ENERGY AUDITING FOR CHILLER SYSTEMS MAXIMIZING PERFORMANCE AND MINIMIZING WASTE
23 - 24 JULY 2026
16 CDP Approved by ST
COURSE INTRODUCTION
Chilled-water plants can account for a substantial share of a building's energy use, making reliable measurement and analysis essential to improvement. This programme guides participants through a practical audit of chillers, pumps, water-distribution systems and air-handling equipment. Using operating data, refrigeration-cycle analysis and electrical measurements, participants learn to identify performance gaps, evaluate energy-conservation measures and prepare a credible improvement plan with reference to ASHRAE guidance and Malaysia's Energy Efficiency and Conservation Act.
COURSE OBJECTIVES
By the end of this programme, participants should be able to:
- Define the scope, data requirements and performance indicators for a chilled-water-plant audit.
- Identify the principal chiller, pump, water-distribution and air-handling system characteristics.
- Analyse refrigeration-cycle, temperature, flow and electrical measurements.
- Compare actual operating conditions with design intent and relevant performance guidance.
- Identify and prioritise practical energy-conservation measures.
- Prepare audit findings, savings estimates and a post-audit monitoring plan.
WHO SHOULD ATTEND
This programme is suitable for energy and facilities managers, HVAC and maintenance engineers, building-services professionals, technicians and operators responsible for chilled-water-system performance, energy audits or efficiency improvements.
