The Challenge
The Leh Assembly building sits above 3,500 metres where winter temperatures drop severely and conventional heating systems struggle with efficiency and reliability.
As a retrofit project, routing new infrastructure through an existing institutional structure required careful coordination to minimise disruption while meeting strict performance targets.
High-altitude conditions demand robust equipment selection, precise borehole design and ventilation strategies adapted to low humidity and cold extremes.
