Abstract

Purpose-Rural residential buildings in China?s cold areas still have large room for improvement in lighting, energy saving and other aspects due to their own development lag. Design/methodology/approach-Taking Zhaoyuan County residential buildings as an example, the spatial elements of residential buildings are quantified, and the variation intervals of each spatial element are determined based on this. Then the standard model of residential buildings is constructed, and the changing trend and related mechanism of heating energy consumption and natural lighting under the change of residential space elements are discussed. Findings-The results show that: (1) In terms of heating energy saving, there is an obvious optimal solution between the window wall ratio of the south facade and the orientation of residential buildings. (2) In indoor natural lighting, all spatial elements show positive and negative correlation without considering glare. (3) Building depth, eave height and plane girth area ratio are the key variables affecting heating energy consumption. Window to floor ratio, building eave height, building depth and plane aspect ratio are the key variables that affect indoor lighting. Originality/value-The research results can provide reference for the energy-saving construction of residential buildings in cold areas.

基于建筑性能模拟的寒区居住空间优化分析

目的——中国农村居民楼?美国寒冷地区由于自身发展滞后，在照明、节能等方面仍有较大提升空间。设计/方法/途径——以招远县民居为例，对民居的空间要素进行量化，并在此基础上确定各空间要素的变化区间。在此基础上，构建了住宅建筑标准模型，探讨了住宅空间要素变化下采暖能耗和自然采光的变化趋势及相关机理。研究结果表明:(1)在采暖节能方面，南立面窗墙比与住宅朝向之间存在明显的最优解。(2)室内自然采光中，在不考虑眩光的情况下，各空间要素均呈现正相关和负相关关系。(3)建筑深度、屋檐高度和平面周长面积比是影响采暖能耗的关键变量。窗地比、建筑檐高、建筑深度和平面宽高比是影响室内采光的关键变量。独创性/价值研究成果可为寒冷地区居住建筑节能施工提供参考。

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
