PROPOSAL OF A METHOD FOR ASSESSMENT OF ENERGY PERFORMANCE OF LIGHTING IN RESIDENTIAL BUILDINGS

摘要

This paper aims to present the proposal of a new method for assessment of lighting energy performance in residential buildings, based upon findings and conclusions arised from research results. As the standard on energy performance of lighting in buildings distinguishes i.e. quick (or simplified) method and comprehensive method, to be used for different purposes, the proposed method is intended to fill the gap in assessment of energy performance of lighting in residential buildings by the comprehensive method. Though still simplified in comparison to other building categories, for home lighting the method differs in principle, formulae to calculate the indicator LENI and uses a number of new specific factors to express the efficiency of major light sources and to take into account the character of different rooms at homes. For each of the factors, a table of values are presented in the paper and proposal of energy scale for labelling purposes is missed.
