THE LEK-CONCEPT AND ITS APPLICABILITY FOR THE ENERGY ANALYSIS OF COMMERCIAL BUILDINGS

Some recent efforts - particularly in the European context - have prov ided simple-to-use methods to describe and prescribe the overall heat transfer coefficient of building envelopes of small-scale heating-domi nated buildings. One approach suggests the use of the so-called LEK-di agram (Line of European K-values) to establish a relationship between building geometry and the mean heat transfer coefficient of the buildi ng envelope. This paper examines the potential of utilization and the problems in development of similar - albeit extended - approaches in t he more complex context of cooling-dominated buildings.
