Climate responsive architecture in extreme climatic zones of India
Recently, the presence of global climate change has been very prevalent. Considering that buildings and their construction amount to 36 percent of global energy consumption and 39 percent of energy related carbon emissions, it is high time we try and reduce the carbon footprint of our architecture and methods of construction.
This project aims to demonstrate detailed design strategies, passive design interventions and overall hopes to reduce the building’s reliance on artificial sources of comfort; On a site where the building also has to respond to the harsh climatic conditions and geographical contexts of Shillong, Indian.
The southern block is lower than the northern block to accomodate forsunlight and to provide a slope for the solar panels.

Light weight thermal massing done to walls
Only a portion of the site gets a large amount of sunlight and only in the Southern direction.
-According to the sun path(andaccording to climate consultant) the most amount of radiation recieved on site is during 8 am - 2 pm in the day -15 - 25 degree is the tilt provided for the solar panels to aquire maximum raidation.
-Sunspace corridors towards the southern direction is an intevension provided for maximum solar heat gain.
- The vent are used to help diffuse some of the heat gained by the intervensions during summer to avoid having an uncomfortable atmosphere as well as provide ventilation for the humidity.
THERMO BI METAL (used in thermostats or circuits) : is used as a trigger which will open or close the shutter. The thermo bimetal is connected to a spring mechanism.
When the sun shines on the metallic strip , it curls and creats tenssion in the spring, allowing the shutter to open and increase the solar heat gain through the glass surface. When the sun stops shinning on the metal, it unclurls, and the shutters close.
LIGHT WELLS to provide light to the lower areas

Large scale projects in an urban context have multiple restrictions; The main one being building Bylaws. This project is an introduction to maximizing area usage while providing multiple recreational and community areas throughout. It also looks into the world of community spaces and creating semi public areas for the community.
The project site is located in Basavanagudi, next to a junction of main roads. The design intends to give people a space to get away from the hustle of the busy roads (both living in the social housing project and outside ).
Since the project is located in a junction which experiences a large number of vehicles throughout the day, the addition of Acoustic Louvers was done to help provide a peaceful environment and protect the occupants by the filtering noise from the main roads.
The design accounts for a space in the south-west corner of the site as the place obtains adequate light and ventilation and is right next to the Ram Krishna Ashram.
Cut out area
Cut out for light to filter in to the lower levels
The spaces provided in the center of the structure creates blocks and separations in the project which provides sunlight and ventiltion to filter into the building and prevents it from being claustrophobic. The blocks are connected to each other with the help of bridges provided in between these blocks.
The spaces that are highlighted by the hatch are multipurpose spaces that may or maynot be used for terrace gardening or as a play area for children etc. Or as a small community space on each floor.

HOW DO WE MAKE A LITERARY CENTER A SPACE FOR THE PUBLIC? AN AREA OF PUBLIC INTEREST .
This project explores the redesigning of a public space to be more inclusive and attract the public by being welcoming. This project focuses on the exploration of building skin.
Architecture involves the designing of spaces that can make us feel enclosed, liberated , comfortable or safe. This act leads us to react to the space; makes us slow down, speed up or stop to contemplate. Writers, in creating their literary structures, do exactly the same.
In architecture, once you remove the skin of the structure — the “language” of walls, ceilings and slabs — all that remains is space. In writing, once you remove language itself, the actual words, what’s left?
This design tries to bring out the contrast in skins between the multiple blocks as well as tries to build a connection between the literary center and the public.
The main intenet of this project is to provide a better designed structure for the existing literary center. The contrasting styles of the building are derived from the two genre of literature : - Fiction and - Non - Fiction
The Glass frame block ( highlighted in blue) depicting the fictional aspect of literature and the masonry block (highlighted in yellow) depicting the non fictional aspect.
The bridge in between sybolises the bridge between the two genre.
BLOCK A :
The material used to build the block is stone, brick and cement(mortar).
The solid imposing form represents the fact based aspect of non fictional literature.

DEVELOPING A SELF SUSTAINING MODULE
This project is designed to be as sustainable as possible. This Climate responsive structure, for a private client, is made efficient by using multiple softwares and passive design interventions.
Angshuman
The designing of a small sustainable building was to be an introduction to the concept of building a climate responsive building and sustainable thinking. This is a building that aims to be as sustainable as it can and is calculated and proved to be a NZEB building.
The project was located in Kotagiri, A hill station experiencing a maximum temperature of 24° and a minimum temperature of 7°. Kotagiri has a large number of fields and step plantations which often grow coffee. The Project is located in a plantation, at the edge of the plantation bordered by a sloping terrain
A cover crop is also used for landscaping to prevent errosion .
Waterways are provided to collect rain water run off in the catchment area.
The Hydro electric motors are placed here to generate extra electricity during heavy rainfall.
A wood wool based structural insulated panel is used for this project to prevent the heat collected from escaping (thermal mass).
Eucalyptus trees are known to ve a tall tree with largely lateral roots. The building is placed 8 meters away from the tree to prevent the roots from being dammaged.
A sunsapce is provided here to collect heat due to the cold climate.
LIGHT ORANGE SPACES:
sun spaces provided along the large windows to retain solar heat gain.
ORANGE LINING:
rain water gutter that collects run off from both the roof and the fog water collection system.
PLAN AT 4 MTS (FIRST FLOOR)
the rain water harvesting gutters are depicted in orange. The Red shaded area is a fog water collection system from which water is collected using recycled mesh. This technique is used in multiple hilly areas.
INTERVENTIONS PROVIDED IN THE DESIGN:
- The roof has a tilt of 11 degree ( based on the sun path and thermal radiation charts and also has solar panels on the south.
- The roof is made of PUF panels that are pre fabricated and are very eco friendly.
- There is a sun roof on the top and helps heat the building from the top.
- The vegetative waterways surround all the trees to prevent any runoff to affect the trees and their roots.
- Conservatories , or sun spaces are used for maximum solar radiation absorption and retention.

5. INTERIOR DESIGN PROJECT
This Project is an Interior design project which is designed specifically for MAHARANI GAYATRI DEVI, an Indian public figure. The context of this project is the Neo Classical room from th movie; 2001: A Space Odyessey. The intent of the project was to design a living spcaes in a context that is completely out of the clients comfort zone but convert the space through interior design to fit the clients needs.
LOGO
DESIGNED FOR MAHARANI GAYATRI DEVI
Maharani Gayatri Devi was the third Maharani consort of Jaipur from 1940 to 1949.
She was a independant emodiment of the modern women with her feminist, open minded view of the world. She ran for parliment in the year 1962 and won the constituency in the Lok Sabha.
She was known as the Raj mata of Jaipur.
Multicoloured fabric ribbons are used to create a semi partition that is then extended to become a colourful canopy. This method is used to create separation in a room with a small area and an open plan.
The blue partitions are made of a smaller diameter rope to aid to the immateriality of the partition
A rope like blue canopy is provided above the bed to continue the canopy effect and to provide a shadow effect for the light facing the ceiling.
The dark blue canopy, to the right, is similar in concept but is designed to be made from elastic rope which aid the moveable partition. It is held in place using floor magnetic holders and magnets attached to the wall.

- The permiability and transparency of the partition walls provide a lighter and more spacious looking room ( less clostrophobic).
- The moveable partition allow for a change in room dimension and therefore a break in monotony.
-The partitiona and movement are derived from the game of polo which she adored during her youth

EDUCATIONAL INSTITUTE
LOCATION : BASAVANAGUDI, BANGALORE
The project was a montessori school designed as per solar decathlon criteria. It uses multiple softwares and passive design interventions in the hopes of becoming a Net Zero building.
Team members : Ankita L, Arivudainangai k, Bhakti Munvar, Sharmila Joshi, Devayani M, Gurucharan G, Jahnavi J, Pratik Tushar, Fariah Inas, Vaishnavi S, Nandita HL, Jyothsna BS
The context and micro climatic studies show the major problem areas and elements, such as noise, wind direction etc., that our building needs to address.
The sun shines largely in the southern direction and therefore the orientation is decided considering this observation.
The noise enters the site,due to the main roads bordering two sides, and therefore from that direction.
The fenestration is designed based on the wind speed and wind direction ( and daylight factor) primarily for ventilation.
Winds are not required to achieve thermal cooling conditions. It is better to catch rainwater from western sides.
The temperature and humidity levels are considered to maintain comfort levels (which are based on NBC standards).
Average temperature falls under comfort zone throughtout the year. Rainfall is high from August to October.
The Amount of rainfall is crucial in trying to design a NET ZERO building as water demand is an important criteria.
Tenbroeck Academy is a private entity, the first school in South Bangalore to extend the Montessori Method to grade 6.
This aims to provide a holistic approach in helping children develop a passion for learning and preparing them for life.
Their mission is to help children develop a deep-rooted sense of community and make them aware of their heritage, history and value systems by incorporating additional intense and comprehensive after school programs.
HOW WAS THIS APPROACHED FROM A DESIGN PERSPECTIVE ?
- Use of open spaces: The different open spaces are articulated to serve varied functions like OAT for morning assembly and other functions.
The Upper open spaces for extended classrooms and informal learning in green spacesIntegration of arches and vaulted structural system
- Non-conventional classroom layouts- aid montessori design: The montessori classrooms demand a more free and creative layout of furniture with more open spaces and functional elements; like blackboard shutters for cupboards and colourful paintings/mats on the floor instead of conventional table and chair layouts
Our water consumption has reduced drastically after installment of the Low Flow Faucets. The Fresh water being consumed by the municipality lines (city lines) reduces by 45 %.
Base case Municipal water demand : 5899166
Efficient system Municipal water demand : 3205320
Our base case water consumption was based on NBC which led to the consumption being 40, 500 L per day , using more efficient fixtures and a more efficient design we reduced the daily consumption to 23, 490 L per day. According to the water balance sheet, we have an excess of filtered grey water , which leads to the recharge pit (along with the ground run off) to help recharge the groundwater table.

Over the course of the sem we learnt to create multiple parametric forms(ie. the TOWER to the right and the moveable LOUVERS on the left). However, the most notable forms where:
SNOWFLAKE PAVILION
During the semester (5th) we looked at many techniques in creating parameterized forms. This snowflake pavilion was a result of that. The snowflake was created using four triangles as its base. The snowflake was then plugged into mesh in the form of the ring aligning pentagons.
SERPENTINE PAVILION
We created and experimented with parametric buildings and forms.
Using grasshopper, we learned how each value in the script is essential in the outcome of the final form. For example; We recreated the Serpentine Pavillion by BIG (or created a close copy of the original).
