Intelligent Building Management System

It's about running all kinds of wires and coaxes through a house to hook anything to anything, computers, printers, tv, etc.

Or it can be having an intricate wireless system. I don't trust wireless as there's always radiation involved. People talk about how low the levels are but I don't trust that.

A true intelligent building management system is one designed to reap what nature gives freely and give regular energy consumption the boot.

Seems interesting and distressing to me that probably in America some people's self images are linked to the ostentatiousness of their resource consumption.

The great lie, "More is more". The great truth, "Less is more".

I worked for Johnson Controls for 10 years, and this type of terminololgy is central to what controls companies put together. I also worked for 1 year as a digital controls installer with another company.

Basically, it costs x dollars to heat or cool, light, and control a building. Largely these are energy costs, but there is a lot more automation that can be accomplished from security systems (door control systems) to point trending and data capture. Intelligent lighting systems use sensors to detect activity, but also operate from a schedule. Air handling systems are scheduled but can be commanded from a a central workstation. Boiler and chiller plants become automated, and technologies such as ice storage for cooling, can be implemented to help displace peak energy consumption from energy companies peak energy costs. (the cost of energy changes through the day, and most office buildings are unoccupied at night, so if you can store energy from night, and use it during the day, your costs will be less, because daytime energy is more expensive)

The building 'envelope' is a perspective on energy management that looks at the total energy inputs and outputs, including infrared sensing of the exterior of the building. It looks at myriad methods and technologies to control and or reduce the losses, and increase efficiencies through automation. There is no simple definition, as it can even included planned service agreements for equipment maintenance, and lighting ballast replacements and light bulb replacements. Treatments can be added to windows to decrease heat loss if heating costs are high, or addtional ventilation if cooling costs are high.

Building management systems have been around since the pneumatic systems were first installed in the the sixties. The founder of Johnson Controls was Professor S. Johnson, and was the inventor of the Automatic Temperature Control Thermostat, in 1895 or so. 'Intelligent' really means that the equipment is electrically controlled, scheduled and able to respond to users presence. Also that motors for pumps and fans have variable frequency drives, which can throttle output of the controlled device to match demand, and therefore optimize the energy usage to actual demand.

Energy Management Systems, or Facility Management systems, or Building Management systems, whatever the individual proprietary companies call their product line, are often accompanied with greener initiatives for conservation and recycling for the building tenants and customers, so the overall effect is a significant savings, and sometimes even tax incentives by the government.

The central workstations have bound graphic systems with live data mapped to the schematic pictorial graphics from throughout the building. This can included fan and pump statuses, various temperatures, pressures, humidities, lighting zones, door status, etc. As mentioned, the systems can also run trends and data reports on any selected device. as suggested earlier, occupancy control is central, and large air handling systems are strategized to the occupancy plan, and Variable air volume systems give metered control to conditioned air production, tailord to actual usage and user preference, instead of a 'large plant' strategy, which is very inefficient. There are dozens of strategies for air, heating and cooling delivery systems, and there is a significant amount of science involved, and increasingly so, more research, as the cost of energy rises.

Nice post !

wonderful post.

Johnson equpment has many applications in china market, so we know it. especially at fire fighting.

in fact, in one words, intelligent building is computer control, it controls every thing centrally which is used to operated by human theirself

Hello Chris,

As a matter of fact your article is a peace of art you knwo what you are saying,

well my name is Mohyee and I used to work with Siemens for 8 years and nearly to join americna company (GridLogix) a new company who si one of th eleaders in protcols translation ( EnNET) using XML, Web service protocols.

GridLogix have a very good relation with JCI, as they did a masive integration project ( 1000 building) in Messouri state.

I hope you may advise me of thier momentum in the Intelligent Building Solution market and as well the future in the industry , does it go that way?

www.dynalite-online.com I work with this stuff nearly everyday. Fantastic. Gloss over the dimming stuff to get to the core of the energy management solutions. Brilliant thing is that once you program it (into each individual bit) no-one can frig with it which here in Bali is a very good thing.

hi,

this concept is totally intergrating a building.it consist of the foll.

*fire alarm system

*access control system

*cctv

*public addressing

*fm 200

*water leakage detection system

*intergrating UPS,PAC,lightening,AHU,HVAC

How about the career opportunities in this field., I got an offer in Dubai as a BMS Engineer. Please give me a suggestions about the growth in this field.

In fact the concept of Intelligent system has been known since 70's era and at that time most of the automation system was applied in factories. Talking about the Intelligent Building system then we should go on to a discussion about the concept of utilizing the rapid development of technologies that we can apply to the Skyscraper Buildings, Commercials, Public facilities, Residential etc. for comfort, safety, security, convenience or simplicity and efficiency.

The keyword of:

• Comfort
• Safety
• Security
• Convenience and
• Efficiency

are being the measurements of how Intelligence the Building is and this can usually be achieved when the entire system being integrated in such a manner so that it become a large sophisticated system.

Here is the simple illustration about it and you may give me feedback in case you find anything is inappropriate..:

• For Conveniences normally a Building provides the good lighting system, air conditioning system, plumbing system, sound system etc. which are designed and installed in such a way so that all people will be happy & feel at home being inside. However, isn't that wasteful if in unoccupied rooms those entire facilities keep functioning as well as the lights that keep turned on even though it has brighten by the sunlight? The solutions for this inefficiency could only be overcome with IB system by installing the presence detector, light sensor and window or door sensor.
  
• For maintaining the security for both occupants and the valuables, the security system must be designed in such a way starting from the access gate to every entrance & exit doors so that anyone passing through gate and any doors is continuously recorded without having to be disturbed by officials inspection that sometimes exasperate and time consuming. In the IB system, each of the vehicles got an ID that within the distance of communication; system will automatically provides access and register it. All valuables got IDs so any attempt of sabotage or destruction of any equipment can be immediately noticed. Everyone in this Building has their own Security Access Level; it can be useful for limiting access at each door so that the same door is impassable under certain conditions or at a particular time.
  
• For maintaining the safety of a building with its contents and the occupants, all hazardous prevention system should be designed and installed in such a way for the terrorist threats, natural disasters, fire danger etc. By Implementing of the IB system, all of required sensors for the early warning system are installed & programmed accordingly with its function needs so that any arising threat of danger would be immediately noticed, anticipated and automatically prevented by the system as well as it links to all related parties or agencies via IT to perform the information of the situation and for remote monitoring purpose.
  
• If those mentioned points above using the stand alone system then the result will never be really convenience & sometimes very troublesome. It will be less comfort or even annoying and take pains when you have to do this & that for some simple jobs such as having a meeting for example. With the stand alone system one should go here and there to set up everything in a meeting room, starting from say closing the vertical blind, dimming the lights, turning the air conditioning and OHP on etc. Using the IB system all sequences will be performed automatically simply by a click of a button and the rest all what you do is just conducting a good meeting. Ease of managing the Security & Safety system for comfort & conveniences as well as for efficiency is the bottom line of why IB system is crucial.
• Efficiency is a 'breath' for IB system indeed. Efficiency tends to be proportionally reversed with all of components in that keyword if its system not being integrated or can not be integrated so that the more time consuming, more energy wasted and more inefficiency costs will arise. Thus the substance of IB system as I described here is the solution to overcome those matter. As I always say that in creating something, same thing happen with that to design IB system, the only limitation of creating the most sophisticated system is on our imagination's boundary.

Long before home automation emerged in the market and in the building construction scope of works, Building Management System was already a standard.

A Building Management System is a system that controls, monitors and optimizes building facility's functions and utilities. This system is most commonly applied in large buildings or so commercial establishments enabling full automatic tasks coverage by the building managements whom are the guardsman and technical department in-charge such of the in-house electricians.

Given that we know a Building Management System is a control and monitoring of the building utilities yet what are these functions that a building management system is controlling? In a building it is a must that a CCTV system is installed for security reasons as a regulation by the authorities. HVAC, lighting and security and burglar alarm system, plumbing system, access control, fire alarm and other engineering systems.

A Building Management System comprises and benefits building owners, tenants and maintenance operation personnels for effective monitoring on level of consumptions for running utilities and while for security on the building vicinity's activities and controlling the distribution of the building illumination and ventilation.

Whereas a smart building management system optimizes and corresponds to the use of these facilities with ease and comfort and environmental compliance to the Building Management System standards under the law applied for the Go Green project adopted by the governing authorities in Dubai's projects and developments construction.

In view of the fact which a building management system is a common implementation, the advantages and benefits of a smart building management system by Smart-Bus is more than just a system installed yet is an added value that will provide a cost effective, function accuracy and liability to the so called Building Management System.

Does Smart-HDL Bus work for 110V Power also?

Do you have Dealers in Saudi Arabia to Assist us?

I came across this term on some other blog called Electrical engineering community. There are two articles one talks about the advantages of Intelligent Building management System and other one talks about the disadvantages of this system. I would say its a bit hard to know coz making the building fully intelligent is a bit costly affair and the occupants may not be happy. For your reference i will give you the link for both the articles: My office: a 100% intelligent building ! and Intelligent building: from dream to nightmare!

There is no simple definition, as it can even included planned service agreements for equipment maintenance, and lighting ballast replacements and light bulb replacements. Treatments can be added to windows to decrease heat loss if heating costs are high
