    Temporary dwelling for the high altitude andean region of Puno, Peru
    (University of A Coruña and Asoc. PLEA2020 Planning Post Carbon Cities, 2020) Jiménez, Cecilia; Montoya, Teresa; Loayza, Silvana
    Peru is a seismic country. The impact of these events is significant in poor and rural regions, where people are most vulnerable and government emergency response takes time and reconstruction of housing and community buildings can take years. In addition to earthquakes, the high altitude areas of Puno, above 4000 meters above sea level, is inhabited by small rural communities with very poor living conditions, extreme cold weather, and few resources. There is a long tradition among the native families around the Titicaca Lake of working with “totora” to make mats and baskets; they even build islands on the lake where they live in their “totora” huts. The objective of this research is to design and evaluate the prototype of an appropriate temporary housing using “totora” as insulation material when disasters occur in these poor and harsh environments of southern Peru. Working with the Lake community of Chimu, a prototype of a temporary house made of “totora” panels was built in Puno. It was inhabited and monitored for three months to evaluate its thermal, structural and functional performance. Results showed that the prototype made of “totora” panels performed better than other temporary dwellings and typical houses of Andean high-altitude rural areas.

    Improving thermal performance of traditional cabins in the high-altitude peruvian andean region
    (Network for Comfort and Energy Use in Buildings, 2017) Jimenez, Cecilia; Wieser, Martín; Biondi, Susana
    Communities in the high-altitude region of the Peruvian Southern Andean Mountains are located over 4200 meters above sea level. Communities organize in isolated cabins dispersed in an extensive area surrounding the community center. The harsh natural environment and poor living conditions affect people’s health and increase child mortality, especially in winter. Daytime solar radiation is of high intensity. At night exterior temperatures are -10°C, while indoor temperatures of cabins barely reach 0°C. This research sought to improve the thermal performance of these cabins with passive design strategies and local resources. The methodology included: a) collection of weather data versus indoor thermal performance, availability of local resources and understanding domestic organization patterns; b) definition of comfort temperature range and analysis of local materials; c) technology transfer by involving the population in the construction of a prototype. Simple passive strategies of air tightness and solar gain with local available materials (adobe for walls, totora reed (Schoenoplectus tatora) and sheep wool for insulation, and stone and wood to waterproof the floor) improved night thermal performance in these isolated areas. Although local people are starting to implement these techniques in their own cabins, this is just the starting point towards appropriate thermal comfort.
