Abstract
This study aims to evaluate the economic and environmental performance of
sustainable building technologies applicable to multi-family residential buildings
in Korea. The technologies investigated for the study include; ‘exterior
insulation’, the ‘double envelope system’, the ‘floor radiant heating/cooling
system’, the ‘solar hot-water system’ and the ‘photovoltaic system’. The energy
performance of each technology was evaluated using \“EnergyPlus” as the
simulation program. A sensitivity analysis was conducted in order to determine
the relative influence of each technology in terms of energy consumption
reduction in a sample building. A life-cycle cost analysis of a sample building
designed with conventional technologies was also conducted to compare the
result with the sustainable building technologies. The result of the study
indicates that with the sustainable building technologies, although the initial
investment costs are higher than conventional technologies, are more economical
in terms of life-cycle cost due to the reduction of energy and environmental
costs.
Keywords: sustainable technologies, apartment houses, energy analysis, CO2
emission reduction, life cycle cost analysis, CO2 emission right price.
1 Introduction
Unprecedented global warming in recent days has led to a great concern
worldwide for the reduction of CO2 emissions. In Korea, the housing sector
constitutes about 10% of total CO2 emissions related to energy consumption in
Korea. Since apartment houses account for 85% [1] of the housing market in
Korea, in order to effectively reduce CO2 emissions in the building sector,
