Academicians and professionals in the architecture, engineering, and construction (AEC) field have expressed an increasing interest in sustainability and its application in the development of construction projects, especially with its deemed relationship with lean construction, for the purpose of improving efficiency in the construction processes. Practices framed under the lean philosophy show their potential in reducing environmental, economic, and social impacts during the construction phase, with an increase in the parameters of sustainability in the development of projects.

This paper aims to review the achievements of previous studies addressing the capability of atriums for providing adequate levels of daylight and visual comfort. This study also performs several simulations using Radiance IES-VE software predominantly with the target to support the literature review results. The analysis discusses ways of daylight transmission through different atrium structures.

The white paper puts forward recommendations for the coordinated enhancement of policies, codes, and regulations. It lay out a framework for guidance for the Ministry of Housing and Urban Affairs (MoHUA), the Ministry of Health and Family Welfare (MoHFW), and the Review Committees of the Bureau of Indian Standards (BIS) for the National Building Code (NBC), to harmonise their actions for healthy affordable housing in urban areas.
