Looking forward to collaborating with all the partners of the EuropeanGreenBauhaus proposal.


LEITAT has been pleased to contribute to the EuropeanGreenBauhaus consortium, responding to the Green Deal call, that would bring together a set of innovative energy-saving and energy-producing methods and technologies guaranteeing a positive environmental impact through the entire lifecycle of a building, such as 1) energy-saving design methodologies and tools, 2) energy-efficient construction materials & techniques, 3) integrated renewable energy generation & storage solutions and 4) smart energy management solutions.

As such LEITAT will integrate an electrowetland, a nature-based technology that are being tested in Valladolid to treat in-situ the urban wastewater and monitor environmental parameters within the UrbanGreenUP project. Resulting from the synergy between constructed wetlands and microbial fuel cells, electrowetlands are able to treat wastewater from urban sources and to generate electricity simultaneously from the degradation of the organic matter present in wastewater.  The low power density of the generated electricity allows to power different environmental and water quality sensors used to monitor and control the wastewater treatment plant. The electrowetland technology, easily integrated in neighborhoods requiring delocalized wastewater treatment will be deployed at Vilameniscle (Alt Empordà, Catalonia) one of the three lighthouse demonstrations that will cover together a total of 4,100 m2 of sustainable construction and 2,787 m2 of sustainable renovation, enabling a total annual embodied & consumption reduction of 105.5 tCO2/year

Additionally, PlasmoChromic smart windows, developed and patented by LEITAT will be up-scaled and installed on one of the building façades of the Da Vinci Lab lighthouse and will be driven by an innovative occupant cantered control algorithms capable of quantify and minimizing thermal actions to reduce energy consumption and maximize both thermal and visual comfort. PlasmoChromic smart windows, currently developed in the framework of the INFINITE project, are able of selectively control the incoming solar radiation in the near-infrared range in response to variable external and internal operative conditions, allowing building occupants to dynamically filter out the amount of thermal radiation passing through the window by means of blocking the solar heat gain during hot summer days and to allow radiation heating in winter conditions beyond the  continuous regulation the level of visible transmittance of “traditional” electrochromic windows.
