In order to continue to meet the demand for programmers in the industry and support the growing number of control system related projects, it seems clear that there needs to be a standardized development program. This training program or collection of courses would be geared toward teaching not only the logical thinking that goes into control system programming, but also all of the related skills like troubleshooting, networking, signal flow, project management, etc.

Having an advanced certification, such as a CTS-P from InfoComm, geared toward programming would help to provide an non-biased or agnostic way of developing skills and identifying qualifications. This concept would certainly not replace the need for manufacturer’s training, it would only augment the knowledge base leading to more well-rounded programmers.

In a previous discussion, I mentioned the fact that it’s easy being “Green-er “ in AV and talked about the collective effort and responsibility of building Green AV systems.  From manufacturers to designers to technology managers to programmers, each constituent plays a role and has a particular responsibility.

So where do we begin?  Can any system become Green?  Or are there pre-qualifications or requirements for Green AV systems?

Green does not have to be an idealistic term.  Sure, we would like to have the most energy efficient system, the most environmentally consciously manufactured equipment, and save the most money in the process; however, it’s better to be Green-er than not worry about being Green at all.

Any integrated AV system can become “Green-er” by applying the appropriate control system programming solutions.  Features such as automatic power down routines to power off the system when not in use, occupancy/vacancy sensors to detect presence in the room, power on devices on an as needed basis instead of powering on all equipment when the system is activated, restricting usage to authorized parties so that equipment is not used unnecessarily, etc.  It is important to know that software is the driving factor in this area and software solutions can be applied in most every system.

The next question is how do you quantify your Green AV system?  There are means to measure a baseline of power usage with all equipment full on and then measure the difference after applying Green AV solutions.  As long as there are savings of energy, the system has now become Green-er.  It is important to realize that there is not only way to apply Green AV solutions.  In fact, there needs to be a delicate balance between being Green and maintaining a high level of system performance and responsiveness for the user.

As a result, the most effective Green AV control system programming solutions involve providing user configurable controls to allow the Green AV features to be tailored to the meet the users’ needs and strike the proper balance.

For example, when applying an automatic system shutdown, the user may have the opportunity to select a shutdown time in small intervals, select a different schedule for week days and weekends, and make adjustments to timeouts of occupancy/vacancy sensors indicating how long to wait to power off the system when not in use.  The difficulty comes in when as system is prematurely powered on and then needs to be powered back on again right away causing the potential of a delayed response.  In this respect the owner or operator of the system can determine how important it is for them to conserve vs. maximize usability and responsiveness.

In upcoming articles, I will explore various control system programming-centric Green AV solutions.  Each one will offer benefits and may be approached in various ways offering user settings to provide customization and adjustments so that we proper mix of Green AV and system responsiveness can be achieved.

Manufacturers can be called upon to produce “greener” products through environmentally conscious processes as well as by  including features for energy management and reporting and improved control functions like discrete control for on and off, standby features, and economy modes.

Consultants and Integrators can support Green AV by specifying “green” products and by designing systems in which components can managed as to their energy usage by receiving feedback to enable control and monitoring of power states.

Owners and End Users should be educated as to the benefits of Green AV, so that appropriate purchasing decisions are made.  Facts and figures through marketing as well as data and real-time measurements through system design and system monitoring can help in making the case and creating the demand.

A significant area that needs to be considered in support of Green AV is the importance of Programmers.  Control system features and functionality can make any system “greener”.  Additionally, the combination of green programming features, system design, and device specification can provide the ability for a system to be fine-tuned as to its energy usage by balancing energy management with system functionality and effective operation.

Technology Managers should not only request and support Green AV products, system designs, and functionality, but also effectively utilize the programming features and functionality to maximize their effectiveness.  Additionally, by having the ability to monitor, make adjustments, and compile data, the value and benefit of green features may be measured and justified.

In summary, Green AV provides environmental benefits, energy savings, cost savings, and efficiency by limiting down time through leveraging controls to extend device life, optimizing consumables like lamps, and providing increased system monitoring.  Green AV requires a collective effort; however, it is easy to get started to make any system “greener” through effective control system programming practices.

Choose to work with a programming resource or programmer who is industry certified, reputable, and adheres to industry best practices.

Qualifications, a proven track record, fair pricing, and reliability are basis for working with a service provider of any type (industry or non-industry related).  So why risk the outcome of your project by utilizing an unqualified or unproven resource because they provide a low cost solution or fit into an unrealistic budget?

Aside from the quality of the product, the following are some additional criteria that define a qualified programming resource

• Adhering to a consistent, efficient, and thorough project process
• Taking the users’ needs into consideration in proposing a solution
• Providing a functionality submittal in advance of programming, defining the solution
• Listening and responding to customer feedback
• Customization and branding of their product for specific client
• Attentiveness and responsiveness
• Support and commitment
• Timeliness and flexibility

InfoComm’s Independent Programmers Council is establishing best business practices for independent programming companies as well as standards of excellence for all programmers with the intent of enhancing customers’ experiences with programming.   These qualifications will serve to raise the bar for programming and limit the risk and temptation to work with lower cost, sub-par providers by identifying reliable resources that are committed to providing quality, effective products and services that adhere to industry guidelines.

Established processes, reliable support, industry certifications, legal compliance, and company stability are standards that are foundations of the best business practices.  Knowing that your system will be effectively programmed, that the programmer will be qualified and responsive, and the source code will be well-written, documented, and available for future needs are just a few of the standards of excellence.

Think about it this way, when you undergo a medical procedure or operation, are you satisfied with simply selecting a hospital to go to or are you more concerned with the qualifications and capabilities of the doctor who is performing the procedure? 

Don’t risk the outcome of your project; remember to Know Your Programmer.
