What the rules require
EU ecodesign and building directives are raising the minimum efficiency of ventilation and heat-recovery units, making built-in recovery standard for new systems.
Impact on specifications
Equipment sold into the EU must document recovery efficiency and leakage limits, favoring certified plate and wheel cores with verified performance.
Implication for buyers
Specify cores with test-backed efficiency data and comply early; non-compliant units face restricted market access.
