Benefits of Building Automation Systems - Modern buildings use DDC controls for building automation systems. Building automation systems offer energy savings because they are energy management systems. These systems allow management to automatically control many processes involved with HVAC systems, lighting, and emergency systems. The systems are generally hooked up to the internet so monitoring and control can be done worldwide. (more…)
Air Handler Equipment DDC Controllers – These controllers will control an air handler once the wiring is completed. The panel is freshly mounted and waiting for the technician to run the piping and pull the wire from the control points. Other points, such as outside air, temperature sensors in piping or ductwork, flow meters, actuators, or other control points can be terminated to these controllers and the data collected from those input points can be networked over the entire building automation system through the communication trunks.

Economizer Systems and HVAC Control - Direct Digital Controls Systems in HVAC control have taken leaps and bounds in the last few years. Especially so in being user-friendly, ease of designing systems, troubleshooting system problems, and increasing efficiency over the older energy management systems. When discussing the increasing efficiency of systems the idea of economizing always comes up. (more…)
DDC Automated Logic M-Stack - This Automated Logic M-Stack provides a control for multiple pieces of HVAC equipment and integrates network communication all in one single stack. This direct digital control system is integrated with pneumatic controls. DDC allows automated HVAC control processes to take place and adds higher efficiency to an HVAC system. (more…)
HVAC Tip - Did you know the human body produces approximately 250 BTU/h when sleeping? Here is a basic list of the approximate BTU/h produced by the human body for various activities:
Watching Television - 400 BTU/h (any sedentary activity)
Cleaning the house - 700 BTU/h (moderate activity)
Mowing the Grass w/push mower - 1800 BTU/h (heavy activity)
Running a marathon - 2400 BTU/h (extreme activity)
The number of people occupying a dwelling or space is a consideration in the load calculation for sizing air conditioning systems simply because humans do give off heat. BTW, the Matrix over blew the numbers. In the movie Morpheus states humans give off over 25,000 BTU's. Only the author of this website is that hot..............))))))
