For builders and interested customers seeking for knowledge about residential venitlation units, the current >> eBulletin No. 14 is ready to be downloaded, available in English for the first time. This eBulletin consists of a listing of tested residential ventilation units, tested according to German and European regulations and standards. We from TZWL offer the most comprehensive eBulletin so far - cost-free for planners and builders.
We did not spare any efforts and not only included the new testings standards EN 13141-7 and the German LÃ¼A 21-1 into our listing of tested residential ventilation units, but also provide information about the EcoDesign-Labels, which are obligatory for residential ventilation units sold in the EU. Thus you compare about 200 different units with test results according to German and European standards.
The most important extension of our eBulletin is the inclusion of >> EcoDesign-Labels, colour-coded logos for the efficiency classes A+ to G. With the eBulletin, planners and builders can compare this classification of annual energy saving potential of ventilation units with a multitude of technical characteristics and unit performances.
Ducted residential ventilation units are currently tested according to the LÃ¼A 21-1 in Germany, as well as according to European standard EN 13141-7. We therefore implement these regulations in the lists. Further information about how to read and understand the test results can be found in the explanatory notes - Appendix A.
