‘Suzlon One earth’ is a sustainable corporate campus spreading over a site area of 10.5 acres in Pune. A ground to earth structure complementing nature alongside its planning. Meanwhile, using the philosophy of ‘powering a green tomorrow’, the vision of designing was a place with village characteristics, with nature influence use of natural light and ventilation. Also, use of technical facilities that bound neighborhoods. Suzlon One Earth is also India’s largest producer of clean wind energy.
- Name: Suzlon One Earth
- Architect: Prof. Christopher Benninger
- Location: Pune
- Year: 2009
- The different aspects that were took into considerations were:
- Designing based on Vaastu shastras.
- A traditional system based on directional alignments.
- Water efficiency measure
- maximum use of natural resources.
- Zero waste policy on campus Decrease environmental impact.
- Uses of green energy and sustainable building practices.
The aim of the campus was not only to build a corporate office but to set an example of how a company functions in a sustainable environment. It is an inspiration to others. The development at cost of the environment is hazardous and the concept of sustainability needs to be implemented. An increase in population and climate change has led to an increase in natural calamities and unpredictable climate change. And made havoc with food production, with major environmental threats as land degradation, deforestation, land, water, and air pollution have become major concerns.
Need for sustainability
As the increase in humankind across the world has increased, the balance of humankind in comparison to natural resources needs to be maintained necessarily. With a constantly changing world over the last couple of centuries, we had a tremendous change in environment and climate, but not every change is beneficial. The development at cost of the environment is hazardous and the concept of sustainability needs to be implemented. An increase in population and climate change has led to an increase in natural calamities and unpredictable climate change and made havoc with food production, with major environmental threats as land degradation, deforestation, land, water, and air pollution have become major concerns.
Site selection and considerations
The site selection was such that construction should have the lowest impact on the environment. However, the selected site fulfilled all the physical requirements with basic services as banks, convenience grocery, cleaners, fire station, medical facility, pharmacy, etc.
- The surrounding context:
- residential development with minimum density in the Hadapsar area opposite Magarpatta city,
- corporate offices and
- residential areas.
The entire design process was to create indoor and outdoor spaces in a manner that would increase sustainability.
- The major elements considered are:
- Preservation and protection of landscape during construction.
- Ensure soil conservation Include existing site features.
- Reduce hard paving on site.
- Enhance outdoor lighting system.
While designing such a sustainable campus many elements from traditional building techniques, such as horizontal louvers, roofing design, energy saving materials in interiors,recycled materials, sewage treatment plant and integrated building management system (IBMS)and use of electric vehicles within campus.
Designing a campus with sustainable features not only reduce environmental impact but also added benefits. However, these benefits are reducing operational cost, maximizing energy, water saving, and reducing indoor air quality problems.

Energy conservation in campus
One of the main indicators is environmental sustainability. It requires the use of natural resources such as energy and water by humankind, at the rate at which it can be recycled and reused. It implies a reduction of wastage at every level. Renewable energy sources like windmills and solar panels with a capacity of 154kw on-site fulfill the requirement of 5% energy on the campus. Beginning with the baseline, energy efficiency, conservative use of energy, and every production from renewable sources was the optimum focus. In short, the integrated energy conservations on-site are wind-solar hybrid system power generation, e-vehicle charging facility, and solar heating system.
Shading and lighting methods
The site includes energy conservation methods which included high-performance glazing, use of shading, HVAC system, overhangs, efficient lightning designs, direct-indirect evaporative cooling, jet fans for parking ventilation, etc.
Firstly, Shading and overhangs-Ground floor glade is mostly shaded by the extension of terraces and pavilions on the first floor. The overhangs on the third floor provide the most effective shading and external louvers on each level give 100% shading.
Secondly, Effective lightning– One efficient way to save light is to make maximum use of daylight. Inside cutouts on the external periphery and a large one at the center of the building. Which helps in the quality of light throughout the basement. The lighting system includes occupancy sensors, motion sensors, and daylight sensors, which ensures that lights are on only when required. The artificial lights are adjustable ranging from 0-100% according to the available daylight.
Thirdly, The HVAC system– The indoor cooling system helps every individual to control the temperature according to their preference. The different types of space conditioning ways used are pre-cooling and heat recovery at treated fresh air, direct-indirect evaporative cooling, and jet fans for parking facilities.
Firstly, the water management plan included measures like rainwater harvesting, water recycling, and gray water recycling to ensure the use of 40% less potable water. Secondly, Recycles gray water for flushing, irrigation, and HVAC are the main measures of energy conservation and water efficiency. Thirdly, the concept of pebble drain is used for the surrounding landscape, where all the excess water from the hard surface is drained onto a pebble drain. Meanwhile, rainwater treatment plants and sewage treatment plants have been installed. Moreover, the landscape design consists of native or naturalized species of plants whose water consumption and maintenance are low.

Rainwater and recycled water have been used in air conditioning units which reduces the usage of water by 50%. The wastewater generated in the kitchen, toilets, and washing area is treated in the Sewage treatment plant to tertiary standards. Strom water generated is used in landscape irrigation, toilet, and flushing. A rainwater harvesting tank has been used for channelizing rainwater run-off.
The main aim of waste management is not only to reduce the wastage of scarce resources but reuse and recycling of materials. Which helps down in negative effects of waste management. A huge amount of waste is generated during construction, reducing this is a priority concern for any sustainable campus. Efforts to recycle materials like cardboard, metal, brick, acoustical tile, concrete, plastic, clean wood, glass, gypsum wallboard, carpet, and insulation. Zero waste policy formulated to create awareness among people to make responsible use of resources such as paper, cardboard, food, etc.
Material and resources
The use of environment-friendly material from renewable resources, which are more suitable for a project in a particular environment. One Earth had three main parameters for the selection of materials they were: firstly recycled, secondly regional, and thirdly rapidly renewable. They used materials with higher recycled content. Many interior finishes such as ceilings and glass partitions were composed of recycled materials. The recycled content material should meet the environmental, economic, and performance attributes. Architect Christopher Charles Benninger used local material that is available within a radius of 800km.
Thus, increasing demand for building materials and products and thereby supporting the regional economy and reducing transportation costs. Meanwhile, The main aim was to reduce the use and depletion of finite raw and long recycle renewable materials by replacing them with rapidly renewable materials. Materials such as bamboo, wool, cotton, insulation, agrifiber, linoleum, wheat board, strawboard, and cork were used for flooring, skirting, ceiling, tiles, walls or partitions, etc.
Moreover, the Suzlon One Earth campus uses less energy, creates minimal waste, less use of water and natural resources and the surrounding environment is quite healthier for the users compound to standard conventional buildings. One earth project has been a complete wonder with all the aspects considering the users, their working function, the need for workspace, and comfortable surroundings. It has used optimum aspects of sustainability and design. In conclusion, We wish such projects inspire architects and the damage to the environment can be restored.
