Energy Efficiency Research On Rural Dwellings In North Shandong

The rural economy developed and people's life became richer. Then the establishment of rural residence increased and energy consumption increased rapidly too. Meanwhile, people pursued big space in residence so that the rural residence became larger and larger in length and breadth and the layer height became larger and larger as well. For the low education level of the farmers, there being two big problems in rural residence's energy efficiency: the energy consumption is quite high and people know little to energy efficiency in rural residence.Through investigation to the actuality of rural residence and the energy efficiency level in North Shandong, acquaintance to rural residence's layer height and buildings' energy consumption and measures to the interior and exterior air temperatures respectively in summer and winter, the author found the influence to rural residence's temperature in different layer height. Meanwhile, by simulating the interior fundamental temperature to different rural residence with different layer height with the software DeST-h and combining with the measuring temperature, the author elicited the energy efficient and economic layer height should be 3.4 meter.Analyzing from the layer height relating factors, the author found out the deficiencies existed in rural residence's energy efficiency in North Shandong were mainly four: The increasing layer height results in increasing building cost;The energy consumption in heating and refrigeration increases;The shape coefficient in buildings was hard to control;Increase in residence's planning area.Through analyze to all these influences the author found out the energy efficiency measures in address selection, energy efficiency and economic layer height, courtyard plane disposal, selection in building type, application in solar energy, heat preservation and insulation to enclosure.In nowadays with comparatively lack in resources, depravation in natural environment, the most important thing in constructing new country is to save soil, energy and resources! Hope this paper can afford a reference-worthy layer height in constructing an "energy and soil saving type" rural residence and contribute to the energy efficiency design of rural residence.
