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.

The capital of England, the London is a global city and one of the largest financial centers is overflowing with the great skyscrapers. Being a city of tall buildings, London includes lots and lots of skyscrapers such as One Canada square, crystal palace transmitter, 8 Canada square, 25 Canada square, and BT tower and so on. Distinguishably, London is enclosing a very well known skyscraper namely 30 St Mary Axe. The specialty of this 30 St Mary Axe is it is standing not only as a great skyscraper but also as a London’s first environmentally sustainable building. Let us pass through the salient features of this eco-friendly building.
30 St Mary Axe
30 St Mary Axe is also known as “Gherkin” and “Swiss Re Building”, is a 40-storey building with a height of 180metres tall. The construction of this building ended on December 2003 and this building was inaugurated on April 2004. 30 St Mary Axe provides a flexible space and spectacular view of the city and beyond. It is the London’s first environmentally progressive working atmosphere that offers an extraordinary place to work. The design of this building was done by Lord Foster, Ken Shuttleworth and Arup engineers and it was constructed by Skanska.
This 30 St Mary Axe uses many energy conversation methods that allow it to consume half the amount of energy consumed by a conventional building. The exterior of this building is totally covered by 24,000 meter glass arranged in diamond shaped panes. This tower consists of 23 lifts and a ground elevator lobby with three gently curved walled lobes. This tower is aerodynamically designed so as reduce the wind load on the structure. The lower part of the tower tapers leading the wind to go round the tower and reduces the occurrence of downdraught on the surrounding plaza.
The façade of this building is fully glazed with double skinned glasses. This glass façade is cooled by the air extracted from the offices that results in reducing the overall heat load of the building. This façade is designed in such a manner that it can provide a safe and very easy access to all internal and external glazing and the cleaning surface.
Spiraling lightwells maximize natural ventilation whilst enabling the natural light to flood the interiors. This reduces the electric lightings, thus saving the electricity cost up to a notable extent. Windows of the lightwells open automatically, playing as a supplementary to the air conditioning system with the natural ventilation, which can save energy up to 40 percent per year.
The lightwells are glazed with openable double-glazed panels and a high performance coating which efficiently maximizes the solar ray penetrations. The highly decorative grey-tinted glass of the lightwells not only gives a gorgeous outlook but also reduces the solar gain to a maximum extent.
The office area incorporates the outer layer with double glazing and inner screen with single glazing. A ventilated cavity containing solar control blinds, sandwiched between the outer layer and the inner screen. This central ventilated cavity acts as a buffer which reduces the additional cooling and heating and gets ventilated by the exhaust air drawn from the offices in the building. This tower compromised many recycled and recyclable materials for its construction, wherever possible.
Gaps in each floor create six shafts which provide natural ventilation for the entire building. During summer, these shafts push out the warm air from the building and during the winter, it warms the building using passive solar heating. Shaft also allows the natural sunlight to penetrate inside the building, reducing the lighting cost.
By inhabiting various sustainable features as above this tower is sparkling as striking and eco-friendly skyscraper in the world. 30 St Mary Axe was honored with many awards. This tower earned the title of most admired new building in the world in December 2005, as per the survey of world’s largest firms of architects. In 2006, this building grabs the Civic Trust Award. On 21st Feb. 2007, IVG immobilien AG and UK investment firm Evans Randall completed their joint purchase of this building for GB£630 million.
