The idea of not harming the environment plus using the most ecologically friendly construction materials is becoming the norm for designers and builders around the world. Beautiful buildings that work with the environment are the heart and soul of ecoarchitecture Besides concentrating on using sustainable materials, eco architecture seeks to significantly reduce a building’s energy needs. The most Solar panel on a red roof eco-friendly buildings are designed and built with no need for external heating or cooling systems. When this level of zero demand isn’t practical, eco architects use building materials which capture heat during the winter and repel it in the summer. Energy consumption is slashed in addition to avoiding the expensive maintenance costs of elaborate environmental systems within the building itself. + Ecosystem is a community of living organisms (plants, animals) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting asa system. Sustainabilty '* Sustainability can be defined as the continued ability of a society , an ecosystem, or any such interactive system to function without exhausting key resources and without adversely affecting environment. \, pearate + Sustainable Design that meets the needs of the - present without compromising the ability of future generations to meet their own needs.

The endeavour is to seek minimum possible impact on environment. ‘The concept of Green Building concentrates mainly ontwo points: + Increasing the efficiency with which buildings use energy, water and materials + Reducing building impacts of human health and the environment, through better site selection, design, construction, operation, maintenance, and removal throughout the complete life cycle Why we need green buildings? We are loading our atmosphere with thousands of pounds of COs every year. To offset this CO: , more trees need to be planted. As per the estimates, in US only, to offset the huge amount of COs, trees need to be planted on 2.15 billion acres of land!!(The total land in USis 2.3 billion acres). According to US Green Building Council's study of Environmental impact of buildings (2007), Buildings in the United States contribute 38.9 percent of the nation’s total carbon dioxide emissions, (including 20.8 percent from the residential sector and 18.0 percent from the commercial sector), 39 percent of total energy use, 12 percent of the total water consumption, 71 percent of total electricity consumption. 85%, Le History of green building The increase of fuel costs in 1970's along with the concern for environment kindled the awareness and encouragement towards Green Buildings. Architects and ecologists started looking for solutions to achieve energy savings. But with the decrease of fuel prices, the Green movernent was slowed down and did not receive much encouragement. It was later in early 90's that the movement got kick start and awareness began to spread about need for sustainable buildings. An official Green home building program started in Austin, Texas in 1991. The movernent has gradually gained momentum since then and we can now find significant changesin the newer buildings.

The term "bioclimatic design" implies design which aims to protect the environment and natural resources. Aspects of bioclimaticdesign Green balconies The west side of a building can be made with small openings, be blind or be protected by appropriate shading (deciduous trees, awnings, plant hedges, etc.). The choice of plant species, the size at maturity, the way of pruning and the exact sitting of solar light trajectory is important for effective protection. Evergreen vegetation layout can be designed, with a preference for trees with dense foliage in combination with deciduous trees, in order todirect winter winds out of the building while achieving coolingin summer. Green roofs By implementing a green roof on the roof of a building reduces significantly the cost of heating the building, because the multi layered stratification reduces heat loss, depending on its thickness. Vegetation as well, acts as extra insulation depending on the coverage and density of foliage. Simultaneously reduces cooling costs by saving energy, as the temperature inside the building during the summer months, may be kept up to 10- 15 degrees below the outside. Note- The choice of bioclimatic design for the building and its surroundings can likely increase the total construction cost, but that can be depreciated by the limited use of units of conventional heating and airconditioning units. Furthermore, the indicators of fertility and living standards will be optimized. Vertical Gardens The term "vertical garden or green walls" means the planting on a vertical surface of a building, This is achieved by specialized systems and a particular variety of plants which are vertically attached to them, ‘The natural benefits of a Vertical Garden + Improved air quality + Lower energy consumption + Providing a natural shield between weather and inhabitants See rent Literature study eo iecagefariccrbntcnmetapsesene 1Conservation of fESOUrCes Landscaped sky gardens cct os buffers from the dust hed emare fh and lashing rain.

Rainwater collected from roof tops can be generally used as drinking water, for irrigation, landscaping, cleaning etc. Installation of water efficient or low flow equipments in kitchens and bathrooms to reduce water consumption. 1 ECO TOWER a/Content Tall building Introduction to tall buildings Today, itis virtually impossible to imagine a major city without tall buildings. Tall buildings are the most famous landmarks of cities, symbols of power, dominance of human ingenuity over natural world, confidence in technology and a mark of national pride.

A skyscraper can be distingue from tower .\ by its special emphasis on structure design to counter wind load prominent on height. Progtai Mix Use Tall buildings are designed primarily to provide the needs of the occupancy, whether single use or mixed-use, which include different types of functions such as commercial, business, hotel, residential, recreational, parking and like. That is, the “human centered design”, which means that the design should focus on people and be done for the people, is the keywordin the design of tall buildings. Lounge Plant Love!

These compressive and bending forces are carried down to the ground by the diagonal-braced frame (with added outrigger trusses). In addition to these components, a diagonal bracing filled with concrete, decreases the amount of steel required. Overall, the tower uses significantly less material than other comparable skyscrapers, such as the adjacent Jin Mao Tower.

These loads will be divided. Belt-truss Mega- diagonal Mega-structure ‘ Core Wall + Core wall has a size about 30 meters by 30 ‘meters and it reaches to the 79th floor of the building. + The core wall will be constructed with steel encased reinforced concrete. The tubestructure is connected with the core wall + There are two ways of ensuring the stability of the building, This system is called the dual lateral force system and ideal for tall buildings and is designed to be much safer and more robust during earthquakes and Core-truss ° Ye Outrigger-truss typhoons compared to a single lateral force system, which resists forces only with perimeter columnsand beams. The tubestructure is connected to the core wall with the outrigger trusses. Each outrigger truss is as high as three stories. At the first two levels where these outrigger trusses are applied, there are also the sky lobbies located. These levels are at the 28th, 29th floor and at the 52nd, 53rd floor of the building, approx58 m "approx 4m+ The reason why the core wall only reaches till the 79th level is because the hotel starts here. + The hotel needs another floor plan than the other functions that are located in the building. And it couldn’t use a core wall in its floor plan. + For this section of the building only the tubestructure takes care of the stabilityThe section above the hotelis the observatory. + The construction of the last three floors of the hotel, the penthouses, and the observatory is completely made out of steel, + These are in total 11 floors. The steel framework is only connected to the stable structure. The use of steel also works weight reducing and because of the fact that there are only a few more levels, there isn’t much pressure to resist by the construction. + The choice to make it out of steel is a logical one. Itis also easy to create the characteristic aperture in steel. If in another way constructed it would bea very difficult task. FOUNDATION + The foundation consisting of 2,200 piles at depths of 250 feet had already been laid in place. + In order to decrease the weight of the structure, LERA decreased the thickness of the concrete shear walls of the service core. + The Shanghai WFC was built on the deposited soil from the Yangtze River, which makes for poor engineering soil. The remedy for this was to deliver over 2,200 steel pipe pilings almost 80 meters below the soil, which supported a lattice shaped base to allow for some movement during an earthquake. Since this is a supertall building, the structural system was the main component to realizing KPF's design. 1. Foundation ples 2. Core wail 3.

Similarly, accidental removal can be accepted for the steel work within the services core. * Building Sway Reduced Through Vibration ControlTo improve residential comfort by preventing sway in strong wind, two mass dampers, each consisting of a 150-ton counterweight, are installed on the 90th floor to reduce building sway —EcoToweR COLUMN + The columns of the mega-structure are of mixed structural steel and reinforced concrete + At the connection of the mega-diagonals to the columns, the steel columns must be of a size capable of fully transferring the vertical component of the loadin the diagonalsto the composite columns. + Above and below this connection, the size of the steel column is reduced. Away from the area where the steel columns transfer loads to the surrounding concrete, the steel columns need only be strong enough to carry the construction load of the steelwork above and to meet specific requirements the building codes that govern and guide tall building design in China. + In the lower reaches of the building the composite columns are of impressive size.

This building has no defined roof, but the angled glass is the biggest factor in cooling the building. FIRE SAFETY + The core is a separate fire compartment with fire rated doors separating the core from the office space, to prevent smoke or fire from entering the core and travelling vertically up and down the elevator shafts. + All entry to the office elevators are through secure turn styles.
