Effects of Weather Uncertainties on the Evaluation of Building Energy Systems

As modelling enabled a better understanding and evaluation of different scenarios and circumstances of energy systems, problems of comparability and compatibility between the results and configurations came into question. The concept of Test Reference Years (TRY) has been used in energy system modelling applications as inputs to cover up these difficulties. This concept defines average and peak years, constructed as data sets for designated regions and used as weather input for energy systems. Resolving these issues, the TRY concept also brings a certain level of uncertainty, especially when it comes to building models for longer periods of time in an evaluation of an energy system. The thesis deals with historical databases after processing it to a viable structure as TRY, compares it with the reference data on a simulation model to investigate the effects of weather uncertainties on the evaluation of building energy systems.
