Why Southern Orientation Matters in Tropical Dhaka Architecture

In tropical Dhaka, apartment orientation is far more than a personal preference — it directly dictates indoor comfort, natural lighting, and your monthly air conditioning bills. ### The Power of Southern Breezes (Dokkhina Batash) Dhaka experiences warm, humid weather for nearly eight months of the year. The prevailing summer breeze sweeps in from the south and south-east (Bay of Bengal). South-facing apartments capture this airflow naturally, keeping living rooms and master suites cool with minimal mechanical cooling. ### Winter Sun and Daylight During the brief winter months, the sun tracks lower along the southern sky, providing warm, gentle sunlight inside south-facing rooms. Conversely, west-facing apartments absorb scorching afternoon heat, creating a greenhouse effect that traps heat deep into the night. At Urban Haven, our architectural layouts prioritize south and south-east alignments, cross-ventilation shafts, and deep verandas to ensure optimum natural ventilation.
