Sustainable Construction


Promoting innovation, technology and standards for sustainable and healthy urban planning focuses ITG’s activity in the field of sustainable construction.

We are the official certifying body of BREEAM®️ in Spain, the first Market Partner in our country of the International WELL Building Institute (IWBI), founding members of the Format for Exchange of Building Database Standards (FIEBDC) and authors of different technical studies to promote sustainable practices in the sector.


ITG is one of the 5 entities recognised worldwide as the official certifying body for BREEAM®. A task that we carry out exclusively in Spain with this methodology that allows us to evaluate and certify the sustainability of buildings after a rigorous examination in up to ten environmental categories.

WELL Building Institute (IWBI)

Being the first and only WELL Market Partner in our country allows us to manage its training in Spain and Latin America, carry out its Performance Verification and organise the biggest official event of the certificate in Spain: the WELLFERENCE.

BDC Galicia y Euskadi

The Official Construction Price Database of Galicia was created in 1995 and is still in force today with the aim of improving transparency in the creation of budgets and promoting technological innovation and competitive improvement in the sector.

The technical rigour in its development by ITG led the Department of Housing, Public Works and Transport of the Basque Government to commission us in 2009 to develop its own Official Building and Urbanisation Price Database.
