ABSTRACT
In China, REC (residential energy consumption) is the second largest
energy use category (10%) following the industry. To fulfill the Chinese
government’s commitment that Chinese CO2 emissions would peak in
2030, as a result, improving the energy efficiency and reducing the emissions
from the building sector is significantly important. A survey, in the form of a
questionnaire, of energy consumption and thermal situation in different
residential building types (detached house, multi-story building, high-rise
building), was undertaken in three cities (Shanghai, Hangzhou, and Changzhou)
in hot-summer and cold-winter regions, these three cities were selected to
represent the most flourishing economic provinces. This region in China was
selected for the evaluation of EETP (energy and thermal performance analysis),
because of its special weather conditions, huge energy consumption (as both
heating in winter and cooling in summer are necessary), and other regional
characteristics. 183 households were sampled and experiments were separately
done in typical examples of three different building types. Systematic evaluation
on EETP for three different residential building types, were put forward to
assess the energy efficiency and thermal performance of three different
building types.
KEYWORDS
