Sun, Wind, and Light by Mark DeKay provides quantitative solar geometry and wind ventilation formulas. AGNAA Design Studio uses solar path analysis to angle exterior louvers at 45° on South/West facades and orient wind catchers toward prevailing South-West summer breezes, reducing mechanical air conditioning reliance.
In *Sun, Wind, and Light*, Mark DeKay and G. Z. Brown establish that true sustainability comes from geometry and microclimate orientation rather than expensive mechanical equipment. At AGNAA Design Studio, we analyze solar radiation paths for every site in Hyderabad.

West facades require vertical louvers, cavity walls, or dense tree canopies to block low-angle afternoon sun while permitting ambient natural daylighting.
Thermal lag is the time delay for heat to travel through a wall. AAC blocks and thick stone masonry provide a 6–8 hour thermal lag, keeping interiors cool during peak daytime heat.
