Singapore’s Marina Bay Sands is a popular standout point for business and entertainment in Asia, that adds to its credibility by providing space for 2,560 hotel rooms, rooftop Sands SkyPark, convention and exhibition facilities, the best shopping mall in Asia, world-class celebrity chef restaurants, a casino, a Paiza Club for premium players, an outdoor event plaza and so on. What’s more, the new Eco-friendly development in this area – the ArtScience Museum – has tripled its attractiveness.
This ArtScience Museum, the first of its kind the world over, was inaugurated at Marina Bay Sands on February 17th, 2011. The shape of this ArtScience Museum is that of a bloomed lotus flower or a single palm with 10 fingers. This contemporarily designed Museum aims to become the heart of the growing art & science movement as well as the premier venue for international exhibits.
The Museum will display innovative and modern works in art and science on three floors of gallery space across over 4,800 square meters. There are 21 galleries in all. This project will attract not just tourists but also encourage cutting-edge practices as part of a new economy.
Museum – The Palm & its Energy-efficiency
Because of its palm-like appearance, the Museum is fondly known as “The Welcoming Hand of Singapore”. There are ten fingers on this palm, attached to a unique round base in the middle. The tallest “finger” stands 60 meters above ground. Each one of the ten fingers that extend out in the palm-like museum has a generous skylight that illuminates the interior walls with ample daylight.
Air conditioning grills built into the floor help save energy by cooling only the air up to the visitor’s height, rather than the entire space. Called air stratification, the technique is gaining popularity with engineering firms.
The ArtScience Museum incorporates several interesting features to make use of natural resources as efficiently as possible. The museum’s dish-like roof channels rainwater through the central atrium of the building, creating a 35-meter water drop into a 4,000 sq.m lily pond at the lowest level of the building. Rainwater is recycled and redirected through the water feature to create a continuous cylindrical waterfall. The rainwater is also recycled for use in the museum’s bathrooms as part of Singapore’s Green Mark program.
At night, the same dish transforms into an amphitheatre, enthralling audiences with awe-striking light and laser shows and fireworks with the city in the background.
Material such as Glass Fiber Reinforced Polymer (GFRP), typically used in high-performance racing yachts – which has never been used in a project in Singapore – has been used for the construction of this architectural wonder.
It is almost passé for architecture of all forms and for every purpose to take the Green route today. Be it educational institutions, corporate buildings, government offices or commercial buildings, public areas like airports, railways stations and sports stadiums, residential constructions or even hospitals – Sustainability and Green are buzzwords that none can ignore. But the winner is the “Golden Temple” of Sripuram in Tamil Nadu. As a place of worship, it stands out as the latest form of architecture, most unusually, that has embraced the Green concept.
This Golden Temple of Sripuram is a spiritual park situated at the foothills of Malaikodi, a village within the city of Vellore in Tamil Nadu, India. Sripuram received “Exnora Green Temple Award” and “Exnora Best Eco-friendly Campus of India Award” from Deputy Chief Minister of Tmail Nadu, Shri M.K. Stalin on 27th October earlier this year.
Exnora International is a non-government environmental service organization. The body has rated the temple as one of the best enviro-models of the world.
The temple is a paradise of sorts, where tranquillity, greenery and peace reign supreme. An attractive-looking terracotta-tiled ceiling over the 1.5 km long star-shaped foot path leading to the temple provides for the entry of ample natural light and wind.
The eco-friendly features include Solid Waste Management (SWM), Liquid Waste Management (LWM), rainwater harvesting, bio-gas generation, organic farming, herbal gardens, paddy fields and tree plantations, hill and campus afforestation and harnessing of solar energy. Manure and water for cultivation are generated internally.
Plastics and glasses are shredded, papers compressed into bales and sent for recycling by the Solid Waste Management system. Sripuram Temple attracts a daily footfall of over 5,000 which translate into two tonnes of waste, both bio-degradable and recyclable. The waste is either turned back into material or into manure which is used for the site’s soil. The waste water is recycled and used to irrigate the grass and plantations. Vegetables for meals are grown internally.
About 3 tonnes of cow dung aids in the generation of 50 kgs of fuel which in turn is used for cooking. Also, the bio-gas generated from a mixture of cow dung and waste food is used at temple’s accommodations, hospital and community kitchens.
Solar Water Heaters
Solar heaters generate hot water which is also used in the kitchens, thereby reducing the need for procurement of fuel from external sources by 80 percent. Canals and ponds dug up within the site help recharge ground water. The temple generates water for its own needs and also supplies some for public use when rainfall is insufficient.
Zero Waste Management (ZWM)
The temple also practices Zero Waste Management. This system includes a biogas plant. Between April 2002 and November 2003, the system has generated 33.8 tonnes of compost (worth Rs. 52,280) and earned Rs. 22,400 through sale of recyclables. The compost generated is used in various areas within the temple site like the gardens, agricultural fields, nurseries and for hill restoration. The success of the project has encouraged the management to extend the ZWM to the Malaikodi village.
Waste Processing Facility (WPF)
The temple authorities have set up a Waste Processing Facility (WPF). Four to five mega tonnes of garbage generated daily is processed by 70 workers. The bio – degradable waste is converted into organic manure through aerobic composting and vermicomposting. The recyclables are segregated into 48 categories, packed and sold to recyclers. The average income from sale of compost and recyclables is Rs.1 lakh per month. An average of 2 tonnes of garbage is collected everyday from surrounding areas.
During the treatment process, natural manure is created and used at the Sakthi Amma Greenery Afforestation Revolution (SAGAR) and the Sakthi Amma Afforestation Program (SAAP). Cleaning powders are made from fruit and vegetable peels.
Emerging or the budding buildings started to imbibe various energy efficient and green features in its construction, which will definitely be a cornerstone for its popularity and also a greatest measure to cut the cost incurred for the energy usage. Olive 8 building includes itself in the list of the green buildings by enclosing plenty of eco-friendly features.
This striking building has also officially earned the LEED silver Certification by the USGBC and moreover this the first time that the hotel/condominium building to receive the LEED silver certification. The olive 8 hotel is also one of the 20 green hotels in the U.S. Let us sail through the different construction features of this building.
Olive 8, fairly known as Hyatt at Olive 8 is located at Downtown Seattle, Seattle, Washington. The very luxuriate Olive 8 is a 39-storey building playing a dual role of hotel and condominium. Olive 8 contains 346 rooms in its first 17 floors and the rest of the 22 floors are occupied by 229 urban condos. This Olive 8 building was planned and designed by R.C. Hedreen Company. Mr. Hedreen aimed to make this building to achieve the LEED certification. Keeping this in mind, he redesigned the old plan of this Olive 8. At last he deserved it by giving a fabulous healthy and wealthy indoor environment to live and work.
The façade of the Olive 8 is a 100 percent glass exterior with blue architectural glass. The glass façade and the windows from floor to ceiling allow the abundant natural light to flood inside the building. Thus saving the energy used for artificial lightings. Triple-paned glass and a special coating on the exterior protect the excessive heating to the interiors.
The roof top of this building is one of the largest living rooftop in Seattle city. The roof is planted with native plant materials and traditional roofing material, is the greatest highlight. These plants on the roof reduce the amount of heating and cooling. The high island effect is reduced by a high performance ultra reflective surface membrane on the rooftop. It also decreases the amount of rain water flooding the storm sewers by absorbing and retaining the water in their roots and in the soil.
Olive 8 is expected to save 23 percent of energy more comparing to the other conventional building of similar size. All rooms of the Olive 8 are equipped with watt stopper ® technology that automatically turns the lights off when there is no foot prints. Olive 8 avoided volatile organic compounds by using low or no-VOC paints, solvents and carpeting. All the cleaning products are low-VOC and 100 percent toxic free. Washers, Dishwashers and refrigerators or Freezers are Energy Star® rated.
It also saves 36 percent of water, which is nearly equal to 2.4 gallon per year. It includes low-flowing plumbing fixtures, uses one gallon per minutes which is really less when compared to the traditional shower heads. Toilets and urinals use dual-flush system that saves 29 percent less water per flush. Additionally super efficient irrigation system tends the landscaping maintenance to use minimal city water and results in the 99 percent water savings, which is approximately equal to 24,000 gallons of water per year. A very low-chemical mechanical water system is used, which uses very less potable water.
Seattle Steam Company, which is providing the heating for the building, will reduce the carbon foot prints up to 50 percent by using biomass as fuel instead of natural gases. Olive 8 give more preference to the highly fuel-efficient vehicles in the parking area and outlets for electric cars in the underground parking area. Mostly, 95 percent of the construction debris is diverted from the landfills disposal by directing materials to be reused and recycled.
These above mentioned features led this building towards the LEED certification. The LEED silver certification signifies the building’s environmental leadership in the industry, both locally and nationally.
Airports are the very valuable asset of a country. Remarkably, Airports plays a very significant role in the country’s revenue.

Nowadays many nations in the world turned their attention towards the concept of green buildings, energy efficiency, sustainable and renewable resources. Many corporate organizations, government buildings and even the educational institutions started to take many steps to make the earth a greener place. On 29th July, 2009 – Among 20 finalists Corvallis high school in Corvallis, Oregon has earned the name “America’s most eco-friendly school” in the walmart’s “Earth Day Every Day School Challenge” after a very sticky competition.
Corvallis was one of the 20 finalist schools, nominated for the title of America’s most eco-friendly school. These 2o finalist schools were selected by three independent judges. They analyzed totally 439 qualified essays, which describes the efforts taken by the schools to make the earth greener by supporting the energy efficiency to select those 20 finalists. Then the entire 20 finalist submitted a short video, to present their environmental activities that they described in their essays. All those essays and the video presentations were posted at the website namely http://www.earthdayeverydaychallenge.com from June 9th to June 19th.
Americans were requested to pool their votes for the school that they believed should be awarded the title as well as the $20,000 grand cash prize. Tremendously, during those ten days of voting period, more than 22,000 votes were cast. Five schools who occupied the first five places by the vote ratings are Corvallis high school (Corvallis, Oregon), East Burke high school (Connelly springs, N.C.), Maple Avenue elementary school (Claremont, N.H.), Beverly Elementary school (Beverly Hills, Mich.) and Old trail school (Bath, Ohio).
In those five schools, Corvallis high school who had received the large number of votes was awarded the great title of America’s most eco friendly school with the cash prize. The officials of the Corvallis high school said that their school consumes 30 percent less energy when comparing to the other schools built in Oregon code. And they said that they are going to install the solar panel on the roof of the buildings. Officials hope that this installation will definitely reduce the consumption further.
Recycling is essay accessible throughout the school and it is managed by the leadership class. Additionally, a group of students are working to pair recycle bins with garbage cans in the Corvallis downtown area. The school is certified with the LEED silver rating.
This year, a group of students traveled to the national power shift environmental conference in Washington D.C. Students are also working with the Oregon state university to organize various environmental camps to create the knowledge about the green buildings. This school also offers environmentally focused classes, which includes Economics of Conscious Consumption, AP Biology with a bio-diesel capstone project, Political Actions Workshop and AP Environmental Science.
The green club of the schools organizes a campaign to create awareness about the effects of enormous amount of carbon emission and to encourage the students to use carbon-neutral transportation by offering incentives to bike or walk to school. These are the few reasons for what this school was chosen for this grand title and for the grand prize of $20,000. This cash amount was provided by Walmart for the future environmental efforts of the school. A teacher who entered into the challenge on behalf of the Corvallis high school said that the award of $20,000 is a huge affirmation to the students, staffs and to the Corvallis community.
Walmart also recognized all other finalist schools by awarding a cash prize of $500 for each school. This can be used to buy the items that will helps to enhance the environmental friendly and energy efficient activities.
