The Role of the Extensive Green Roofs on Decreasing Building Energy Consumption in the Mediterranean Climate
2. Materials and Methods
2.1. Case Study
- According to the ideal indoor temperature, as presented in Table 1, the use of heating or cooling has been suggested.
- The role of the heat island is not the topic of this paper and not considered in the analysis.
- Since all of the comparisons have been made for three green roofs situated in the roof of one building, therefore, the impact of the roof type under the green roof on the heat transfer between outdoor and indoor is the same, and is not considered in the analysis.
- Green roofs mostly affect the temperatures of the last and second last floors; therefore, it is not correct to refer the results to the whole building fabric, such as tall or high-rise buildings.
3. Results and Discussions
3.1. The Impact of the Green Roof on Average Roof Temperature
3.2. The Impact of the Green Roof on Indoor Heating or Cooling Period
3.3. The Monthly Average Differences between the Green Roof and Conventional Roof
3.4. The Role of Green Roof in Maximum and Minimum Roof Temperature
3.5. The Impact of Green roof Thickness, Layers, and Insulation on Roof Temperature
