Green and transportable modular building: A prefabricated prototype of resilient and efficient house

Abstract

Remote working proved to be an advantage in terms energy-saving as well as, for many, in terms of quality of life, while it was a necessity during the pandemic crisis of 2020/2021. This new habit is now promoted by many big enterprises due to associated cost savings. Some experiences of remote working in different locations have started to be supported by incentives in small municipalities to repopulate remote locations in Italy and people are now more inclined to move not just for vacation. These conditions could lead to a sort of “climatic nomadism” achievable, among other, through transportable homes. The net-zero energy Green and Transportable Modular Building (GTMB) project is able to cut its environmental impact. It can assume different configurations according to the user's needs. The house is based on a timber construction system, easily adjustable and adaptable according to a modular framework. The energy performance has been simulated by means of BIM/BEM methodologies. The building has been tested in two different climates and configurations according to variable social interaction. The energy balance of the house in the life cycle showed the achievement of a carbon zero balance mainly due to timber technology, a heat pump, and PV integration.
