Factors that impact the energy demand in the building management systems


Building Management systems are gaining wider acceptance today owing to the major benefits that they provide. One of the reasons behind it is the efficient use of energy.

AAG Engineering Technologies have building management system as one of the expertise. The core strength of our BMS lies in the methods to save energy.

Our approach towards building an efficient BMS revolves around automation, and the control to determine whether energy is applied efficiently in the building for the following areas.

Here are the factors that impact the energy demand in the building management system

  1. Outdoor climate: The outdoor climate has a huge impact on the amount of energy consumed. If the outdoor climate is too cold, the amount of energy required by that building management system to heat and maintain the temperature would be too high. Similarly, even if the climate is too hot the amount of energy required would much more.
  2. Building shell: The building shell protects the building management system user from the elements. The exterior shell is considered and optimized as part of the planning for new buildings. This is to some extent not possible for existing buildings (historical or protected objects) or can only be achieved at the considerable effort in terms of cost and time.
  3. Building technology and energy technology: Even the technology that is used for construction in the building management system many times consumes a high amount of energy. While manufacturing of construction materials, energy is consumed and greenhouse gasses (CO2) are emitted. To save the energy consumption many buildings even have insulation. Energy consumption to manufacture this insulation increases, which in turn increase the amount of “gray energy”. In other words, increased insulation only makes sense where the reduction in energy consumption is greater than the “gray energy” of the applied materials.
  4. Operation and maintenance of the building: Day-to-day activities of a building management system requires a lot of energy. Each and every activity right from lightning, water supply, cooling, security and safety systems, power back-up, ventilation are few of these routine activities. Maintaining an up-to-date building may need varying amount of energy depending on the work performed. Like a power-plant would require more energy than a school building even for just maintenance.
  5. Building use and user behavior: As mentioned above, the use of energy vary with the task being performed by the occupants in the building management system. There are high variations also depending on the way users use it. An alert user would save energy and even educate others on it. A coal power plant, for example, situated at two different places and governed by different entities would require a different amount of energy depending on the attentiveness of the employer’s.
  6. Interior room quality: How well a room is insulated, the quality of the material used in construction and the quality of the cooling and heating system utilize matters a lot for the energy being consumed in the building management system. Not to say a fully air-conditioned room would require more units of energy. Even some sections of a building management system utilize more energy as compare to other parts of the building. Like in the hospital, the amount of energy consumed in each and every section won’t be same.

Careful engineering and implementation of building management system, automation and control are the only ways to achieve energy efficient building operation is increasingly gaining wider acceptance.

AAG Engineering proactively takes all possible measures before deployment of building management systems at client’s place. Efficient use of energy is the prime goal of AAG’s building management system!
