Green building promotion: Barriers and incentives from transaction costs perspective
B
uildings are responsible for at least 40% of energy use in most countries. The absolute figure is rising fast, as construction
booms and the rise of living standard. Urgent solution is needed to reduce buildings’ energy use, thus addressing climate
change. Reports show that with currently available technology, the energy-efficiency level could be increased by 30%, yet this
does not happen. Affordability, i.e., higher capital investment is considered as the focal concern. The affordability study often
ignores the hidden costs, i.e., transaction costs, including costs in the form of time delay, risk, stress due to the lack sufficient
information, etc. The hidden costs to different stakeholders during the green building (GB) transaction are often ignored.
Understanding these hidden transaction costs (TCs) helps appraise the costs and benefits of GB and policy effectiveness. The
example of a gross floor area (GFA) concession scheme is used systematically to explore and understand the fundamental
issues of TCs’ typology and chronology in the GB development process. The GFA concession scheme is a popular incentive due
to its indirect compensation to developers by allowing additional floor area without expenditure by government to implement
GBs. A TCs’ framework is used critically to review and evaluate the costs and benefits of the GFA concession scheme. Its
particular implementation in both Hong Kong and Singapore is explored. Hong Kong is used as a case study, complemented
with in-depth expert interviews on GFA concession in Hong Kong. The key contribution is to establish the parameters for
estimating the optimum GFA bonus that could both motivate various stakeholders and minimize the negative impacts on the
built environment in future.
