Building Automation Systems Lesson 1 - BAS 101 training system basics

Introduction to Building Automation Systems (BAS)

Overview of BAS

• Building automation systems (BAS) are complex and lengthy to learn, with the aim of easing the learning process through video lessons.

• The primary motivation for implementing BAS is energy efficiency, which significantly impacts space cooling, heating, and ventilation.

Importance of Proper Utilization

• When not utilized correctly, BAS can lead to increased costs; for example, user overrides can cause prolonged heating or cooling without notice.

• Improved comfort and air quality are critical benefits; poor air circulation can result in "sick building syndrome" due to volatile organic compounds (VOCs).

Benefits of Building Automation Systems

Maintenance and Monitoring

• BAS allows for lower maintenance costs by enabling reports and notifications that help track system performance.

• Maintenance teams can diagnose issues remotely before physically inspecting equipment, saving time and resources.

Definition of BAS

• A building automation system is defined as the automatic centralized control of a building's HVAC, lighting, and other systems.

Understanding Centralized Control

Key Concepts in Control Systems

• The term "automatic centralized control" refers to intelligent microprocessor-based networks that monitor facility systems.

• Visualizing a computer helps understand how inputs (like sensors) interact with outputs (like fans or motors).

Types of Controls in BAS

Control System Categories

• There are three main types of controls: pneumatic controls, electromechanical controls, and direct digital controls (DDC).

Pneumatic Controls

• Pneumatic controls use compressed air but are less common today; they may still be found in older buildings during retrofitting.

Electromechanical Controls

• Electromechanical controls include devices like time clocks; they offer more functionality than pneumatic systems but have limitations.

Direct Digital Controls (DDC)

• DDC represents the latest technology in building automation; it replaces older systems but requires training on new software packages.

Summary of Lesson One

Recap of Key Points

• The lesson emphasized energy efficiency as a primary reason for implementing BAS while providing an overview of terminology used within the field.

• Types of control systems were discussed along with their advantages and disadvantages. Feedback from viewers is encouraged for future lessons.
