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.

The Impact of Climate Change
External and Internal Design Conditions for Air Conditioning Loads Estimation
Overview
Climate change affects the design conditions for air conditioning systems. Rising temperatures and fluctuating weather patterns require careful consideration of both external and internal factors...
Challenges
- Increased external temperatures resulting in higher cooling loads.
- Unpredictable weather patterns complicating design standards.
- Heat islands in urban environments creating localized heat challenges.
Solutions
- Using adaptive design criteria based on climate forecasts.
- Implementing energy-efficient air conditioning technologies.
- Promoting sustainable building materials to reduce heat gains.
