4. I mplementation of green architecture is critical to create environmentally conscious and resource-efficient learning spaces in educational campus. Sustainable site planning, which includes factors such as appropriate building orientation and the incorporation of green spaces, not only improves the aesthetics of the campus but also increases biodiversity and air quality. Energy efficiency techniques, such as installing energy-efficient building systems and using renewable energy sources such as solar panels, help to reduce energy consumption and carbon emissions. Water conservation methods, such as water-saving fixtures and rainwater collecting systems , help to reduce water consumption and promote sustainable water management on campus. Indoor environmental quality improvements, such as appropriate ventilation and the use of low-emission materials , promote healthier and more productive indoor environments for students and faculty. Waste reduction techniques, which focus on reducing construction waste and encouraging recycling, help to ensure a more sustainable building lifecycle. Acknowledging and analysing these tactics can help to demonstrate a full understanding of the significance and impact of green building on educational campuses.

5. Composite climate Composite climate is a combination of hot-dry and hot-humid climates, with large seasonal variations and extreme climatic conditions throughout the year. The places that experience a composite climate include central India, central South America, and south-eastern North America It alternates between long hot, dry periods and shorter periods of concentrated rainfall and high humidity, creating a diverse range of conditions throughout the year. Temperature Ranges: In summer, the daytime temperatures in a composite climate can range from 32-45 degrees Celsius, while nighttime temperatures range from 27-32 degrees Celsius. Winter temperatures in a composite climate typically range from 10-25 degrees Celsius during the day and 4-10 degrees Celsius at night. Monsoon Influence: Composite climates receive strong monsoon winds from the southeast and northeast, impacting the humidity levels and precipitation patterns in the region.

6. Green architecture is a philosophy focused on designing buildings with the lowest possible negative impact on the surrounding environment by using sustainable materials and energy sources in construction. It emphasizes the importance of creating a healthy indoor environment for a building's inhabitants and aims to reduce the environmental footprint of buildings through efficient use of resources, energy efficiency, and minimizing waste. "The whole purpose of architecture is to make people happy, then we make it green at the same time because it’s an ethical thing to do for the environment.“ - Ken Yeang Benefits of Green Building Strategies Campus serves as a place for learning which allows students to experiment and enjoy the process of learning. Educational campus is is a which has various function .Students stay there for a long period of time. T he adoption of green architecture on university campuses is driven by the need to reduce environmental impact, achieve cost savings, attract top talent, provide educational opportunities, and align with broader sustainability objectives

24. Site and Design The linear geometry of the site with a narrow frontage and an aspect ratio of almost 1:3 dictated the strong linear axis in the design. Positioning the three distinct functioning zones in a hierarchy of public access to restricted entry formed the other key consideration in design development. Placing the commercial block at the front of the site. The functional core also coincides with the geometric central part of the linear site. Design responds to orientation and climatic factors . The north line is at a slight angle to the linear axis of the site and the design takes full advantage of this orientation in the composition of the built and open spaces and in creating wind flows through the complex as also lighting and shading of the spaces.

25. Sun Passive solar design is an important feature in the design of this building. The planning and orientation of spaces and building blocks ensures glare free daylight in all regularly occupied spaces . All the linear blocks are oriented in the East-West direction with shorter facades facing the sun. Most of the south west facing walls are kept blank in order to protect the building from the harsh south west solar radiations. Where the south west walls have openings, they are protected by means of pergolas or projecting balconies. The east, west and south facades of the building have minimum glazing.(William,2015)

26. EARTH AIR TUNNEL The Earth Air Tunnel (EAT) is used in the hostel blocks. This is a dual heating-cooling system using the heat sink property of the earth to maintain comfortable temperatures inside the building. Air which passes through the buried pipes gets cooled in summer and heated up in winter. WATER MANAGEMENT All buildings in the campus have been provided with low flow fixtures such as dual flush toilets, low flow taps and sensor taps that result in 25% savings in water use. The waste water is treated through efficient biological processes using a combination of micro organisms and bio-media filter. This treatment system requires less area and low energy . The treated water meets the prescribed standards for landscape irrigation. Rainwater harvesting is also an important concept which contributes to efficient water

Footpaths, cycle tracks, parking and benches will be provided to facilitate pedestrians and encourage walking/cycling within campus. Separate pathways for different modes of transport such as motorized and non- motorized vehicles are designed within the campus. Footpaths cycle tracks

34. Materials : Bamboo : Bamboo's environmental benefits include minimal soil disruption and a high rate of carbon sequestration. Recycled Steel : Steel is a highly recyclable material and is used extensively in construction . Utilizing recycled steel reduces the need for new raw materials and lowers the energy consumption associated with steel production. Hempcrete : This material is a concrete-like product which is lightweight, offers excellent insulation properties, and has a negative carbon footprint, as it absorbs more CO2 during its lifecycle than it emits. Plant-based Polyurethane Rigid Foam : It is used for insulation and is derived from renewable resources such as soybean and castor oil. It provides excellent thermal insulation while being non-toxic and emitting low levels of volatile organic compounds (VOCs). Green Roofs : IIM Raipur has adopted green roofs, which involve covering building roofs with vegetation. These green roofs offer benefits such as improved energy efficiency, reduced stormwater runoff, enhanced air quality, and extended roof lifespan.
