The importance of preventive maintenance of building facilities
Nowadays, with the development of technology and using equipment with the latest technology in the installation industry, the issue of preventive aintenance of building facilities has particular importance.
The major goals of preventive maintenance of building facilities is to optimize the ability of equipment and devices to achieve maximum efficiency, reduce their breakdown and failure. Also, its minor goals include increasing readiness, increasing reliability, reducing additional costs and downtime.
The strategic goal of maintaining the facility in the building are:
Hence, the characteristics of traditional repairs describes as follows:
The initial cost for purchasing and installation of equipment and systems is a significant which is economically justified only if the lifetime of the device is increased. Currently, many active installation systems in residential and even office buildings do not operate at their appropriate performance level due to disproportionate design problems or poor execution and commissioning. Incorrect calculation of heat and cold load or overestimation and unrealistic calculation (due to the uncertainty of designer’s performance, so-called Over Design), often leads to the purchase of a system that is much higher than the actual building needs, which imposes additional costs on the employer and the system manager in the maintaining process of the engine rooms. Also, sometimes when the heat and cold load of a residential complex is calculated, choosing a device (boiler, chiller, pump, etc.) or using two or more parallel but smaller devices is one of the design arts which in the process of system maintenance reduces the building current costs.
Scientifically and practically, the issue of preventive maintenance involves the use of specialized and trained personnel to perform tasks from the moment of design to the end of the useful life of a system, and this is contrary to the people’s point of view who think that maintenance is an activity.
The most important points that are mentioned to maintain the system of mechanical installations of the building cab be described as follow:
The main criticism of preventive maintenance operations is the high cost of intermittent replacement and scraping of parts in situation where some of them have a significant remaining life. The preventive maintenance program by the facility engineer with shorter intervals requires statistical reliability with increasing the frequency of examination and opening the device and replacements. This method increases the risk of damage caused by the maintenance and repair process. Despite the above, preventive maintenance is the basis of corrective methods for application in most water supply equipment, air conditioning, and etc. What is needed is a method that determines how much and what time, the condition or use of the device or fluid are likely to affect the PM timeline and can be adjusted accordingly.
When planning to clean up and carry out operations, consider a to-do list of equipment that needs to be done on a monthly, quarterly, yearly, etc. basis. Then insert them into the existing equipment maintenance management program, just make sure it can be retrieved by the operator. A comprehensive plan should provide a comprehensive history of maintenance on each piece of equipment as well as modified costs. In the case of preventive maintenance of building facilities, experience shows that we need a good and clear record of service and timing. Putting labels on your equipment is another way to maintain an engineered facility and is an activity that is performed on many different components of central engine room equipment and pump houses. The systems used in the building are the driving forces of all the facilities of the building. Without light, water or heating and cooling, a building would be uninhabitable, so a strong preventive and pioneering maintenance program is not arbitrary; This option must be considered.
