Research and innovation help improve our environmental performance, energy efficiency, the fight against climate change and water management, amongst others. In order to move forward in this field, we collaborate with various universities and cutting-edge research centers.


(Retrofitting Solutions and Services for the enhancement of Energy Efficiency in Public Edification),

an RDI initiative included in the Seventh Framework Programme of the European Union, for the development of energy efficiency strategies and solutions applicable at the refurbishment and renovation stages of public buildings, to include smart materials, nanotechnology, renewable energies or energy storage systems.


(Built to Specifications: Self-Inspection, 3D Modelling, Management and Quality-Check Tools for the 21st Century Construction Worksite), the aim of which is to establish improvements in constructive process quality checks, in order to reduce the gap in a building and/or structure’s energy consumption, once it is constructed or refurbished.


(Affordable Zero Energy Buildings),

contemplates the study and selection of technologies applicable to various climate zones in Europe, by evaluating different case studies, in real conditions, in countries belonging to the consortium: Spain, France, Germany, Italy, Bulgaria and Holland.

About 60 projects with sustainable certification

In the field of singular buildings, we apply sustainability criteria that respond to the LEED®, BREEAM®, Passivhaus, CES and WELL methodologies. Also, through the search for efficiency through the application of techniques and processes based on innovation, usability of infrastructures and on contributing to the well-being of its users.
