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.
