Design, presentation, installation and operation of building energy management systems (BMS, BEMS)

AsiaWatt Engineering Company has designed, presented and launched building energy management systems with the aim of reducing energy consumption in the building sector. Building energy management systems include sensors, actuators and controllers, whose task is to control different parts of the building, and through the central computer, information on variables such as temperature, pressure, humidity, voltage, amperage, or the status and operation of equipment such as pumps, fans, boilers. , chiller, etc., which are measured by sensors and switches, and after analyzing them, sends commands to actuators and motors such as solenoid valves, motor dampers, contactors, etc.

Building energy management systems include the control of the following sections:

• Integrated control and management of building departments
• Intelligent control of engine room and facilities
• Building lighting control
• Building security control
• Fire alarm and extinguishing system
The advantages of these control systems are summarized in achieving the following goals:
•    Energy saving
• Reduction of manpower
• Increasing the useful life of equipment and reducing their failure rate
• Reducing maintenance and management costs
•    Establishing flexible automation for all building functions
•    Optimizing the performance of building systems continuously
•    Ensuring building safety

Technical inspection of the engine room

Considering the significant share of energy consumption in the building sector, which accounts for more than 40% of the country’s total energy consumption, as well as with the government’s move towards eliminating subsidies and realizing the prices of energy carriers, optimization and implementation Energy saving solutions in this sector will be more necessary. Among the energy consumers in the building sector, the heating system has the highest amount of energy consumption, and according to the surveys, about 70% of the natural gas consumed in the country is allocated to the heating of buildings. In Iran, most of the buildings have a central heating system and an engine room, therefore, focusing on the implementation of energy saving measures and reducing energy losses and improving the current condition of the building’s engine room facilities will play a significant role in reducing the country’s fossil fuel consumption. According to the surveys conducted, the engine houses of the country’s buildings are not in a good condition at the moment, the main reasons for which are the non-compliance with the correct principles in the design and selection of equipment, the inappropriate condition of the insulation of the facilities, improper operation, and the lack of a documented maintenance and repair system. And finally, there is lack of sufficient inspection and supervision on the operation status of engine houses. In addition to losses and increased energy consumption, the improper operation of the engine room causes an increase in environmental pollution.

Based on this, one of the most effective measures to reduce energy consumption, reduce the production of toxic gases and pollute the environment, de-peaking the gas network, reducing depreciation and maintenance and repair costs, is the implementation of the technical inspection plan for engine rooms of buildings.

AsiaWatt Engineering Company, while having sufficient experience in this regard and having experienced experts, declares its readiness to carry out technical inspection in the engine houses of the country’s buildings. The technical inspection of the engine room of the buildings is carried out in the following steps:

Checking the engine room components and completing the engine room technical checklist
Examining the existing clarity and correcting and repairing the insulation of the engine room facilities
Checking the state of the design of the engine room and the suitability of the existing boiler and burner
Detailed examination of fuel system components in terms of design, safety and performance
Analyzing combustion products using a gas analyzer and comparing with the standard mode
Accurate adjustment of the fuel-air ratio in the burner to reduce fuel consumption and reduce polluting gases
Checking and correcting the condition of the chimney and installing a barometric damper if necessary
Detailed examination of hot water circulation and transfer systems in terms of design and efficiency
Preparing a report on engine room problems and providing solutions and…

Building energy label

The criteria of the building energy label can be calculated from simple criteria such as the heat transfer coefficient of the outer shell of the building to complex criteria such as the amount of energy consumption of the building. In the country, due to the high cost of fuel consumption, the labeling criterion exceeds the limit of the heat transfer coefficient of the shell and directly targets the energy consumption of the building.

The best way to express the energy consumption of the building is to determine the amount of primary energy consumed, in which the energy consumption is calculated according to the type of energy carrier. In Iran, the classification in the energy label of buildings is based on the amount of primary energy consumed. In existing buildings, energy bills are a method to determine the amount of energy consumption of the building, but in the case of buildings under construction, it is determined by calculating the amount of energy consumption. For this purpose, using the provided instructions, the amount of energy consumed by the building in the heating and cooling sector, hot water consumption and lighting equipment is calculated. Then, by determining the energy consumption index of the building per area unit and dividing it by the energy consumption index of the ideal building, the energy ratio parameter (R) is determined and based on that, the classification of the label is determined. The method of calculation and guidelines for providing energy labels for residential and non-residential buildings has been approved as a national standard in the Iranian Institute of Standards and Industrial Research, and its executive regulations are currently being prepared.
