SYNOPSIS   

The Institution of Engineers Malaysia (IEM) is organizing a technical visit to Vivatel Hotel, Kuala Lumpur, to highlight a comprehensive energy efficiency retrofit project successfully delivered by AL-CO Malaysia Sales & Services Sdn Bhd. The initiative modernized the hotel’s HVAC infrastructure while advancing sustainability goals.

Key upgrades included the installation of two GREE magnetic oil-free centrifugal chillers, providing quiet, vibration-free operation and reduced power consumption. An ECONOWATT ozone non-chemical cooling tower treatment system was introduced, eliminating hazardous chemicals and lowering maintenance costs. A GREE water-source heat pump now supplies hot water efficiently, reducing reliance on conventional heating and carbon emissions. Additionally, chiller plant controls and variable speed devices (VSDs) optimize energy use by matching motor speed to actual load demand.

Post-installation monitoring demonstrated a 32% reduction in monthly electricity consumption, translating to estimated savings of RM 77,954.10, with overall HVAC system savings reaching 47%. The project also reduced maintenance frequency, enhanced system reliability, and delivered positive environmental impacts. This visit offers participants valuable insights into practical applications of advanced HVAC technologies, sustainable water treatment, and renewable energy integration in large-scale facilities.


NOTE

•   The visit is strictly limited to only forty (40) participants registered.
