post occupancy evaluation



The integration of knowledge of environmental psychology offers a new method of designing spaces by enabling designers to base design decisions on credible scientific research and to make righteous and legitimate presumptions about the impact of design elements on users. As a consequence clients and stakeholders can make better-informed financial decisions that can be an adequate basis for a business case.

The new way of designing not only involves the use of scientific literature, but also requires a PRE DESIGN ANALYSIS (PDA), a research study prior to the design process, that produces important input for the design team by showing opportunities, concerns and pitfalls of the current situation – making a more tailor-made design possible. Ideally this new design method requires the long-term commitment of an interdisciplinary team that stays involved during the whole design-process. To create empowerment, ownership and confidence in a new environment, D/Science ultimately also strongly encourages the participation of users in the design process.


Feeling an economic and social responsibility that we cannot longer solely rely on assumptions that a new design will have the desirable effects, D/Science applies EVIDENCE-BASED DESIGN (EBD) to systematically evaluate the impact of environments on people. EBD implies an essential change in the way organizations think about, deliver and manage buildings. It reflects the ability of an organization to transform and innovate, a willingness to measure organizational outcomes and confront the results of an evaluation.

Effect-research, also known as a POST OCCUPANCY EVALUATION (POE), consists of a before-after comparison. A POE therefore represents a vital opportunity in real estate to relate physical design features to organizational outcomes and employee perceptions regarding health, well-being and productivity. It offers insight into the performance of a building and to what extent the environment is successful in stimulating productivity, supporting behavioural lifestyle changes or facilitating the achievement of any other key performance indicator.
