what can reduce the urban heat island effect? additional air conditioning units rooftops covered with plants
Answer
Brief Explanations:
Plants on rooftops (green roofs) can reduce the urban heat island effect. They provide shade, absorb heat through evapotranspiration, and have a cooling effect. Additional air - conditioning units generate heat as a by - product (from their operation, especially the outdoor units) and would likely contribute to the urban heat island effect rather than reduce it.
Answer:
Rooftops covered with plants.
