Increasing problems regarding pollution and climate change have long been demonstrated
by scientific evidence. An important portion of carbon emissions are produced by the building sector.
These emissions are directly related not only to the building’s energy consumption, but also other
building attributes a ecting the construction and operation of existing buildings: materials selection,
waste management, transportation, water consumption, and others. To help reduce these emissions,
several green building rating system (GBRSs) have appeared during the last years. This has made
it di cult for stakeholders to identify which GBRSs could be more suitable to a specific project.
The heterogeneity of the GRBS scenario requires the creation of a transparent and robust indicator
framework that can be used in any country within the European Union (EU), which is a common
EU framework of core sustainability indicators for o ce and residential buildings Level(s) with
the goal to provide a solid structure for building sustainability certification across all countries
of the EU. This paper provides a comprehensive review of the most common GBRSs within the
EU: Building Research Establishment Assessment Method (BREEAM), Deutsche Gesellschaft für
Nachhaltiges Bauen (DGNB), Haute Qualité Environnementale (HQE), and Leadership in Energy
& Environmental Design (LEED), and a bottom up comparison of the influence in the final score
produced by the indicators stated by Level(s). The indicators studied show a di erent influence of
Level(s) indicators on every GBRS, where LEED and BREEAM were most a ected while HQE and
DGNB were less so. This paper demonstrates the heterogeneity of current GRBSs in the EU scenario
and the di erence between sustainability assessments, where DGNB seems to be more aligned to
the current EU framework. Finally, the paper concludes with the need to work to achieve alignment
between the GBRS and Level(s).
