Good morning, everyone. Today, I'd like to continue our discussion on urban planning by focusing on the concept of 'green roofs'. As you may know, green roofs are rooftops covered with vegetation. They offer several benefits, such as reducing stormwater runoff and improving air quality. However, one key advantage that is often overlooked is their role in energy conservation. By providing natural insulation, green roofs can significantly reduce the need for heating in winter and cooling in summer, leading to lower energy bills. A study in Toronto found that buildings with green roofs experienced up to a 25% reduction in energy consumption compared to conventional roofs. This makes them a cost-effective solution in the long term, despite higher initial installation costs.
