AQSI supports a construction professional in creating a building assessment according to NEN-EN 16309. By that one can develop an insight and comprehension of the social sustainability aspects of a building. AQSI is not a calculation tool and does not produce a score, report number, or number of “stars”.

An assessment of the social sustainability aspects with AQSI is an assessment of a building in its location. Both aspects are dealt with, but the emphasis is on the use of the building and on the influence of things like maintenance and renovations on the users. An assessment in AQSI consists of a number of logical steps.

Characteristic space

A building-assessment with AQSI starts with a brief description of the building and the capture of basic data. Then also – and that is specific to AQSI- a number of characteristic areas is requested. That are areas that are characteristic for the building and its use. In regard to AQSI, it will always concern spaces in which people are present for an extended period of time. In an office that are for instance a common workplace, cubicle a meeting room and an instruction facility. In a dwelling it most likely will be the living, sleeping room and perhaps the outdoor area. The choice of the number of characteristic rooms is free to be determined by the assessor. Each building requires at least one characteristic room.


An assessment with AQSI is based on a scenario for the future of the building. The review based on a future scenario is a characteristic part of NEN-EN16309. A number of example scenarios is included in AQSI, in addition one can define a project-specific scenario. The chosen scenario affects the aspects that later will occur during the assessment.


Next the materialization of the building and the characteristic areas are registered by a choice of pull-down menus. AQSI has a database with a large number of specific data of building parts and construction products. It is always possible to choose for more generic materials or constructions. The more specific the choice can be, the more differentiated the outcome of the assessment will be. The database is composed of data from public sources and with detailed information of affiliated companies.


AQSI generates a number of aspects of social quality that can be assessed. These are all aspects from NEN-EN 16309 relevant to the building, with its characteristic spaces at the chosen scenario.

The evaluator then covers the six AQSI-topics in any order. He also can enable or disable items manually. AQSI generates at each line a number of quality aspects associated with the chosen materialization. The assessor writes a summary per topic, based on his own knowledge and perception of the project.


AQSI generates a report. The assessor completes the report with his final conclusion based on the assessment.
