| The first privately promoted
building in the EXPO’98 intervention area to apply passive and active solar
technology as the main energy source, displaying the viability of this system in
high-density residential buildings with southern European climatic conditions. With a generous window area, all the living units
benefit from high solar gains. The building does not have artificial climate control and
neither will it be connected to the heating fluid distribution network. Supplementary
energy requirements for heating, at only 20% of the regulation values, are partly
satisfied by a system of heated water connected to the solar panels of the outside cover.
Good conditions of natural lighting, acoustic insulation and pollution protection of the
inner atmosphere complete the buildings profile.
