Abstract: Sustainable building lighting and energy modelling and control, and the associated computer graphics, including real-time dynamic lighting simulation, are concerned with: an optimized method for radiance modelling, including its application to predictive daylight harvesting; and the real-time simulation of physically-based electric lighting and daylighting for architectural, horticultural, and theatrical lighting systems visualization. In order to display and analyze in real time a photometrically accurate representation of an environment, thousands of lighting channels may have their intensity settings continually varied such that a user may interactively view the three-dimensional environment without the need for ongoing global illumination calculations. This can be accomplished utilizing texture maps as a multiplicity of canonical radiosity solutions, each representing a lighting channel for dynamic lighting simulation, and storing the solutions in the texture memory of a graphics processing unit.

Abstract: In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment.

Abstract: Laser light is coupled to optical fibers arranged in a sheet, which may be in the form of netting, mesh or fabric. Scattering centers or bends in the optical fibers allow the coupled light to escape from the sides of the fibers. Depending on the selection of wavelengths for the lasers, the resulting luminous sheet may be used for illumination of crops grown in vertical farms. The laser wavelengths excite plant photopigments for predetermined physiological responses, and the light source intensities may be temporally modulated to maximize photosynthesis and control photomorphogenesis responses. Each laser may be independently controlled, and at least one laser may emit ultraviolet-C radiation. The luminous sheet may be used for purification of air flowing through an air duct.

Abstract: A biological lighting system to provide temporally- and spatially-modulated photon flux output and spectral power distributions to plants on a circadian and circannual basis, or circadian and life cycle basis, to maximize effective and efficient growth in a horticultural setting. The photon flux or irradiance output and the spectral power distribution are modulated to match circadian and circannual rhythms, with individual or multiple luminaires controlled through one or more controllers. Different lighting spectra can be employed depending on the direction of illumination. The photon flux or irradiance output and the spectral power distribution may be set as best suited for any particular plant species, and the system is also useful for raising animals.

Abstract: Laser light emanates from optical components that are mounted on a substrate, each optical component being coupled to an optical fiber that delivers laser radiation combined from multiple lasers. A linear or elliptical holographic diffuser is located to diffuse the light emanating from the optical components. The laser wavelengths excite plant photopigments for predetermined physiological responses, and the light source intensities may be temporally modulated to maximize photosynthesis and control photomorphogenesis responses. Each laser is independently controlled. At least one laser emits ultraviolet-C radiation.

Abstract: Electric light sources typically exhibit temporal variations in luminous flux output, commonly referred to as “flicker.” Flicker, or temporal modulation, is known to influence the growth, health and behavior patterns of humans, and is also linked to growth, health and behavior patterns throughout the growth cycle of plants and animals. Control of peak radiant flux emitted by a light source to temporally modulate a light source will allow for the control of plants and animals for sustainable farming including but not limited to horticultural, agricultural, or aquacultural endeavors. The light source allows the transmission of daylight, which is combined with the flicker.
