DayMedia and MulCom are multimedia teaching packages targeted at architects and building engineers, as well as students. While DayMedia is concerned with daylighting in architecture, MulCom covers human comfort and the energy performance of buildings. Most of the content is related to thermal comfort, although acoustics and visual comfort are covered as well. The development of the packages has part-funded by the European Commission and coordinated by the Low Energy Architecture Research Unit (LEARN) of the University of North London.
