    Using House of Quality (HOQ) to integrate energy efficiency decision making among stakeholders of mass housing projects
    (JUNE, 2016) Quarcoo, Felix
    Design for the built environment is essentially collaborative and demands effective communication between the various stakeholders who in most cases have varying and opposing perspectives on how, when and why a building should be energy efficient. Studies indicate conflicting stakeholder requirements is a major barrier in implementing sustainability in buildings with decisions often made based on short-term economic grounds. However, the important role that different building stakeholders play in determining the type and extent of impact of building stakeholders on Building Energy Efficiency (BEE) requirement and the alignment among these stakeholders have not been accounted for in most studies. This research presents a unique investigation into evaluating the impact of different groups of stakeholder requirements on sustainable and technical aspects of building energy efficiency decisions in the mass housing sector. In this research, a House of Quality (HOQ) model was developed to synthesize the differences among the stakeholders and integrate their competing objectives to establish BEE ranking that meets stakeholder requirements in the mass housing sector. The HOQ analysis revealed that the stakeholder type in the study did not affect the ranking of their requirements, and in general, all the groups of stakeholders involved in this study did not affect the ranking of their requirements. All the stakeholders involved in this study, agreed that the primary reasons for implementing energy efficiency decision-making is based on economic grounds. The study also established that a top-down owner commitment to sustainability is needed to align the many competing stakeholder requirements and eliminate barriers that could potentially prevent efficient project decisions and results.
