Improving the Thermal Performance of Building Envelopes: An Approach to Enhancing the Building Energy Efficiency Code

Cities on the east Mediterranean coast, especially in Palestine, are struggling to move towards sustainability as they vulnerable climate change and lack natural resources, energy this situation is further aggravated by high prices. The problem building sector, which most challenging sector when it comes cities’ and, specifically, sustainability. In main consumer of but lacks efficiency measures, such up-to-date codes. This study analyzed thermal performance under different scenarios with a focus envelopes. We aimed evaluate benefits introducing an updated code—mainly addressing U-values for envelopes—on future reductions demand. used simulation tool (DesignBuilder) typical existing building-envelope performances. Then, we undertook comparison between conditions proposed application scenarios, including Palestinian code green guidelines, ASHRAE envelopes, Jordanian code, order introduce envelope code. results showed that current situation—building without applying any or code—is far from high-energy could be achieved international local use insulation reduce demand heating 83 43%, depending type, climatic zone, U-value. recommend utilizing envelopes zones achieve performance. have implications construction industry professionals, governments, researchers seeking establish high-energy-performance
