Building Automation

Building Automation and Controls (BAC) enhance comfort and productivity while using less energy, thus reducing costs and bills.

All too often, energy improvement in buildings is only focused on the building fabric (such as insulation) and the installed equipment (like LEDs or high-efficiency boilers), but overlooks the opportunities in more efficient and dynamic operability. This is where advanced controls and automation enter the picture.

Acting as stand-alone and related to individual technical building systems, such controls can save vast amounts of energy in the average building. These savings further rise when control systems interact with each other, such as via a building energy management system (BEMS). Moreover, such a system would early detect faults in operation and diagnose defects in technical building systems.

Building technologies also interact with the energy system – outside the building. A smart building can automatically adapt (within preset individual preferences) according to changing energy needs and price fluctuations. The (automated) building stock facilitates the use of renewable energy sources and increases the overall grid stability by providing the grid with massive load shifting and storage capabilities.

Building Automation
Examples of energy reduction measures that can be realized with improved building automation and controls: Smart HVAC (1) controls use sensors to limit energy consumption in unoccupied zones; Automatic hydronic balancing (2) continuously adjusts the flow and pressure in the piping system and radiators to optimize generation, distribution and emission of heat throughout the building; Sensors and drives (3) enable variable demand control of ventilation optimizing the level of indoor air quality at minimal energy cost; In sanitary hot water, advanced controls (4) can reduce the temperature without causing health risks because of legionella; Advanced lighting controls (5) avoid overuse by dimming functions that adapt to daylight and occupancy; Solar shading (6) manages the amount of solar heat and daylight that enters the building
