AGi32 Lighting Software: A Powerful Tool for Lighting Design and Analysis
AGi32 is a software tool used to predict the lighting performance of electric luminaires and/or daylight in a simulated interior or exterior environment[^3^]. The environments that may be considered in AGi32 can range from a simple interior space to an exterior site lighting or a complex auditorium.
AGi32 can provide numeric and rendered solutions for almost any lighting application, interior or exterior, including roadway, sports and daylighting[^1^]. AGi32 is first and foremost, a calculation tool for accurate photometric predictions: A technical tool that can compute illuminance, luminance, exitance, daylight factor, glare rating and other metrics in any situation, assist in luminaire placement and aiming, and validate adherence to any number of lighting criteria[^1^]. However, there is so much more that can be done to enhance the understanding of photometric results. Visualization is extremely important to comprehend changes in luminance for different materials and surface properties and predict the effect of various luminaire designs in real-world, light and surface interaction. With the ability to see results clearly for an entire project, AGi32 becomes a mock-up substitute that can save time and money by creating a virtual model of a proposed design. It can reveal characteristics and effects that would be hard to detect in anything short of the completed installation[^1^].
AGi32 allows you to select from two calculation techniques when simulating a lighting application: Direct Calculation Method and Full Radiosity Method. The use of either method has its merits and is an important choice you will need to make for any application. It is easy to move from one to the other and simply repeat the calculation[^2^]. Direct Calculation Method considers only light directly from luminaires to calculation points and is capable of point-by-point results only, it cannot be rendered. This method lends itself particularly well to exterior lighting projects such as site lighting, roadway and sports applications. It may also be utilized for fast direct light calculations in interior facilities. The obstructive nature of surfaces is considered[^2^]. Full Radiosity Method enables all features for the accurate computation of interreflected light. Full Radiosity Method is required for interior lighting applications where interreflected light and indirect lighting are important or when rendering is desired. Due to the rigorous nature of interreflected lighting calculations, Full Radiosity Method projects require a little additional run time over Direct Method projects of the same scale. Switching between Direct and Full Radiosity Method is as simple as a mouse click and can be performed anytime[^2^].
AGi32 has the ability to automatically place specific grids of calculation points on any surface as well as on designated workplanes. This command is very powerful and convenient and saves the time it would normally take to place a conventional grid of points on the surface and eliminate unwanted points. Curved and sloping surfaces are easily accommodated. In fact, using the Automatic Placement command is the method of choice when placing calculation points on irregular surfaces[^2^]. AGi32 can also utilize a variety of techniques, such as polygons, grids, lines and single point specification to place calculation points anywhere in 3-dimensional space. These capabilities allow AGi32 to predict or quantify the distribution of artificial light in any environment. An unlimited number of unique calculation planes can be specified. Calculation points can be aimed in any direction and elevations can be considered to track irregular topography[^2^].
AGi32 is a simulation tool used for designing lighting projects and calculating the amount of light that will be delivered based on user-set parameters. The resulting calculations are commonly referred to as lighting layouts or point-by-points[^4^]. AGi32 is a computational program that performs numerical point-by-point calculations of incident direct or reflected light on any real surface or imaginary plane[^5^]. AGi32 is a software product developed by Lighting Analysts Inc., a company that has been developing software tools for lighting professionals since 1984[^1^].
