Abstract
A Building Management System (BMS) is a computer-based control system installed in buildings that controls and monitors the buildings mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. The purpose of BMS is to automate, control, monitor & optimize buildings facilities, mechanical, and electrical equipment for comfort, safety, and efficiency. As a core function in most BMS systems, it controls heating and cooling, manages the systems that distribute this air throughout the building (for example by operating fans or opening/closing dampers), and then locally controls the mixture of heating and cooling to achieve the desired room temperature. A secondary function sometimes is to monitor the level of human-generated CO2, mixing in outside air with waste air to increase the amount of oxygen while also minimizing heat/cooling losses. A BMS normally comprises of power systems, illumination system, Heating, Ventilation and Air-conditioning (HVAC) System, security and observation system, magnetic card and access system, fire alarm system, lifts, elevators, plumbing system, burglar alarms, CCTV, trace heating and other engineering systems. Objectives & benefits of BMSEffective monitoring and targeting of energy consumption.Improved systems reliability and life.Effective response to HVAC-related complaints.Save time and money during the maintenance.Central or remote control and monitoring of building.Increased level of comfort and time saving.Possibility of individual room control. Building Management System as an expression, is relatively new (the past 20 years or so); in fact expression has been found only since the introduction to complex electronic devices that is able to keep the data for the purposes of management services such as energy, lighting, heating and so on . Project proposal includes plants like Sport complex, football stadium, swimming pools & green areas. we will use DIALux, AutoCAD and 3D-MAX softwares, design a small simulation for some systems in the building to give a simplified view about the way how it will work. Moreover, apply all the building management system theories to automate and take control over these structures in the most efficient way for occupiers/ business, within the constraints of the installed plant. Project ConclusionIn our project we designed the following:1-Lighting Standards of Football Stadium A lighting system must be installed which meets the needs of broadcasters, spectators, players and officials without spilling light into the environment and without creating a nuisance for the local community. Five classes of lighting systems have been developed. There are two categories that need televised-quality lighting and three classes for non-televised events.Class Name Class Description Class Recommendations Class V International televised Event pitch shall be shadow free/glare free. Class IV National televised Event pitch shall be shadow free/glare free. Class III National game non-televised Event pitch shall be glare free with a minimum of eight poles (recommended). Class II Leagues and clubs non-televised Event pitch shall be glare free with a minimum of six poles (recommended). Class I Training and ecreation non-televised Event pitch shall be glare free with a minimum of four poles (recommended). 2 Street LightThe greater the risk of accidents at night, the more light a road lighting system needs to provide. Where traffic volumes are high, so is risk potential and the danger of collision is even greater where road users differ in speed, size and identifiability, i.e. they include motorists, cyclists and pedestrians. Closely associated with this is the safety of the road itself, which depends on its size, its location and the speed limit that applies. 3 Emergency lighting.When general artificial lighting fails after a power outage, the emergency lighting system takes over. Where there is a risk of accident after a power failure, safety lighting needs to be activated.4 Power SystemThe intent of this chapter is to establish the design criteria and guidelines, which will be adopted for the preparation of the electrical design drawings and specifications for proposed sport complex building. This chapter will also describe the proposed scope of the electrical works in the project, pointing out the type, operation and performance of the electrical systems to be installed within the project.5 Control Panels CircuitsElectrical control systems are used on everything from simple pump controls to car washes, to complex chemical processing plants. Automation of machine tools, material handling/conveyor systems, mixing processes, assembly machines, metal processing, textile processing and more has increased productivity and reliability in all areas of manufacturing, utilities and material processing. 6 Earthing and Lightning Systems: The earthing system will be in full compliance with the IEEE regulations. The TN-S system arrangement will be applicable. This means that separate neutral and protective conductors throughout the electrical distribution will be implemented on the LV distribution system.The need for the protection of plant buildings such as substation, control room, office buildings, work shop, warehouse etc., and cooling towers shall be assessed taking into consideration the exposure risk and the following factors: Use to which structure is put. Nature of its construction. Value of its contents or consequential effects. The location of the structure and The height and the effective collection area of the structure.7 Low Voltage InstallationLow voltage installation does not stand for traditionally 230-volt installations, instead, plans here stands for many equipment operating under this rated voltage.For example, 5 volts circuits are used in lighting control panels when utilize PIR, other when using GLT fire sensor 12 volt is recommended.Here we have various types of electrical plans for the sport complex: Fire Alarm system. TV-installations. Telephone installations. CCTV installations. Emergency installations.8 Lighting Control Lighting controls have traditionally been used to create moods. Today, they are also used as part of a high quality energy efficient lighting system that integrates daylight and electric light sources to provide a comfortable and visually interesting environment for the occupants of a space. Electric lighting controls are appropriate for a wide variety of spaces, from restrooms to large open offices, from conference rooms to classrooms. They can be incorporated with daylighting to provide flexibility, energy savings, and ecological benefits. Although lighting controls are still most commonly used in commercial buildings, they are also increasingly being used in residential applications.
