Shanghai Tower, Shanghai, China, 2008-2014

• 632 metres (2,073 ft), have 128 stories, and contain an area of 380,000 m2.

• It is the tallest building in China and is slated to be the second tallest in the world.

• Tower features office space, luxury residences, a high-end hotel, retail space, restaurants and a public observatory.

GREEN STRATEGIES

• SUSTAINABLE DESIGN IS AT THE CORE OF SHANGHAI TOWER’S DEVEOPEMENT. TO ACHIEVE THE LEED GOLD AND CHINA THREE STAR RATINGS.

• A FULL 33 % OF THE SITE IS GREEN SPACE, WITH LANDSCAPING THAT BREATHES FRESH AIR INTO THE CITY AND SHADES PAVED AREAS THAT RADIATE HEAT.

• STRATEGIES ARE AS FOLLOWS

1. DAY LIGHTING.

2. SUN SHADING

3. BUILDING CONTROLS

4. COGENERATION SYSTEM

5. REGIONAL MATERIALS

6. LANDSCAPING

7. WIND TURBINES

SUN SHADING

• TO REDDUCE HEATING AND COOLING LOADS BOTH THE INNER AND OUTER CURTAIN WALLS WILL HAVE A SPECTRALLY SELECTIVE LOW E COATING ,FRITTED GLASS ON THE OUTER WALL PROVIDES ADDITIONAL SUN SHADING.

BUILDING CONTROLS• SHANGHAITOWER

INCORPORATED INTELLIGENT BUILDING CONTROLS THAT LOWER ENERGY COSTS BY MONITORING AND ADJUSTING SYSTEMS SUCH AS LIGHTING, HEATING,COOLING , VENTULATION AND SELF GENERATED POWER

COGENERATION SYSTEM

• THE 2200-KW NATURAL GAS FIRED COGENERATION SYSTEM PROVIDES ELECTRICITY AND HEAT ENERGY TO THE LOW ZONE AREAS. IN ADDITON TO PROVIDING SITE GENERATED POWER THE SYSTEM PRODUCES 640 TONS OF REFRIGERATION .

DAY LIGHTING

• THE CONTINOUS GLASS SKIN ADMITS THE MAXIMUM AMOUNT OF DAYLIGHT INTO ATRIUMS, REDUCING THE NEED FOR ARTIFICIAL LIGHTING.

RESGIONAL MATERIALS

• THE TEAM SEEKS OUT BUILDING MATERIALS THAT ARE HARVESTED AND MANUFACTURED WITHIN AN 800 KILOMETER RADIUS OF THE SITE. LOCAL SOURCING OF PRODUCTS IS SUSTAINABLE BECAUSE IT REDUCES TRANSPORATION RELATED ENVIRONMENTAL IMPACTS.

(Gensler)Tower features a soft triangular shape, the tower rotates as it goes skyward and concludes with an open-top design.

As the shape rises, a "strike" or open notch curves up and around the building which is an engineering feature to control the wind up and away from the building.

second skin

Uses 32 – 35% less structural materials ( concrete and steel ) than any other conventional buildings. It results in savings of 58million US$

With the double skin , the building will function like a thermos bottle. This allows it to

• harvest and use daylight,

• reduce artificial lighting to a minimum,

• increase the insulation of the building's interior

• reduce energy consumption and energy costs.“

Double skin Building

The development will be separated into eight distinct bioclimatic zones, with each having its own atrium, lush gardens, indoor air controls and panoramic 360° views of city.

The building will be situated within a 10,000 sqm open green space that will become both a public park and the front entry to the tower.

Sustainability

• Innovative skin technology is one of many sustainable design and renewable energy systems in the tower.

• The spiral shape facilitates vortex shedding and creates an asymmetrical surface to reduce wind loads on the building by 24%. reducing the structural load on the building.

• The building’s spiraling parapet collects rainwater, used for the tower’s HVAC systems.

• Wind turbines located directly beneath the parapet generate on-site power. Thus energy consumption of building is 35-40 % less than any other conventional building.

• 40% less water consumption i.e. they save 675 million L/ annum = 245 Olympic size swimming pools
