Unit 52 Energy Management



Unit 52:

Energy Management


Unit code:
R/601/1419

QCF level:
5


Credit value:
15






Aim

The unit investigates energy management principles and techniques. The principal focus is to establish and develop an energy audit in the context of a plant engineering environment.

Unit abstract

This unit is concerned with energy conservation, including energy conservation awareness for both the organisation and personnel. Integral to the content is environmental management, which is now becoming ever increasingly important in energy conservation. Greater gains, both environmentally and economically, can be achieved by cutting down on waste and maximising the efficient use of energy.

Through case studies learners will investigate how environmental objectives and targets are achieved in different industrial or commercial organisations. Learners will understand how this is achieved through co-ordinating personnel, systems, strategy, resources and structures.

Learners will work on a project to ascertain the overall annual heat energy losses (or gains) of an operational building which houses plant engineering equipment and process plant. Architectural plans providing details of the building fabric and design may be helpful in calculating any heat energy gains or losses. The energy audit need not be confined to this type of project but to arrive at the outcomes the learner must demonstrate the ability to apply heat energy management concepts.

Learning outcomes

On successful completion of this unit a learner will:

1       Understand environmental management policies

2     Know about energy sources, conservation and applications

3     Understand system and energy-saving requirements

4       Be able to carry out an energy management audit.




Unit content

1      Understand environmental management policies

Environmental management: environmental management systems and policies; regulatory requirements; ISO 14000/14001

Energy technologies: power generation; transportation

Resource management: waste; hazardous waste; water; air pollution


2      Know about energy sources, conservation and applications

Sources: fossil and non-fossil (biomass) fuels; alternative sources eg geothermal Materials: thermal properties of materials; thermal conductors/insulators; K and U values Applications: heat exchangers; recuperators; regenerators; waste products

3      Understand system and energy-saving requirements

Systems: system principles; combined heat and power (CHP) and combined cycle gas turbine (CCGT) plant

System analysis: energy analysis of the process eg Sankey diagram, influence of external environment, comparable systems

Cost savings: optimum (economic) lagging; break-even costs; no-cost/low-cost energy saving measures

4      Be able to carry out an energy management audit

Energy saving: range of quantifiable techniques; costing procedures

Audit: metering and measurement of temperature, flow, pressure; data collection and analysis

Monitoring: monitoring and targeting; setting targets; performance indices; indicators

Essential requirements

Centres delivering this unit will need to have access to industrial-standard software packages used for energy management procedures and audits.

Employer engagement and vocational contexts

Centres should try to work closely with industrial organisations in order to bring realism and relevance to the unit. Visits to one or two relevant industrial or commercial organisations which use energy management techniques will be of value to enhance and support learning.
