A dynamic sky recognition method for use in energy efficient lighting design based on CIE standard general skies

This paper innovatively proposes an “active green lighting model” for control and optimization of building luminous environment. It is expected to optimize the utilization of daylight dynamically in energy efficient lighting design from the viewpoint of intelligent control. As one primary work of implementing the overall model, the luminance distribution of CIE standard general Skies is addressed, and a dynamic sky recognition method for utilization optimization of daylight is proposed based on swarm intelligence. The experiment results of instance field data show the proposed intelligent sky recognition method is feasible and effective.

Management contracting in Hong Kong

Despite technological advancement in building techniques, new construction tools, equipment, and plant, and a greater variety and better quality of construction materials, the construction industry is generally regarded as one making slow progress in productivity. Here the potential of management contracting as a contracting method is considered in depth. Analysis includes assessment of its fundamental features, cost-benefit analysis and practical applications. The feasibility of its adoption in Hong Kong is evaluated.     

Private Rental Housing in Hong Kong

This paper examines selected aspects of housing policy and its influence on private rental housing in Hong Kong. Its ambitions are modest, in part because so little research has been conducted on the sector, as a consequence of the small size of the sector as well as the concentration of socio-political, economic and policy analyses on the other major housing sectors, namely public renting and home ownership. It is argued that a fundamental function of private renting, to provide a functional substitute and counter-balance to distortions in the market for private home ownership, has been systematically undermined in Hong Kong. In spite of its historical importance in meeting Hong Kong people's housing needs, the sector's decline has been steep and it can now be fairly described as a marginalised tenure, despite incomplete structural adjustment post- Asian Financial Crisis. It is suggested that a fundamental reason for the decline of the private rental sector has been the impact of government policy, which undermined the private rental sector and thus an important element of the market mechanism in housing provision. The government's ideology of home ownership has also functioned to transfer lower middle-income families into the owner occupied sector. Although the Hong Kong government has not been as overtly hostile to this sector as governments have been elsewhere, it nevertheless also seems to envisage no real role for the private rental sector in a housing delivery system molded by policy preference for home ownership, rather than fostering viable economic competition by also facilitating an efficient private rental sector.

港岛城市剖面

文章借用建筑学上的剖面概念,将其应用到城市尺度的形态分析和空间解读上。作者选取香港中环地区的中环至半山由自动扶梯系统覆盖的城市区域,作为诠释这一概念的具体案例。建筑剖面的传统意义被移植至城市剖面中,即在某一方向上剖切实体之后,通过观察剖切面上空间元素之间的关系,探寻彼此的内在结构,乃至这种城市结构空间背后的特殊历史过程和社会推力。香港岛的地理特征和100多年来城市化过程所形成的带状城市分布使得港岛具有剖面性格,而中环至半山的自动扶梯系统提供了一条重要的剖切线索。通过剖面方法解析,作者希望在城市形态学的分析方法上有新的突破。

Market structure of the construction industry in Hong Kong

This study examines the market structure of four different sectors within the construction industry in Hong Kong. Market concentrations, expressed in terms of Herfindahl-Hershamann indices (HHIs) and number equivalents (HNEs), are calibrated for the top five contractors and compared with those of the local property industry. The study reveals the following ascending order of market concentrations: private building, public building, property development, and civil engineering. Our explanation is that technological and capital requirements have imposed a strong barrier to entry into the civil engineering sector, resulting in a concentrated market. Conversely, the lack of technological demand and supply in the private building sector has led to easy market entry and exit. Building contractors thus compete intensely on cost reduction rather than technology improvement, leading to poor construction safety and product quality. The paper concludes that the Government, being a major client of construction works and regulator of the industry, can assume a more active role in promoting the overall competitiveness of indigenous local contractors in Hong Kong.     

A survey of building envelope designs for commercial buildings in Hong Kong

Nearly 1 million m² of gross floor area is represented by the survey which identified four different building envelope designs. To enable judgements to be made on construction cost and time, a comparative study was carried out based on a 40-storey generic office building.     

Factors affecting clients' project dispute resolution satisfaction in Hong Kong

The use of project dispute resolution satisfaction (DRS) as a project success measurement responds to the increasing concern over the spread of the dispute epidemic within the construction industry in Hong Kong. The DRS of a project is considered as favourable where disputes are resolved within the site level. With the use of 48 project data sets and the technique of multivariate discriminant analysis, a discriminant model function was derived to classify projects into favourable DRS and adverse DRS. The multivariate discriminant analysis model function identified eight discriminating variables, among which the degree of design changes offered the highest separation power. The reliability of the discrminating variables was reinforced by a separate relative importance index study. Through the use of principal component factor analysis, these variables were grouped into three factors generically described as substantive influence, facilitation and indirect influence.     

Hong Kong Labyrinths

In this set of film stills, Soki So recasts the tangled density of Hong Kong's high-rises as Piranesi's ‘Carceri’. It is a hyper-realism that magnifies and intensifies the urban experience, highlighting the precariousness of current environmental and social conditions.

Conflict management styles in Hong Kong industries

Review of literature has revealed that little research on conflict management has been conducted in Hong Kong industries despite Hong Kong being one of the world's most competitive economies, and a major commercial, financial, industrial centre. This paper examines the use of different conflict resolutions in 63 actual case studies from Hong Kong industries. Contrary to common perception and previous findings, ‘confrontation', as a mode of conflict resolution, is found to be more commonly used in handling conflict. And significantly, almost all of the case incidents which used the ‘confrontation' approach were said to have achieved positive consequences. The authors argue that this change of resolution strategy in the past decade could be due to the increasing number of Hong Kong companies adopting the matrix structure explicitly or implicitly in carrying their projects. It appears that in Hong Kong industries, the influence of the Chinese culture and traditional values in attitude, behaviour and professional practices of both engineers as well as managers, is diminishing. Although the ‘withdrawal' and ‘forcing' approaches were also being used for certain types of conflict, as revealed by some of the case studies, the consequences are often recognised to be dysfunctional to team work.
