History

In 1995, founder
Tulsi Tanti Tulsi Tanti (2 February 1958 – 1 October 2022) was an Indian businessman best known for being the founder and chairman-cum-managing director of Suzlon Suzlon Energy Limited (NSE:SUZLONEQ, BSE:532667) is an Indian multinational wind turbine ...
was managing a 20-employee textile company. Due to the erratic availability of power locally, and its rising costs, the highest business expenditure after the raw materials was electricity. The cost of electricity also offset any profits made by the company. After providing electricity for his own company, Tanti moved into wind energy production as a way to secure the textile company's energy needs, and founded Suzlon Energy. Suzlon adopted a business model wherein clients would be responsible for 25% of the up-front capital investment and Suzlon would arrange the remaining 75% on loan. Initially, banks were hesitant to fund loans for this model, but by 2008, many Indian banks started financing wind power projects for Suzlon clients. In 2001, Tanti sold off the textile business; Suzlon was still actively run by Tulsi Tanti, now in the role of Chairman, Suzlon Group. In 2003, Suzlon got its first order in USA from DanMar & Associates to supply 24 turbines in southwestern

In June 2007, Suzlon had signed a contract with Edison Mission Energy (EME) of US for delivery of 150 wind turbines of 2.1 megawatts in 2008 and a similar volume to be delivered in 2009. EME had an option not to purchase the 150 turbines due to be delivered in 2009, which it has chosen to exercise. In November 2009, the company decided to sell 35% stake of Hansen for $370 million as part of its debt restructuring program, through placing new shares. It appointed Bank of America Merrill Lynch and Morgan Stanley as the managers and book runners for the same. In January 2011, Suzlon received an order worth US$1.28 billion for building 1000 megawatts of wind energy projects from the Indian branch of the Lord Swaraj Paul-owned Caparo Energy Ltd.

development. Suzlon's corporate headquarters are located at One Earth - Pune, one of the greenest corporate campuses in the world and a Platinum LEED accredited and GRIHA 5 star site. The campus was opened in 2009. One of the most well-known companies in the world in the field of renewable energy, The Suzlon Group has pioneered the use of sustainable energy sources. They wanted their new headquarters to reflect their belief that a physical workplace should blend into the natural environment. Famous Indian historical landmarks like Fatehpur Sikri and the Meenakshi Sundareshvara Temple Complex in Madurai were significant design inspirations for Suzlon One Earth. On these campuses, open and enclosed spaces are cleverly mixed in a clustered design. Both contain flat, sturdy elements connecting the complexes and draw attention to elements emphasizing sacred sites and quadrants. The concept of having water bodies on these reference campuses was carried over to Suzlon One Earth. The building is constructed by one of India's highly decorated architects Prof. Christopher Benninger who has won the Indian Institute of Architects’ Annual Award for Excellence six times, more than any other architect.


Project information

Address: Pune, Maharashtra, India Rating system: LEED BD+C: New Constructionv3 - LEED 2009 Last certified on: March 1, 2010 Certification level: Platinum Suzlon One Earth, a project that has established numerous precedents concerning energy efficiency, water management, harvesting, and waste treatment systems for developing countries, has propelled India onto the international green map. Suzlon Energy Limited promised to build India's greenest office. The three-story structure is situated on 10.5 acres. Wind turbines (80%) and conventional and building-integrated

s (20%) are used to produce 5% (154 kilowatts) of the energy used there each year. One Earth is a zero-energy project because Suzlon's off-site wind turbines produce all the balance energy needed for the campus. 90% of the workstations have daylight and exterior views thanks to the design, which takes cues from vernacular architecture while preserving the environment and culture. This allows people to take in the seasons and weather and feel connected to the time of day. Light and cross-ventilation are permitted through aluminum louvers, which serve as a protective skin.

Site and Site Context

The benefits of a developed area were factors in choosing the project site. Due to its position, the building has easy access to urban infrastructure, public transportation, and established infrastructure for the supply of power and water. The site for the project was chosen after careful consideration to meet not only the physical requirements of the company but also all the criteria for a genuinely Green project in a city like Pune, which is a little task, but a site in

seems to fulfill all the requirements and is opposite the well-known Magarpatta city. The site had the advantage of being located within an already-developed area planned by corporate offices and residences. Located in the city of Pune or a site area of around 10 acres and a built-up area of around 75,000 square meters, the project was completed in 2009. It cost around rupees 280 crore rupees which is approximately equal to 63 million U.S. dollars This long one at campus accommodates approximately 2500 employees. It is one of the few campuses in India that uses 100% renewable energy. The name on earth is dedicated to our precious planet and reinforces the belief that coexistence and responsible use of natural resources is the only way to achieve sustainability. The name One earth is designed to draw attention to the fact that we have only one earth, and we need to preserve it for a

future. In keeping with the one-hour theme, the names of the functional blocks and the campus represent the five renewable elements of nature: fire, water, wind, sky, and earth. The only instruction to the architect was to create a global high-technology campus in which the visitor could feel the touch and essence of being in India, leaving the motto of the company powering a greener future, the architect relied exclusively on non-toxic and recycled materials.


Design Process

Beginning in 2005, the architect fixed the fundamental concept of a central gathering place open to the sky, starting the design and building process. The campus had an upscale atmosphere thanks to it; it took the shape of a secret garden. The main area is designed as a garden, which is emphasized by the water streams that descend in the shape of a waterfall and end in a pool of water. The central court's enormous water feature contributes to better air quality and evaporative cooling. An

, also known as a Deepastambha, stands in the middle of this pool and is emphasized by many lighting. The group of glass chimneys is yet another recognizable aspect of this property. They are three in number and draw air from the cellars. Virtual instances of axial arrangement are the Deepastambha, the waterfall and glass chimneys, and the central corporate atrium, all arranged in a line. These serve as the campus's focal points. The Corporate Atrium's large circular enclosed glass garden, from which the water of the grounds emanates and flows, mimics the concept of the courtyard. These components are among the few that support the concept of a Green Building complex by reflecting the idea of a Land Scraper instead of a Skyscraper.


Making it a Zero Energy Project

The school saves 65% of its energy by using LED open-air lighting systems. Nearby photovoltaic panels and wind turbines generate 8% of the campus's annual energy needs at a yearly cost of about 11%. It is a Zero Energy Project since 92% of energy is obtained through renewable sources. These elements have allowed the campus to receive the Teri Griha 5 Star and Leed Platinum certifications. No other structures have a certificate from LEED so high. Large organizations need to start embracing sustainability, and the world progressively realizes that. They also need to design their structures with environmental sensitivity.


Transit

While adequate parking space has been allocated to facilitate the large number of staff who use the campus, the One Earth campus, which includes the office complex and the corporate learning center, can house about 2500 people. As a result, a smooth and efficient transportation system was an essential factor in the design. Initiatives have also been initiated to reduce

, such as carpooling, were strongly promoted. The company bus service for one-earth employees provides pickups from convenient locations around the city. The project has also offered easily accessible parking spaces near entry gate lobbies in the basement of the building. 5% of the total vehicle parking capacity is marked as dedicated parking for carpooling. The parking lot for the scene has been designated and branded preferential parking places, and 96 E charging outlets in the basement can service more than 3% of the building's residents.

To stop soil erosion and collect extra water, drainage mats have been placed beneath every soft landscaping section on the stage. The goal of the project was to increase building water efficiency. These high-efficiency fixtures have been installed, such as dual flush toilets, urinals with hydronic urinal electronic sensors for automatic flushing, efficient flow plumbing fixtures pressure reducing devices, and water-conserving shower heads reusing storm water and

, which further reduces the burden on municipal water supply by reducing the demand for potable water and reusing waste water. The services for nonpotable uses, such toilet and urinal flushing, have also been connected with mechanical systems and custodial purposes. Different native or naturalized species with shallow water requirements and upkeep make up the landscape design. The use of native plants in the landscaping has helped to cut the need for irrigation by roughly 18%. By creating appropriate habitats for birds and butterflies, it aims to increase

in addition to taking into account the functional and psychological needs of humans. The ability of various native plant species to adapt to the soil and temperature of the area has been taken into consideration. The water usage of air conditioners has been cut by around 50% by using recycled or captured rainwater. Effective water chillers were chosen to achieve this. The projected amount of potable water needed for a cooling tower in the water-cooled chillers. For process water used in air conditioning systems, the view of storm water or grey water generated on the property has also been taken into consideration. A STP, a sewage treatment facility with a daily capacity of 120 kiloliters, is used to treat all wastewater produced in the buildings, including that from the kitchens, restrooms, and washing areas, to tertiary standards. The cleaned water is appropriate for flushing and HVAC uses in the landscape.https://www.grihaindia.org/sites/default/files/sites/default/files/pdf/case-studies/Suzlon-one-Earth-final-rating-1May2013.pdf These are some of the statistical data of reduction in water consumption at Suzlon one earth * 65% reduction in building water consumption by use of low flow fixtures is achieved * 55% of water is recycled and reused within the campus * 50% reduction in landscape water consumption was attained by planting native species of trees and shrubs and by using efficient irrigation systems

, it lowers the building's energy needs. In brief occupancy places like cafes, gyms, and employee lounges, systems like indirect evaporative cooling have been employed to help maintain acceptable temperatures of roughly 25 degrees Celsius and avoid the need for air conditioners. This has assisted in lowering the project's overall air conditioning requirement by about 300 tonnes. Contrary to the building's traditional ducted system, fresh air is pulled into the basement through sizable vents and pushed by a programmable logic controller panel. Dual-speed jet fans in the basement's center are controlled by the PLC. An exhaust fan collects the bad air at ten spots and blows it onto the terrace level. The CO2 sensors' signals, which can only operate when necessary and so further reduce electricity use, are used to control the functioning of the fans.

Materials and Resources

Any project that seeks to be sustainable must prioritize reducing the trash that is typically produced throughout the construction process. The effective segregation, packing, and diversion of building waste for recycling to the proper vendors or channels was quantified as part of a construction waste management plan for one earth, which avoided landfilling dumps.

, gypsum wallboard, carpets, and insulation were all recycled in some way. On the construction site, areas were set aside for the segregated or mixed gathering of recyclable items. Recycling activities were monitored all through the building process. The company partnered with NGO Swatch for the collection of recyclable materials from the construction site. Arrangements were made for operational management of waste by installing segregated waste collected units for recyclable materials on every floor. Construction haulers and recyclers handling the chosen materials were identified. By using materials with a higher recycled content throughout the project's construction, it was hoped to lower the embodied energy of the structure and lessen the effects of energy extraction and processing. The entire energy needed to extract, process, manufacture, and convey construction materials to the site is known as extensive materials displayed energy. Materials that can be delivered within an 800-kilometer radius are referred to as regional materials. The project sought to increase demand for building materials and goods that were extracted and manufactured in the region, thereby supporting the regional economy and minimizing the environmental impacts associated with transportation. The project used about 80% of restricted materials, which is notable by any standards. Plants collected within a ten-year cycle or less generally yield materials that are quickly regenerated.

, and cork were employed in the project's interiors and were used for the flooring skirting ceiling tiles, walls, and partitions. Encouragement of environmentally conscious forest management was one of the project's goals. Therefore, only certified wood was used to satisfy various virgin wood requirements, and efforts were made to use at least 50% of wood-based materials that are certified in accordance with the guidelines and standards set forth by the Forest You Worship Council for complete buildings and components, including structural systems. Using post-tensioned slabs, it was possible to reduce the amount of structural steel and concrete by 50% and by 75%, respectively.

flash blocks were utilized to improve the building's insulation. The zero waste policy was put into place at One Earth to guarantee efficient waste management at the source and awareness among the building's residents. In order to eliminate waste completely, the zero waste policy directs people to restructure their resource use system. Additionally, it aids in spreading the message that in order to create a green working atmosphere, resources like paper, cardboard, food, etc. should be used carefully. The essential idea that waste management begins at the individual level and that the person producing garbage should be aware of its importance is projected by the policy.


Indoor Environmental Quality

It is well acknowledged that our built environment has an impact on people's comfort, productivity, and health. By increasing occupants' exposure to natural light, having a calming effect on the mind, and maintaining acceptable
indoor air quality Indoor air quality (IAQ) is the air quality within and around buildings and structures. IAQ is known to affect the health, comfort, and well-being of building occupants. Poor indoor air quality has been linked to sick building syndrome, reduced ...

and their working conditions. Such structures not only increase human comfort while lowering power and water usage, but they also have a favorable effect on general productivity and well-being. It is seen that a person's level of job satisfaction is influenced by how they feel about their workplace. In order to increase productivity and have a favorable psychological impact on employees, horizontal louvres were employed to let the most daylight into the office while keeping the glare and heat out. 90% of the rooms have views of the outside. It is thought that having access to a window that provides enough light and a view of the outside world benefits residents and influences how happy they are with their workplace. Various lighting configurations foster a pleasant work environment, provide staff members control, and aid in energy conservation. Each workspace's lighting can be individually adjusted to the comfort of the users, which lowers the energy use associated with central lighting or uncontrolled lighting. One of the factors is to make sure that the indoor air quality is suitable for the building's occupants.

The entire one earth campus is a strict no-smoking zone, and the management of Suzlon has eliminated its smoking policy to ensure that the global environmental concern is addressed even at the individual and corporate level. Human comfort is significantly influenced by lighting. Over 90% of the regularly occupied spaces have individual lighting controls, which provide people choice and aid in

. However, too much can be just as unsettling as too little. Each cabin occupant has their own lighting settings, and task lighting is installed at workstations. A special effort has been made to guarantee that polluting zones, such as restrooms and copier rooms where chemicals are employed, have deck-to-deck full-height partitions with self-closing doors that suck air from the outside or from nearby occupied spaces and make up all of these places. All exhaust locations have been carefully chosen to be at least 25 feet away from fresh air intakes or air handling equipment. Copier rooms feature separate exhaust systems and adjustable air pressure so that contaminated air does not mix with the fresh air supply and air conditioning.
