The "Oasis House" (Casa Oasis) - Eco Friendly House

One of our constructions, the "Oasis House" in Estoi was assessed by the pilot version of the "LíderA" Sustainability Evaluation System in 2006, contributing to our mutual development. In 2007 it was the first villa in Portugal certified with the A level of high environmental performance standards, and in 2015, after several updates, it was certified LíderA++, being the first building in Portugal to have achieved the top rating A++ with the highest score so far. This means to be approximately 10 times more sustainable / efficient than a usual building.
