The Integrated Roof Wind Energy System (IRWES, renamed – PowerNEST) is a new sustainable energy generation system for buildings. IBIS Power and Pontis Engineering have joined forces in getting this solution to a state where it is ready to enter the European market. The consortium has received a Horizon 2020 SME Phase II grant from the EC and has realized the first demonstration in the Netherlands. The initial stage of the overall European project consists of installing 25 units within 2 years, therefore gaining sufficient knowledge to develop a standardized mass production design and establish a distribution network. The EU independent review committee awarded a score of 14.35 out of 15.00 to the project with all aspects graded as ‘excellent’.
