contractors for meeting key energy performance indicators (KPI) with regards to the performance of the cooling system DEVELOPMENT POLICY MAKING Decision Making Process Apar t from some developments such as Putrajaya, KL Sentral and KLCC, township development and engineering decisions are made independently by different authorities, by different decision makers, on different timelines and with different design practices. Decisions on DC are made without any proper guidelines and more often are dictated by marketing trends and commercial incentives rather than sustainability objectives. “Green” technologies are marketed with the objective to increase profitability; not sustainable living. Policy Efforts by the Kementrian Tenaga, Teknologi Hijau dan Air (KETTHA) through Low Carbon Cities Framework (LCCF) have yet to bear fruit as adoption by local authorities still leave much to be desired. Lack of clear direction on energy efficiency policies in Malaysia hampers the growth of DC industry and exposes the players and consumers to too many uncertainties. Development of the DC industry should be put on the same pedestal as the development of other utilities such as, power distribution and generation plants, telecommunication and water supply scheme. DC requires integrated planning to ensure viability and sustainability of the business. DC investment is capital intensive with a long gestation period. Therefore, without proper planning during the project inception stage, a DC provider may face financial difficulties in the future and may not be able to provide quality service to the customers. Examples of successful integrated DC planning in township development are KLCC, Putrajaya, Cyberjaya and KL Sentral. Similarly, campus DC planning such as USIM and UITM Puncak Alam benefit from savings in capital expenditure and high utilization of assets by using DC rather than having multiple in-building chiller plants. Figure 2 Shinjuku Tokyo DCS plant Sustainability Planning Town planners often locate the DC plant at the far-end corner for fear of unsightly cooling towers. This practice further increases the capital cost of serving the load due to distance. Practices in other countries such as Japan Shinjuku DC Plant (see Figure 2); have located the plant at the centre of the township which helps ensure a sustainable business. Integrated planning between various utilities also allows for resource efficiency. For example, the DC plant may use treated water from a waste treatment plant or drainage water from the retention pond for the cooling tower use. This encourages efficiency and conservation of natural resources. However, without having proper perspectives of planning these utilities, the lofty ideals may come to nought. IS A REGULATORY FRAMEWORK THE ANSWER? At this juncture, the DC business is unregulated although it involves public safety, financial risks and creature comfort. The current business model is based on a “willing buyer-willing seller” basis. Due to this, there are complaints of over-charging by DC operators and poor quality of service or the lack of it. On the other hand, the DC operator relies entirely on the commercial contract with the 65
