2007, residential energy consumption accounted for 21.4% of the
total annual energy consumption. The purposes of this study are to
analyze the actual residential energy consumption through eQUEST
software; and, collocating with building energy classification
label of different countries, to understand more comprehensively
the causes of continuously rise in global residential energy
consumption and to explore the directions to improve. The study
takes the Sung Shan public housing of Taiwan Taipei as the actual
case for analysis. The building operation schedule is divided into
two types, typical use and seasonal use, and the activity areas are
allocated to residential bedroom, residential single family, as
well as kitchen and food preparation. Apart from the
air-conditioning system, power load is subdivided into interior
lighting, auto refrigeration equipment, cooking and miscellaneous.
The operation schedule of HVAC system is divided into three types,
with 65kBtuh cooling capacity. From the simulation results of the
annual electricity consumption, we recognize that air-conditioning
power consumption from March to October is the highest monthly. And
in six months throughout the year, electricity consumption for
lighting occupies 1/3 of the monthly electricity consumption.
Hence, improvements in energy conservation should proceed from air
conditioning and lighting. Increase of the set temperature, the
addition of high-frequency lamps and electronic ballast are
possible solutions to increase energy efficiency. In addition,
summing up the building energy efficiency standards of different
countries such as the United States HERS, the Europe EPBD, the
Germany EnEV 2007, etc., we can obtain the energy efficiency of
Sung Shan public housing corresponding to the standards, and derive
out suitable building energy-saving strategies for Taiwan.
