Hi,
How should the minimum efficiency of HVAC equipment produced and tested for European market be treated in relation to ASHRAE 90.1-2010? The minimum efficiencies given in ASHRAE are tested mostly according to AHRI procedures, but in Europe different procedures apply - mostly EN 14825, and HVAC equipment shall meet the Eco-design Directive 2009/125/EC requirements.
However, how can I make sure if i.e. the VRF unit selected for my project and tested according to European standards, meet the minimum requirements set by ASHRAE 90.1-2010?
Thank you,
Michal

Ideally you could compare some sort of equivalency between the standards. I would say if the equipment meets a very similar testing protocol in the EU then it should be considered equivalent. If you have any doubt about a particular piece of equipment it is a good idea to provide a narrative explanation for the reviewer if the values you enter are less than the 90.1 values for efficiency.
