The application of the scientific method in the design of architectural spaces is known as Evidence-Based Design (EBD), a translation to the world of architecture of the concept Evidence-Based Medicine.
The EBD raises the investigation by multidisciplinary teams (architects, engineers, psychologists, doctors …) to find scientific evidence linking design parameters (configuration of space, materials, lighting, acoustics …) with user outcomes.
Literature reviews reveal an exponential progression of studies, reaching 1,200 in 2008, mainly in the field of health architecture due to the special needs of its users.
Thus, it has gradually become clear that certain design criteria contribute in reducing the perception of pain, improving rest, reducing stress, spatial orientation, privacy and security, social cohesion or overall wellbeing.
Kansei Engineering was developed in the 70s by Professor Mitsuo Nagamachi at the Kure Institute of Technology (Hiroshima, Japan) for application in the field of User-Centered Design.
Kansei is able to find the relationship between user´s emotional perception of a product, design parameters and the final assessment of the product.
The principal advantage over other techniques of analysis of preferences (QFD, Conjoint Analysis, etc.) is establishing a framework for working with symbolic attributes and user perceptions, expressed in their own language.
Kansei Engineering has been applied mainly in product design. It has been used in the automotive industry (Mazda, Nissan, Mitsubishi), furniture, mobile phones or shoes.
The Research Group Neuroarquitectura LENI has experience in designing Evidence-Based Design studies for health spaces and is a pioneer in the application of Kansei methodology in the field of evaluation of architectural and urban environments or real estate developments.
