Abstract
There is a great interest in building
information modelling (BIM) and energy
saving worldwide. In reality, however,
insufficient studies have been conducted
on the development of design methods
to perform energy performance analysis.
Thus, there is a problem that it is difficult
to objectively obtain reliability in energy
performance assessment of architectural
designs such as scale and size of
buildings.
them in design. To this end, this
study analysed the correlation with
energy performance using only basic
architectural design elements with mass
buildings. This has the advantage of
establishing more free mass design mass
design considering energy performance
even if design and main structure are yet
to be determined.
In addition, the energy performance
analysis is considered as a different field
from eco-friendly design methods. There
is also the problem that low-carbon
design methods are more dependent
on thermal insulation performance and
heating ventilation and air conditioning
(HVAC) systems than on original design
methods. Introduction
Currently, there is a growing awareness
of environmental pollution in the
whole field of architecture, and there
is a continuously increasing interest in
green building and low-carbon design
methods. According to the World Energy
Statistics (Enerdata), it is a fact that the
Republic of Korea is urgently required to
reduce energy consumption across all
industries as the world’s eighth largest
energy consumer in 2015.
In order to solve this problem, this study
aims to develop design methods capable
of considering energy performance
from the early design stage. Designers
are required to intuitively understand
the results through energy performance
analysis using BIM tools and to reflect Moreover, according to the Korean
Statistical Information Service (KOSIS)
in Statistics Korea, buildings account
for approximately 9.5% of the overall
energy consumption. Although the
increase in energy consumption showed
a decreasing trend from 2010 to 2015,
