Energy benchmarking and savings potential


Significant increases in hospital operational costs in Malaysia are the result of the increase in energy usage and cost. This provides challenges to reduce operating costs and improve patient care. Investigation and analysis of energy performance characteristics are important to help identify areas of energy wastage and develop strategies in efficient energy usage.


Past rapid economic growth has resulted in the planning and construction of many new hospitals in Malaysia. Many existing large referral hospitals have been, or are in, the process of major physical upgrading and refurbishment to meet current revised and stringent medical standards in addition to providing new facilities and services. With a hot and humid climatic


condition most hospitals in Malaysia have become energy intensive centers. The MS1525-2007, Malaysian Code of

Practice on Energy Efficiency and Use of Renewable Energy for Non Residential Building,1


aimed at promoting energy


efficiency of buildings, has been instrumental in encouraging general awareness on energy conscious designs and operational practices. Local performance information and


benchmarking, and information on breakdown of energy consumption of hospital buildings are critical for understanding Malaysian hospitals energy profile. Through a base-case hospital

Energy assessment survey A data gathering exercise, through a survey distributed to government hospitals, has collected relevant data on building design, construction, systems, occupancy, operation & maintenance and management in relation to measured energy usage and performance. The emphasis is on annual energy consumption of hospital buildings, apportionment of major energy using

building energy-use model study, representative benchmark with viable and cost effective energy saving measures can be easily implemented through a hospital- wide sustainable energy management programme.


Malaysian hospital energy trend Figure 1 shows the monthly electrical consumption profiles of 28 selected hospitals. The annual consumption ranged from 6 million kWh/yr for a 516 bed hospital to 53 million kWh/yr for a very large 2,331 bed hospital. Although energy use intensities varied significantly between hospitals, there was only a very small variation of monthly energy usage within each hospital. This can be attributed to the fact that activities in hospitals do not vary much throughout the year and that Malaysia experiences a very small monthly variation in ambient temperature.3
