Implementation of BAS (Building Automation System)

Building Automation SystemAlong with the rapid development of buildings in the industry, the energy needs also continue to increase so will the level of electricity needs to meet the needs of energy. This is possible because of the use of building utilities that are large and require a lot of energy. However, we are aware that the energy supply is limited in number, then in controlling and monitoring the equipment in the building it needs a regulatory mechanism that operator can easily do. The effort required is to save the use of it so that operating costs can be reduced, such efforts are known as energy conservation, which can then be translated in the form of efficiency and operating cost savings. Other austerity measures can also use systems that support and relate to energy savings, one of which is the automated system BAS (Building Automation System).

According to Mandariani and Zaini (2015), in building operations, three things to watch for are energy saving, occupant comfort and safety level. Therefore there are several automation systems that can be applied in the building of Heating Ventilating and Air Conditioner (HVAC), lighting, security and fire, user security access, power monitoring and transportation within the building. Integeration of these systems is known as Building Automation System (BAS).

Automatic systems in buildings or known as BAS (Building Automation System) is a centralized control system and monitoring of all mechanical and electrical equipment contained in a building. BAS consists of several Direct Digital Control (DDC) which have input and output either analog or digital. These inputs and outputs are useful as indicators for knowing the status of the device to be controlled4. BAS is also commonly referred to as the Energy Management and Control System (EMCS). BAS in a building is a system that can regulate the use of energy in accordance or limited to the required without reducing the function of equipment used and improve the ability to perform energy management of a building. For some buildings, Building Automation System is a solution to manage, control and automate the equipment and functions of the building, including Heating Ventilating and Air Conditioning (HVAC), Thermal Source, Electrical and sanitary equipment, lighting, elevators, security, fire and tenant comfort of the building.

Advantages
The advantages of BAS applications in a building, namely:
1. Operational utility can be run automatically and scheduled
2. Minimize the cost of man power
3. Efficiency of electrical energy
4. Monitoring multiple systems from one place
5. Interaction of more efficient control strategies

Weakness
Although the benefits of the BAS system are very large, there are still shortcomings in the system. The shortcomings found are the need for a high level of competence, greater risk if service is not good, high investment costs, etc. Uuntuk it needed a strategy for its management.
