AQSI is based on the European Standard EN 16309,2014; ‘Sustainability of construction works – Assessment of social performance of buildings – Calculation methodology’. Although the title suggest it to be an calculation method, it is in the first place an very well-structured assessment method. Consequently the standard is rather conceptional.
This standard provides rules for the social performance of new and existing buildings. In other words: it provides a structure for the assessment of the People-facets from the TripleP of sustainability. Aspects related to People have are some extent all of a more qualitative and subjective nature. Nevertheless is the built environment meant to accommodate people’s needs for shelter, protection and comfort.
An assessment of any building is therefor incomplete without a thorough examination of the social impact. EN16309 provides the framework, AQSI makes it applicable.
The structure of EN16309 fits in the framework of EN15643 ‘Sustainability of construction works – Sustainability assessment of buildings. General framework’. That framework is displayed in the figure. EN16309 also is related to EN 15643-3 ‘Sustainability of construction works. Assessment of buildings. Framework for the assessment of social performance’. An assessment according to EN16309 therefor is a fulfilment of the red area’s in the diagram. The conceptional nature of this assessment method is intensified due to the open composition, without limits, schedules or any other quantitative aspects.
The method described in N16309 is fit to the assessment of a building, its function and the surroundings. It assesses not only the building and its construction, but also aspects of operating, maintenance, replacement and refurbishment. Both architectonic design and materialisation are key issues. ASQI provides an insight in qualitative aspects of the building for its user, that otherwise would be neglected. It reveals hidden aspects of the implemented building materials. The social impact of the building becomes visible and tangible. When assessing the sustainability of a building design, AQSI is the tool that puts social impact in the spotlight.
Link with sustainability certification methods
AQSI is an addition to existing certification methods on sustainability of buildings, such as BREEAM, LEED and de Dutch GPR-Gebouw. AQSI is based on the use of the building. AQSI reveals hidden qualities of building parts and materials, that are an implicit part of the building concept, the energy solution or the chosen materials. Furthermore a assessement of future refurbishment-possibilities is interlaced, by adding a scenario as an obligatory aspect.
