  1. Building Automation

  2. Intro • Building automation describes the advanced functionality provided by the control system of a building. • A building automation system (BAS) is an example of a distributed control system. • The control system is a computerized, intelligent network of electronic devices designed to monitor and control the mechanical, electronics, and lighting systems in a building.

  3. Topology • Primary & Secondary Bus: • Low level or High Level Controllers • Input / Output Devices • Human Interface Device • Wireless Network (can be ZigBee) • Input & Output • Analog • Variable Measurement • Temperature, Humidity, and Pressure Sensor • Digital • Switch On or Off • Photocell

  4. Structure of BAS

  5. Components of BAS • Controllers • Programmable Logic Controllers • System / Networks Controllers • Terminal Unit Controllers • Occupancy • Temperature Sensor • Lighting • Photocell

  6. Components of BAS (Contd..) • Air Handlers • Indoor Air Quality • Demand Control Ventilation • Central Plant • Chilled Water System • Condenser Water System • Hot Water System • Alarms and Security • Fire and Smoke Alarm System

  7. Components of BAS

  8. Live Preview of BAS

  9. Why BAS? • Keeps the building climate within a specified range • Provides lighting based on an occupancy schedule • Monitors system performance and device failures • Provides malfunction alarms (via email and/or text notifications) to building engineering/maintenance staff • Reduces building energy and maintenance costs when compared to a non-controlled building. • A building controlled by a BAS is often referred to as an intelligent building or a smart home.
