Regulations and Standards for Chiller Efficiency By EKG M&E Sdn Bhd

To ensure energy-efficient operation and environmental compliance, chiller systems must adhere to various local and international regulations and standards. These standards set performance benchmarks for chillers and guide manufacturers, facility managers, and HVAC professionals toward best practices in design, operation, and maintenance.

ASHRAE Standards (U.S.)
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) publishes standards such as ASHRAE 90.1, which outlines minimum energy efficiency requirements for commercial buildings, including chiller performance metrics like Energy Efficiency Ratio (EER) and Coefficient of Performance (COP).

ISO 5149 and ISO 16358
These international standards set safety requirements for refrigerating systems and energy efficiency guidelines for chillers. ISO 16358, in particular, focuses on seasonal efficiency metrics like SEER and SCOP to better reflect real-world energy use.

AHRI Certification
The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) certifies HVAC equipment performance. Chillers with AHRI certification have undergone standardized testing to verify their capacity and efficiency claims, ensuring reliability for buyers and regulators.

EU Ecodesign Directive (Europe)
The EU Ecodesign Directive mandates minimum energy performance standards for chillers sold in the European market. It includes strict seasonal efficiency requirements and encourages the phase-out of high-GWP refrigerants.

MEPS (Minimum Energy Performance Standards)
Many countries implement MEPS to define the minimum efficiency levels a chiller must meet to be legally sold. MEPS vary by region and chiller type but generally aim to reduce energy consumption and environmental impact.

Local Green Building Codes
Various jurisdictions enforce energy codes or certifications (like LEED, Green Mark, or Green Building Index) that include chiller efficiency standards as part of overall building energy performance assessments.

Refrigerant Regulations
Regulations such as the Kigali Amendment to the Montreal Protocol drive the shift from high-GWP refrigerants to environmentally friendly alternatives, directly impacting chiller system design and retrofit strategies.
