Green Technology Centre displaying the latest and emerging green building materials and technologies in India Large numbers of visitors are escorted on green building tour
Ratings
Awarded the LEED Platinum Rating for New Construction (NC) v 2.0 by the U.S. Green Building Council (USGBC) in November 2003
Climate responsive design
Entrance
The main gate opens to a long driveway with lush greenery on both sides creating EMPHASIS to the entrance
The main building has direct access from the main road, But the entrance to it is from the inside to ensure privacy and security
30 % of employee transportation: carpools, bicycles, and LPG cars
Use of battery operated vehicles encouraged – Charging stations available
The documented reduction of harmful emissions achieved is 62 %
Encourage building occupants to minimize their reliance on fossil fuel-based transportation.
The traditional center courtyard with colonnaded corridors
The spatial and formal elements around a courtyard create introverted blueprint.
Courtyard space was not rigidly fixed but could be adaptable depending on the time of day, season
Its mood changed with varying degrees of light and shade, and with them the ambiance
Centrally located, serves as visual anchor. It was the spatial, social, and environment control center of the home.
By building them around a central open space ensured close relationships between separate units
Brought in an additional usable space within the living space.
Light and ventilation
Building layout ensures that 90 % of spaces have daylight access and views to the outside.
North facades are glazed for efficient diffused light
Low heat transmitting glass used
Double glass to further reduce heat gain
Natural lighting - no lights are used until late in the evening
Minimum lux levels for all work stations have been ensured
Light captured from as many sides possible - the use of courtyards
Jali wall
Allow controlled passage of air and light into the interior space.
throw patterns of light and shadow on the floor enhancing aesthetics
Ensure constant flow of breeze into the interior - occupant comfort cools the interiors
An alternative to costly window construction
Diffuse the glare of direct sunlight.
Energy efficiency
Use of Solar photovoltaic cells on the rooftop grid provides about 24 kilowatts, or 16 % of the building's electricity needs.
Placed appropriately on the roof facing South and West to capture maximum heat gain
Wind scoop
Energy savings are achieved by the GBCs two wind towers
Air, cooled by up to 8 ^C, is supplied to the AHUs, substantially reducing the load on the air conditioning system.
A heavily insulated roof further reduces the cooling load.
Earth sheltering
Earth sheltering is a an ancient architectural practice of using earth against building walls/ roofs for external thermal mass, to reduce heat loss, and to easily maintain a steady indoor air temperature.
Roof Gardens cover 55 % of the exposed roof area of the building – high reduction of heat gain
Water treatment
All wastewater generated - recycled by "root zone treatment" - simultaneously irrigates the vegetation.
Low operating cost, less energy requirement and ease of maintenance
Attractive alternative for wastewater management
Enhances the Landscape
CONCLUSION
The differences in green and normal building is that ―Green Buildings‖ are more environment friendly as they help in resources conservation .Also the initial cost may be higher but they prove to be economical in long run. Due to this advantage it is predicted that in 2 or 3 years there will be the 10% of the buildings will be green.
Green building – high performance building increases the efficiency with which buildings and their sites use and harvest energy, water, and materials.
Green building brings together a vast array of practices, techniques, and skills to reduce and ultimately eliminate the impacts of buildings on the environment and human health.
The `Green Building' concept is gaining importance in various countries, including India. These are buildings that ensure that waste is minimized at every stage during the construction and operation
Green building benefits
Increased occupant health and comfort as well as cost savings.
Reduction of VOCs that can off-gas from materials into the air we breathe.
Absenteeism and employee turnover dramatically decreases in several studies.
Reduced health care costs
Increased recruitment appeal to employees
Boost to reputation and public relations
Shortened project timeline,
Increased rents/asset values
Longer tenant tenure
Longer asset life
Increased business traffic and purchasing
Regulatory approval streamlining
Remaining competitive as product and service providers
