The Impact of Building Automation Systems
Building Automation Systems (BAS) have revolutionized the way we manage and control large buildings. They have brought about a significant shift in the way we perceive energy efficiency, indoor air quality, and overall building management. Let's delve into the profound impact these systems have on our buildings and, by extension, our lives.
The first and foremost impact of BAS is on utility costs. When used correctly, building automation systems generally pay for themselves fairly quickly through lower utility bills alone. Simply monitoring building occupancy and allowing the BAS to adjust HVAC use accordingly results in savings of 10% to 30%. Reductions in peak load and other energy use benefits reduce utility costs even further.
The second impact is on the indoor environment. Improved ventilation and air quality boost greater worker productivity and reduce sick time. Studies conducted by Harvard and SUNY Medical Centers found that doubling ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) minimum ventilation rates through energy-efficient HVAC systems boosts cognitive function. Workers in well-ventilated, green-certified buildings scored 26.4% higher on cognitive function tests and had 30% fewer sick building symptoms than those in non-certified buildings.
The third impact is on maintenance costs. By reducing demand and start/stop stages, building automation systems reduce wear-and-tear on a building's energy infrastructure, reducing maintenance costs and extending equipment life. Computerized controls monitor equipment status and help you head-off unexpected problems.
Lastly, BAS simplifies building operation. Computerized controls and real-time displays provide instant and ongoing feedback on everything that’s happening with the equipment in the building – without having to physically examine the equipment. This saves on costly problem determination visits, avoids business interruptions, and simplifies operations.
In conclusion, the impact of Building Automation Systems is profound and far-reaching. They not only make our buildings smarter but also contribute to a more sustainable and energy-efficient future.
- Building Automation Systems significantly reduce utility costs, leading to substantial savings.
- They improve the indoor environment, leading to increased worker productivity and reduced sick time.
- BAS reduces maintenance costs and extends the life of building equipment.
- They simplify building operation, providing real-time feedback and control over building systems.
The Future of Building Automation Systems
The future of Building Automation Systems (BAS) is being shaped by the latest technology trends and the growing demand for sustainability. Modern buildings are no longer just brick-and-mortar structures. They are designed to improve comfort for occupants while optimizing energy spend. As the concept of smart buildings gains acceptance across the globe, there is an increasing need for BAS designed to meet the complex needs of intelligent buildings.
In the past, a BAS was primarily deployed to automate HVAC functions. However, a smart building is more than just automated HVAC functions. It includes access control, lighting, energy management, temperature regulation, and a vast range of other functions. As a result, a BAS is being increasingly used as a single-pane-of-glass user interface for command and control of multiple building operations to improve efficiency and detect vulnerabilities in an interconnected system of equipment.
Key Trends Influencing the Future of BAS
- Introduction of Consumer IoT Technologies: Consumer IoT devices such as smart alarms, security systems, thermostats, and home appliances have gained steady popularity in recent years. Introducing these technologies, especially in HVAC systems, in commercial buildings will allow both building owners and occupants to have more control over indoor environments and receive detailed insights on temperature, humidity, and indoor air quality.
- Inclusion of IP-Based Devices: A future-focused BAS can offer enhanced scalability with the inclusion of new equipment into the building network without laying more fiber or Cat6 cables or reprogramming individual devices to create room in IP address ranges.
- Software As A Service (SaaS): The future of BAS is cloud-hosted, software-as-a-service (SaaS) solutions. This shift from dedicated BAS proprietary platforms to open platforms to SaaS-based solutions reduces operational costs as building owners do not need to maintain costly software or hire application-specific programmers.
- Increased Usage of Indoor Air Quality Sensors: With healthy buildings becoming a priority, indoor air quality sensors will be heavily relied upon to determine the cleanliness and safety of indoor spaces.
- New Standards for HVAC Configurations: Future designs for HVAC systems will be heavily influenced by new configuration standards, such as the Wired Certification Guidelines and the WELL Building Standard.
- Implementation of Climate Impact Goals: As governments and private businesses increasingly recognize the adverse impact of GHG emissions by commercial buildings, state governments are implementing climate impact goals with a focus on low-carbon architecture.
While multiple trends will transform building automation, they have a common thread: data analytics. Intelligent data analytics in a BAS offers a high-level overview of entire operations across the building with actionable insights on energy consumption, system performance, and proactive maintenance and repairs.
