    A projective study of blended synchronous learning for property education in the COVID-19 pandemic
    Cheung, KL ; Wu, H (Pacific Rim Real Estate Society, 2022-01-31)
    The outbreak of COVID-19 has brought serious disruptions worldwide and higher education sector has been at the forefront of this global pandemic which demands innovative responses. This paper explores blended synchronous learning (BSL) as an approach available to cope with the unprecedented pandemic destruction to teaching-learning in higher education sector. To adapt to the “new normal” and try to mitigate pandemic physical and social distancing, new technology is valued option to combine face-to-face and remote teaching-learning activities, and BSL forms part of this experiment. This paper presents a review of literature on the BSL and examines its applications in property courses in Australia as an example. It illustrates the role and value of BSL as a novel teaching-learning mode valuable during and beyond the pandemic period.

    A Project-Based Learning Approach To Support Green Building Education
    Hou, H ; Wu, H ; Lai, J (Pacific Rim Real Estate Society, 2022-01-31)
    This paper presents the design, implementation and evaluation result of a project-based learning-led hospitality real estate management course of a master programme in Hong Kong. In order to raise students’ environmental awareness, the course was designed based on a pedagogical model that incorporates four types of teaching methods to support project-based learning. In this course, students are allowed to attend lecturebased teaching, a virtual site visit to the CIC-Zero Carbon Park, a physical site visit to a green hotel, followed by accomplishing a practicum-based project. To measure the effectiveness of the course delivery, feedbacks from both green building professionals and the students of the course were collected. The analysed results reveal that the course was able to cover the intended green building lifecycle knowledge and provided the students with positive learning experience; furthermore, the dynamic structure of the course enhanced the students’ interest in fostering green buildings.

    Concept and barriers for the economic value of low-energy houses
    Wu, H ; Crawford, RH ; Warren-Myers, G ; Dave, M ; Noguchi, M (Royal Institution of Chartered Surveyors, 2015)
    This study explores the market revealed price of low-energy residential buildings and why the economic value of low-energy housing products is less transparent in active residential markets. It explores Australian and Japanese conditions and examines the proposition by using embodied energy, operational energy and market price data of selected housing stock in Australia. The study aims to examine a new perspective towards understanding the barriers to ascertaining the economic value of low-energy buildings. In particular, the study examines the composition of energy consumption associated with the residential property life cycle. Operational energy is linked to consumer preference by its inter-temporal value estimate of future expected utility or benefit flow. A ‘low’ embodied energy house is an environmental construct, which does not appear to currently link to short-term market value perception. It does not strongly link to an expected (intuitive) benefit. This ‘gap/disconnect’ creates a barrier to estimating a holistic economic value of low-energy residential property.

    Community’s Interest in Brownfield Development: A Case in Melbourne
    Li, X ; Wu, H ; Hou, HC ; Lu, X ; Lu, W ; Zhang, Z ; Peng, Y (Springer, 2021)
    Brownfield developments may be theoretically and practically approached as the method and process to convert previous industrial land with environmental concern that mitigates problem occurs in the urbanisation processes. Given rapid urban growth and land supply constraint, urban brownfield is becoming attractive to developers and local government. Along with research focus on developer and planner’s perspectives, this paper investigates local community’s involvement in and its impact on brownfield developments. Local community suffers cost and risk associate with brownfield development which can be easily discounted or even ignored in development phases. It is important to understand community’s concerns, involvement and impacts. A brownfield project from Melbourne is studied by questionnaire surveys and face-to-face interviews. The local community confirms their awareness of the project although their involvement is low because many claimed their lack of in-depth knowledge of project effects. Obstructions and lack of motivation at local community level in brownfield development impose policy challenge and social risk.

    Digital twin to enable smart heritage facilities management: a systematic literature review
    Hou, HC ; Remöy, H ; Wu, H (Pacific Rim Real Estate Society (PRRES), 2021-02-04)
    This paper aims to investigate theoretical and practical links between applications of digital twin (DT) and heritage facilities management (HFM) in order to identify future applications of DT in HFM through a systematic review of the rapidly expanding DT literature. A systematic literature review strategy was developed based on three research questions: what are (1) the current relationship between ID and HFM, (2) existing gaps between DT and HFM and (3) future trend of applying DT on BHM? The results of the literature review show that first, the studies on adopting DT in the disciplines architecture, engineering, construction and operation (AECO) have been growing in the past few years, especially from 2018 to 2020; second, among the identified papers, a major portion of the literature focuses on investigating DT’s application in maintenance, operation, facilities management and asset management from both the building level and smart city level; third, heritage conservation calls for digital solutions for problems related to performance monitoring and predictive maintenance. The implication of this study is that DT application in HFM is that DT shall be integrated with heritage building information modelling (HBIM) to facilitate efficient data management and HBIM-based mechanism for DT development is needed for future HFM.

    An investigation of private-owner-led heritage property adaptive reuse
    Wu, H ; Hou, HC (Pacific Rim Real Estate Society (PRRES), 2021-02-04)
    This paper provides a new approach to examine privately-owned heritage property for their adaptive reuse. Two cases from Tasmania and Hong Kong were investigated. Private owners’ roles in adaptive reuse of property while effectively conserving heritage values is evaluated for their incentives and costs in the course of adaptive reuse innovation. Details from the two cases from different jurisdictions reveal: first, private ownership may allow higher degree of innovation in heritage building adaptive reuse. Second, the private property owner is entitled to stronger control of the heritage property’s use. However, privately owned heritage property does not guarantee free will in transforming heritage value; the process may incur extra social cost when the owner tends to pursue her own interest that needs be self-enforced. Thirdly, the control right over heritage buildings conservation and transformation vary by their adaptive reuse conservation strategies. For example, business operation (the Hobart case) and owner public use (the Hong Kong case). This study contributes insights to the adaptive innovations in the context of privately-owned heritage properties.

    Environmental Concern, Green Purchase Intention and Customers' Perceived Green Building Design
    Hou, H ; Wu, H (Pacific Rim Real Estate Society (PRRES), 2020-01-22)
    Past research suggests a number of behavioural factors positively affect customers’ decision on staying in a green hotel. The effect of environmental attitude or environmental concern on green purchase decision is widely researched, but there are also research that reveals a certain degree of inconsistency of the relationship between consumer attitude and purchase decision. This paper puts this concern in the context of the hospitality industry. It investigates the effects of customers’ environmental concern (EC) on their intention of staying (IoS) in a green hotel and the moderating effect that the customers’ perceived importance of green building design (PIGBD) may have on their IoS in a green hotel. A measurement scale of PIBD is developed based on a local green building certification scheme (HKBEAM PLUS) in Hong Kong and a survey of 166 hotel customers in Hong Kong was conducted. The regression-based statistical results show that both EC and PIGBD have a positive effect on IoS, and PIBA appears to be a moderator on the relationship between EC and IoS. Other findings include that customers of different age / gender / education groups do not differ significantly in their environmental concern. The findings of this study give useful implication for green hotel development and management in the future. We believe that hotel customers’ understanding of green building can be enhanced through a hotel marketing strategy and a comprehensive integration of green attributes in building design.

    Housing for elderly in cross culture context
    Wu, H ; Hou, H (Pacific Rim Real Estate Society (PRRES), 2020-01-22)
    This paper concerns different contexts of elderly housing and its provision basing on the premise that, similar to other socially-disadvantaged, the elderly needs such social support as subsidy and direct aid due to their declining decision-making power and physical ability. Elderly housing is by and large a social support scheme jointly supplied by various sectors. This paper raises the question whether market arrangement is capable of supplementing social services of elderly housing in absence of efficient institutions? It adopts a comparative case approach to confronting the important concern that cities are distinctive by their institutional conditions for elderly housing provision. We select three international cities and compare their elderly housing policies and provision. We found that elderly housing in different cities exhibits its unique structural features. Given continuous aging population, the market-driven segment may be a valid substitute of the state-driven services. And this creates stratification of the life-style retirement village sub-market and the government intervened and regulated aged care facilities sector.
