We offer 4 assessment protocols :

Pair-wise comparison

Attribute assessment

Observers use their smartphone or their PCs, to select which of the two scenes (or videos) is the best answer to the question which is asked to them.

Observers use their smartphone or their PCs, to rate attributes of a scene which is presented to them.

Multichannel adjustment

Manual choice adjustment

Observers use their smartphone or PCs to adjust light, colours, materials, dimensions of objects in real time and select their preference. Technical or financial values like energy use or costs are calculated in realtime and displayed.
‍

Observers use their smartphone or PCs to navigate through a list of possible options and select their choice.
‍

We collect feedback from participants

Observers are invited, at the end of each session, to answer questions in an open or closed mode.

Closed question

Open question

Observers respond to questions using a scaleand selecting the value correponding to their choice.

Observers respond to questions through typing a text and bringing their comments.

HEALTHCARE

Light sources in urban environment drastically affectour perception of cities at night, and a compromise must be found to find thebest possible lighting solution, using as little electricity as possible. We have selected various issues below:

City beautification
Security for users
Energy performance

Reduction of spilled light
Useof low power luminous signage and beaconing

Daylight is welcomed in sport halls, but quantity anddirectionality have to be adjusted to the needs of players and to offer goodvisibility for the public. Position, size and shape of translucent materials matter.

Role of position of apertures
Role of size of aperture

In hospital, light quality challenges concern thepatients, the staff and the visitors with some time some contradictory expectations

DESIGN

HOTEL

MUSEUMS

Light simulations with precise optical algorithms canbe used to adjust components of luminaires or furniture. This concerns selection of materials, position of light sources as well as power, dimensions,and color of these light sources.

Light contributes to create a specific atmosphere, incombination to interior design. Furthermore, it can be dynamic and bring specific narratives.

Effects due to electric lighting are closely relatedto choices in interior furnishing. Daylight quality is mostly related to window design, dimensions, distribution as well as views out.

Change of aperture solutions with fixed total glazed area
Window solutions in attics
Glazed area versus floor area
Window solution in living room (house)
Window solution in apartment (depending on level aboveground)

Good lighting is required at office space, for thevisual task as well as the space in general. Compromises can be found todistribute light in ways, which meet requirements of occupants with the lowest possible electric power.

Strategies for task/ambient lighting
Meeting room options

Here architecture as well as the furnishing are designed to meet specificrequirements related, among other things to prayers, and staging. In historical churches.
