What is Building Automation?
HVAC and Lighting Controls – Stand
alone computerized controllers are installed to take over the control of building HVAC (heating, ventilation, and air conditioning)
systems and lighting. The building is not only scheduled more closely but it is also operated more intelligently and efficiently.
Outside Air Optimization - Proper control of outside air provides necessary inside
air changes for occupant comfort and health, minimizes energy costs by space pre-conditioning, allows for enthalpy based free
cooling, and reduces the use of outside air when it is not needed.
Coordinating Equipment - Orchestrating the operation of building systems, so that
equipment works together, saves energy and improves comfort. Individual control systems that are not centrally monitored and
coordinated can fight each other or malfunction, causing comfort problems and wasting considerable energy. We can interface
to existing or planned systems so that the building will run smoothly and at peak efficiency without expensive duplication
of controls or unnecessary complexity.
Graphical Operation - Simplifying
facility operation and integrating data from various systems in a "seamless" manner is best accomplished with a
graphical user interface. This eliminates the need to memorize commands or point numbers, and allows the operator to take
a walking tour of the facility from the console. Existing systems can be easily upgraded to add this powerful operational
tool. Point and click graphics empowers management by letting everyone see what’s going on and taking the mystery out
of proper operations.
DDC Controls - We upgrade older existing equipment to DDC controls to match
new equipment functionality. These controllers come standard on most new mechanical equipment and are more reliable, require
less maintenance, provide more sophisticated control, and are less expensive to purchase and operate.
Tighter Scheduling - Conventional controls, such as timeclocks, are inaccurate and
are typically setup to run equipment longer than the actual need. By automating this function with computerized controls,
the computer can predict the optimum time to start/stop equipment and eliminate waste caused by excessive runtime.
Smarter Control - HVAC equipment is typically sized to handle the building load under
worst case conditions. Most conventional controls are set up to meet these design criteria at all times. With the automation
system, control setpoints and strategies can be adjusted to meet only the actual load, eliminating unnecessary waste.
The Immediate Benefits Are?
Lowers utility costs - C-mation typically
saves 20% of the operating costs of the equipment that we control. For most buildings this results in savings that range from
$0.20 to $0.40/square foot.
Maintains measured comfort – Computerized
controls help to maintain even temperatures and lighting levels within the facility to provide measured comfort. Maintaining
consistent temperature and lighting levels cuts down on wasted energy.
Enhances property value – The value
of most commercial buildings is related to the net operating income. Lowering utility costs increases the net operating income
on a dollar for dollar basis. Every $0.10/square foot saved in energy could increase the market value of the property by $0.80/square
foot. A 150,000 square foot building could increase in value by $240,000 by reducing energy costs $0.20/square foot
Reduces occupant complaints – A more comfortable
building means fewer occupant complaints. This means less time resolving complaints, happier occupants, and a more productive
business environment.
Simplifies building operation – Computerized
controls and real time graphical displays let you see exactly what’s happening with the equipment in the building without
having to go up on the roof or crawl up into the ceilings. This saves on costly problem determination visits, and simplifies
operations.
Reduces maintenance costs - Running the equipment
less and controlling it better reduces wear-and-tear and keeps maintenance costs down.
Avoids business interruptions – Unexpected
equipment breakdowns can cause very costly business interruptions. The cost of employees and or processes in a building can
easily be 50 to 100 times the facility operating cost on a square foot basis. The impact when customers are involved can be
equally costly. Breakdowns and emergency repairs are be very expensive. Computerized controls monitor equipment status and
help you head-off unexpected problems.
Is a great investment – Most systems pay
for themselves in two years or less from energy cost savings alone.
It Makes Quantum Improvements Possible – There is a connection between operating cost,
environmental quality, and profitability. Computer technology is the key to managing facilities and costs effectively. Without
better tools, the existing personnel can’t keep up with increasing demands. Either quality suffers or costs increase
in other areas (like contracted services, utility charges, or personnel).
