On April 8, 2026, the group standard “Procedures for Intelligent Control and Energy Efficiency Testing of HVAC Systems” was officially released and came into effect on May 1 of the same year. This standard addresses two key activities—implementation of intelligent control in HVAC systems and energy efficiency testing—emphasizing a system-level performance focus, a foundation in measurable and verifiable data, and traceability of control strategies as a governing constraint. It establishes unified requirements spanning from metering points and data acquisition, through control sequences and parameter settings, to energy efficiency testing methods, indicator calculation, and result evaluation. The implementation of this standard will facilitate verifiable control performance, quantifiable energy savings, and reproducible test conclusions, thereby providing a consistent technical basis for the delivery and acceptance of new projects, energy-saving retrofits of existing buildings, and energy performance assessments. It will also help HVAC controller manufacturers reduce redundant R&D costs and enhance supply-chain collaboration efficiency.
