Abstract

The quality of teaching and learning activities is a key indicator of success in formal education, and the provision of comfortable classrooms plays a vital role in supporting optimal learning outcomes. This community service aimed to analyze and improve the thermal comfort of the proposed classroom design at MTs Ummu Aiman Malang, ensuring that the building meets thermal comfort standards and regulations. A 3D model of the school building was developed, and a Computational Fluid Dynamics (CFD) simulation was employed to assess indoor air distribution and airflow. Based on the theoretical analysis and simulations conducted, some alternative design optimizations suggested are choosing the color of the exterior wall paint with a light color gradation that has a good heat absorption value, using a type of double-glaze glass that has better thermal performance, adding heat insulation material to the exterior walls of the east and west sides, and modifying the opening of the window to maximize natural ventilation and improve air circulation in the classroom. By optimizing the design, the OTTV value of the MTS Ummu Aiman building was reduced from 97.07 W/m² to 33.49 W/m². In addition, the addition of openings in the window changes the temperature range in the classroom, which was previously 26.6 -29.3 °C, to a temperature range of 22.8-25.8 °C, with the air velocity falling above the occupants' heads not exceeding 0.25 m/s. The results demonstrate that design optimization and appropriate material selection significantly improve thermal comfort and energy efficiency, providing a practical reference for sustainable school building design.
