Building design needs to consider that the lifetime of its products will likely face relevant environmental and socio-economic changes, strong- ly related to the limits imposed by the geo-biosphere. Taking action to face such limits beyond trendy, debatable “green-washing” policies can be either a forward-looking choice or rather something imposed by ne- cessity. These have been the premises of the collaboration between hu- manitarian NGO Emergency Onlus and architecture firm TAMassociati in designing hospitals in the African regions of Sahara and Sahel: in fact, several African countries – long living in scarcity – represent an example and an opportunity to learn of some alternative to the mainstream devel- opment model. In this work, some vernacular building techniques are revisited towards a low-tech innovation for energy saving and renewables use that, in a next future, could turn out to be useful also for architecture in the Global North; they are here reviewed under a systemic point of view, and presented with the evaluation of their potential advantages in terms of long-term socio-environmental sustainability. The investigated low-tech innovations able to use local renewables yield net savings one order of magnitude higher than conventional solutions, while granting a strict energy demand such as that of a specialised North-like hospital in a hot dry area. Such results seem therefore as an encouraging example from which to learn also in other contexts with a milder climate, where possi- ble poorer energy drivers (e.g., the sun) would be clearly matched to less extreme conditions.
