Post occupancy evaluation of green building: a case study for Johor port authority’s building

Abstract

The development of green building has become a trend among the developers not only in the private sector but in the government sector as well. Green buildings are not only beneficial economically to the building owner but they also provide a conducive environment for the occupants and inflict less harm to environment. Up until September 2016, there are 715 registered green building projects in Malaysia. However, the success of green building in term of their performance is still in doubt and very much speculative. In fact, there have also been reports saying that green building fail to perform as they are intended too.Thus, there is the need to evaluate the performance of green building as it is crucial to determine whether or not they are performing as expected and what are the performance aspects that require improvement. To address this issue, Post Occupancy Evaluation (POE) on green building was conducted. Fifteen (15) performance criteria and thirty-five (35) parameters were identified from the literature and validated by green building facilitators and green building managers. Content Validity Survey was carried out resulting in the selection ofeleven (11) performance criteria and twenty-six (26) performance parameters. 120 staffs of JPA were engaged as respondents in the questionnaire survey and the data was analysed descriptively via frequency calculation. The result identified which aspects of building performance are perceived as performing and not performing well by the occupants and require attention and improvement by the Engineering Department of JPA. The findings of this research can significantly benefit JPA and the design team of the Public Work Department. This study can also be an eye-opener for Public Work Department to carry out POE for other green building projects by the government.
