Patio 2.12 is a prototype of an energy-efficient, prefabricated home inspired by the tradition of the Andalusian Mediterranean style house. It boasts the latest renewable energy and energy efficiency technologies. The modular, sustainable and self-powered prototype home “Patio 2.12” has been developed by Team Andalusia, made up of four Andalusian universities (universities of Seville, Malaga, Granada and Jaén) .
Patio 2.12 leverages spatial and bioclimatic conditions of the Andalusian courtyard house for greater energy efficiency. In the search for a dialogue, integration and negotiation between architecture, bioclimatic and energy efficiency, the project has maintained a constant tension in the design process. The prototype combines the traditional features of an Andalusian Mediterranean-style house with the latest solar photovoltaic, passive heating and cooling, energy efficiency, home automation and prefabrication technologies. The dwelling comprises four prefabricated modules, each of a size that "permits a combination of uses" (kitchen-dining room, lounge-office, bedroom-bathroom, powerhouse-utility room-gymnasium), linked by a central space referred to as the "technological patio", which recreates the climatic conditions of traditional Andalusian patios using automated pergolas and adjustable glass enclosures. Team Andalusia has also introduced various innovative ideas in the interior spaces: flowing and versatile spaces, prefabricated compact bathroom suites, etc.
The team's choice of cutting-edge technologies does not reflect a decision to reject "traditional" materials such as tiling, which has been integrated into the enclosures as thin sheets or timber (from sustainable forests), which have been used to build the prototype's structure and helps to reduce its ecological footprint.
In terms of solar energy, the prototype's photovoltaic panels generate three times as much electricity as the home consumes. Some of these panels are mixed, also housing solar thermal panels for hot water provision. An automated system regulates the home's demand curve with the supply curve, determining the best time to use the electric appliances. A smart meter is a crucial component in this entire process.
