Abstract

Providing natural light with daylighting in the interior space of a residential building is essential to sustainable architecture. This research reviews how different daylighting strategies affect energy use in Residential buildings in various climate zones in India. Due to drastic changes in climate variations across India, this research on daylighting strategy is unique. In each region, tailored techniques are crucial for energy preservation.

In this research, papers published in Scopus, web of Science, and Google Scholar-indexed journals from 2008 to 2024 have been included. Starting from traditional daylighting techniques, which are part of India's architectural heritage, such as courtyards, windows, and reflective surfaces till advances to more contemporary techniques like light shelves, skylights, and sophisticated glazing materials that are climate- specific and maximize daylight penetration while decreasing heat gain discussed in this research.

In India's hot-dry, warm-humid, composite, temperate, and cold climates, the effectiveness of techniques varies. This study also includes shading devices, window-to-wall ratios, and building orientation. This study's findings demonstrate that daylighting strategies have universal benefits, but some must be tailored to the climate-specific context to achieve maximum energy efficiency.

This extensive analysis will be helpful for the use of energy-efficient daylighting techniques that are sensitive to the region's unique climatic challenges and cultural landscape by serving as a resource for Indian architects, designers, and policymakers.
