Light is indispensable to human beings. Human beings get a huge amount of environmental information of the outer world through vision. Koga Laboratory is working on design, evaluation and control of indoor and outdoor luminous environments from aspects of environmental physics and human psychology and physiology. For designing and controlling comfort and healthy architectural spaces, we were engaged in long-term measurement of daylight and solar radiation, development of various daylight models, and investigation on different spectral power distributions of light sources and visual responses relevant to sleep and wakefulness.
We have participated in research activities on lighting in buildings for the Solar Heating and Cooling (SHC) Programme of the International Energy Agency (IEA) since 2001. A new project “Low Carbon, High Comfort Integrated Lighting” was launched in 2022. We are working on digitized lighting solutions, parametric and automated design options, and utilization of advanced VR technologies in collaboration mainly with European researchers.
For design and evaluation of architectural spaces utilizing the virtual environment, we are now focusing on development of design methods for the building envelope and windows based on visual information of 3D urban models.
