註釋Although cost is a major determining factor in the selection of northern buildings, and has been a prime concern in this discussion, it is also essential that each building system used in the north be technically adequate for cold weather conditions. The system must provide, in addition to strength and rigidity, resistance to heat flow, water vapour flow, liquid water movement, and fire. The prefabricated panels can individually meet these requirements, but the final performance of the structure is dependent on satisfactory joint details, and these have often proved difficult. In recognition of the importance of total prefabrication in meeting the problem of northern building, the Division of Building Research has recently completed detailed studies of the currently available systems, the results of which will shortly be published in a technical paper. It is evident that the light-weight systems can meet these performance requirements. In addition, their modular panel design makes them adaptable to any type of building with flexibility in layout, window placement and appearance, and the low final cost of the stressed skin units in particular makes these, and further evolving systems, attractive in the establishment of communities in the north of Canada.
