Energy Management • Energy management is doing more with the same amount of energy or less energy. • Energy management saves money and makes buildings more comfortable, healthy, and safe. • Occupants can be productive

Energy Use Reduction Efficiency Conservation • Energy efficiency involves the use of technology that requires less energy to perform the same function. • Focuses on the HVAC and equipment or machinery being used • One example outside HVAC is installing LED – getting more light and less heat • Energy conservation includes any behavior that results in the use of less energy. • Focuses on the behavior of people

Why Energy Management • • • Reduces consumption Increases comfort & safety Reduces pollution Makes our economy stronger Increases our energy security Provides school personnel with real time energy and performance data to manage the building’s energy needs

Important Learned Outcomes for this Course • • • Recognize the serious nature of becoming an energy technician. Recognize basic science concepts related to energy. Demonstrate proper use of equipment and operational effective methods. Demonstrate ability to determine specific energy management findings, recommendations, and possible solutions related to energy efficiency and control of resources. Identify appropriate energy efficiency design options for new construction and retrofitting. Use processes and systems to understand manage energy and objectively address the economic aspects of energy management and gain skills to develop energy efficiency measures. Control energy use and identify energy waste and monitor the performance of measures implemented. Demonstrate understanding of energy management control systems including air conditioning and refrigeration, instrumentation, components and controls, applications, operation and maintenance. Demonstrate understanding of various energy usage equipment and energy management control techniques and facilities maintenance and operations. Demonstrate understanding of data communications including principles of signal interface, standards and codes of practice. Propose improvements and have a cursory understanding of commissioning, M&V and Energy Performance Contracting
