Urban Heat Island
Role : Client: Fosters + Partners
Team : Pranati Yadav
Role: Problem analyser and Conceptualisation
Brief
Proposing interventions tackling Urban Heat Island, effect within the context of Delhi.
What is UHI?
A phenomenon whereby cities experience higher air temperatures than the surrounding countryside.
Cause
-
Increasing urban structure concentration
-
less greenery
Heat unable to escape , hence increase in temperature.
Refining context - slums
Nearly half of Delhi’s population are living in the slums. 675 slum clusters, home to around 15.5 lakh people.
Problem Identification
​​
-
Infrastructurally dense housing
-
Use of heat conducting materials
-
Proximity to Industrial area
-
Limited living space and cooking inside house
Concept
​​
Create a transformative solution by utilising the existing construction materials which is being used in the present and manipulate them with new easily available materials to create a more effective heat resistant mechanism.
​
Every human being regardless of their income or social status deserves a safe living environment. The space we live directly affects our lifestyle. Creating a healthy space for a healthy life.

For Summer
​​
Enhanced Insulation: Double walls create an air gap between the inner and outer layers, acting as a natural insulator. This can significantly reduce heat transfer into the dwelling during hot days, keeping the interior cooler.
​
Improved Ventilation: The gap between the walls can be used to create natural ventilation channels and hot air can be drawn out from the inner wall, promoting air circulation and cooling.
For Winter​​
Reduced Heat Loss: The air gap acts as a barrier, preventing heat from escaping the inner wall and keeping the dwelling warmer during cold nights.
​
Wind Protection: Double walls provide additional insulation against cold winds, reducing heat loss and drafts.
​
Potential for Heating Integration: The air gap enables passive solar heating systems. It traps warm air from south-facing windows. The inner wall can be heated naturally during sunny winter days.
