In particular, it will proceed to the installation of a system of this type in the laboratory of houses of Ikerlan-IK4 in the Technological Park of A comprehensive follow-up. With this it is intended to demonstrate that it is possible, economically, technically and environmentally, to adapt these facilities to the housings.
