This subject covers the operation and maintenance of common utilities found in industries and the technologies used for air pollution control from point-source emissions. Topics for plant utilities include boiler systems, high-purity water, industrial chillers, and cooling towers. Topics for pollution control include types of air pollutants and their impact on health and environment, air quality monitoring, air pollution control technology and equipment.

Upon completion of the subject, learners can expect to be able to:
• Calculate corrosion/scaling and fouling potential in water utilities
• Calculate boiler efficiency
• Perform data interpretation of compressed air systems
• Explain air pollution control technology and equipment 

This subject covers the workings of common energy-intensive systems in the workplace, chiefly the HVAC (heating, ventilation and air-conditioning) system.  Among the areas covered are configurations of different chilled water distribution systems, different types of fans used in mechanical ventilation systems, types of instruments used for measurement of parameters in air-conditioning and mechanical ventilation (ACMV) systems and how the systems can be optimised for energy efficiency.

Upon completion of the subject, learners can expect to be able to:
• Explain the selection considerations for various types of ACMV systems
• Compare the different strategies used to improve energy efficiency of the ACMV system
• Analyse various air-treatment processes in the air-handling systems
• Analyse fluid flow with losses using conservation laws for pump sizing
• Examine factors affecting the selection and efficiency of motor-driven systems

This subject covers the types of motors (alternating current and direct current) and motor-operated systems such as fans, pumps and compressors, transmission drives and variable speed drives. In addition, system, fan and pump curves will be covered, together with relevant calculations on system losses, power and efficiency. 

The subject also covers various sources of renewable or clean energy such as solar, wind, hydrogen and nuclear. The current state, opportunities, challenges, and perspectives of these technologies related to achieving carbon neutrality are also discussed.

Upon completion of the subject, learners can expect to be able to:
• Apply knowledge for selection of motor types, characteristics and efficiency in the selection of motors
• Explain the power efficiency and losses in motor-operated systems
• Explain motor maintenance issues
• Explain the features of Energy Management System ISO 50001
• Explain the various sources of renewable energy and their applications

This subject covers two main areas: energy audit and energy management. For the former, the emphasis is on the general energy audit methodology, categories of audit and their procedures, the methods used to evaluate energy performance of buildings and their sub-systems, notably via energy performance benchmarks and comparison with acceptable practice as well as prevailing standards and codes. The concept of life cycle cost analysis as a tool to evaluate the economic viability of energy-efficiency improvement or energy conservation measures is also covered.  For the latter, the subject illustrates the rationale for energy management and the regulatory framework in Singapore.

Upon completion of the subject, learners can expect to be able to:
• Explain the principles and requirements for different types of energy audit
• Appraise the energy performance of typical building systems
• Analyse the impact of utility tariffs on a building’s energy bill
• Assess Energy Conservation Opportunities (ECOs)
• Analyse the financial viability and cost-effectiveness of energy projects
