Limitation of Study LITERATURE REVIEW

131 been used for this study which is a simulated model, not a real one to ascertain the applicability to the real world.

3.6 Summary

In this chapter, the case study research methodology with sequential mixed-method for data collection was explained as the design of this study. Regarding the stated problem, the selected methodology for this research was qualitative. Based on the research question, case study was chosen as the general approach for this research. Then, according to Yin 2003, case study components were explained. Furthermore, for linking the collected data to the research propositions, this study used a sequential mix method. In fact, to answer the first and second sub-RQs, the case study was employed. Answering the first two research questions will lead to proposing a knowledge-base framework for the conceptual design phase. Evaluation of the proposed knowledge-based framework is performed through the simulation process using computational modeling using Simvision. Moreover, according to Yin 2003, four validation steps construct validity, internal validity, external validity and reliability for case study were explained. 132 CHAPTER 4 RESULT AND ANALYSIS

4.1 Introduction

In this chapter, the data obtained through the case study is explained and analyzed. In the procedure of data collection, the primary method was observation during the conceptual design phase of a Green building project for Institiut Teknologi Maju ITMA. The purpose here was to identify the required mechanicalelectrical knowledge for being considered during this stage. Then, the observation method and also observation protocol are explained. Later in this chapter, observation results elicited from the video records are elaborated. Next step will be to compare the collected data with existing standards for fundamental mechanicalelectrical requirements and Green Building Index. Finally, in view of detailed definitions for activities of Macmillan framework for conceptual design phase, the required mechanicalelectrical knowledge is assigned to the activities of this framework.
