Course Outline

After participating in this course, you will be able to:
Recognize the main features of a direct digital control system that impact operational
   efficiency of large commercial, institutional and industrial buildings
Use your knowledge of direct digital control systems to identify energy saving opportunities
Conserve energy by implementing the strategies learnt at the course to optimize the direct digital controls
Improve the efficiency of the operation by eliminating waste and by enhancing performance
Identify the upgrade requirement of your system that help in improving efficiency of energy operations


Direct Digital Control systems are applied almost universally these days to control Heating, Ventilation, Air Conditioning and Lighting systems, which are primary users of energy in buildings. Controls being key element for proper operation of these systems have significant impact on buildings’ energy consumption. Direct Digital Controls with their versatile functionality can play crucial role in improving energy efficiency of building systems. They influence energy savings directly by optimally controlling temperature, run time and other parameters, and indirectly, through their ability for monitoring and reporting of energy consumption. However, often DDC systems are not utilized to their full potential for energy savings.

By attending this course you will enhance your understanding of DDC systems and how their various characteristics have impact on energy usage. The course aims to empower the facility management personnel to optimally operate and manage DDC systems and equip them with techniques for implementing saving energy strategies.


To provide participants with a thorough understanding of DDC systems and their operational strategies to improve energy efficiency and save utility costs in commercial, institutional and industrial buildings.

Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
