Abstract
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.
