A building automation system or BAS is a network of controlling and monitoring devices mainly responsible for the heating, ventilation, and air conditioning (HVAC) control system in large facilities and commercial buildings. Building automation systems are most commonly implemented in large facilities such as healthcare facilities, schools, universities, hotels, residential buildings, and data centers. A BAS network allows building operators to supervise and control the HVAC systems from a centralized location known as the Building Management System or BMS. VAV system, the air handling unit (AHU) and the VAV boxes are physically separated from each other, and each one has its own controller, also distanced from one another. However, for a VAV system to operate effectively, the VAV Boxes and the AHU have to talk to each other; in other words, they need to share information to properly adjust their setpoints based on zone heating or cooling demand.
Duct & Chilled Water Pipe Insulation
System Materials Density Thickness Vapor Barrier
Duct Insulation - Glasswool <br> - Rockwool <br> - Phenolic Foam <br> - Elastomeric (NBR/EPDM) 24 – 48 kg/m³ - 25 mm (≤ 65 mm dia) <br> - 38 mm (65–150 mm dia) <br> - 50 mm (>150 mm dia) Aluminum foil or kraft paper laminate
CHW Pipe Insulation - Pre-formed rigid fiberglass <br> - Rockwool <br> - Elastomeric foam (Armaflex) — - 25 mm (General) <br> - 38 mm (65–150 mm dia) <br> - 50 mm (>150 mm dia) Required for all cold pipes (to prevent sweating & energy loss)
⚡ Quick Notes for QC/Inspection:
Always check material type, density, and thickness against specifications.
Ensure vapor barrier is intact on all cold ducts and pipes.
Insulation must be continuous and sealed properly at joints to avoid condensation.
