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

这项研究模拟了各种住宅建筑的场景，包括改进的和标准的纤维，砖饰面，双层砖和具有改进地板的纤维。使用计算机程序模拟每种方案的总供暖和制冷能量需求，以确定哪种方案最节能。在仿真模型中，改变了建筑类型以及被动式太阳能和节能设计策略（PSEEDS），而其他参数（例如墙和屋顶厚度，窗户尺寸和总体布局）保持不变。研究表明，标准纤维房具有最高的冷却和加热能量要求（30,721 kWh / yr）。改进的反向砖饰面房屋的最低能源需求为9,628 kWh /年。在所有施工方案中，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，改进的砖饰面，反向砖饰面和双层砖房屋的供暖和制冷净能量需求最低。结果表明，建筑中包含的热质量（通过R值测量）和PSEEDS对能耗产生了重大影响。将这些设计特征整合到房屋的构造中，可以减少多达69％的加热和冷却能量需求。结果表明，建筑中包含的热质量（通过R值测量）和PSEEDS对能耗产生了重大影响。将这些设计特征整合到房屋的构造中，可以减少多达69％的加热和冷却能量需求。结果表明，建筑中包含的热质量（通过R值测量）和PSEEDS对能耗产生了重大影响。将这些设计特征整合到房屋的构造中，可以减少多达69％的加热和冷却能量需求。
