    (Journal of Business and Social Development, 2015) A.A. AZLINA; ENGKU SITI ZAHARAH ENGKU ABDULLAH; MAHIRAH KAMALUDIN; ALIAS RADAM
    This article discusses the trends in residential sector’s growth and energy consumption pattern in Malaysia. Residential sector has been regarded by researchers as an important target group for energy conservation. In Malaysia, energy use of the residential sector accounts for about 15% of that consumed by all sectors. Although it is ranked at the fourth place after other major sectors such as industrial, transport and non-energy, energy consumption in the household sector has become important because the increase of energy consumption in household sector is portrayed as a major threat to the sustainability where it will increase the CO2, and will generate major global problems like greenhouse gas effect, ozone layer depletion and acid rain.

    IMPROVEMENTS IN DOMESTIC WATER SERVICES IN KELANTAN
    (Journal of Sustainability Science and Management, 2013) MAHIRAH KAMALUDIN; KHALID ABDUL RAHIM; ALIAS RADAM; MOHD RUSLI YACOB
    This study evaluated the willingness to pay by the people in Kelantan for improved domestic water services. Unsatisfactory services by the Kelantan water company are a long-standing issue in the state. Excessive water consumption, frequent interruptions, rapid social and economic growths are putting higher demands for quality of services and the water company is unable to cope with the growing number of populations. This study employed Choice Experiment (CE) method to examine other possible preferences in domestic water services. This method highlighted four attributes such as water quality (QUAL), water interruption (INT), non revenue water (NRW) and water prices (WP) in its services. Respondents were required to trade off their income for positive changes in the services. Basic and interactions in Conditional Logit (CL) models were estimated to account for heterogeneity in the selected choices of the consumers from options provided in water service attributes. A survey has been carried out with 552 respondents based in every district (stratum) in the state. It is interesting to note that of the four attributes considered in this study, reducing the frequency of water interruption becomes a priority in the services for the population.
