| Abstract: |
| Buildings in severely cold regions face long and harsh winters, leading to significantly higher
heating demands compared to those in milder climates. To address these extreme conditions, some buildings
adopt earth-covering techniques, which involve using soil as a thermal insulator. Existing qualitative and
quantitative studies on soil-covered buildings at home and abroad are mostly focused on mild climate or arid
and hot regions, while quantitative studies on soil-covered buildings in cold regions are relatively few and
there are fewer studies on the effects of different soil-covering methods on the indoor thermal environments
and energy consumption of buildings. The thermal and physical properties of soil in the study of soil-covered
buildings have already been maturely studied, this paper, on the basis of existing studies on soil-covered
buildings, studies the relationship between the average indoor temperature in winter (referred to as index Ⅰ)
and the average energy consumption in the heating season (referred to as index Ⅱ) under the regulation of
buildings without active equipment and different methods of cladding by adjusting the cladding method, with
the aim of analyzing the influence of each cladding method on the control of indoor temperature and energy
saving, and finding out the effect of different cladding methods on the indoor thermal environment and energy
saving. The purpose of this study is to analyze the influence of each cladding method on indoor temperature
control and energy saving, and to find out the optimal cladding method for energy saving. The study area was
chosen in Inner Mongolia, which is a typical cold climate zone, and buildings with large spaces have high
heating energy consumption due to their large volume. The research objects are selected from the completed
large-space cladding buildings in Inner Mongolia, including Hohhot Sculpture Art Museum, Shengle Ancient
City Museum, Qingshuihe Museum, and Hanshan Ecological Museum, etc. Qingshuihe Museum, which has
complex geographic and climatic conditions and adopts cladding to directly enclose the large space, is
selected as the research object, and the influence of different cladding methods on the energy-saving
performance of the large-space cladding buildings is investigated through the simulation and analysis of
energy consumption. Combining the double judgment study of simulation and field measurement of the
Qingshui River Museum, the study explores the effect of each cladding method on indoor temperature control
and summarize the influence of different cladding methods on the energy saving effect. Taking the Qingshui
Museum as the simulation object, the original simulation model is simplified to extract the simulation
prototype for simulation and analysis in EnergyPlus. The purpose of this paper is to explore the effect of
different cladding methods on the average indoor temperature and average energy consumption of the building
in winter and the heating season, so all the variables in the simulation process are only the cladding methods,
and the settings of other parameters are the same. Cladding methods Referring to the results of existing
research on cladding methods, the cladding methods studied in this paper are categorized into full cladding,
side cladding and top cladding. In addition to analyzing the temperature control and energy saving effects of
each cladding method when applied alone, the temperature control and energy saving effects of different open
surfaces are also analyzed when cladding the top of the building is combined with the other two claddinmethods. The indoor temperature and heating season energy consumption of each cladding method were simulated and analyzed in the simulation platform
EnergyPlus, and the results were compared and verified with the winter indoor temperature measured by the museum and the energy consumption calculated
based on the heating design parameters to verify the accuracy of the simulation analysis. The results show that: the top of the building covered with soil has the
most significant energy-saving effect, and should be considered as a priority; the energy-saving effect of fully covered with soil and open to the southwest is the
second most significant, and should be used as an alternative when the conditions are suitable; the energy-saving effect of the side covered with soil and open to
the southwest of 12 m is slightly inferior to the first two, and should be used as the last option. Based on this study, it is hoped that it can provide some
theoretical basis for analyzing the relationship between the cladding method on the indoor temperature and energy consumption of buildings in cold regions. In
addition, the study has certain limitations. Firstly, the simulation study is based on a single model for a specific climate region, and the applicability of the
conclusions to other climate regions needs to be analyzed in depth. Secondly, the generalizability of the conclusions obtained from the single model is relatively
poor, and although an equal area simulation is introduced at the end of the paper for verification, it is still necessary to continue to make up for the deficiencies
in the subsequent studies. |
