Abstract:
The HVAC system has evolved into a valuable asset that affects a building's performance
in terms of the services it provides. A building fault can be defined in a variety of ways.
Based on personal experience and observation, a building flaw was linked to energy
waste, which resulted in unsatisfactory living conditions. There are a lot of reasons for
this, including faulty control programming, design defects, mechanical degradation, and
occupant behaviour, and etc. This research study intends to recommend the best
practices to reduce the electricity consumption on HVAC system. The factors that impact
on HVAC system is; the technology or system of hvac, users and cost that involve during
operation and maintenance activities. The respondent's information was gathered using
a descriptive survey technique. The target population, there were 60 respondents who
represented all management levels, including facility managers, energy managers, and
mechanical teams. The sample size was 57 respondents. A combination of qualitative
and quantitative approaches will be used in this study in the form of graphs. The findings
suggest that, the Variable Speed Drive (VSDs) controller was able to reduce electricity
consumption, provide maximum comfort, ensure good HVAC equipment conservation
and, most importantly, can save more than 34% of energy consumption
