Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning , lighting and other systems through a building management system or building automation system BAS.

The objectives of building automation are improved occupant comfort, efficient operation of building systems, reduction in energy consumption and operating costs, and improved life cycle of utilities. Building automation is an example of a distributed control system — the computer networking of electronic devices designed to monitor and control the mechanical, security, fire and flood safety, lighting especially emergency lighting , HVAC and humidity control and ventilation systems in a building.

BAS core functionality keeps building climate within a specified range, provides light to rooms based on an occupancy schedule in the absence of overt switches to the contrary , monitors performance and device failures in all systems, and provides malfunction alarms to building maintenance staff. A BAS should reduce building energy and maintenance costs compared to a non-controlled building.

Most commercial, institutional, and industrial buildings built after include a BAS. Many older buildings have been retrofitted with a new BAS, typically financed through energy and insurance savings, and other savings associated with pre-emptive maintenance and fault detection. A building controlled by a BAS is often referred to as an intelligent building, [3] "smart building", or if a residence a " smart home ". Commercial and industrial buildings have historically relied on robust proven protocols like BACnet while proprietary protocols like X were used in homes.

Accordingly, commercial, industrial, military and other institutional users now use systems that differ from home systems mostly in scale. See home automation for more on entry level systems, nVoy, Almost all multi-story green buildings are design to accommodate a BAS for the energy, air and water conservation characteristics.

Electrical device demand response is a typical function of a BAS, as is the more sophisticated ventilation and humidity monitoring required of "tight" insulated buildings. Most green buildings also use as many low-power DC devices as possible.

Even a passivhaus design intended to consume no net energy whatsoever will typically require a BAS to manage heat capture , shading and venting, and scheduling device use. The term building automation system , loosely used, refers to any electrical control system that is used to control a buildings heating, ventilation and air conditioning HVAC system. Modern BAS can also control indoor and outdoor lighting as well as security, fire alarms, and basically everything else that is electrical in the building.

Modern systems rely on standards-based multi-protocol heterogeneous networking such as that specified in the IEEE These accommodate typically only IP-based networking but can make use of any existing wiring, and also integrate powerline networking over AC circuits, power over Ethernet low-power DC circuits, high-bandwidth wireless networks such as LTE and IEEE Proprietary hardware dominates the controller market. Each company has controllers for specific applications.

Some are designed with limited controls and no interoperability, such as simple packaged roof top units for HVAC. Software will typically not integrate well with packages from other vendors. Current systems provide interoperability at the application level, allowing users to mix-and-match devices from different manufacturers, and to provide integration with other compatible building control systems.

These typically rely on SNMP , long used for this same purpose to integrate diverse computer networking devices into one coherent network. Analog inputs are used to read a variable measurement. Examples are temperature , humidity and pressure sensors which could be thermistor , 4—20 mA , 0—10 volt or platinum resistance thermometer resistance temperature detector , or wireless sensors. A digital input indicates if a device is turned on or not - however it was detected.

Digital inputs could also be pulse type inputs counting the frequency of pulses over a given period of time. An example is a turbine flow meter transmitting rotation data as a frequency of pulses to an input. Nonintrusive load monitoring [5] is software relying on digital sensors and algorithms to discover appliance or other loads from electrical or magnetic characteristics of the circuit.

It is however detecting the event by an analog means. These are extremely cost-effective in operation and useful not only for identification but to detect start-up transients , line or equipment faults, etc. Analog outputs control the speed or position of a device, such as a variable frequency drive , an I-P current to pneumatics transducer , or a valve or damper actuator.

Another example is a variable frequency drive ramping up a motor slowly to avoid a hard start. Digital outputs are used to open and close relays and switches as well as drive a load upon command. An example would be to turn on the parking lot lights when a photocell indicates it is dark outside. Digital outputs could also be pulse type outputs emitting a frequency of pulses over a given period of time. An example is an energy meter calculating kWh and emitting a frequency of pulses accordingly.

Controllers are essentially small, purpose-built computers with input and output capabilities. These controllers come in a range of sizes and capabilities to control devices commonly found in buildings, and to control sub-networks of controllers. Inputs allow a controller to read temperature, humidity, pressure, current flow, air flow, and other essential factors.

The outputs allow the controller to send command and control signals to slave devices, and to other parts of the system. Inputs and outputs can be either digital or analog. Digital outputs are also sometimes called discrete depending on manufacturer. However an additional device can also exist in order to integrate third-party systems e. The installer typically selects one of the available pre-programmed personalities best suited to the device to be controlled, and does not have to create new control logic.

Occupancy is one of two or more operating modes for a building automation system. Unoccupied, Morning Warmup, and Night-time Setback are other common modes. Occupancy is usually based on time of day schedules. In Occupancy mode, the BAS aims to provides a comfortable climate and adequate lighting, often with zone-based control so that users on one side of a building have a different thermostat or a different system, or sub system than users on the opposite side.

A temperature sensor in the zone provides feedback to the controller, so it can deliver heating or cooling as needed. If enabled, morning warmup MWU mode occurs prior to occupancy. This is also referred to as optimized start.

An override is a manually initiated command to the BAS. For example, many wall-mounted temperature sensors will have a push-button that forces the system into Occupancy mode for a set number of minutes. Where present, web interfaces allow users to remotely initiate an override on the BAS. Some buildings rely on occupancy sensors to activate lighting or climate conditioning.

Given the potential for long lead times before a space becomes sufficiently cool or warm, climate conditioning is not often initiated directly by an occupancy sensor.

Lighting can be turned on, off, or dimmed with a building automation or lighting control system based on time of day, or on occupancy sensor, photosensors and timers. A photocell placed outside a building can sense darkness, and the time of day, and modulate lights in outer offices and the parking lot. Lighting is also a good candidate for demand response , with many control systems providing the ability to dim or turn off lights to take advantage of DR incentives and savings.

Lamps with DALI ballasts are fully dimmable. This can save money by using less chilled or heated water not all AHUs use chilled or hot water circuits. Some external air is needed to keep the building's air healthy. To optimize energy efficiency while maintaining healthy indoor air quality IAQ , demand control or controlled ventilation DCV adjusts the amount of outside air based on measured levels of occupancy.

Analog or digital temperature sensors may be placed in the space or room, the return and supply air ducts , and sometimes the external air. Actuators are placed on the hot and chilled water valves, the outside air and return air dampers. The supply fan and return if applicable is started and stopped based on either time of day, temperatures, building pressures or a combination.

The less efficient type of air-handler is a "constant volume air handling unit," or CAV. The fans in CAVs do not have variable-speed controls.

Instead, CAVs open and close dampers and water-supply valves to maintain temperatures in the building's spaces. They heat or cool the spaces by opening or closing chilled or hot water valves that feed their internal heat exchangers. Generally one CAV serves several spaces.

A VAV air handler can change the pressure to the VAV boxes by changing the speed of a fan or blower with a variable frequency drive or less efficiently by moving inlet guide vanes to a fixed-speed fan. The amount of air is determined by the needs of the spaces served by the VAV boxes. Each VAV box supply air to a small space, like an office. Each box has a damper that is opened or closed based on how much heating or cooling is required in its space.

The more boxes are open, the more air is required, and a greater amount of air is supplied by the VAV air-handling unit. Some VAV boxes also have hot water valves and an internal heat exchanger.

The valves for hot and cold water are opened or closed based on the heat demand for the spaces it is supplying. These heated VAV boxes are sometimes used on the perimeter only and the interior zones are cooling only. This adjustment reduces the cooling, heating, and fan energy consumption.

In this system, the interior zones operate as in a VAV system. The outer zones differ in that the heating is supplied by a heating fan in a central location usually with a heating coil fed by the building boiler. The heated air is ducted to the exterior dual duct mixing boxes and dampers controlled by the zone thermostat calling for either cooled or heated air as needed.

A central plant is needed to supply the air-handling units with water. It may supply a chilled water system , hot water system and a condenser water system , as well as transformers and auxiliary power unit for emergency power.

If well managed, these can often help each other. For example, some plants generate electric power at periods with peak demand, using a gas turbine, and then use the turbine's hot exhaust to heat water or power an absorptive chiller.

Chilled water is often used to cool a building's air and equipment. The chilled water system will have chiller s and pumps. Analog temperature sensors measure the chilled water supply and return lines.

The chiller s are sequenced on and off to chill the chilled water supply. A chiller is a refrigeration unit designed to produce cool chilled water for space cooling purposes.

The chilled water is then circulated to one or more cooling coils located in air handling units, fan-coils, or induction units.

Fallen trees on electrical wires and a blown-out transformer left her without power for two days. That was three years ago. This type of unexpected incident left her with no choice but to drive her two children 45 minutes away from home and stay with her sister until power was restored to the neighbourhood. Switchboard operators were flooded with phone calls from angry customers, and service teams had to be dispatched to locate where the damage had taken place. Then it took hours and hours to troubleshoot and repair the actual equipment problems. The entire situation was both costly and stressful. Fortunately, both the utility and its customers like Sarah will not have to relive that experience. The result is that the region is much more prepared to handle extreme weather scenarios. Disruption of service to customers is now kept to a minimum. The utility company can now forecast storm parameters such as high winds and lightning strikes, identifying the areas likely to sustain most damage from an incoming storm, and predict which equipment in the field is most likely to fail.

This article reviews all aspects of embedded software in cars, including operating systems, protocols, development tools and international standards. Until around the turn of this century, there were very few electronic systems in vehicles. That has all changed. Every system is electronic and a variety of design approaches are applicable. Just about every newsworthy development in cars today has its roots in electronics. That electronics is mostly embedded systems and that means that software is a critical issue. The automotive industry is culturally inclined to the wide utilization of standards to an extent not seen in many other industries with which software developers may be familiar. This comes about because, apart from being good business practice to take standards-based approaches to design when possible, the auto industry has a complex supply chain, so compliance with standards is easier to manage than individual, very detailed specifications. Some of the standards that apply to electronic systems in cars not an exhaustive list :. CAN Bus The wiring in cars was traditionally point to point.
