Building Management Systems

Table 3.1- Control table of AIS.LLC. It illustrates five internal controls that respectively associate with three control zones: application control, IT general control, and entity-level IT control; four types of control: preventive control, detective control, corrective control and compensating control; three control implementations: manual, automated, and hybrid.

Automation of construction equipment characterized by artificial intelligence, able to implement very complex buildings, interact and carry out instructions from a distance, and installation of building components in precision and speed. Also, the automation of production blocks, standards and prefabrication of various building components may lead to convert the design of buildings into a process of selecting parts. These techniques have also led to reduced cost, the time of execution of major projects and energy efficiency. Figure17 shows the multi-functional building unit, used to raise and enter the components of prefabricated houses into a support structure. Although these standard components, but it will have a multi-variable distribution, to allow for maximum individual expression in interior design and decoration.

A feedback loop is a common and a great tool when designing a control system. Feedback loops take the

An analog input module has a number of interfaces. Typical analog input modules have 8, 16, or 32 inputs. Analog output modules take digital values from the CPU and convert them to analog representations, which are then sent to the actuators. An output module usually has 8, 16 or 32 outputs, and typically offers 8 or 12 bits of resolution. 4.2.3 Digital Input and Output Modules Digital input modules typically are used to indicate status and alarm signals. A specialized digital input module is used for counting pulses of voltage or current, rather than for strictly indicating "open" or "closed." This functionality, however, can also be implemented using standard input modules and functions found in the ladder-logic programming language of the PLC.

The first thing I think of when I hear “Interconnected World” I think of a man with an idea. This man is an architect, who wants to build an enormous building. To start the “building process” (no pun intended) he would need to draw out a plan of what this building is going to look like. Using his art skills he would draw out a diagram of what the building would look like inside and out to make sure it is pleasing to the eye. Then he and an engineer would have to use math to scale out the drawing into real life to make sure the building is structurally sound. He would also need to hire a project manager to watch over the project, and he has the responsibility of making sure the project is running smoothly. To begin the actual assembling of the building he would need to get it approved by the city or county the building would be built in. He would also need a lawyer to sort out the legal and political issues. The engineer has to approve the structure and make sure it’s safe for people to be in. Their would also need to be an accountant to use his math skills for budgeting. Once the county approves all of the legal, structural, and money details, it can start being built. Now we can start the building process. In the building process there will need to be a contractor who specializes in construction management, as well as an engineer to plan and make sure it is perfect before assembled. Once the major structural parts of the building are set, they can begin with

Before we delve into the role of a Project Manager within a Building Information Model (BIM) project and how, if at all, that role has altered, lets step back and understand how BIM evolved.

For the control unit to perform its function it must have inputs that allow it to determine the state of the system and outputs that allow it to control the behavior of the system.

To start with, this self-reflection is consisted of two parts, the first part is majorly related to the lecture experience that help me redefine the Building Information Model (BIM). While the second part is about the experience and knowledge that enhance my knowledge about the BIM enable services provided for Facility Management (FM) maintenance and operation.

Products for smart homes will start to see a big growth in the upcoming years thanks in part to the progression of the mobile network infrastructure. Newly developed applications cloud services are setting the stage for a more sophisticated home monitoring service. Because of opportunities like this, is the reason why a proposal for a business architecture supporting Smart Homes, Inc is being submitted. The main focus of this proposal is the smart home thermostat. Along with the product, the proposal will outline a registration system responsible for collecting and storing smart home thermostat information. This proposal will provide suggestions for

In conventional control systems, control signals are sent over the loop using analog or digital technology whereas in modern control systems, the control loop is closed through a real time communication network by T. C. Yang et al. [1]. The Networked Control Systems (NCSs) are the distributed control systems in which the system components (sensors, actuators and controllers) are connected by communication networks [2]. One

In our case we had to re-specify our goals in relation to data we had obtained.

In Malaysia, the idea of a specific and systematic facility audit for effectiveness, efficiency and performance is in early stages (Musa, 2012). The awareness level from the society is very low. The costly repairs and maintenance may be done as a routine practices, but when the economy is booming only emergency maintenance and repair is attempted (Musa, 2012). (Zunguzane, Smallwood, & Emuze, 2012) added that, the damages and costly repair works are the causes from the improper building maintenance. This has shown us that the main concern was not executed for the maintenance works for the available facilities in Malaysia.

In the presentation we demonstrate the attributes of the Proportional (p), Integral (i) and Derivative(d) controller.

The most commonly used type of controller for many applications in industries is the PID controller. It owns very simple structure and has strong performance across a wide range in the condition of operation. PID controllers are the most suitable type of choices if there is no complete knowledge of the system.
