Environmental control in a windowless building measures indoor factors including temperature, human activity and human body temperature and simulates the outdoor environment. As well as air conditioning control, which may be general or local to a particular work area, the system may generate ambient sound (fig 4), simulate outdoor rainfall, level and colour of illumination and humidity (figs 5 to 7), project coloured lighting or images (figs 8 and 9) or generate aromas. Outdoor scenes may be generated using false windows (figs 10 to 12). The scenes may be coordinated along a succession of windows (figs 15-16) and may be animated. Alternatively, images of model objects may be projected (figs 18 to 20). The auxiliary wall housing the false window structures may contain ducting for air-conditioning. Human activity may be detected using cameras with picture analysis, skin reflectivity, radar, door operation, speech or an ID card which serves as a transmitter. The system is said to provide an optimum combination of the controlled factors to give the greatest degree of comfort. <IMAGE> |
