The primary cause of the heat island effect is dark surfaces such as rooftops or dark asphalt pavement that absorb heat and radiate it into the surrounding areas.

Reduced air flow between buildings and narrow streets also increases the effect.
Passive ventilation impacts energy use but would not increase the heat island effect.

Other causes of the heat island effect include air-conditioners, vehicle exhaust, and calm and sunny weather.

High SRI materials with reflect the heat rather than absorb it and radiate the heat back later on.
