Predicting spherical irradiance for volume disinfection
Given the complexity of architectural spaces and the need to calculate spherical irradiances, it is difficult to determine how much ultraviolet radiation is necessary to adequately kill airborne pathogens. An interior environment with luminaires is modeled. Spherical irradiance meters are positioned in the model and the direct and indirect spherical irradiance is calculated for each sensor. From this, an irradiance field is interpolated for a volume of interest, and using known fluence response values for killing pathogens, a reduction in the pathogens is predicted. Based on the predicted reduction, spaces are built accordingly, and ultraviolet luminaires are installed and controlled.

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.
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.

Melanopic dose rate and dose are calculated in a virtual environment. A computer generated model of an actual or planned building is used as the virtual environment. Indirect and direct spherical irradiances are calculated using convex polyhedra throughout the virtual environment, and each is multiplied by a melanopic conversion factor. The two are added, then adjusted for a human's angular responsivity and age. Building design features or lighting devices may be adjusted to provide a required melanopic dose rate. A camera is used to capture a panoramic image, which is calibrated to tristimulus values, and used with the spectral power distribution of the light sources to derive the melanopic dose rate.

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.

System and method for neural network radiosity calculations
A system and method for a neural network that is trained to recognize patterns in the exitance convergence behaviour of a radiosity equation being solved for a set of finite element environments, and subsequently employed to monitor and predict the exitance convergence behaviour of novel finite element environments. The neural network is trained with feature vectors representing partial snapshots of exitance vectors at various iterations in a radiosity calculation. The feature vectors are related to numbers of iterations that can be skipped by making approximate calculations instead of performing the iterations. In use, when a radiosity equation is being solved, the neural network identifies feature vectors generated during the calculations that signify that a certain number of iterations can be skipped by making an approximate calculation.

A means to automate, using fuzzy logic, the classification of spectral power distributions of optical radiation for lighting systems, and more particularly horticultural lighting systems, is presented. After inputting the spectral power distribution of optical radiation from one or more light sources, radial basis function weights for the spectral power distribution are determined and fuzzified preparatory to fuzzy logic classification. Fuzzy if-then rules are then applied, and an aggregate of the rule votes from the fuzzy if-then rules applied is used to classify the spectral power distribution. The system utilizes a spectral sensor, a fuzzifier module, a fuzzy rule database, fuzzy rule engine, an output fuzzifier module, and a means of displaying the spectral power distribution classification.

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.

A dense array of sensors positioned in a virtual environment is reduced to a sparse array of sensors in a physical environment, which provides sufficient information to a controller that responds to environmental conditions and parameters in the physical environment in substantially the same manner as it would to the same environmental conditions and parameters in the equivalent virtual environment. Data from a sparse array of virtual sensors is correlated with data from a dense array of virtual sensors and is used for generating control signals for hardware devices that influence a real or virtual interior environment. The correlated data and the control signals are used to train an artificial intelligence based controller that then controls the values of the parameters of the interior environment. A model of the interior environment is created using basic parameters in a computer-aided design application.

Based on the target distribution of the artificially modulated environmental parameters, the method includes setting output parameters for control devices to collectively control the actual distribution of the set of environmental parameters.

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.

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, including diffusion characteristics of the materials between environments.
