2.5.2 PHASE 2 - IDENTIFICATION POINTS OF INTERESTThe second phase of this research has two goals. The first goal is the identification andevaluation of factors of influence on the performance of sustainable renovation concepts.The second goal is the identification and analysis of factors of influence for the marketimplementation of innovative sustainable renovation concepts.IDENTIFICATION OF FACTORS OF INFLUENCEFor identify factors of influence on the performance of sustainable renovation concepts,existing evaluation models in the field of sustainability are analyzed and evaluated. Also,expert interviews are executed.SELECTION OF MODELSExisting sustainability assessment models are analyzed to identify factors that influencethe performance of sustainable renovation concepts. For the selection of analyzedmodels, the following selection criteria are defined:The existing model must be:- applied on large scale in the Netherlands- able to provide objective information- up-to-date- developed by a specialized agencyAs a result of these selection criteria, four models that are currently used for thedetermination of the sustainable performance of buildings are selected and analyzed.These models are listed in figure 8.ModelEPWBREEAMGPR GebouwGreencalcFIGURE 8 - ANALYZED MODELSDeveloped byDGMRBuilding Research Establishment (UK)W/E AdviseursSureacThe results of this model evaluation are provided in paragraph 3.4, page 36.SELECTION OF EXPERTSNext to the analysis of these four models, expert interviews are executed to create acomprising view on the factors that have an influence on the performance of sustainablerenovation concepts. For the selection of experts that are interviewed in this phase, thefollowing selection criteria are defined:The respondent must be:- a specialist on at least one of the factors that influence the performance ofsustainable renovation concepts. These factors of influence are: life cycle costs, lifecycle yields, environmental impact, quality, and energy performance- willing to share his/her knowledge, so that it can be used for this research- able to provide objective informationAs a result of the selection criteria stated above, seven experts are interviewed to gatherinput for the development of the model. Appendix A describes why these respondents areselected for an interview. Appendix B provides a list with the seven selected experts.The executed interviews were structured on the basis of a questionnaire, which iselaborated in advance of the interviews. The questionnaires concern general questionsabout relevant subjects and specific questions that are specified on the expertise and16
profession of the expert. The notes and results of these interviews are provided inappendix B.MARKET IMPLEMENTATIONThe second goal of this phase is the identification of factors that influence the marketimplementation of innovative sustainable renovation concepts. Therefore, a literaturestudy and expert interviews are executed. The results of the executed literature studyand interviews are provided in paragraph 3.1, page 20.LITERATURE STUDYThe literature study is performed to identify factors that influence the marketimplementation of innovative sustainable renovation concepts. Therefore, informationfrom websites, scientific articles, and scientific reports is used.SELECTION OF EXPERTSThe goal of the interviews with involved experts at the renovation project “De Tempel” isto identify barriers for the practical execution of the renovation concept and to identifyfactors that influence the practical execution of the WarmBouwen concept. To create acomprising view, experts that are involved as representative of different stakeholders atthe execution process of project “De Tempel” are interviewed. As a result of the goalstated above, three experts are selected and interviewed. Appendix B provides a list withthe selected experts.The executed interviews are structured on the basis of a questionnaire, which iselaborated in advance of the interviews. This questionnaire is specified on the expertiseand profession of the expert. The notes of these interviews are provided in appendix B.The result of the second phase of this research is a first version of the performanceevaluation model for sustainable renovation concepts. This concept model is presented infigure 17, page 31. In the model development process, information from the literaturestudy is compared with results from the expert interviews. The factors with an influenceon the performance of renovation concepts are integrated into one model.2.5.3 PHASE 3 - MODEL DEVELOPMENTIn the third phase, the results from the literature study, existing model evaluations, andexpert interviews are compared and evaluated. This phase results in the development ofthe final “performance evaluation model for sustainable renovation concepts”, which isdepicted and explained in more detail in chapter 4, page 45.2.5.4 PHASE 4 - MODEL TESTING AND OPTIMIZATIONIn the fourth phase, the applicability and completeness of the model and its integratedfactors are evaluated. This is done by applying the developed model on three selectedrenovation alternatives. For the determination of input parameters for this process, aliterature study, case studies, and expert consults are executed. The second goal of thisphase is the improvement and optimization of the model, based on insights from themodel application.MODEL TESTINGFor the application of the model, three alternatives for the renovation of a house areselected. One of the selected renovation alternatives is the WarmBouwen concept,because this is the renovation concept that is evaluated in this research. Chapter 5, page58 provides detailed information about the WarmBouwen concept. For the selection ofthe other alternatives the following criteria are defined.17
