【摘要】：我国农村既有农房量大面广。据统计,2014年我国农村人口6.18亿,占全国总人口45.23%,农房总建筑面积约278亿m2,大部分未采用节能技术。随着农村经济发展,建筑用能需求剧增,既有农房不仅存在大拆大建、浪费资源和破坏环境等严重问题,而且难以满足农民对提高居住功能和质量的需求。制定适应农村特色的既有农房绿色改造效益评价方法是促进我国农房绿色改造急需解决的问题。目前,我国绿色建筑评价标准的对象主要是城市建筑,而农房由于特殊的地域、民风民俗、经济技术条件,改造前后的绿色评判标准与城市建筑有较多不同,若盲目照搬城市建筑绿色评价标准,则会导致水土不服问题。本文首先梳理国内外既有建筑绿色评价相关标准和典型改造范例,通过适应性分析构建适合我国农村特色的农房绿色改造绿色程度评价的功能性指标;其次用功能计算工具,快速得出功能分值,确定该改造农房的星级及各功能指标改善程度;然后建立基于价值工程的农房绿色改造效益评价模型,分别计算农房绿色改造前后的功能和成本系数,得出价值系数;最后进行基于改造功能和改造效益的既有农房绿色改造效益评价。论文选取堰河村土坯房和银杏山庄进行案例研究,结论如下:土坯房改造前后功能值分别为28.74和56.07,改造后属于一星级建筑,改造前后的价值系数分别为0.74和1.22;银杏山庄改造前后功能值分别为38.14和67.93,改造后属于二星级建筑,改造前后价值系数分别为0.8和1.16。评价结果表明:改造后农房基于功能和成本的绿色改造效益明显增加。
[Abstract]:The rural area of our country has a large amount of agricultural houses. According to statistics, the rural population of China in 2014 was 618 million, accounting for 45.23% of the total population of the country. The total building area of agricultural houses was about 27.8 billion m2, most of which did not adopt energy-saving technology. With the development of rural economy, the demand for building energy is increasing dramatically. The existing agricultural houses not only have serious problems, such as large demolition and construction, waste of resources and destruction of environment, but also are difficult to meet the needs of farmers to improve the living function and quality. It is urgent to solve the problem of promoting the green transformation of agricultural houses in our country by formulating the evaluation method of green transformation of existing agricultural houses which adapts to the characteristics of rural areas. At present, the evaluation standard of green building in our country is mainly the city building, but because of the special area, folk custom, economic and technical conditions, the green evaluation standard before and after the transformation is quite different from that of the city building. If blindly copy the city building green evaluation standard, it will lead to problems. This article first combs the domestic and foreign existing building green appraisal related standard and the typical transformation example, through the adaptability analysis constructs the agriculture house green transformation green degree appraisal function index suitable for our country countryside characteristic, then uses the function computation tool, The function score is obtained quickly, and the star level and the improvement degree of each function index are determined. Then, the evaluation model of the benefit of the green transformation of the agricultural house based on value engineering is established, and the function and cost coefficient before and after the green transformation of the farm house are calculated respectively. The value coefficient is obtained. Finally, the evaluation of the green transformation benefit of the existing farm house is carried out based on the transformation function and the transformation benefit. The paper selects the adobe house of Yanhe village and Ginkgo Ginkgo Villa for case study. The conclusions are as follows: the function of the adobe house before and after retrofitting is 28.74 and 56.07 respectively, and it belongs to one star building after the retrofit. The value coefficients before and after renovation were 0.74 and 1.22, respectively, and the functional values of Ginkgo Villa before and after renovation were 38.14 and 67.93, respectively. The evaluation results show that the benefit of green transformation based on function and cost is obviously increased after the transformation.
