3. Abstract
According to the U.S. Energy Department survey in 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.
