The design of the Oryza house is the result of the sun trajectory, the winds characteristics, the land shape and the location of olive trees.

​

The construction system creates an envelope with a high thermal resistance. The insulation is 25cm in the walls, 24cm in the roof and 12cm on the slab. The heating demand is covered by a biomass stove.

​

Appliances, lighting and water heating are powered by an isolated photovoltaic generation system of 3,10Kwp. The electrical energy is stored in batteries.

​

The house also has a rainwater storage system. We use this water to flush the toilets, to clean clothes and to irrigate the garden.

​

The Oryza House is considered a nearly Zero Energy Building due to its low heating demand and the self-generation of electricity.
