GLOBAL AND DIFFUSE ILLUMINANCE DATA IN\ud MAKASSAR-INDONESIA

In an effort to join and participate in international daylight measurement program (IDMP)\ud and collect data in the tropics, a measurement stations which measured the daylight and\ud solar radiation data have been established in Makassar and has been operating since 1995\ud until 2000. Furthermore, measurement data to global illuminance (Evg) and diffuse\ud illuminance (Evd) have been resumed from April to October 2010.\ud Data processing begins with the daily data tabulated in intervals of 15 minutes each day\ud comes with a chart of daily data fluctuations.\ud The results obtained by the number of quality control for the Evg data 99.99% of the total\ud data recorded. The results of quality control data 100% of the total data recorded. The result\ud of quality control comparison between Evg and Evd shows the result of 93.44% of the data\ud that pass quality control.\ud The result of measurement of Evg and Evd held in Makassar in 2010 is a qualified data and\ud valid for further analysis under guidelines of the CIE-IDMP. The results of the data\ud tabulation and daily fluctuation graphs are intended for ease of comparison and analysis\ud and preparation of data exchange, nationally and internationally

Daylight Measurement Data in Makassar-Indonesia

Daylight and solar radiation data are important parts of building design, especially for energy efficient building design. However, many of fundamental daylight and solar research studies used by architects are based upon data taken in other parts of the world. In order to investigate daylight availability data in tropic area which are extremely lacking at the present stage, a station has been established in Makassar. The station collects the following data: global illuminance/irradiance, diffuse horizontal illuminance/irradiance, and sunshine duration. This paper shows the details of the measurement station, data acquisition and processing, quality control, and example of collected daylight data

Compromising building regulations and user expectations in the design of high-rise domestic kitchens

Purpose ??? The purpose of this paper is to discuss the significance and relevance of social and habitual behaviours of home occupants to the building design process. It argues that introducing quantitative measures such as daylight level alone may not result in a ???healthy and functional??? kitchen without appreciating or factoring-in the impacts of the social roles and user expectations of kitchens in high-rise and compact urban situations.\ud Design/methodology/approach ??? The study investigated three common types of apartment buildings in Hong Kong. Case studies suggested that it is crucial to include in a design process proper considerations of human behaviours byway of preferred approaches andmodes of living, space usage, and weightings of end-user responses that would influence architectural design in a direct and crucial way.\ud Findings ??? The study noted that daylight quality of a kitchen is perceived by most families to be not as important as building control officials and designers thought it would. Instead, it is found that social and cultural factors are more important parameters for users. The study observed that designers rely on physical and quantitative approaches such as daylight factor, window size and window-to-room area ratio to qualify a design solution and ignore the socio-cultural parameters.\ud Originality/value ??? The paper calls for designers and building control officials to incorporate the study of functionality and socio-cultural preferences of users groups in the building design process. The study envisages that an integrated design methodology would enhance the living environment

Daylight availability in Hong Kong: classification into three sky conditions

A preliminary analysis of daylight data in Hong Kong was carried out. This analysis classified daylight data into three sky conditions\ud ??? clear, intermediate and overcast ??? using two methods, that is, sunshine duration and cloud ratio methods. It was\ud carried out based on data measured at the daylight station located in the University of Hong Kong main campus, which\ud was collected during October 2006 to September 2007. The probabilities of the occurrence of the three sky conditions\ud were 3.78% (clear), 67.10% (intermediate), 29.11% (overcast) and 4.78% (clear), 65.17% (intermediate), 30.34% (overcast)\ud using sunshine duration and cloud ratio methods, respectively. The statistical analysis t-test showed that the two sets of probabilities\ud were the same. It was also found that a global and diffuse horizontal illuminance of more than 10klux was available\ud 85% of the time, which indicated that daylight illuminance was sufficiently available in the unobstructed sky of Hong Kong

The Performance of Anidolic Daylighting System for Tall Buildings in Densely Built Cities under Overcast Sky

This paper aims to analyze the performance of Anidolic day-lighting system in the improving of daylight\ud performance, as well as contributing towards energy saving due to lighting usage in tall residential buildings\ud found popular in densely built cities such as Hong Kong. Two cases i.e. Base Case and Anidolic system have been\ud measured under real overcast sky condition in the real context. The results show that the anidolic daylighting system\ud significantly improved the daylight factor (DF) by 26% at rear room, increased daylight uniformity by 17%, and\ud reduced lighting energy use by 25% in comparison to the Base Case. However, further study in the real situation by\ud mock-up method is needed to test the real daylight performance of this system. The authors believe that the actual\ud performance of Anidolic system would be better than the simulated and the scale model ones

Policies for implementing multiple intensive land use in Hong Kong

The entire Hong Kong SAR acts as a network of primary, secondary and tertiary Multiple Intensive Land Use (MILU) zones linked by relatively cheap and speedy public transport. The MILU forms of Hong Kong have been developed as an efficient design response within a small city-state to population growth and shortages of buildable land. However, planning guidelines and development control instruments and policies have promoted public and private sector cooperation and achieved a high degree of integration of residential, commercial and other uses. This paper discusses the design approaches in Hong Kong and examines the basic characteristics of the Hong Kong model of mixed-use development, planning mechanism and relevant policies
