Printed by Reposervice G teborg, Sweden 2016 I High-Rise Building Design A Design tool combining stakeholders and demands with Design Master s thesis in Structural Engineering and Building Technology JOHANNA RIAD Department of Applied Mechanics Division of Material and Computational Mechanics Chalmers University of Technology Abstract High-Rise buildings are becoming more common in Sweden, with several projects planned in the next few years.

3 Experience in tall Building Design is limited in Sweden, which can be problematic considering the complexity of this type of projects. There are many aspects to take into consideration, such as economy, sustainability, wind performance and vertical transportation. It is difficult to make Design changes at late project stages to adapt to aspects that have been overlooked. Therefore, early Design choices are very important in order to achieve a satisfactory Building performance. The purpose of this thesis is to provide aid in the conceptual Design process for designers with limited experience of high -rises.

4 Their understanding of the demands on High-Rise buildings and the implications Design choices have is vital. A tool incorporating key stakeholders such as residents, client and citizens and their demands gives a good general idea of High-Rise Design and the challenges it entails. To gain an understanding of High-Rise projects, a literature study was conducted and interviews were made with several stakeholders and High-Rise experts on different aspects of High-Rise Design . The nature of the information collected was analysed and a suitable way of conveying it through a Design tool was developed.

5 The Design tool is a parametric computer code programmed in Grasshopper for Rhinoceros 3D. It takes Design parameters like Building height, shape, function and slenderness as input values. It then processes the information and gives the user feedback on the Design with regards to different demands, such as daylight, economy and structural efficiency. It was found that working with a computational Design tool is a good way to give instant feedback on Design and help the designer in their process. The Design tool displays comprehensive information that is directly connected to the current Design concept, which makes the information very accessible.

6 However, creating an intuitive user interface proved a challenge. Programming the information into a tool takes time and depending on the project, modifications of the tool may be needed. The most important stakeholders, demands and Design aspects have been treated in this thesis project, and they are discussed within the report. A Design tool has been constructed and verified through a case study. Although not all features have been implemented, the results are promising and the Design tool is a working prototype that can be used as it is or as a base for further development.

8 I Sverige r erfarenheten av h ghusbyggande begr nsad och det finns m nga aspekter att ta h nsyn till som inte r relevanta i vanliga byggnader. Om man missar viktiga faktorer i ett tidigt stadie r det ofta f r sent att t nka ut ett nytt koncept n r problem v l uppt cks. I b sta fall kan man hitta en kompromiss s att byggnaden fungerar nd men i s msta fall blir resultatet s mre n man nskat. Syftet med det h r arbetet r att skapa ett designverktyg som kan anv ndas d erfarenheten av h ghusprojekt r begr nsad.

9 Genom att man f rst r de olika aspekterna av h ghusbyggande och vilka f ljder ett designbeslut f r kan man hitta ett bra koncept fr n b rjan ist llet f r att beh va kompromissa med sitt koncept i senare stadier. En litteraturstudie gjordes och intervjuer gjordes med flera olika intressenter och experter inom h ghusbyggnad. Informationen analyserades och ett l mpligt s tt att redvisa den utvecklades. Resultatet blev ett digitalt designverktyg som tar designparametrar s som byggnadens h jd och form som indata. Anv ndaren f r d refter terkoppling p den aktuella designen med analyser av bland annat dagsljus, ekonomi och byggnadssystem.

10 Att anv nda ett designverktyg visade sig vara ett bra s tt att f en verblick och f rst else f r projektet. Designverktyget visar information som r direkt sammankopplad med det aktuella konceptet, vilket g r att den blir l tt att tillg . D remot r det sv rt att skapa ett l ttf rst eligt anv ndargr nssnitt och det tar l ng tid att programmera. F r olika projekt kan olika versioner av designverktyget beh vas. De viktigaste intressenterna, kraven och designaspekterna har behandlats i det h r arbetet och de diskuteras i rapporten.
