Assessment of window systems considering solar and thermal performance

University essay from Lunds universitet/Energi och ByggnadsDesign

Abstract: The solar and thermal performance of window is subject to a wide range of parameters. To simulate the energy performance is therefore difficult, and limitations might occur depending on the complexity of each case. This study presents some of the current limitations related to the assessment of window considering solar and thermal performance into the policy framework (standards, regulations and certifications) and two dynamic thermal modelling (DTM) tools. It is observed that the regulations and certifications referred to various standards regarding the assessment of solar and thermal performance that could affect the results. The study concluded that for more complex constructions, the difference between the software resulted in bigger deviation among the simulation outputs. By investigating some of the limitations in the DTM tools, this study also provides possible warnings for the assessment of window.
