Double skin facades (DSFs) and phase change materials (PCMs) are promising ways to reduce the energy demand of buildings. In this work, the effects of glazing type considering the orientation of the building on its energy performance have been studied. A four-story office building in Valencia, Spain, has been selected as the case study and has been simulated using EnergyPlus software. The materials for the building envelope for the base case study were selected considering the new Spanish code CTE-DB-HE 2019, which classifies Valencia in the B3 climate zone. The heating load was minimum when the DSF was facing south, while the minimum cooling load occurred when the DSF was facing north. Annual energy consumption reached its lowest value when the DSF was facing north. PCM was applied to different wall layers, finding that PCM located in the most inner layer performed better than in the other layers.
