BANGALORE - CLIMATE ZONE - MODERATE
ISHWARI GORWADKAR - SEMESTER 3 - 2024 - 2025
Environment and Architecture module revolved around designing a space as a climatic response to a particular region. There are 6 climatic zones in India.
My group looked at the Moderate zone where our site was Bangalore, Karnataka, we first observed what the climate is like in Bangalore, the rainfall, wind, sun path, temperature and humidity, made climatic charts of the same, identified the challenges the zone may face and as a response developed strategies by introducing structural and design members such as sun spaces like courtyards, verandahs, balconies, fenestrations from the windward sides to improve ventilation etc. We also studied the site, the plotted area and the context around it, the proximities to other built forms after taking all these things into consideration we were then able to arrive at how our design should be.
In the south west of India lies Bangalore , a city situated on the Deccan plateau at an elevation of 900 meters above sea level.The city terrain is characterized by a mix of gently rolling hills and valleys. Now a IT giant the city was once a British cantonment.
Large deciduous trees create a canopy over the houses, their leaves rustling in the wind. Coconut trees add a tropical touch to the scene. Though Bangalore is mostly flat, this part of the city has a slight rise, with the western areas being a bit hilly. The landscape is shaped by these gentle slopes, allowing water to nourish the land.
The homes are designed with nature in mind-courtyards offer peaceful spaces for families to gather. As seasons change, the trees lose their leaves, carpeting the ground in gold, while the coconut trees remain a steady presence This area, with its mix of traditional houses and rich plant life shows how people and nature can live in harmony
The city's weather is generally pleasant, with mild winters and warm summers. This is relatively moderate compared to other Indian cities that experience more extreme temperatures.
Its lush greenery is a haven for diverse avian life. The vegetation comprises a mix of tropical and deciduous trees, While not a wildlife sanctuary, Bangalore's urban forests are home to small mammals like squirrels and mongooses.
In a peaceful part of Bangalore, the land gently slopes from the southwest to the northeast, guiding water to where it enriches the soil on the north and east sides. Traditional houses with sloping Mangalore tile roofs sit among this greenery. These homes have deep verandahs and open courtyards, perfect for enjoying the cool breeze that flows through the area.
To take advantage of the prevailing winds the built form is oriented north-south, with large openings on the north facing wall allowing diffused light throughout the year. To reduce the heat gain inside the house and maintain indoor temperature windows with vertical or horizontal shading are oriented on the east- west sides allowing winds to pass through promoting cross and/or natural ventilation. Using sun spaces such as courtyards,shades verandahs, balconies and pergola allow natural light creating buffer spaces in between the inside and the outside making it one with nature.

CLIMATIC STUDY
SUNPATH ANALYSIS
We did an analysis using the 3D PD Sun Path software to trace the path of the Sun and designed fenestrations according to it. We traced the paths of Summer Solstice - 21 June, Equinox - 21 March and Winter Solstice - 21 December. This analysis helped in understanding how much sunlight will enter our build form and how we can modulate it throughout the year. Bangalore receives most light from East and West, so vertical shading devices can be used on both sides, with South having horizontal shading devices. The fenestrations on the North face of the building can have fenestrations with less to no shading devices because it gets difused light throughout the year.
RAINFALL
The major rainfall occurs from May to October, highest in July. With precipitation being least in the months of December to March. With an average of 1300mm. During the monsoon temperature is slightly lower due to cloud cover and increase in humidity so you feel colder than it actually is.
TEMPERATURE ANALYSIS
Hottest days - April , summer lasts from February to May.
Coldest days - November and December. Bangalore is a moderate zone, the days are warmer and the nights tend to be cooler.

NARRATIVE
A ramp gently elevates you to a shaded verandah, where a cool breeze welcomes you from the southwest, drawing you into the house. As the breeze flows through the large windows on the East and west side, the house reveals itself as a space of seamless life and movement. The living room, with its high ceilings, breathes openness, while the kitchen, with its lower ceiling, feels intimate. Flexible furniture allows each room to adapt around your daily life. The lift, centrally placed, subtly separates spaces, with foldable partitions near the landings keeping a curious eye out.
The house's levels are thoughtfully designed so that common areas are visible from the bedrooms, yet the reverse is not possible, maintaining a balance of connection and privacy. Upstairs, the first bedroom overlooks the living room and has balconies that double as sunspaces facing the North side, perfect for soaking in the morning light. Another bedroom sits on a higher level, overlooking a serene corner courtyard that blurs the line between indoors and outdoors.
At the top, the terrace garden invites gatherings, where a secluded bedroom accessible by only a staircase hides behind the pergola. An external staircase weaves through the house, connecting balconies and leading to the top, ensuring a constant connection to nature’s sounds and light.
