A building control system is a centralized system that monitors and controls various building systems and equipment to ensure efficient operation, occupant comfort, and safety. These systems are commonly referred to as; Energy Management Systems (EMS), which is responsible for managing environmental functions within a building; Building Automation Systems (BAS), which focuses on controlling technical automation processes; and Building Management Systems (BMS), which encompasses a broader range of functions, including providing status reports on environmental conditions, monitoring elevator operations, and tracking the location of individuals for security purposes.
Detailed Explanation
A building control system is like the brain of a building, coordinating various functions to keep the environment comfortable and secure. This includes managing energy use (EMS), automating various operations (BAS), and overseeing larger systems (BMS). These systems work together to ensure everything from heating and cooling to security operates smoothly.
Examples & Analogies
Imagine if your house had a smart brain. This brain knows how hot or cold it is inside, whether anyone is home, and even when to turn on the lights. Just like how your smartphone can control many things in your home, building control systems do the same for bigger buildings.

The major functions are, as follows;
- Data Analysis and Reporting: Building control systems provide data analysis and reporting capabilities, enabling facility managers to assess building performance, identify trends, and make informed decisions for improving energy efficiency and operational effectiveness.
- Monitoring and Control: Monitoring systems collect data on various parameters such as temperature, humidity, occupancy, and energy consumption to monitor the building's performance and ensure it operates within predefined limits. Based on the collected data, the system can automatically adjust and control the building systems to maintain optimal conditions. For example, it can regulate HVAC systems to provide comfortable temperatures or adjust lighting levels based on occupancy.
- Management and Decision-aid: Building control systems help optimize energy usage by tracking energy consumption, identifying inefficiencies, and implementing strategies for energy conservation, such as scheduling equipment operation and implementing demand response programs. The system also generates alerts and notifications in case of equipment malfunctions, abnormal conditions, or security breaches, allowing facility managers to take prompt action.
Detailed Explanation
Building control systems come with several essential functions. First, they analyze data, helping managers understand trends and improve efficiency. Second, they monitor conditions, ensuring the building's systems like heating and cooling are functioning properly. If it's too hot or cold, the system can adjust itself. Lastly, they aid in energy management by tracking how much energy is used and alerting managers if something goes wrong, allowing for quick fixes.
Examples & Analogies
Think of building control systems like a smart thermostat and an energy monitor combined.

A building and its indoor spaces are constantly influenced by both internal and external factors that can disrupt the indoor climate, such as heat, air emissions, and changes in humidity levels. Climate control in buildings refers to the adjustment of indoor climate conditions according to the preferences of the occupants, while ensuring that external weather conditions, such as extreme heat or harsh environmental factors, do not impact the indoor environment. Indoor Environment Quality (IEQ) refers to 'the quality of a building’s environment in relation to the health and wellbeing of those who occupy space within it'. The four primary parameters - thermal, visual, and acoustic comfort, indoor air quality (IAQ), have direct impact on various aspects of human well-being, such as, occupant comfort, productivity, mental health, satisfaction, as well as study and work performance.
Detailed Explanation
Climate control systems manage the building's internal climate, adjusting settings according to what occupants prefer, while also shielding them from outside weather issues. Indoor Environment Quality (IEQ) measures aspects of the indoor climate - such as temperature, sound, and air quality - that significantly affect how people feel and work in the space. Good IEQ leads to happy, productive people.
Examples & Analogies
Picture yourself in a room where the heating keeps kicking on and off, making it uncomfortable. A good climate control system is like a thoughtful host who constantly checks if everyone is comfortable, adjusting the heating, cooling, and lighting as needed, just to make sure you're happy and focused.

Active and Passive design strategies are employed to improve IEQ and liveability of a building. ‘Active’ implies the use of mechanical and electrical systems, such as air-conditioning, heat pumps, radiant heating, heat recovery ventilators, and electric lighting which uses purchased energy, while ‘Passive’ refers to harnessing available ambient energy through techniques such as maximizing natural light (daylighting), utilizing natural airflow for ventilation, and garnering solar energy.
Detailed Explanation
There are two main types of design strategies for maintaining a good indoor climate: active and passive. Active strategies involve the use of electronic systems like air conditioning and heating that require energy. In contrast, passive strategies leverage natural elements like sunlight and wind for cooling and lighting, reducing the building's energy consumption.
Examples & Analogies
Imagine you have two different methods to keep cool on a hot day. One method is using an air conditioner, which uses electricity (active). The other is opening windows for a cool breeze while using shades to keep the sun out (passive). A building that uses both methods intelligently can keep the indoor climate comfortable while saving on energy costs.
