Following up on my earlier post entitled “Green AV through Control System Programming”, I promised to share programming-centric Green AV solutions. A great example of how control system programming and Green AV intersect is through energy management solutions.
Energy management is a hot topic these days with the recent adoption of the ANSI/InfoComm Audiovisual Systems Energy Management standard. Energy management involves a combination of design, programming, settings, and measurement. The process resembles the age-old scientific method of developing a hypothesis, defining an experiment, evaluating the results, and refining the hypothesis until it proven.
Energy management starts with establishing a baseline of energy usage, making a commitment to energy savings, and establishing a goal. From there, the process involves the following steps.
- Make system adjustments
- Measure results
- Review the outcome as compared to the goal
- Repeat the process by refining system adjustments
Control system programming is a key component in this process not only providing the control of the devices that are to be powered off and on and measuring the results, but most importantly providing the ability for user adjustment.
Automatic system shutdown is a great example energy management that can be designed or approached in various ways and refined with user adjustment. Options for accomplishing automatic system shutdown can include one or more of the following criteria:
- Time of day
- Daily or weekly schedule
- Room vacancy
User adjustment of individual parameters provides the ability to identify the impact of settings in achieving established energy management goals. Variable shutdown times, adjustable inactivity timeout before shutdown, sensitivity of occupancy sensors, or a combination criteria such different settings during business hours vs. outside of business hours are such examples.
