MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202641024459 A) filed by Chilakapati Anil Kumar, Vijayawada, Andhra Pradesh, on March 2, for 'a method for adjusting window openings based on external obstruction and setback conditions to achieve adequate daylighting.'

Inventor(s) include Dr Kranti Kumar Myneni.

The application for the patent was published on March 13, under issue no. 11/2026.

According to the abstract released by the Intellectual Property India: "The present invention provides a manual method for adjusting the physical dimensions of a window opening in a residential building design to achieve adequate daylighting. The method involves measuring site-specific geometric parameters, including the height and distance of external obstructions and the building setback. These measurements are evaluated against a predefined, rule-based criterion to determine a category of daylight reduction. Based on this category, a prescriptive adjustment-specifying an increase in the window's width, height, or area-is determined. The method outputs a specification for a permanently enlarged, fixed window opening. Crucially, the process is executed without reliance on computer simulations, performance prediction algorithms, or dynamic modeling software, providing a practical, accessible design tool for architects and a verifiable standard for regulatory compliance in obstructed urban contexts."
