General Description:
The Suzlon One Earth Corporate Headquarters project is an engineering marvel in all respects including excellent architectural design, and seamless integration with building services based on the essential green building concepts of energy efficiency and sustainability. This is a Zero Energy Project! Suzlon strives to demonstrate energy efficiency, sustainability as part of their work ethics. Suzlon is committed to generate Green power and create for its people a great place to work.
Suzlon Energy Limited is in the business of Green energy. It is one of the leading wind energy companies in the world. Standing for its motto ?powering a greener tomorrow?, the company was growing phenomenally and needed a Global Corporate Headquarters for its operations in the city of Pune, about 100 miles from Mumbai, India. The climate in Pune is dry and tropical with temperatures ranging from 25 to 40 degrees Celsius from winter to summer. This building is a new construction to house about 2300 inhabitants when finished. The built up area of the project is 816,171s.ft. The buildings are all Ground+2 levels except the Corporate House which is Ground+3. The project is in an urban setting spread over 10.4 acres. Suzlon One Earth has achieved Platinum level certification standards and over 154 KW produced on site with a total incremental cost of about 11%. There are no other LEED certified buildings with this level of certification and on-site renewable energy that have achieved this kind of cost efficiency. Recently, it has been awarded Teri GRIHA 5 star rating making it the largest and greenest building in the world under the new construction category under LEED certification.
Design and Innovation
The ?glass box? is entering the green context, totally inconsistent with the climate. From inception, this project attempts to take the other end of the sustainable rope and make a tug-of-war! From the initial design stage the architect and the client sought to make this a sustainable building complex.
A two week interactive ?design charrette,? engaging all of the specialized design teams, marked the beginning of the project, in which the context, site layout and generic forms of the buildings were addressed.
Key features were: a module small enough to allow natural light in (8.4 by 8.4 meters) and user visual access to the gardens, yet suitable for clustering in a ?flat slab? combination, allowing parking below; that all floors above ground level employ louvers to temper bright sun light, yet allow natural light; These flexible modules create a fabric that surrounds a large pedestrian garden, separating out all vehicles; high performance DGU (Double glazed units, KT 455 Toughened + 12mm air gap + 6mm clear toughened glass), pavilions and terraces are used on the ground level for garden connectivity. Glass chimneys were invented that open in the basement; heated air rises, sucking the basement air that enters through side sky-courts. These sky courts naturally light the basements.
