| Abstract |
For over 20 years, the Building Energy Efficiency Rating (BEER) system played a major role in the national greenhouse gas reduction goal
and made a substantial contribution to the building sector. However, there is also a demand for improvement from the private sector,
policymakers, and researchers in various aspects involving the rationality of this system, market acceptability, and actual effectiveness of this
rating. In this study, by processing Korea Energy Economy Institute's (KEEI) Household Energy Standing Survey (HESS) micro data, sampled
houses were classified into prototypical household groups with respect to region, residential type, exclusive area, and year of construction;
typical fuel and electricity consumption for each group was then calculated. The EER ratio of relative energy consumption of each household
to the energy consumption of the prototypical household group was calculated. By expressing all the EER values of a certain group as a
cumulative frequency distribution graph, a curve-fitting formula for each prototypical household group was derived. Using this formula, the
energy efficiency rating of an individual building can be expressed as energy saving or its efficiency rate compared to the prototypical
consumption and percentage within the group. This rating method informs the building's energy consumption level easily and makes it easier
for the general public to recognize it; therefore, contributing a lot to green building design and construction. |
