The prioritisation and satisfaction on Thai’s Rating of Energy and Environmental Sustainability criteria

Abstract

PurposeThe environmental performance of buildings can be measured by using an existing green building indicator system. In Thailand, the Thai’s Rating of Energy and Environmental Sustainability (TREES) has been applied to 70 buildings including condominiums. It is important to collect feedback from stakeholders to identify the criteria of green features that respond to the expectation of condominium’s potential buyers as well as the satisfaction of current occupants. This paper aims to examine prioritised aspects from potential buyers and occupant satisfaction of the TREES criteria in the case study, a green condominium in Bangkok, Thailand.Design/methodology/approachThe case study was conducted at IDEO Mobi Sathorn in Bangkok, the only condominium certified with the TREES system so far. Research methods include interviews, observations, document analysis and the surveys from the condominium’s potential buyers and current occupants.FindingsThe findings indicate that the condominium’s potential buyers are more concerned about site and landscape, indoor environmental quality and energy and atmosphere, whereas the current occupants are more satisfied about water conservation, site and landscape and energy and atmosphere in comparison with the other TREES criteria. Despite the provision of green features in the condominium, occupants are less satisfied about green innovation as showed in the least satisfied percentage of TREES criteria. In Facilities Management perspective, the paper shows connections between TREES criteria and FM functions in multi-unit residential project. The findings show that the application of TREES criteria focuses on the provision of value in FM, whereas stakeholder perceptions regarding the TREES criteria contribute to the perception of value in FM.Practical implicationsThe findings and reflections upon the finding can help to understand the impact of green building aspects of the TREES system on perceptions of different stakeholders, that is, potential buyers and current occupants of the condominium. Recommendations for real estate developers and facilities managers regarding the development of green building concept on the TREES system are provided.Originality/valueThere has been no prior research in this area. The paper provides better understanding with regard to prioritised aspects from the potential buyers and occupant satisfaction of TREES criteria in Bangkok green condominium. This paper provides empirical data regarding stakeholder perception on TREES criteria that can be used to compare with similar data of the TREES-certified condominiums when they are available in the future.
