- Inspections and audits are performed to different levels in different countries, for example low-cost/ low results in some Member States (MS), more costly and thorough in others (for example in Germany). There is often no practical value in inspections. In most MS, a certified “expert” performs inspections which showcase a positive impact from EPBD. Yet all very much depends on the quality level and the certified “expert”.
- EU Ecodesign Regulation Lot 6 about air handling units provides some guidance in building regulations, and puts good demands on manufacturers and installers. Yet, in some countries not all required regulations are thought through. For example, in Portugal it is now mandatory to have an air handling unit with heat recovery but the potential for recovered energy is too small in this climate, leading to an increased overall energy use in overcoming the heat exchanger pressure drop.
- It is desirable to have energy-efficient, certified and high-quality products in Europe.
- Individual components have a performance grading in European regulations, but not the whole system in which they sit. This is a major problem, as often the overall system does not perform well
