1 Building Management Systems (BMS)Our BMS solutionHardwareWe provide a complete HVAC and lighting solution for commercial, institutional and industrial multiple product lines utilizing LonWorks and BACnet communications protocols allows us to maintain an objectiveperspective when designing and implementing solutions for our clients. In addition, this depth of representation allows us toimplement transition plans which bring clients forward out of proprietary Systems into open Systems while protecting theirexisting our Building Management software provides the operator with optimum communication between automation andmanagement SCADA system -level software is developed from considerable experience in the automation sector to bring benefits to allusers, from system integrators to end-users, by minimising investment in familiarisation and training.

5 The system is pieced together using specific interactive modules, one for each type of equipmentthat makes up a chiller plant, and together with duty coordinating modules and a capacity commander module, is able tosequence all related equipment for the proper functioning of the BMS solution - Feature HighlightsWith the HVAC and lighting controlsintegrated using our LonWorks devices,the University Campus startedoperations in the last quarter of eight chillers in two chiller plantsgenerating a total capacity 5550 tons,after fine tuning, an energy savings ofapproximately 20% was achieved infirst quarter of 2006 even with theincreasing student addition, using a variable pressureregulator for the Air Handling Unitsoperation, a saving of almost 50% onpower energy was achieved usingvariable static pressure regulator insteadon standart constant pressure diagram shows comparison of AHU duct pressurewhen using constant static pressure control method(purple) and UVP-LD (blue).

6 The initial spike shows how the UVP-LD allowed forhigher static pressure to improve cooling/heatingresponse, allowing the space temperature to reachdesired set-points sooner than a constant static pressuresystem is able to achieve. After that, the duct pressuremaintained was considerably lower than when controlledwith constant pressure method - resulting in huge energysavings without compromising on space temperatureReal installation testing has revealed that saving ofalmost 50% on power energy was achieved using variablestatic pressure regulator instead on standart constantpressure AdvantagesAHU fan runs at lower average speeds resulting in moreenergy savingsIndividual VAV boxes receive 'just enough' cooling airflow resulting in more effective cooling in individual roomsCooling demand is met more quickly and efficientlyRequires no modification of existing hardware
