Built to Chill: A Guide to Indian Architecture
Nestled in the heart of South Asia, India is a land of diverse topology, from the towering Himalayas in the north to the tropical coastline in the south, the presence of which elicits a wide range of weather patterns. The country's ancient architecture has evolved over the ages to fight the burning heat, which remains a recurring challenge.
The story begins with the Harappan civilization (2600-1900 BCE), which has one of the first examples of urban planning and construction. The well-designed structures of Mohenjo-Daro included houses built with thick mud walls that provided excellent thermal insulation, keeping the insides cool throughout the scorching summers.

In the medieval period, the construction of step wells and baolis (traditional Indian water tanks) played a crucial role in ventilating the surroundings. The water bodies acted as natural air conditioners, with the cold air rising from the wells providing relief to the locals. Courtyards, in Indian houses, were central to residential design and provided natural airflow and shade, reducing house temperatures.

The arrival of the British brought several architectural reforms, and soon, the West began to influence Indian house styles. During the colonial period, bungalows, single-story houses with sloping roofs, and large verandas gained popularity; these were ideal for India’s hot climate. The verandas acted as traditional spaces, allowing inhabitants to enjoy the outdoors while remaining protected from the intense heat.

As India moved towards the 20th century, traditional techniques regained prominence in combating the summer heat. Jaalis, intricately carved stone or wooden screens, became a common feature in houses. Placed strategically on walls or windows, jaalis facilitated cross-ventilation while preventing direct sunlight from entering the interiors.
Chajjas, or extended overhangs or eaves, provided shade to the windows and walls, shielding them from the harsh sun rays. These architectural elements helped maintain comfortable indoor temperatures, reducing the reliance on artificial cooling.

Sustainability has recently gained salience, and Indian architecture has seen a revival of old methods coupled with new technologies. To ensure that buildings are summer-friendly, designers and architects have adopted eco-friendly practices.
As apartments have begun replacing row houses with pre-made designs, it has increasingly become difficult to incorporate traditional designs in our daily lives. This has given rise to making green roofs and terrace gardens, which act as natural insulators and reduce heat absorption. Additionally, the use of low-emissive glass windows minimises heat transfer, while solar panels provide clean energy for cooling systems.

Thus, both ancient techniques and innovative adaptations have been used to build comfortable living areas throughout India's history. Moving forward, it is essential to appreciate and conserve our architectural history by encouraging sustainable designs that respect tradition while embracing technological innovation.
