Level(s) is a common EU framework to measure the environmental performance of buildings with a life cycle approach. Beyond environmental aspects Level(s) also offers methods to take into account aspects such as occupants comfort and health, cost over the life cycle of the buildings and even risks associated to the changing climate.
Level(s) consists of 16 core indicators that can be aggregated within 6 macro-objectives:
The Level(s) common framework uses an organisation that is divided based on how advanced the reporting will be. The different levels follow the stages any building project requires
- Level 1: Conceptual design is the simplest, uses a qualitative assessment based on the expected systems, equipment and building properties.
- Level 2: Detailed design and construction performance of the building, this level carries out quantitative assessments of the designed conditions/specifications and controls the construction to ensure it follows the standardised units and methods (as designed).
- Level 3: As-built and in-use (including monitoring and surveying occupants) to ensure that the performance of the buildings is in line with the design and to adapt for building use changes and occupation modifications.
BIGG’s business case 2 is analysing Level(s)’ data requirements, searching and mapping all the sources of information that are needed to apply the Level(s) framework. The aim is to gauge the available information in open data combined with all the mandatory/essential documents for buildings such as the energy performance certificates (EPC).
