Buildings are the largest energy consuming sector in the world, and account for over one-third of total final energy consumption and an equally important source of carbon dioxide (CO2) emissions. Achieving significant energy and emissions reduction in the buildings sector is challenging; let us make it possible with intelligent building automation system!
Transition to automation from manual
Energy courses through buildings—in heating and air-conditioning systems, electrical wiring, water heating, lighting, information and communications systems, security and access systems, fire alarms, elevators, appliances, and indirectly through plumbing. Most large commercial buildings have some form of centralized, computer-based building management, used to monitor, evaluate, and control those systems. Adopting automated rather than manual building management systems can reduce energy consumption by 10 to 20 percent.
A Building Automation System (BAS) is a building’s brain. Equipped with sensors, BAS buildings are constantly scanning and rebalancing for greatest efficiency and effectiveness. Lights switch off when no one is around, for example, and windows vent to improve air quality and temperature. New buildings can be equipped with BAS from the start; older ones can be retrofitted to incorporate it and reap its benefits.
Beyond energy savings and reduced operations and maintenance costs, BAS benefits the well-being and productivity of people inside the building. Improved thermal and lighting comfort and indoor air quality directly impact occupant satisfaction. BAS is especially useful to ensure and maintain efficiency in green buildings, so that their ratings on paper match their actual performance.
Maximize energy efficiency under Building Automation System
automated control systems that can regulate a building’s heating and cooling, lighting, appliances, and more to maximize energy efficiency and/or worker productivity. This solution would replace buildings with conventional pneumatic or electric control systems.
Because of their large share of energy consumption, residential and commercial buildings now account for nearly one-third of global carbon dioxide emissions. An efficiency technology that has historically been common in large commercial buildings is a building automation system (BAS). Though many large commercial buildings in the US and EU have some form of building automation or management system, these systems are often not based on the most recent technologies.
The commercial application held the largest size of the Building Automation System market in 2016 and the trend is expected to continue during the forecast period. The increased rate of implementation of BAS in large shopping complexes, office buildings, and public transport areas such as airports and railway stations is encouraging the growth of the BAS market for commercial application. HVAC, lighting, and security and access control systems are the major products used in the market for commercial application.
Benefits of Control Systems for Green Buildings Building automation can benefit your green building in a number of ways.
- Higher Energy Efficiency
An easy one is effective occupancy control through such common practices as occupancy sensing and schedules. Surprisingly, many pieces of equipment remain unscheduled, have their schedules overridden, or are programmed incorrectly. While there are no definitive numbers, it is generally estimated that 10-30% energy savings can be achieved through scheduled control alone. Add occupancy-based scheduling and still more savings can be achieved.
- Lower Operating and Maintenance Costs
For up-front building/system design, selection of an automation system based on an open communication protocol, and BACnet® in particular, offers future proofing benefits such that subsequent updating will always lead to interoperable devices and systems. In terms of building operation, an interoperable control system can offer training-related synergies, thereby reducing or containing labor costs. With disparate systems in place, the cross-training of technicians and operators can be daunting. An interoperable system, on the other hand, means that technicians and operators can learn one front end or operator workstation while nicely managing the interoperating systems.
- Better Indoor Air Quality
Can proper indoor air quality be achieved without sacrificing costs or comfort? Today is control systems can lead to a well-tuned building where energy performance, comfort, and sustainable factors all reside harmoniously. The difference between a building that does and a building that does not is most often tied to the design and installation of the control system. This whereere qualifying your controls contractor, energy service provider, or system integrator really pays off.
- Greater Occupant Comfort and Productivity
A control system can tie building access to the activation of HVAC and lighting for a particular space (such as an office or zone). This is good for both individual comfort control (an imperative for green buildings) as well as efficient use of equipment and power. By the same token, schedules can offer similar benefits while permitting some override capability to suit individual needs. Then, there is trended or historical data which can be used to both analyze and improve building performance.[sg_popup id=6]
