Analysis of Sustainable Energy Systems in Ecovillages: A Review of Progress in

This paper explores sustainable energy systems in ecovillages based on the concept of the Zero Energy Building. The cases discussed in this paper include BedZED in the United Kingdom and Masdar City in the Middle East. These two communities contain features characterized by the sus-tainable principles of the ecovillage concept by using renewable energy and reclaimed materials to reach a low/zero energy system in buildings. The creation of more ecovillages and the growth of current ecovillages play an important role in positively solving environmental and social prob-lems. The low energy buildings in the ecovillages also act as a model for communities wishing to implement sustainable development
