| Abstract | Building Automation Systems are designed to integrate building systems, such as HV AC, lighting, fire safety, and security access control. The integration of all of these systems can reduce initial and ongoing costs, and simplify building operation. the energy consumption and cost in large office buildings can be reduced by allowing the indoor environment to deviate from the optimum comfort conditions to situations which are still acceptable by most occupants. This study investigates the potential of energy saving in HV AC system of an office building when BAS is used. The potential of the power management from usage in term of reduction of peak demand from cost saving is also evaluated, the financial viability of BAS installation does. A study building is a sample of office building using BAS to control the operation effectively in the building to reach the energy conservation goal. To control the state of AJC operation, the BAS can provide a criterion to control the active status as following details through the DDC unit. This two step control uses two-position temperature value in the data comparison. For example, if the setpoint is 26 and a differential is four, the measured temperature must rise above 28 degrees before the module controls an HV AC unit on (space is too warm). The temperature must fall below 24 before the point controls an HVAC unit off (space is too cool). This creates a control range of 24 to 28 degrees. The temperature from the RI A is not exactly representative value of the working space that we want to do a thermal comfort. For example, the RI A temperature that measured from inside the area is set to be 23 ° C by BAS program but mechanical design from this building, the VA V boxes can not work correctly there is some losses as ventilating. an average temperature from each zone representing the thermal comfort of the PCUs are not satisfy the thermal comfort according to ASHRAE Fundamental 1997 which states that the suitable comfort condition should be 25. 5 ° C. |
