Abstract
The social acceptance of introducing an improved and sustainable roofing material in multicultural communities in Mexico was addressed. A case history of a community “La Cañada” in Huixquilucan, State of Mexico (19°19′02.81″ N, 99°22′23.21″ W, 3025 m above mean sea level), a village very close to the eastern edge of Mexico City and representative of strong social and transcultural pressures similar to surrounding communities in Mexico City, is reported. The approach considered developing a double-layered roof to reduce the energy demand for space heating in this predominantly cold region, thus significantly contributing to indoor thermal comfort, reducing the need for cutting wood and helping to alleviate the accelerating impacts of deforestation in the area. Two parallel studies were used, whereby the then-current awareness levels of citizens and the factors impacting their commitment to energy sustainability were analysed using multicriteria social parameters, while the second study focused on the analysis of improved comfort when the proposed double roof was implemented, based on the feedback received from a pool of citizens who experienced living in the improved prototype dwellings. Results showed that while the level of awareness on energy efficiency was still low, the influence of media on their decisions and aspirations was strong and this could be constructively used to support the shift towards a more sustainable society and a “solar culture”. Moreover, the developed sustainable double-roof prototype has significantly improved indoor comfort and energy savings for heating, while demonstrating a fast and easy replicability potential in similar dwellings.
