  • Buildings are responsible for, approximately, half of the energy consumption of the planet. Designing buildings with energy saving criteria is fundamental in reducing the consumption, but it is not enough. It is becoming more and more necessary to integrate efficient production technologies and energy management. Building codes are introducing the requirement to reduce both the energy demand and consumption in buildings, in order to reach a nearly-zero energy consumption in a few years time. In this context, the concept of Regenerative Building appears; it is the one able to give back to nature the energy consumed during its construction process. To meet the parameters of a regenerative building, not only is it necessary to design with energy-efficient parameters and to choose suitable devices, but it also requires new materials and constructive solutions that make the building an energy producer, either for its own use, or to pump it in the existing city network. Given the passive actions, which favor thermal insulation in buildings, active elements able to produce and manage energy in their immediate surrounding have been developed. One of these systems is the active water-flow windows. The advantage of water, compared to other stone materials, is its great heat capacity; it has a larger storage capacity per volume unit than the materials mentioned. Furthermore, water has the ability of transporting energy. It is transparent to visible solar radiation, and resistant to infrared radiation, so the use of this glazing allows the light to trespass, and blocks the heat. The Technical Building Code, opposed to traditional prescriptive codes, is based on allowances and implies more openness to innovation. This option is justified, since the building knowledge and technology are in constant progress, in such way that regulation promotes research and does not hinder technological progress. The active water-flow window panels are being introduced in the market. This article shows real data obtained by means of monitoring a building that integrates this technology in its envelope.
