Abstract With the relevant requirements of energy-saving and green buildings put forward by our country, carrying out the building energy consumption analysis is the premise and foundation of implementing energy-saving improvement of the existing buildings. Nowadays, modern office buildings, whose energy consumption structure and proportion are relatively stable, are widely used. The energy review work of an existing office building in severe cold region is carried out. Investigation and statistics on the general situation of buildings, the general situation of energy consumption and water system consumption and the total energy consumption are implemented. Based on the audit, the energy consumption situation and characteristics in a certain year are analysed. According to the characteristics of energy-using structure, the energy-saving potential of buildings is analysed, and the reasonable energy-saving opinions and suggestions are proposed to provide theoretical support for the energy-saving management of office buildings in severe cold areas.

Double Skin

An actual office building with ventilated double-skin facade (VDSF) in cold region has been studied for researching the opening or closing performance of VDSF on the airflow window in winter. In the daytime of winter, airflow window of external facade should be closed, and airflow window of internal facade should be open, according to which the indoor temperature can be kept at a comfortable level effectively, and the purpose of reducing the indoor thermal load and the building energy consumption of air conditioning can be reached. The research also provides the best time of the airflow window of internal facade to open and close. If one directly applies the analysis of experimental results to guide the construction of VDSF and other energy-saving design of buildings, it can provide a reliable reference for similar projects.

The energy saving of temporary buildings used heat-reflective coatings in cold region has been paid growing attention. Surface temperature and energy consumption were calculated by the temporary office building and factory building in Beijing. The buildings are color steel plate structure in this paper. The roofs and exterior walls of buildings were painted with heat-reflective coatings. The general solar reflectivity of roofs and exterior walls were about 26% and 22%; after the application of heat-reflective coatings the reflectivity increased to about 84% and 72%. Results demonstrated that the roofs have the best cooling effect, with the average surface cooling reaching 23.32°C in summer. The estimated energy savings of roof was about 9.95Wh/m2 per day and the energy consumption reducing rate was up to 67.7% in summer. Considering the energy consumption increased in winter, heat-reflective coatings were only strongly advised to paint on roofs in cold region.
