Strategies for achieving thermal comfort represent a crucial cornerstone of sustainable indoor architectural design, focusing on delivering comfortable environments without over-relying on mechanical HVAC systems. These design solutions rely on optimal building orientation, leveraging natural ventilation, optimizing daylighting, and selecting construction materials with high thermal mass and superior insulation. Additionally, incorporating external shading, water features, and vegetation helps regulate indoor temperatures, significantly reducing energy consumption. Academic research demonstrates that integrating these passive design solutions substantially enhances the environmental efficiency of buildings while promoting human health and well-being within architectural spaces.
