By the end of this course, learners will understand the key principles used to design and size Air Handling Units (AHUs) for typical building applications. They will learn to interpret project requirements, identify major AHU components, determine airflow and capacity requirements, and evaluate filters, coils, dampers, fans, sensors, and actuators used in HVAC systems. Through practical examples, guided calculations, case studies, and interactive activities, learners will explore how design requirements influence AHU configuration, equipment selection, energy performance, and system operation. The course also introduces how AHU design information is translated into BMS monitoring points, control requirements, and engineering documentation. This course is suitable for learners entering HVAC, BMS, building automation, and facility engineering roles who want to develop a practical understanding of AHU sizing before progressing to control logic, interface design, and commissioning.

Syllabus

Introduction to Sizing in BMS Systems
- This module introduces the principles and practices of system sizing within Building Management Systems (BMS). Learners will explore why proper sizing is critical for energy efficiency, performance, occupant comfort, and safety. The module also develops the skills needed to analyze technical specification documents and extract sizing requirements accurately. Finally, learners will become familiar with the tools and software commonly used to support sizing decisions and optimize BMS design outcomes.
System Sizing for Air Handling Unit (AHU)
- This module guides learners through the process of sizing and selecting Air Handling Unit (AHU) components for HVAC systems. Learners will develop functional analyses based on client needs, create operational scenarios, evaluate technical constraints, and perform equipment sizing calculations. The module also covers equipment selection, capacity determination, BMS integration, and practical application through a real-world AHU design case study.
Challenges and Solutions in HVAC System Sizing
- This module explores the challenges and decision-making processes involved in HVAC system sizing and Building Management System (BMS) design. Learners will examine the technical and economic constraints that influence equipment selection, evaluate strategies for creating scalable and flexible systems, and develop communication architectures that support seamless system integration. Through practical examples and case studies, learners will learn how to balance performance, cost, reliability, and future growth requirements to create efficient, adaptable, and future-ready HVAC and BMS solutions.
