors has a surface measuring 1,290 square feet that concentrates the Sun’s rays to the top of a 377 foot high tower where a solar receiver and a steam turbine are located. The turbine drives a generator, producing electricity. PS10 is the first of a set of solar electric power generation plants to be constructed in the same area that will total more than 300 MW by 2013. Power generation will be accomplished using a variety of technologies. Europe’s first concentrated tower open recently near the sunny southern Spanish city of Seville. The 11 megawatt plant took four years to build — it was created by a Spanish energy company, Solucar. Idea Of Renewable Technology

  6. 6. Madrid Spain Huge “Air Tree” Structure Produces Its Own Power and Oxygen In Madrid, Spain they are currently building a huge structure called an “Air Tree” or “Eco Boulevard de Vallecas”. The Tree was created by Urban Ecosystem to be a social center, and to improve the surrounding environment. The structure is also completely self-sufficient, generating all its own power with solar cells. Any surplus energy is sold to the electrical grid. It also produces oxygen using its arrays of plants and trees, hence the “tree” appellation. Idea Of Renewable Technology

  9. 9. Innovative Tower To Feature Atrium Of Wind Turbines Building on principles of biomimicry, Clean Technology Tower utilizes advanced technologies and climate-appropriate building systems to foster a symbiotic relationship with its local environment. The tower is sited and formed to harness the power of natural forces at its site- but it refines the conventional methods of capturing those natural forces to significantly increase efficiency. Wind turbines are located at the building’s corners to capture wind at its highest velocity as it accelerates around the tower. Idea Of Renewable Technology
  10. 10. The Devonshire Building was designed by the Dewjoc architecture firm. It is home to the Institute for Research and Sustainability at the University of Newcastle. The Devonshire Building - Sustainable solar shading for science structure. The Devonshire Building is a landmark six-storey edifice in the heart of University of Newcastle’s campus and is due to become operational in April 2004. It is home to the Institute for Research and Sustainability and the Regional E-Science Centre and is therefore a pioneering construction embracing recycled materials, renewable energy and solar power, reflecting the University’s commitment to the environment. The Devonshire Building – Sustainable Solar Shading Idea Of Renewable Technology
  11. 11. The building’s large roof area also allowed the construction of a rainwater harvest system. The rain is collected via a symphonic rainwater system and then fed into a 20,000 liter underground tank. If the rainwater tank overfills, it overflows to a 40,000 liter geothermal tank to replenish the water for a heat sink that acts as a cooling source for the building and services’ systems.

  12. 12. A fluid aesthetic façade solution Steve Halsall, project architect with The Dewjoc Partnership comments: “The prime objective to the building design was the integration of the solar shading with the façade design. Levolux took up the challenge by taking on a proactive role in the design development of the solar shading system, which has resulted in a fluid aesthetic façade solution.” The Devonshire Building – Sustainable Solar Shading Idea Of Renewable Technology
  13. 13. Stunning Solar Building Will Generate More Power Than It Needs The Masdar Headquarters Building Construction of Masdar City commenced with a formal ground-breaking ceremony on February 9, 2008. The City will be constructed over seven phases and is due to be completed by 2016. Masdar’s headquarters is part of phase one and were completed end of 2010. Masdar Headquarters will have the lowest energy consumption per square foot, it will feature the largest photovoltaic system and the largest solar thermal driven cooling and dehumidification system. The building will also have integrated wind turbines. It will consume about 70% less water than a typical mixed-use building of its size. Idea Of Renewable Technology

  17. 17. Here’s an example of day lighting at the Hong Kong Science Park. Notice that the light is filtered through translucent skylights and clerestories in a central atrium, thus reducing glare and overheating. The top of the building has shades, see them after the jump:Sunshades are extensively incorporated into the external facades to shield direct sunlight penetration, reducing heat gain to the office so as to reduce electricity consumption for air conditioning Hong Kong Science Park – Solar Glass Idea Of Renewable Technology
  18. 18. Hong Kong Science Park – Solar Glass BIPV panels have been fitted to the facade, the louvers and the roof canopy of the Buildings in Phase 1. The BIPV is connected to the electricity grid and have an approximately 200 kilo-Watt output. The installation of BIPV panels can pursue new clean energy technologies, reduce consumption of natural resources and cut emissions to the atmosphere. It can save approximately 250MWh of electricity consumption annually. Idea Of Renewable Technology
  19. 19. German Parliament – 100% Renewable Power The German Reichstag is expected to become the greenest parliament building in the world, thanks to a decision to rely solely on renewable energy. From late summer the building is due to swap to green power sources such as water, wind and solar energy, replacing the conventional power that it has largely relied upon until now. Its extensive refurbishment in the late 1990s, including the glass cupola designed by the British architect Sir Norman Foster, had already won it plaudits. Ecologists praised the building’s energy efficiency, which has led to a 94% cut in its carbon emissions. Its roof makes passive use of solar power and natural light and its thick, well-insulated 19th-century walls help retain warmth in winter and reduce the need for air conditioning in summer. At the moment biofuel generators in the basement produce 40% of the building’s energy, for lighting, heating, the flow of air conditioning and water, while the rest comes mainly from coal and nuclear supplies.

  20. 20. Green Towers In Malaysia Modeled After Fleet of Ships Sustainable Tower in Malaysia These unusual, onion-shaped towers are designed for Precinct 4, or the Putrajaya waterfront in Malaysia (30 kilometers south of Kuala Kumpur). Designed by Studio Nicoletti Associati, was inspired by ship sails and traditional Islamic architecture. The architect’s goal was to design buildings that tell “of its place of origin which is culturally modern, Islamic and tropical in nature.” Added to this is Nicoletti’s extensive experience in design and construction for extreme climates. The Italian firm brought sustainable strategies like terraces, sunshades, natural ventilation and integrated green space into the design. The buildings will source from alternative energy and are expected to produce 50% less CO2 emissions than similar residential projects. Idea Of Renewable Technology
