In which area of a building can green roofs be installed for natural insulation?a) Basementsb) Atticsc) Roofsd) Walls

Understanding Green Roofs

Green roofs are vegetative layers grown on rooftops that act as natural insulation and help with energy efficiency. They typically consist of a waterproofing membrane, a drainage system, soil, and vegetation.

Analyzing Options

1. Basements: Green roofs are not installed in basements. They require exposure to sunlight for the vegetation.
2. Attics: While some insulation can occur in attics, green roofs are specifically designed for horizontal surfaces exposed to the elements.
3. Roofs: This is the most common area for green roofs. They provide effective insulation and help in temperature regulation.
4. Walls: Green walls (or vertical gardens) exist, but they are not referred to as green roofs and do not function the same way for insulation.

Conclusion

Green roofs are specifically designed to be installed on roofs, making option c) Roofs the correct answer. This area allows for the best implementation of natural insulation through the plant layers.
