Implication

This research finds improved shading reduces indoor temperatures in vernacular buildings, suggesting better thermal comfort solutions for sustainable development.

Key Points

  • The study aims to enhance thermal comfort in vernacular buildings in the hot arid climate of Upper Egypt.
  • Field measurements of indoor and outdoor thermal comfort
  • Evaluation of two vernacular buildings: Hassan Fathy and Nubian house
  • Simulation using ENVI-met V5.6.1 model to propose improvements for courtyards
  • Comparison of three scenarios for courtyard improvements
  • Use of adobe bricks reduced indoor temperatures by 2.7 °C to 6.7 °C compared to outdoors
  • Courtyard temperatures were 0.3 K higher than outdoor temperatures under extreme conditions
  • Integration of shaded areas with dense trees reduced PET by 4.2 °C to 5.7 °C
  • Proposed methods could enhance thermal comfort and support sustainable development in vernacular housing.
