Abstract

Aging of building stock is emerging. Open Building as a sustainable approach to deal with the problems associated with the aging housing stock is seldom applied in high-rise, densely populated built environment. With aims to identify the constraints and seek rooms for Open Building implementation in aforementioned context, a survey of 495 building layout plans from ten major housing estates in Hong Kong is conducted. The floor plans are analysed against the Open Building characteristics and criteria laid down by Tiuri (1998). Facts and obstacles of achieving Open Building in the territory are unearthed, and opportunities for implementation are then discussed.

The layout and structure of the surveyed private residential buildings in Hong Kong are very much alike. They are in fact closed buildings without the capacity to adapt, so any change in user requirements cannot be accommodated easily. Implementing Open Building using flexible and green fittings remains a viable option that enables transformation in existing housing stock.

Abstract

Purpose

The purpose of this paper is to investigate the relationship between office rents and mixed-use development in the context of agglomeration economies.

Design/methodology/approach

Using a sample of 10,209 observations in 100 Grade A office buildings in Hong Kong from January 2001 to June 2011, the authors estimated office rent regression using unbalanced panel data analysis.

Findings

The results show that rents decreased with an increase in distance from retailers and hotels. Furthermore, the results revealed that, ceteris paribus, office tenants were willing to pay higher rents in a mixed-use than in a single-use office development.

Research limitations/implications

There is an existence of agglomeration economies due to the clustering of various industries in mixed-use developments, which allow for their close proximity to potential clients.

Practical implications

The diversity of activities in a mixed-use development benefit its tenants and, thus, convince them to pay higher rents. Higher rents generated by a mixed-use facility will attract more investors to it. Investors should seek opportunities to capitalize on their equity in mixed-use developments.

Originality/value

This paper attempts to uncover a relationship between office rents and mixed-use developments by drawing on the concept of agglomeration economies.

Abstract

This short paper presents the lessons learnt for conservation planning of heritage sites from a pilot study on disused military structures on Devil’s Peak, Hong Kong. Stakeholders’ interest and surveying as facilities management factors should be well considered in the planning stage for heritage conservation. Thus, public education and involvement and on‐site land surveying is essential for future project success.

Abstract

Purpose

The purpose of this study is to understand how IT capabilities for knowledge management and process integration can build a firm's agile process capabilities for sensing, strategic decision and responding. The study also investigates how the three agile capabilities affect firm performance in different competitive environments.

Design/methodology/approach

This study conducted a large-scale field survey with firms in the United States. Survey invitations were sent to business executives of the target firms. A total of 254 complete samples were collected for our hypotheses test.

Findings

The results confirm the overall significant roles of IT capabilities in the three agile capabilities. The results further reveal that the IT capability for knowledge management has a higher influence on sensing capability, while the IT capability for process integration has a higher influence on responding capability. Moreover, strategic decision and responding capabilities are more important in the high market competition. However, in the low market competition, sensing capability becomes more important while responding capability demonstrates a negative impact on firm performance.

Originality/value

This study helps both academics and practitioners better understand a firm's IT-agility-performance mechanism. Particularly, our findings guide how to achieve agile capabilities and what to focus on under the different levels of market competition.

Abstract

Purpose

The rapid growth of artificial intelligence (AI)-based voice-assistant systems (VASs) has created many opportunities for individuals to use VASs for various purposes in their daily lives. However, traditional quality success factors, such as information quality and system quality, may not be sufficient in explaining the adoption and use of AI-based VASs. This study aims to propose interaction quality as an additional, yet more important quality measure that leads to trust in an AI-based VAS and its adoption.

Design/methodology/approach

The authors propose a research model that highlights the importance of interaction quality and trust as underlying mechanisms in the adoption of AI-based VASs. Based on survey methodology and data from 221 respondents, the proposed research model is tested with a partial least squares approach.

Findings

The results suggest that interaction quality and trust are critical factors influencing the adoption of AI-based VASs. The findings also indicate that the impacts of traditional quality factors (i.e. information quality and system quality) occur through interaction quality in the context of AI-based VASs.

Originality/value

This research adds interaction quality as a new quality factor to the traditional quality factors in the information systems success model. Further, given the interactive nature of VASs, the authors use social response theory to explain the importance of the trust mechanism when individuals interact with AI-based VASs.

Abstract

Purpose

Most current additive manufacturing (AM) processes are layer based. By converting a three‐dimensional model into two‐dimensional layers, the process planning can be dramatically simplified. However, there are also drawbacks associated with such an approach such as inconsistent material properties and difficulty in embedding existing components. The purpose of this paper is to present a novel AM process that is non‐layer based and demonstrate its unique capability.

Design/methodology/approach

An AM process named computer numerically controlled (CNC) accumulation has been developed. In such a layerless AM process, a fiber optic‐cable connected with an ultraviolet (UV) LED and related lens is served as an accumulation tool. The cable is then merged inside a tank that is filled with UV‐curable liquid resin. By controlling the on/off state of the UV‐LED and the multi‐axis motion of the cable, a physical model can be built by selectively curing liquid resin into solid.

Findings

It is found that the cured resin can be safely detached from the accumulation tool by applying a Teflon coating on the tip of the fiber‐optic cable, and controlling an appropriate gap between the cable and the base. The experimental results verified the curing and attaching force models.

Research limitations/implications

A proof‐of‐concept testbed has been developed based on a curing tool that has a diameter around 2 mm. The relatively large tool size limits the geometry resolution and part quality of the built parts.

Originality/value

By incorporating multi‐axis tool motion, the CNC accumulation process can be beneficial for applications such as plastic part repairing, addition of new design features, and building around inserts.

Abstract

Purpose

The purpose of this paper is to present a mask‐image‐projection‐based stereolithography (MIP‐SL) process that can combine two base materials with various concentrations and structures to produce a solid object with desired material characteristics. Stereolithography is an additive manufacturing process in which liquid photopolymer resin is cross‐linked and converted to solid. The fabrication of digital material requires frequent resin changes during the building process. The process presented in this paper attempts to address the related challenges in achieving such fabrication capability.

Design/methodology/approach

A two‐channel system design is presented for the multi‐material MIP‐SL process. In such a design, a coated thick film and linear motions in two axes are used to reduce the separation force of a cured layer. The material cleaning approach to thoroughly remove resin residue on built surfaces is presented for the developed process. Based on a developed testbed, experimental studies were conducted to verify the effectiveness of the presented process on digital material fabrication.

Findings

The proposed two‐channel system can reduce the separation force of a cured layer by an order of magnitude in the bottom‐up projection system. The developed two‐stage cleaning approach can effectively remove resin residue on built surfaces. Several multi‐material designs have been fabricated to highlight the capability of the developed MIP‐SL process.

Research limitations/implications

A proof‐of‐concept testbed has been developed. Its building speed and accuracy can be further improved. The tests were limited to the same type of liquid resins. In addition, the removal of trapped air is a challenge in the presented process.

Originality/value

This paper presents a novel and a pioneering approach towards digital material fabrication based on the stereolithography process. This research contributes to the additive manufacturing development by significantly expanding the selection of base materials in fabricating solid objects with desired material characteristics.

Abstract

Purpose

There has been a growing public concern over the importance of building management in apartment buildings. However, people's views toward the effects of building management on building performance have long been divergent due to a lack of empirical study. This study aims to empirically test the relationship between building management regimes and the conditions of private apartment buildings in Hong Kong.

Design/methodology/approach

An assessment scheme was developed to assess the health and safety conditions of 134 apartment buildings. Multiple regression models were then applied to analyze the effect of building management regimes on building conditions. The optimal functional form of the regression models was selected using Box‐Cox transformation.

Findings

The empirical results suggested that the presence of incorporated owners and property management agents (PMA) are significant factors in enhancing building conditions.

Research limitations/implications

The sample was confined to single block buildings located in one particular district in Hong Kong. Further research is needed to validate the findings in estate‐type developments as well as those in other districts.

Practical implications

The empirical results assisted building owners in determining which management regimes to adopt should they want better building conditions. The government may also consider giving more support to owners by incorporating them and employing PMAs to create a pleasant living environment for society.

Originality/value

Our study is the first in the literature to provide an empirical test reconciling the divergent views toward the effects of building management with the conditions of buildings.

Abstract

Purpose

The purpose of this paper is to discuss a Coasian interpretation of a model of sustainable development for Hong Kong that incorporates three segments, namely economy, society, and environment.

Design/methodology/approach

The approach is analytical, using concepts of property rights informed by Coasian neo‐institutional economics and Yu's ideas on the Schumpeterian process in innovation.

Findings

First, the sustainable development criteria must be non‐dictatorial, decentralized, and compatible with market economics. The emphasis is contractarian rather than legislative or administrative. Second, the essence of segment cooperation is to create a win‐win situation rather than an “integrated” rent seeking game, which will likely result in more values being created. Third, the requirement that it be progressive over time implies that programs and policies that are duplicative need to be avoided, and innovations are to be encouraged. Fourth, the requirement of satisfying only two aspects of the three segments of cooperation implies a less stringent standard of making stepwise improvements, and thus makes entrepreneurial efforts more likely. Last, the three segments of cooperation, if practiced simultaneously and improved over time, can achieve most, if not all, the principles in the Rio Declaration without aiming at a specific principle in the Declaration.

Research limitations/implications

This paper should focus on a “win‐win” rather than a mutually exploitative approach to public participation in sustainable development promotion.

Practical implications

This paper should assist policymakers and politicians in understanding how sustainable development may be conceptually modelled.

Originality/value

The paper is the first paper that defines for Hong Kong a model of sustainable development on the basis of Coasian economics, and contrasts it with other proposed models.

The paper's objective is to empirically study the effects of building refurbishment on the prices of the dwelling units in a contiguous housing estate in Hong Kong.

Abstract

Purpose

The paper's objective is to empirically study the effects of building refurbishment on the prices of the dwelling units in a contiguous housing estate in Hong Kong.

Design/methodology/approach

In a congested living environment like Hong Kong, it is difficult, if not impossible, to have a view unobstructed by buildings. As such, the quality of views is dependent on the aesthetic quality of surrounding buildings. It is likely that poorly maintained buildings will impose negative visual effects on their immediate surroundings. Refurbishing these poor buildings should, therefore, reduce or even counter this negative externality. To study the positive externality brought about by building refurbishment, a hedonic price analysis was conducted on a set of panel data consisting of property transactions in a large housing estate located in Pokfulam. This estate was chosen because its adjoining buildings underwent refurbishment in 1998.

Findings

The results showed that the refurbishment increased significantly the prices of those properties which faced refurbished buildings, keeping other things constant. The increments, on average, amounted 6.6 per cent of the prices of the properties.

Research limitations/implications

Building refurbishment can have various scopes and scales but this study did not consider how the characteristics of the building refurbishment affected the prices of neighbourhood properties.

Practical implications

Given the problems of aging buildings in most urban areas, the results presented significant practical implications for building refurbishment and urban renewal as a whole. Developers or property owners may be lured to invest in the refurbishment of adjacent dilapidated properties with a view to enhancing the values of their own properties.

Originality/value

Although previous studies analytically suggested that building refurbishment created positive externality, this study is the first attempt to explore this connection.
