Suzlon Energy Limited, a world-leading wind energy company based in Pune India, together with the architect, pledged to create the greenest office in India. The Architect calls the Tanti Family true patrons of architecture comparable to the Sarabhais, the Guggenheims and the Rockefellers. Living the motto of the company, ‘powering a greener tomorrow’ , the architect relied exclusively on non-toxic and recycled materials. A million S.F. of ground plus two levels in a 10.4 acre urban setting achieved a LEED Platinum and TERI GRIHA 5 Star certification with 8% of its annual energy generated on-site through photovoltaic panels and windmills 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. With 92 % (4 MW) being consumed by the project is ‘sustainable energy’ making this a Zero Energy Project!

Suzlon One Earth derives its inspiration from large Indian historical campuses like Fatehpur Sikri and the Meenakshi Temple complex in Madurai. This took the shape of a Land Scraper, opposing the idea of a Skyscraper! It is a counter blast to “the glass box.” A series of served and server spaces were created to adopt to the transformational nature of the business over the years. The Served Spaces cover the lion’s share of the campus that can accommodate modular walls and furniture systems. These are served by more rigid cores that house wet areas, utility shafts, ducts, fire stairs, elevators, entry and reception areas that will not change over time.

“Modules” like the silo fire stairs; the benchmark glass cylinders and the 8.4 by 8.4 meter modules that can be used like a Lego Set and moved about in one’s mind to create internal and external spaces. The design process started with a premise of creating a central gathering space, or Brahmasthan, with the sky as its ceiling! There is a sense of connection between the various kinds of spaces right from the underground entries vide the sunlight that descends there from the Sky Courts and the Glass Cylinders and the vegetation that flows from these elements, up through the cylinders into the main circulation nodes of the building.  The Deepa-Stambh is set in the centre of the Suzlon reflecting pool.

The pool rests at the basement level, wherein all of the cafeteria and the dining room open onto the water. In the background these see a cascade of water falls, flying down three levels of tiers, with traditional step-like objects giving rhythm to the backdrop. Large water body in the central court helps in improving the air quality and for evaporative cooling. All the external landscape areas are brought into the indoors along the perimeter of the building bringing fresh air, nature and natural light into the work areas so as improve productivity of occupants.

Building green, living smart

Pune and pimpri chinchwad lead the way in adopting griha rated green buildings.

The ‘Green Rating for Integrated Habitat Assessment’ or GRIHA is a rating tool designed to assess the performance of buildings and habitats against certain nationally accepted benchmarks. It aims at reducing carbon footprint, saving on energy and water consumption, adopting renewable energy systems and providing a visually and thermally comfortable indoor environment to the end users while simultaneously reducing 30-40% of the operational cost.

Formulated by the griha council, an independent not-for-profit society established by the energy and resources institute (teri) and the ministry of new and renewable energy (mnre, government of india), the griha rating assesses projects over their entire life cycle i.e. from the initial design stage through the time it is operating., various municipalities and government organizations in india have adopted the griha rating to enable sustainable development through attractive incentives for both the developer as well the owner. for instance, the pimpri chinchwad municipal corporation (pcmc) provides a 10-50% rebate to developers on premium charges for griha and sva-griha (small versatile affordable griha) certified buildings (1-5 stars) while to the owner it gives a 5-10% discount on property tax for 3-5 star griha certified buildings and 5-15% for svagriha rated buildings., here are a few glimpses from some of the griha rated environmentally sustainable green buildings in the area of and around pune, maharashtra –, royal orange county, pune.

The Royal Orange County has a total of 207 flats. The complex is built using sustainable materials; it generates 120 kilowatt peak of solar power, treats 250 kilolitres of sewage through a low-maintenance natural STP, and has a rainwater harvesting capacity of 12 lakh litres. It is one of the first residential projects in India targeting a 5-star GRIHA rating.

Palladio, pune.

The Palladio has achieved a reduction in landscaping water demands by using not only the STP treated water but also planting native species that require less water. It features a solar hot water system that suffices its 100% hot water requirements thereby reducing the consumption of energy generated from non-renewable sources. It also has on site a vermi-composting system that treats 100% of the organic waste generated in the complex.

Vvip circuit house, pune.

Pune’s VVIP Circuit House not only boasts of an on-site solar photovoltaic of 22kWp rated capacity but also features a phytorid technology based sewage treatment plant of 25kLD capacity. The landscape too has been designed to maximise green cover with the paved area coming to only around 21.32% of the total landscape area.

Pimpri chinchwad new town development authority, pimpri-chinchwad.

The net paved area on site at Pimpri Chinchwad New Town Development Authority (PCNTDA) is less than the 25% benchmark as per GRIHA requirements with the EPI of the building coming to around 17kWh/year/annum. It also features a solar photovoltaic of 100 kWp rated capacity with all of the outdoor lights being equipped with timer based automatic controls.

Change in climate, caused by the release of greenhouse effect causing gases (primarily carbon dioxide) into the atmosphere, has been recognized as one of the greatest threats of the 21st century. Share of the global energy consumption in India and China has also been on the rise due to heavy industrialization, urbanization, population explosion, and intensive growth of IT. Buildings are the prime energy consumers in modern cities accounting upto 40 to 45% energy consumption. Their consumption can be largely confined through improving efficiency, which is an effective means to lessen greenhouse gas emissions and slow down depletion of fossil fuels. There is a heavy (over 50%) saving potential in the building sector and thus it is considered as a potential sector to meet the challenges of global energy demand and climate change. Along with the advent of energy efficient measures, more effective means are needed to induce or compel greater efforts, especially to the signatories of the Kyoto Protocol. This technical paper highlights the importance of sustainable construction, discusses role of energy efficiency in green buildings in Indian context to reduce the energy consumption and environmental degradation through Green House Gas emission (GHG). Also it points out to the benefits of green construction as well as the incentives from govt. and municipal bodies for GRIHA certified green building.

Convergance of Government Policies and Green Retrofitting in India to study the possibility of developing New Delhi as a Green Capital.

Gaurangana Sood

‘Green retrofits’ are any kind of upgrade at an existing building that is wholly or partially occupied to improve energy and environmental performance, reduce water use, and improve the comfort and quality of the space in terms of natural light, air quality, and noise-all done in a way that is financially beneficial to the owner. However the application of Green Retrofits is a process that has to be designed to especially pertain to various aspects of a building like its age and its climatic positioning. Retrofitting can be carried out for an entire building or for one or more working systems of a building in order to improve a its operations and maintenance (O&M) procedures to enhance overall building performance. This study examines the scope for developing Delhi as a Green Capital through retrofits, highlighted by examples of existing models, and the role of Government Policy making in promoting sustainability. Through an interdisciplinary framework of economic, demographic, climatic and architectural studies the paper provides a holistic view of the Country’s capacity and challenges in Greening Delhi through retrofitting. Using in depth analysis of Green Rating Systems and the role of Energy Servicing Companies, this study traces the possibility of developing Delhi as a Green Capital through Retro commissioning corroborated by Government policies with consideration for its existing structural model and climatic conditions. The study concludes that Green building practices can be promoted in Delhi by the central government providing incentives and issuing mandates for adopting sustainable building codes and the State government and Municipality taking initiatives to enforce them. It also highlights the role of private and public stakeholders and the importance of awareness about Green Building Practices amongst developers and communities.

There are three rating systems available to assess the sustainability of Group Housing in India provided by three agencies, namely the Indian Green Building Council (IGBC), Green Rating for Integrated Habitat Assessment (GRIHA), and Eco Housing Assessment Criteria's. The parameters for all three rating systems have some differentials. The building rated under one rating system may not obtain a rating under another rating system. It means that designers' attention is restricted to the rating system's criteria and has lost the sustainable design process's true spirit. This paper aims to establish the Principles of Design that meet all the rating system's maximum criteria. The methodology followed for this paper includes a brief review of all rating systems and a comparative analysis of similarity and dissimilarity to understand the key focus areas of all three rating systems. The Principles of Design are applied to fulfill all the three-rating system requirements with each focus area. The applications of design principles in the project indicate that only a certain number of Principles of Design are applied to achieve the rating system in each project, and many Principles of Design are overlooked. This was due to the designer's approach to sustainable buildings as a product based on the rating system. The Principles of Design generated in this paper will be a ready source of guidance for India's sustainable housing design. The designer should initially approach sustainable design as a design process and, later on, achieve a sustainable design for a specific rating system.

The building sector is one of the biggest consumers of electricity in India [1] ; it is also the largest generator of CO2 emission & one of the highest consumers of water in India. This is the basic reason why Green building movement comes to India so that we can minimise the environment effect caused by the construction activity in India. Green buildings have potential to reduce up to 34 percent lower CO2 emissions, consume 25 percent less energy and 11 percent less water, and have diverted more than 80 million tonnes of waste from landfills [2]. The author of this paper has studied different rating systems in India & the sustainability of the green buildings in India. The paper goes beyond Green building rating system and gives a thought to the understanding of embedded emission and operational emission. The author of the paper gives an idea of not only Green Building but also a sustainable green building by Post occupancy evaluation.

The main focus of this study is to outline the subtle distinct features in the "Energy" modules in green building grating systems i.e. Green Rating system for Integrated Habitat Assessment (GRIHA) and Indian Green Building Council (IGBC). For which we will start up with the building model being simulated in an energy simulation software/tool that are certified by competent authorities. The results as obtained from the simulation of the proposed building model will be used. Since, there are different benchmarks for allotting credits for achieving minimum energy efficiency such as Energy Performance Index (EPI) in GRIHA and percentage savings in energy consumption cost in case of IGBC. Keyword: GRIHA, IGBC, eQuest, Green Building I. INTRODUCTION Buildings are key to a sustainable future because their design, construction, operation, and the activities in buildings contribute significantly to high energy consumption-reducing energy demand in buildings can play a pivotal role in reducing energy consumption and solving challenges that lies ahead. Energy services in buildings-HVAC systems for thermal comfort, refrigeration needs, lighting systems installed, communication and entertainment (such as Television's, Laptop's, other accessories), as well as other amenities are majorly responsible for a significant share of energy use worldwide. Several energy-related problems affecting human health and productivity take place in buildings, due to poor indoor air quality or inadequate indoor temperatures. Hence, this issue must also be addressed to improve occupant's health and increase efficiency of people working inside these buildings. Reports includes that India's National Development Council is centered around the building sector based on energy conservation, vowing to make its Energy Conservation Building Code (ECBC) stricter, featuring its local building rating system GRIHA (Green Rating for Integrated Habitat Assessment), which is used for scaling the green building and energy efficient projects in the country. With rapid urbanization, as the quality of life improves, more and more people are being lifted above poverty line, and easy access to electricity. EIA projects that electricity's share in the total use of energy in buildings will nearly double in non-OCED countries, from 21% in 2018 to 38% in 2050 as compared to electricity's share of delivered energy consumption in OCED countries buildings will decrease from 24% to 21%. Kibert [1] through their research portrayed that Green buildings are built on the basis of ecological principles and the effective use of natural without compromising robust facilities. As per WGBC [2], Green building facilitates the preservation of precious natural resources and the improvement in the overall quality of life. The term Green Building can be easily understood in broader sense as the building or facility that consumes less amount of energy as compared to conventional buildings, reduces the dependency on energy supplied by grid, instead employs renewable energy sources, reduce their water demand through water harvesting and other techniques. The principle of "reduce, reuse and recycle" is relevant to green buildings. Zuo & Zhao [3] concluded that there is a need to evaluate the coverage of social and economic aspects of sustainability in green building rating and support the development of new ratings. Feng et al [4] Apart from short-term and long-term benefits that green building provides to its occupants, a green building needs to be economically rational. Analytical Hierarchical Process (AHP) is used to evaluate the relative significance among common components that contribute to sustainable buildings. Many rating systems that were studied were noticed to perform only a part of their originally intended objectives with energy efficiency taking the highest priority [5].

Text description provided by the architects. Circuit house is a government public building which not only accommodates the VIP authorities but also acts as a node for political meetings, government authorities’ discussions and conferences. Usually, circuit houses have large number of visitors and occupancy can vary extremely. The project site is located in Pune - political hub for western Maharashtra. The project is mainly divided into two parts-

- Accommodation - Guest suites

- Public areas –Conference and meeting hall facilities, Dining, Reception, VIP and visitor’s waiting areas etc.

Design is based on climate responsive architecture with passive strategies for thermal and visual comfort along with innovative active strategies to achieve energy efficient green building. The project has received GRIHA Five star rating.

Today architecture has become threat to our planet. One has to be conscious while using natural resources for any development on the earth.

Hence green and sustainable architecture is not just a trend but a lifesaving measure for our earth and so the sustainable green architecture is no more a distinction as a design concept. In fact it shall be the basic ethos for all the development.

Government buildings are normally perceived as menace to sustainability as they consume high energy because of basic lacuna in the planning and design. This project is an initiative to make Government buildings “Green and Energy Efficient” and to create awareness in the government sector.

Our focus here is to design a climate responsive building with passive strategies for thermal and visual comfort along with innovative active strategies to achieve energy efficient green building. 

We also believe that, “Architecture shall adhere to its time, the era, in which it is built.”

The contemporary architecture of this building has been derived from vernacular ethos. The shaded courtyard, which is the focal point of the building and passage around it leading to suites, is a highly contemporary version of the ‘old chowk’ of traditional Wadas of Pune with interiors and landscape seamlessly merging with architecture.

This project is designed following all passive strategies of planning, fenestration, zoning etc. 

Central shaded courtyard and spaces around it are well protected from sun yet allowing plenty of natural ventilation. The facade of the building responds to the orientation. Transition spaces play a key role in achieving thermal and visual comfort. Following table shows the details of energy efficiency achieved in terms of lighting, water, HVAC and materials.

10 POINTS OF GREEN STATUS

1. The project is Griha certified with 5 - star rating for green building.

2. The building design is completely based on solar passive, climate responsive architecture. All the areas are naturally day-lit and ventilated with optimized shading devices designed to control glare and heat gain achieving thermal and visual comfort.

3. The building envelope is a crucial element of green building, hence each facade in this building is designed taking into consideration its orientation and function. Vertical and horizontal Louvers have been used for south and west facade to cut the solar radiation.

4. 22 kW solar photo-voltaic renewable energy plant is designed to cater more than 30% of artificial lighting. 100 % outdoor lighting catered by renewable energy system 

5. Double glazed windows with low Solar Heat Gain Coefficient is used to minimize direct heat gain from the windows & to reduce air conditioning load. Highly efficient HVAC system (VRV) brings down the energy performance index (EPI) of the building. 

6. 52.81 % reduction in building energy performance index (EPI) is achieved in this design.

7. 90% of hot water demand is catered by heat pump based hot water system.

8. Efficient water fixtures have been used, resulting in 50% water conservation. Waste water has been utilized for landscape irrigation. 

9. Native & drought tolerant species with efficient irrigation system are proposed in landscape to minimize the water requirement for landscape. Irrigation water demand is reduced by 48% by the use of treated water from the STP installed on site. 

10. Building execution is done with all safety measures & procedures, innovative green construction techniques and effective air and noise pollution control measures.

Product Description. LOUVERS. In a hot-dry climate as that of Pune , creation of an apt second skin as the building envelope is one of the most critical factors for a sustainable approach. Similarly even in The Circuit House, this second skin ie, the louvers on the west and south façade of the building plays a very important role in limiting the amount of solar radiation and light admitted into the building. A combination of vertical and horizontal louvers has been adopted, each placed at precise angles, thus achieving thermal and visual comfort for the occupants. The reduction in solar radiation helps in limiting the heat gain hence reducing the load on air conditioning. Overall it helps in improving the energy performance of the building, and achieving green building status.
