ABSTRACT

This study simulates various residential housing construction scenarios, including improved and standard fibro, brick veneer, double brick and fibro with improved flooring. The total heating and cooling energy requirements for each scenario are simulated with a computer program to determine which one is most energy efficient. In the simulation models, construction types and passive solar and energy efficient design strategies (PSEEDS) were varied while other parameters such as wall and roof thickness, windows sizes and general layout were kept constant. The study shows that a standard fibro house had the highest cooling and heating energy requirements (30,721 kWh/yr). The improved reverse brick veneer house had the lowest energy requirement of 9,628 kWh/yr. Amongst all the construction scenarios, the total energy required for cooling was higher than that required for heating. The results show that improved brick veneer, reverse brick veneer and double brick houses have the lowest net energy requirements for heating and cooling compared to the corresponding standard houses. The results indicate that the thermal mass (measured by R value) and PSEEDS incorporated in the construction have significant impact on the energy consumption. Incorporating these design features in the construction of a house can reduce the heating and cooling energy requirements by as much as 69%.

摘要

本研究模拟了各种住宅建筑场景，包括改进和标准的纤维、砖饰面、双层砖和带有改进地板的纤维。每个场景的总加热和冷却能量需求通过计算机程序进行模拟，以确定哪一个最节能。在模拟模型中，建筑类型和被动式太阳能和节能设计策略 (PSEEDS) 发生变化，而其他参数，如墙壁和屋顶厚度、窗户尺寸和总体布局保持不变。研究表明，标准纤维房屋具有最高的冷却和加热能源需求（30,721 千瓦时/年）。改进后的反面砖贴面房屋的能源需求最低，为 9,628 千瓦时/年。在所有的施工场景中，冷却所需的总能量高于加热所需的总能量。结果表明，与相应的标准房屋相比，改进的砖砌单板、反面砖单板和双层砖房屋的供暖和制冷净能源需求最低。结果表明，热质量（通过 R 值衡量）和建筑中加入的 PSEEDS 对能源消耗有显着影响。将这些设计特点融入房屋建设中，可以将供暖和制冷能源需求降低多达 69%。结果表明，热质量（通过 R 值衡量）和建筑中加入的 PSEEDS 对能源消耗有显着影响。将这些设计特征融入房屋建设中，可以将供暖和制冷能源需求降低多达 69%。结果表明，热质量（通过 R 值衡量）和建筑中加入的 PSEEDS 对能源消耗有显着影响。将这些设计特征融入房屋建设中，可以将供暖和制冷能源需求降低多达 69%。
