Five years later he proposed that maintenance should be a new culture for the nation and thus increased the budget for maintenance expenses from RM million to RM 4. In the National Asset and Facilities Management conference was held and this provides a solid groundwork for Total Asset Management which was implemented in all government buildings two years later.
This study gives attention to the maintenance of buildings at Institutions of Higher Learning in Malaysia. Reports from researchers have shown that the universities buildings were not maintained properly.
The conditions of the buildings reported by the researchers include disrepair, decay, deterioration and unfitness of the universities buildings.
However, by consistently implementing the Total Asset Management practises, the situation could change and the buildings could be habitable for many years to come.
Building Maintenance Management in Malaysia — History of building maintenance initiatives in Malaysia only began in as mention in the report of Second Malaysian Plan, - In, Nazaruddin et al. On the side of the government the Pekeliling Perbendaharaan Kerajaan Bil 2 Tahun Government Monetary Circular No 2 Year stated that the fund for maintenance has been increased from year to year.
In the same report there was also a comment about the school community and their readiness to maintain the school building before the process of restoration are done.
It was reported that they did not have technical knowledge needed to fill maintenance form and the school community has also failed to follow the procedure and standard of Malaysian school building. In , Paijan et al.
The contributing factors that were identified include the execution of work that was not up to the expected standard, insufficient Planning and control as well as insufficient budget and malpractice in the financial management. Muhammad Hamid opined that maintaining school buildings in good condition through preventive measures make sense for academic, health as well as economic reasons.
Building Maintenance in Malaysia to current Table 1. Year Issue Building maintenance was highlighted in Malaysia Second Malaysia Plan Government increased maintenance budget according to Government Monetary Circular No 2 Year Complains being raised about accidents, damages and losses due to malpractice of building maintenance management and negligence as stated in Government General Circular No.
One of the root causes of the problem is the lack of an understanding of the maintenance management process among school administrators as such it hinder the schools from designing a good maintenance programme Hamisah Hafni High priority must be put in it especially in maintenance cost allocation Hashim Control measures need to be available and implemented when undertaking the maintenance activities Hashim The first casualty recorded related to building maintenance failure when a teacher at Sekolah Jenis Kebangsaan Keat Hwa who was killed when the rotten wooden plank of the 1st floor balcony gave way and he fell to his death.
The Prime Minister of Malaysia says that it is very common to see that most government buildings were not regularly maintained because most faults cannot be distinguished at their early stage Utusan Malaysia. Fungi infested general hospitals in Kulim and Johor. The Prime Minister has suggested that the Public Work Department needs to prepare building maintenance guidelines in order to identify any damage from the early stage also reported by Utusan Malaysia.
The objectives of this policy are creation of assets to meet delivery systems, documentation of asset information, adoption and monitoring of Total Asset Management Adnan. In year repair and maintenance works constituted 16 percent of the total Malaysian construction output CIDB The leaking of the piping system at Parliament Building Utusan Malaysia. The Ministry of Housing and Local Government received between and maintenance complaints each year over the last five years Chuan The Government Total Asset Management Manual TAM has been implemented as to improve the current procedure which is one of the strategic planning and direction of 10th Malaysia Plan for "Quality of Life of An Advanced Nation".
A systematic, comprehensive and integrated asset management approach has to be created as an ongoing effort towards improving the delivery of the public service sector Government of Malaysia.
As reported in the JPAK official website, the committee are in the midst of undertaking a project to develop a specific system to manage all immovable government assets to be practised by all ministries.
JPAK was intended to publicize and promote the guideline documents which were developed to be used in every aspect of asset management by various government ministries and agencies. A year later, Ramly noted that the lack of maintenance knowledge on the part of building managers in Malaysia and inadequate building inspections could result in problems with implementation of maintenance works, which could cause deficiencies in decision making of maintenance cost.
He also confirmed that allocation of maintenance budget must refer to the complaints made by the building users. While in health and safety aspect related to building maintenance Ramly and Hashim mentioned that high priority must be given to it especially in maintenance cost allocation. These wonderful buildings are indication that we are entering into a new dimension; an image to the Government therefore must be best maintained.
Hamisah wrote that one of the root causes of the problem is the lack of an understanding of the maintenance management process among school administrators which in turn hinder the schools from designing a good maintenance programme. Hashim on the other hand stated that, control measures need to be available and implemented when undertaking the maintenance activities.
The first casualty recorded related to maintenance failure was in when a teacher at Sekolah Jenis Kebangsaan Keat Hwa was killed when the rotten wooden plank of the 1st floor balcony gave way and he fell to his death.
Avoid sandblasting as this may leave permanent stains on the wall. For regular cleaning of sand and dirt. A high pressure water spray can remove dirt and stains from exterior walls. Solvents or paint strippers can break down paints. Ensure ground slopes away from building foundation and water drains away from the foundation. Cleaning graffiti may sometimes require repainting.
Consider thermal improvements and look for possibilities to add exterior insulation or cavity insulation to under-insulated walls. The following Semi-Annual Foundation and Wall Inspection Log is provided for you to incorporate into your own Guidelines and working documents. Exterior Wall Retrofit Opportunities Weatherproof any exposed wood. Mold or fungi formation and wood rot are obvious signs of moisture problems.
Anti-graffiti sprays are available that can be applied over the existing finish to aid in the removal of future graffiti. The spray creates a layer between the graffiti and building surface. Other signs to look for include: Exterior Wall Preventive Maintenance Perform routine inspections to identify moisture control problems before they cause damage. Immediately report any leaks or problems to the building superintendent.
Room Seattle. Cracks in foundation or wall finishes. Washington Building Name: Purpose of inspection: To improve and maintain the durability of the building. Maintenance practices depend upon the specific type of roof at the facility. One of the most important aspects of a maintenance program for roofing is record keeping. This area should be checked for loose or missing fasteners or flashing.
Cap flashings are metal or other covers at terminations. Penetrations such as pipes. Keep a detailed record of all roof work completed as well as a roof-specific bi-annual inspection checklist. Check for structural uniformity when walking over the roof. Roofing The roof provides shelter from direct precipitation and provides a thermal barrier to heat loss in the winter and heat gain in the summer.
The flashing material should be checked for signs of deterioration or building movement. If a green roof is present. Verify adequate drainage. For single-ply roofs. Inspections should occur at least twice a year.
Check the roof membrane for worn spots. Pipe boot flanges should be tightly sealed to the roof membrane. The drain clamping ring should be checked to ensure a watertight seal between the drain and the membrane. Base flashings are at the connections at walls and curbs. Identify and immediately address vulnerabilities to thermal.
Adhesion of sealant inside pitch pockets and membrane adhesion outside should be verified. For builtup roofs. Edge metal at the ends of the roof provides waterproof flashing not true. Perform both preventive and regular maintenance on all building roofs to ensure the safety of occupants. They should be inspected for loose or missing fasteners. Specific repair procedures depend upon the type of roof. Routine inspections will identify problems before they impact energy use.
Penetrations in the roof can cause a myriad of moisture. If repair is required. Roof Inspections Inspection and maintenance procedures specific to a particular roofing product are often available from the manufacturer.
They should have a secure seal with continuous adhesion to the substrate. Maintenance procedures often must be in accordance with manufacturer's guidelines.
Cool roofs will not only lower cooling loads. Debris has a tendency to hold water. Flashing construction and usage are vital. Cool roofs are recommended for low-sloped roofs.
Nature and Importance of Building Maintenance
The end of Part II provides a completed example. Roof Preventive Maintenance The goal of the preventive maintenance program is to decrease the rate of "normal aging" of roofs and drastically reduce the amount of maintenance requests to repair leaks. Make sure that the downspouts are draining properly by water testing them.
Make sure roof edges are secured properly. Roof retrofits provide an opportunity to add considerable R-value to the roof. Clean all debris from the surface of the roof. This should be done in compliance with manufacturer's recommendations. Calculate the energy benefits when considering roof retrofits. Minimize rooftop foot traffic and provide protective walkways where traffic is expected. Trim back any overhanging tree branches away from the building.
For roofs that are still under some form of warranty. Hire a qualified professional mason to perform this work.
Water test any sump drains twice per year. Keep all gutters free of debris. Minor defects left unattended can escalate to cause widespread water damage. Drains will often leak if they are holding water. This includes debris that has gathered behind HVAC units. Check the mortar on chimneys and parapet walls.
Make sure there is proper drainage from the roof and away from the building. Roof Retrofit Opportunities If the existing roofing is determined to be beyond repair. In addition to inspections. It is lightweight and can be both highly reflective and emissive.
System manufacturers and the NRCA have more detailed information. Thermoplastic Polyolefin TPO single ply roofing is an excellent choice for re-roofing. For cool roofs with reflective coatings. Inspected by: Date Inspected: Include any photographs and thermography records in this report. Washington Building: Comment on changes from previous inspections. Verify proper operation of operable windows and window and door hardware hinges.
Immediately address vulnerabilities to thermal. Windows and Doors Windows provide views to the outside.
Verify door and window contacts through security panel. Routinely inspect exterior windows and doors for physical damage and proper seals. Condensation on the interior face of windows is typically the result of extreme temperature differential between the inside and outside and sometimes an indication of excess humidity inside though not always.
Make sure that corners of mechanically joined frames are caulked to prevent water penetration. The operability should not interfere with the HVAC system. It is critical to ensure that windows are functioning optimally and that related problems are minimized through proper maintenance.
Identify and address windows that are wet on the inside. Keep weep holes—used to drain any moisture that gathers between storm and primary windows—clear. Adjust location of security contact sensors as required to ensure full perimeter sealing. Clean frame surfaces. Window and Door Inspections Close windows and doors during the mechanical heating and cooling times. Never use a high-pressure spray nozzle when rinsing windows. Condensation within the airspace of dual-pane windows is indicative of a failed seal.
Windows should be checked for air-tightness. Perform both preventive and regular maintenance on all exterior windows and doors. Verify that exit or other doors intended to be self-closing operate properly. If required. Keep sill and track areas clean and free of dirt and other debris. Window and Door Preventive Maintenance Continuously check for air infiltration through doors and windows. Reports of drafts also may be an indication of a problem. Check that window and door head flashing and window sill drips are clean and clear of paint accumulations.
Window and Door Cleaning! Evaluate the possibility of improving the envelope through careful and limited use of glazing and increased wall insulation values.
The following Semi-Annual Window and Door Inspection Log is provided for you to incorporate into your own Guidelines and working documents. Consider the current and future uses of the building and analyze the amount and location of glazing and doors. Recognize that factory applied paint finishes are permanent.
Check weather stripping around doors and windows during the building exterior inspection. New windows provide better weatherization and energy savings for the facility. Water or air leaks. Improvement in controls can also remedy indoor air quality concerns The plan calls for achievement of a percent normalized net reduction in energy use in County buildings and facilities by The plan also calls for the County to produce King County has established an Energy Plan for all county facilities These goals should drive both development of new Significant energy savings can be realized by improving control of HVAC operations and improving the efficiency of the individual system components Achieving best results in energy efficiency The financial benefits of improvements in productivity can sometimes far outweigh the energy impacts necessary to achieve productive work spaces It is important to remember that most buildings exist solely to enable humans to complete tasks The challenge is to optimize occupant productivity with energy savings Create a narrative of the preventative maintenance plan for equipment described in the systems narrative and document the preventative maintenance schedule during the performance period.
CMM systems come with many options and have many advantages over manual maintenance tracking systems. Older buildings may not be equipped with digital controls and could benefit from the installation and responsible use of a Computerized Maintenance Management System CMMS.
A CMMS does not make decisions. It should be noted that the functionality of a CMMS lies in its ability to collect and store information in an easily retrievable format. Most vendors provide this as a service and it is usually worth the expense.
Staff needs dedicated training on input. Systems Narrative that briefly describes the mechanical and electrical systems and equipment including heating.
The indoor environment in any building results from the interaction between the site. IAQ is a constantly changing interaction of a complex set of factors. This is a site-specific decision. Computerized Maintenance Management System One potential strategy to manage this balance includes utilizing specialty software.
Benefits to implementing a CMMS include: Keep these in mind if you are developing your own policies. EA Prerequisite 1: Energy Efficiency Best Management Practices: Proper ventilation consists of a continuous supply of outside air at a rate that varies based on the space type and occupancy conditions.
Develop building operating plan that includes an occupancy schedule. While a CMMS provides significant advantages. Documentation and Opportunity Assessment o o Achieving a higher level of planned maintenance activities that enables a more efficient use of staff resources.
One of the greatest benefits of the CMMS is the elimination of paperwork and manual tracking activities. Time should be taken to evaluate initial needs and look for the proper match of system and service provider. Conditions to avoid include standing water could encourage mold growth and idling vehicles near outside air intakes or entryways.
Include and clearly state the critical goals of operating and maintaining indoor air quality. Set up the operating parameters and maintenance tasks with these goals in mind. All must be considered to prevent. Optimizing the ventilation can be equally challenging with regard to providing for human productivity and comfort and managing energy use and it should be closely monitored.
Another maintenance goal is making sure that the HVAC system does not become a source of indoor air contaminants. Inspection and periodic cleaning of the system. Then create a list with specific maintenance tasks for the following system components. System Documentation Develop and maintain a documentation and performance tracking system for continuity.
The type of information to be included for each task includes: This is as integral to listing the tasks themselves. Require an energy management plan that follows the King County Energy Plan. Responsibilities Appoint an Energy Manager. Contact your division energy point person. Evaluate whether this should be performed in house or by outside contractor. Communicate the goals to all maintenance staff to provide them with guidance for their day-to-day maintenance decisions. Provide staff with diagnostic tools.
Identify in the plan which system documents are stored. Information to collect and maintain includes: When setting priorities. Prioritize operations and maintenance tasks and adjust schedules to fit available staff time.
Provide the training or skill set involved with each task to best equip the responsible staff. Utilize the King County energy accounting system to locate savings opportunities and to track and measure the success of energy-efficient strategies.
Indicate the responsible staff position for each maintenance task. Additional Factors: Develop a space use-based operations schedule and adhere to it. At best. Evaluation Task List and Schedule Require service contracts that support sustainable building operation. Record the name and affiliation of the person performing the work and the date of response.
At worst. Investigate opportunities for automatic controls. In addition to regular inspections. Stay current on routine maintenance practices. Occupant devices range from desk lamps.
Retain records for at least three years. That audit plan should cover the following: This part of the plan should describe work required to evaluate the following performance characteristics: Example steps to deal with external factors include: Negotiate an agreement with all occupants where they can choose from a variety of energyefficient devices to suit their needs. In exchange, reduce the zones' or building's heating or cooling to a lower level.
Use a pilot program to identify individual devices that work. Set guidelines for employees regarding personal plug-in devices. Allow occupants to self-regulate temperature within a predetermined range through better access to vents and thermostats. Look for low-cost or no-cost system modifications, such as changing operation procedures or automating system settings.
Air Delivery Systems Packaged Air Conditioning Systems Replacement of packaged air conditioning units is not usually cost effective based on energy efficiency alone, but if units are close to the end of their life then early pre-failure replacement may make sense. At time of replacement it is important to seal and insulate ducts and check for airflow constrictions. It is also critical to perform cooling load calculations to check whether a different capacity is appropriate: Packaged air conditioning systems are exposed to outdoor elements and require regular maintenance to ensure efficient operation and reliability.
Check for refrigerant leaks, and if found, fix immediately. Refer to the manufacturer's recommendations for each piece of equipment, modify the maintenance tasks as necessary, and include frequency requirements. Fan Coils and Unit Ventilators These units consist of a fan and one or two coils. In some cases a single coil is used for both cooling with chilled water and heating with hot water. In other cases the unit has two coils, one for cooling and the other for heating. These units also include filters and may have outside air economizers.
Reduce the supply fan minimum speed setpoint. Often this is set higher than necessary due to the default settings of the variable speed drive. Check with fan and drive manufacturer for actual limits.
Analyze space use to determine best setting or strategy for conditioning i. Maintenance of fan coils and unit ventilators notably filter changing and cleaning is similar to Packaged Air Conditioning Systems, described above.
The amount of air supplied to each zone is controlled by a damper within a terminal unit VAV box. These dampers, one for each zone, vary the airflow to maintain the space temperature setpoint. The supply air temperature leaving the air handler is held relatively constant, but is usually varied within a limited range "reset" either automatically or manually depending on the amount of cooling required. Each VAV box usually has a minimum damper position or minimum airflow rate if the box contains an airflow sensor that ensures adequate ventilation is provided to each space.
If a zone requires heating or has low cooling loads, then too much cooling may occur at the minimum airflow rate. Therefore, many VAV boxes include reheat coils, either hot water or electric, that increases the temperature of the air supplied to the zone to prevent overcooling. As cooling loads drop and the VAV box dampers close, the total supply air flow through the central fan also drops.
Without any controls, the pressure within the supply ducts would increase. To save energy, the central fan is usually controlled with a variable speed drive or inlet guide vanes to maintain a constant pressure within the supply duct. Therefore, as the VAV boxes close down, the central fan speed will drop or the inlet guide vanes will begin to close.
VAV systems typically have either a chilled water coil or a refrigerant coil to provide cooling. Heating may be from a hot water coil or a gas furnace, or in many applications, electric resistance heating may be applied at the VAV box called terminal reheat. The appropriate list of maintenance tasks varies depending on the type of cooling and heating and on the type of control system. Older systems often have pneumatic controls, which use the pressure in compressed air lines to control dampers and valves.
Newer systems typically have direct digital control DDC systems that use electrical connections between sensors and actuators and a digital controller. Dampers and valves are moved by electric motors. Reduce minimum airflow settings for VAV boxes to the minimum required for ventilation. Retrofit pneumatic VAV box controls with a DDC system including zone temperature sensors and electric damper actuators.
Implement supply air pressure reset controls to save fan energy. Identify "rogue" zones that have either excessive cooling loads, undersized VAV boxes or other control problems that prevent the system from resetting either the supply air temperature or supply air pressure. These zones may not be meeting their temperature setpoints, requiring the supply air temperature to remain low, even though all the other zones could be satisfied with a higher supply air temperature.
Malfunctioning VAV boxes can result in thermal discomfort and fail to prevent buildup of indoor air contaminants. It is important to insure that VAV box minimum settings e. Maintenance tasks should include those listed for Packaged Air Conditioning Systems, as well as: Bag filters are used only in larger air handlers with adequate space.
Other less commonly used products include electronic polarization filters and electrostatic filters. Check with equipment manufacturers or HVAC designers to determine the proper filter system to maximize both filtration and energy efficiency.
HVAC air filters reduce concentrations of particles in indoor air. Clean and wash the filter area while the fans are off. In general. These ratings indicate the amount of particulate removed from the air stream.
Both are also more efficient at removing particles when new. Filtration's first priority is to protect the HVAC system. Both of these types of filters require a small amount of electric energy.
Several types of air filters are used in HVAC systems. Make sure that filters are properly fitted to prevent air from bypassing the filter and check filter seals. Electrostatic filters also called electrostatic precipitators charge the particles as they pass through and collect them on metal plates. This is in contrast to a standard filter. Pleated panel filters usually provide better filtration with lower air pressure loss compared to flat panel filters.
Inspect and replace filters regularly. A higher efficiency filter removes more material. The dust spot efficiency is more common because it has been around longer. Clean components perform better and are less likely to harbor mold or bacteria growth. There are two commonly used filter performance ratings: Use larger filter areas. Select and use pleated panel filters whenever possible. Outside Air Delivery Filters An integrated indoor air quality approach includes outdoor air ventilation.
Turn off fan while replacing filters to prevent debris from entering the ductwork. The electronic polarization filters create a high voltage electrical field to statically charge the particles. Standard low-cost filters provide little benefit in this regard.
They usually do require maintenance to work over the long term. Provide flush out period after installing new flooring or painting. The savings from this "free cooling" can be big. Perform periodic testing of economizer operation and make adjustments or repairs as needed. A small amount of dust on duct surfaces is normal. Check the spread and throw of diffusers to ensure effective air mixing at point of use. Periodically perform a complete duct inspection.
Duct leakage can cause or exacerbate air quality problems and waste energy. It's often cool enough outside for an economizer to be used frequently. Isolate HVAC during construction or remodeling of specific areas. Parts of the duct system susceptible to contamination include areas with restricted airflow. An outside air economizer can be part of any air handler. Wherever practical. Common leakage problems include: Identify if ducts need sealing and whether cleaning is required.
Ensure each section is pressure balanced to ensure adequate flow. Even when adding more equipment and controls.
Enclose work area and tape over or seal all return diffusers within area. Minimize dust and dirt build-up especially during construction or renovation Promptly repair leaks and water damage to keep system components dry that should be dry Routinely clean system components such as coils and drip pans Chilled Water Systems!
Replace standard efficiency with premium efficiency motors for pumps with long run hours. Regularly inspect. Change air filters after completion of work. Some HVAC systems enable this function very easily.
Determine the type of economizer in use and verify proper operation. Problems with leakage and biological pollutants can be prevented through proper installation and ongoing maintenance inspections.
Consider adding a condenser water conductivity controller for bleed-off water. Trim the pump impeller rather than using a balancing valve to reduce flow in constant pump speed applications. Address tasks for chillers. Typical maintenance tasks for chilled water systems should include: Reduce load — eliminate unnecessary loads from the system. Just meet loads — lower steam pressure or water temperature to meet the actual load conditions.
In some systems. Implement a performance monitoring system to verify that controls are properly implemented and to track chilled water plant efficiency. Replace 3-way valves with 2-way valves on cooling coils and implement variable flow control on the chilled water loop. Refer to manufacturers' recommendations for equipment maintenance tasks. Some single pass water may contain contaminants that will preclude its use in boiler make up or other uses. Review chiller sequencing controls for plants with more than one chiller to determine the optimal strategy for efficiency.
Install variable speed fan controls on cooling tower to reduce fan energy consumption. Where single-pass systems must be kept. Hot Water Systems Possible approaches to increase boiler efficiency include: Perform boiler tune-ups once per year using combustion efficiency and emissions monitoring equipment. Identify and implement opportunities for reducing pump power with VFDs or control strategies. Maintenance tasks for hot water systems should include: Preventative maintenance o Boiler Maintenance o Pump Maintenance o Regular inspections o Record keeping o o o Accurate water treatment Blowdown continuously.!
As the level of sophistication increases. Replace three-way valves with two-way valves on cooling coils and implement variable flow control on the hot water loop. Complete a cost benefit analysis before implementing a CMMS system. The analysis should include a review of downtime reductions. Where appropriate. Automate oxygen trim to operate with boiler controls.
Couple these capabilities to allow for condition based monitoring and component energy use profiles. Pressure or temperature settings should be set no higher than required to avoid short cycling. Implementation costs for a CMMS are primarily driven by the cost of software and the cost of data collection.
Turbulence is not cost-effective if the increased turbulence greatly increases the combustion fan horsepower. Consult your boiler manufacturer.
Train and equip staff for this task or hire professionals — large energy and cost waste are associated with mis-tuned boilers and water heaters. The system should be balanced to avoid this. Install turbulators to increase turbulence and efficiency not all systems can have turbulators. Check setpoint versus control point. Verify that minimum condensing pressures are being implemented. Controls are a retrofit option. Ensure controls adequately reflect the actual building conditions and needs. An EMCS can also be used for performance monitoring.
Energy savings will vary depending on how the existing system is being operated. Check controls periodically.

Electrical equipment and appliances in facilities also use significant amounts of energy. Many lighting systems are overdesigned to account for light loss. Whereas Ordinance requires compliance with standards. As lighting systems are upgraded with newly-available lighting technologies.
Building maintenance management
Recycling and disposal plans for used lamps and ballasts.Introduction According to the U. Periodically verify that plant material is healthy and that soil moisture is adequate. The two variables relating to characteristics of the organisation and the building stock can be combined to give the following categories: This normally manifests itself in labour shortages 22 Building Maintenance Management and extended delivery dates.
Most of its output is custom-built and geographically widely distributed. This option is not new as it is a model that has been in use since The estate services section is also responsible for maintenance of buildings and estates for the other divisions. Within the public sector a fresh range of problems present themselves. The combined approaches of RCM produce an integrated maintenance system that maximizes facility and equipment reliability.
Verify that the light meets the task requirements.
