The role of simulation in design of high-performance buildings in Turkey

Abstract

This paper reports on an exploration of the current role of building performance simulation tools in the building and HVAC design process. The focus of the study is on the design of high-performance buildings; our hypothesis is that this is the leading edge of building design, where simulation is most likely to be used to its full potential. The methodology underlying the paper consists of surveys with architects and engineers who carried out the design of a number of high-profile buildings. The paper adds to a small body of work that, over the years, has monitored the actual role of simulation in design. Whilst a lot of work is carried out to improve the role of simulation in design, especially the early phases, the real uptake and role of the technology may not always match our expectations. Critical review of the actual role of simulation tools remains necessary to assess progress and needs for further development. Results show that simulation is regularly used in building design projects, by a range of actors. However, the use of simulation efforts seems to be mainly the confirmation of expectations and the demonstration of meeting targets, especially those that are relevant for certification schemes. Building simulation still has unused potential in terms of selection of design alternatives from extensive search or option spaces. The use of more advanced techniques such as optimization in industry remains relatively low; work on uncertainty and sensitivity is not often undertaken in practice.
