The Energy Savings Ordinance (EnEV) stipulates the energetic inspection of air conditioning systems with a nominal chilling power in excess of 12 kW. The EnEV is the national implementation of the European Directive 2002/91/EC “Energy Performance of Buildings Directive” (EPBD).

 

The inspection comprises measures for checking those components that influence the efficiency of the system, and for checking the dimensioning of the system in relation to the cooling demand of the building. Factors influencing the plant design are to be checked and assessed. Such influences are, in particular, changes in room use and occupancy, in periods of use, in the internal heat sources as well as the relevant building-physical characteristics and the target values specified by the user with respect to air volumes, temperature, humidity, operating time and tolerances. The efficiency of the essential components is to be determined.

 

The user shall be given advice in the form of concise technical information on measures for a cost-effective improvement of the energetic characteristics of the system, for its replacement or for alternative solutions. The inspector shall document and sign this advice, stating his/her name, address and job title.

 

The deadline for the first energetic inspection depends on the year of manufacture of the air handling system.

 

 

After the first inspection, the system shall undergo recurrent energetic inspections at least every 10 years.

 

By means of the TrueBlue efficiency certificate, robatherm reveals potential for improvement in AHUs, for this program enables you to objectively compare various makes, AHU concepts and components, taking into account ecological and economic aspects.

TrueBlue was developed by robatherm as a sound planning tool allowing interdisciplinary and complete verification, in compliance with EnEV, DIN V 18599, EEWärmeG and VDI 2067, of the overall energy efficiency of air handling systems, including all life cycle costs (LCC).
