Programme summary
The "see-it" project is researching technologies in the field of building construction and building automation for quality and performance improvements in the workplace. The aim is to individualise the control of sun protection to the people to be protected from glare and overheating and those hoping to see through.
Initial situation/motivation
We can already see Matrix headlights on the road today; they are state of the art in the automotive industry. The digital matrix sun visor "Virtual Visor", presented at the Consumer Electronics Show (CES) in 2020, may also soon protect us from glare in our cars.
So while light can be finely adjusted in the automotive sector, the sun's radiation through our large building windows can only be influenced in a relatively undifferentiated way with certain types of sun protection. At the same time, however, it is precisely this radiation through the transparent building envelope that determines the quality of the workplace.
Adequate daylighting and artificial lighting lead to significantly better sleep, fewer sick days and less painkillers taken. Good workplace lighting has a demonstrable effect on posture and therefore musculoskeletal comfort, and contact with the outside world also has a positive impact on health.
The see-it project is researching the above-mentioned technologies in the field of building construction and building automation for quality and performance improvements in the workplace.
Contents and objectives
The project title see-it stands on the one hand for the seeing sensor system that detects people and on the other hand for the "seeing" users, who are better able to perform work tasks thanks to ideal daylight conditions.
As a research project, see-it describes a model-predictive control ecosystem. It weighs up different façade settings transdisciplinary according to a target function. The target function includes, for example, best comfort, minimum CO2 emissions, maximum daylight utilisation, minimum energy demand, minimum overheating (in the room, building and neighbourhood) and maximum circadian stimulus with variable weighting.
Methodological approach
Research, functional samples, demonstration and evaluation in living labs as proof of concept.
Expected results
The consortium is aiming for a positive result from the proof of concept. The spatial detection of people and furniture is carried out with adequate accuracy. The conflicting interests between heat protection, glare and visibility to the outside are solved in the best possible way by a practicable influenceability of the solar radiation.
