本文总结了Ladacor有限公司开发的集装箱住宅单元的性能调查，并将其与按现有标准和规范建造的传统住宅进行了比较。结果表明，与按规范设计的相同住宅相比，案例住宅系统可以降低热负荷(采暖和制冷)约57%。实施额外的能效措施和太阳能设计战略，如增加南窗大小、适当的遮阳装置、热质量和更密闭的结构，可以提高性能。与代码方案相比，此增强方案可以将热负载降低72%，与原始案例研究系统相比，可以降低约35%的热负荷。在采用Ladacor屋顶设计的独户住宅的南面屋顶上集成光伏，假设使用节能家电、照明和生活热水，可以实现净零能源状态。最优方案可以达到净正能量状态，在朝南的屋顶表面集成光伏系统。这项调查的结果可以为低成本、自给自足的模块化住房的设计提供创新的设计理念和指导方针。
The paper summarizes an investigation of the performance of container based housing units developed by Ladacor Ltd, and compares this performance to traditional housing constructed according to existing standards and codes. The results indicate that the case study housing system can reduce thermal loads (heating and cooling) by about 57% as compared to the same house designed according to the code. Implementing additional efficiency measures and solar design strategies such as increased south window size, suitable shading devices, thermal mass, and more airtight construction, leads to improved performance. This enhanced scenario can reduce the thermal load by 72% as compared to the code scenario and by about 35% as compared to the original case study system. Achieving a net-zero energy status can be reached by integrating photovoltaics on the south roof of the single-family housing designed with Ladacor roof, assuming energy efficient appliances, lighting and domestic hot water. The optimal case can reach a net positive energy status, with a PV system integrated on the south facing roof surface. Results from this investigation can serve in developing innovative design concepts and guidelines for the design of low cost, self-sufficient modular housing.
