Subsequently to the verification of certain limits in the general practice of temporary structures for events, the research project "On STAGE" (sustainable temporary arenas for gigs and events) entails developing an integrated alternative regarding improved characteristics of sustainability. The project aims particularly at obtaining the following matters: architectural expression, flexibility of use, response to acoustic requirements, optimization of the thermal comfort by bioclimatic principles, ideal utilization of renewable resources and efficient utilization of the infrastructure. One of the originalities of the project is to deal with the challenges of permanent architecture in the area of a temporary and transportable construction. From that results a confrontation between the objectives of sustainability and a short time of amortization leading to experimentation with constructive innovative solutions, potentially applicable to permanent constructions.
