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.

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 optimized for energy efficiency.

This subject covers types of motors (alternating current and direct current), types of fans, pumps and compressors, types of transmission drives, fan and pumping systems power and efficiency, calculation of losses in compression systems, fan/pump curves and energy efficiency improvements.

A significant portion of the module will be devoted to giving insight to learners of the various sources of renewable or clean energy, including the challenges and opportunities faced by each form of energy.  Renewable energy such as solar, wind, hydro, etc. are discussed within the context of Singapore. Also included in this module are current alternative “cleaner/low carbon” sources of energy (compared to energy derived from petroleum) such as LNG, Lithium battery, fuel cells, etc., together with carbon-neutralising technologies such as carbon capture and sequestration.

This subject covers energy management systems based on ISO 50001 which provides the requirements for establishing, managing and improving organisations’ energy consumption and efficiency. Related topics covered include energy audit including ISO 50002, parameters pertaining to energy performance, financial evaluation of energy efficiency improvement projects using simple payback method, return on investment, cashflow analysis, time value of money, discounting rate and net present value.
