RETRACTED: A developed procedure to predict annual heating energy by heat- and energy-recovery technologies in different climate European countries

This article has been retracted at the request of the co-authors because they testified that they were included as co-authors without their consent, and that they were dissatisfied with the contents of the paper after discovering the publication. The work described in the paper itself was based on the same methodology and data reported in a reference the author cited, Applied Energy 151 (2015) 3240, http://dx.doi.org/10.1016/j.apenergy.2015.04.022 of which the author was a co-author, and the paper reported the results when applying the method to a different set of climate data. The paper was considered to be only a marginal advance in terms of academic value.
