摘要

背景和目标:根据最新的能源资产负债表,伊朗住宅部门的平均能源消耗约占该国总能源消耗的41%。提高建筑物的能源效率可以减少住宅部门的年度能源消耗,从而减少家庭的能源成本。本研究的目的是利用气候条件分析来评估和优先考虑降低伊朗北部住宅建筑能耗的有效因素。方法:首先对基础工况下的冷热段能耗进行估算,然后进行能耗计算。利用Design Builder软件对得到的结果进行了比较,并制定了能耗优化策略。最后,确定了降低能耗所涉及的一系列有效因素。研究发现:采用LED灯替代传统荧光灯可降低能耗980.4 kWh。此外,改变墙体和吊顶的材料,使用厚度为20毫米的聚氨酯泡沫保温材料,使用双层UPVC窗户,减少了770千瓦时的能耗。采用外活动遮阳篷加内百叶窗后,节能约101.5 kWh。结论:采用Design Builder软件对最常用的材料进行分析。分析是通过综合建筑工程(朝向和立面的最佳形式)来完成的,这是基于该地区消耗普通材料的合理成本。所得结果既可用于评价住宅建筑的能源效率,也可用于在温和湿润的气候条件下创造舒适的生活环境。

Prioritization of the effective factors in reducing energy consumption in a residential building using computer simulation
BACKGROUND AND OBJECTIVES: According to the latest energy balance sheets, the average energy consumption in the residential sector of Iran is about 41% of the total energy consumption in the country. Increasing the energy efficiency of buildings can decrease the annual energy consumption in the residential sector and, thereby, the energy costs of families. The objectives of this study were to evaluate and prioritize the effective factors in reducing the energy consumption in residential buildings in the north of Iran using the climatic conditions analysis. METHODS: In the first step, the amount of energy consumption in the cooling and heating section was estimated in the base conditions, and in the next step, the amount of energy consumption was calculated. The obtained results were compared with each other with the help of optimization strategies for energy consumption using the Design Builder software. Finally, a set of effective factors were determined to be involved in decreasing the energy consumption. FINDING: The results showed that application of the LED lamps instead of the conventional fluorescent lamps could decrease the energy consumption by 980.4 kWh. Moreover, changing the materials of the walls and ceiling, using the polyurethane foam insulation with the thickness of 20 mm, and using the double-glazed UPVC windows reduced the energy consumption by 770 kWh. Energy reduction of about 101.5 kWh was also obtained after external movable awning and internal blind. CONCLUSION: The most commonly used materials were analyzed by the Design Builder software. The analysis was done by integrating building architecture engineering (the best form of orientation and facade) based on the reasonable costs of consuming common materials in the area. The obtained results can be used for both evaluating the energy efficiency in residential buildings and producing a comfortable living environment in a moderate and humid climate.
