Energy performance in buildings has become one of the most broadly debated subjects in
contemporary architecture / and current legislation has emphasized its importance by requiring
buildings to possess an energy performance certificate. Due to the technological advances in
computational tools, it is possible to analyze the energy performance of buildings before construction
starts / however most energy performance evaluation tools, requiring complex solid models and high
technical knowledge in the field, can be used only during the post design phases. Since any design
decision has an important effect on the energy performance of a building, evaluation tools should be
used from the very beginning of the design process. In this dissertation, a building energy
performance evaluation program, entitled the Energy performance Advisor (EnAd), was developed for
evaluating the energy performance of buildings considering not only the legal framework of Turkey,
but also the building design process. The program does not need advanced expertise, and was
developed to be usable in any phase of the design process. The program, using the monthly
calculation method of TS EN ISO 13790, was developed based on the European Union Directive on
Energy Performance in Buildings (EPBD) and the current Turkish legislation on the subject. EnAd
integrates the legal framework with the energy performance criterion into the building design process,
while providing rapid feedback on energy performance and related legislation, and guiding the
designer to improve design decisions. This dissertation has also shown the effects of building size,
exposed surfaces, ventilation and infiltration, window-wall ratio, U-values, set-point temperatures and
temperature differences between the outside and inside spaces on energy performance of buildings
through generic case studies while searching the reasons for discrepancies between the results
derived from the four evaluation tools, three of which is highly acknowledged energy performance
evaluation tools. The validity, reliability, precision and usability of EnAd as a design-support tool has
been proved through the usability and convergence tests conducted. Finally, the thesis has pointed
out the importance of the use of energy performance evaluation tools from early stages of architectural
design process to achieve higher performances as well as the roles of decision makers in this
process.
