Abstract:
In managing energy in buildings, a greater focus has been given to the HVAC system as it generally consumes more than 50% of total energy usage in buildings. Proper maintenance Had been identified as a significant factor to improve energy efficiency of HVAC systems. For instance a proper maintenance plan can save 5% -20% of energy bills without a significant capital investment. Thus, the research aims to develop a maintenance strategic plan to improve energy efficiency of HVAC systems. Survey technique was adapted to collect data on HVAC system failures, impact of failures, frequency o each failure, significance of causes for failures, and HVAC maintenance requirement to ensure efficiency. A statistical analysis was carried out to develop a maintenance a strategy plan. Maintenance strategic is proposed by using the preventive and predictive maintenance strategy. This proposed plan may be useful for building managers to manage energy by adopting efficient maintenance strategies.
