The purpose of this research was to propose and build a sustainable, low-impact, optimized, modular lodge, to facilitate scientific studies in the Antarctic. Within this unique climate, this paper presents new environmental and sustainable approach for the extreme cold. The Polar Lodge was designed and built with a primary concern of proposing a zero carbon emission module. Other major concerns included that the proposal should be: modular; easy to transport and fast to assemble by a small team of non-experts (size and weight of parts was critical); resistant to wind; have minimum impact on the ecosystem; dry; warm; safe; physically and psychologically comfortable. The solution presented was inspired and adapted by the traditional Yurt. Scientific data was collected and analysed regarding the lodge s performance in the extreme environmental conditions with the use of data loggers. The environmental comfort and thermal performance of the Antarctic yurt was tested for two consecutive days by the team of researchers in an isolated area on Collins Bay. Data was collected and the experience registered, substantiating environmental comfort on physiological, psychological grounds. Finally, this paper also intends to contribute to the scientific efforts of low energy building, within the concerns of climate change and sustainability. © Copyright 2017 NCEUB.
