Buildings account for 39% of emission worldwide. The study aims to clarify the effects of thermal insulation materials used in West Bank Palestinian buildings, to demonstrate their capacity to reduce emissions and saving cost. Using a variety of records from the Engineers Syndicate and the Palestinian Central Bureau of Statistics, a thorough study of buildings in the West Bank area was carried out to determine the number and area of buildings. Additionally, data from sources of energy was collected for the study years 2018–2021. Following the use of thermal insulation materials to the buildings, computations were then equipped with thermal insulation materials, and calculations to estimate the energy savings and reductions in carbon dioxide (CO₂) emissions. The results show, using insulating materials reduce energy consumption by 27.23% and CO₂ emissions significantly. It is anticipated that the cost recovery period for new construction is 0.39 to 1.09 years, and for repaired buildings it is between 4.34 and 7.2 years. Depending on the location and typical temperature of the area. The study recommends working for the widespread use of insulating materials in all new construction and for retrofitting existing structures. These initiatives will support international efforts to reduce emissions and achieve sustainable development goals in addition to improving energy efficiency.
