The main purpose of the present thesis was to evaluate simplified models intended for checking compliance with Danish Building Regulations regarding summer thermal comfort.

A survey among companies initially specifies the necessity of a simplified in the preliminary design phase in order to predict how a building design will influence of risk of overheating in residential buildings. A simplified model developed by the Danish Building Research Institute intended for such preliminary estimation and for checking compliance with Danish building Regulations has been evaluated. Prior to the evaluation of this simplified model two additional methods to predict excessive operative temperatures in building are compared according to their implementation and usage of boundary conditions and input data. Thanks to sensitivity analysis the most important input parameters was revealed which made it possible to focus on improvements and select the most favourable boundary conditions.

Subsequently, by implementing similar boundary conditions and input data for each of the considered simplified models an evaluation solely based on model calculation procedures was conducted by usage of changing input parameters and consider their impact in model output. In the end simplified models varying by difference in level of complexity in user input and calculation procedure are evaluated based on aspects of quality. This is based on five real buildings.
