Sustainability assessment of a Flemish office building with Level(s): a Level 1 assessment

Journal Contribution - Journal Article Conference Contribution

Recently, Level(s) has been developed by the European Commission as a commonEU framework to assess sustainability of buildings with the intention to provide a consistent andcomparable framework across national boundaries. It aims at providing a general language forsustainability for buildings and to promote life cycle thinking. This paper describes theapplication and results of a Level 1 assessment for the design stage of a Flemish office building.Level 1 is a common performance assessment which aims to be used amongst others by buildingprofessionals. Common standards and simplified methods are used for the indicators. The paperfocusses on the experiences of testing the method by evaluating the user-friendliness of theassessment method for architects considering the information and calculations needed. Theadded value of applying the methodology in the design stage is furthermore discussed. Based onthe test phase, further improvement is recommended by aligning current national tools for datagathering and by providing default values. A Level 1 assessment allows to gain insights invarious performances of a building but does not aim to evaluate the “sustainability” level. Alevel 2 assessment is probably more useful for practitioners to make well-founded choicesbetween different design options.
