Total Laboratory Energy Management (TLEM)

Energy Efficiency and TLEM

An approach to laboratory energy monitoring and control is suggested which is called "Total Laboratory Energy Management" (TLEM). TLEM incorporates advanced features and enhancements to control systems with the long-range objective of managing energy use for the life of the laboratory facility. A TLEM approach includes maximizing the power of computers to evaluate all interacting variables that affect the laboratory's energy consumption. A variety of enhancements and evaluation tools have become available to expand and extend the EMCS's power to improve the facility's function and energy efficiency. An energy engineer will need to consider the ability of the PMI software program to take advantage of the latest tools and techniques. Some of the analyses and enhancements evaluation tools make possible with available "desk top" computers include:

·PID loop tuners,

·DDC program simulation,

·Feed-forward peak load management,

·External maintenance program interfacing,

·Touch screen interface,

·Real-time energy evaluations,

·Enthalpy stabilization,

·Multivariable control strategies,

·Dynamic interfacing with energy calculation programs,

·Fuzzy logic, and

·Artificial neural networks.
