Illuminating Integrity in Lighting

About Us

Our Company

SunTracker provides professional lighting design software developed for the lighting industry beginning in 1996.

In 1994, Senior Scientist Ian Ashdown authored Radiosity: A Programmer’s Perspective (John Wiley & Sons). The software presented in this book has been under continual development since its publication, and is licensed to Lighting Analysts Inc. (Littleton, CO) for their AGi32, ElumTools, and Licaso products, and to Glamox AS (Molde, Norway) for their OptiWin 3D Pro architectural and marine lighting design software.

In 2012, SunTracker was granted its first patent for predictive daylight harvesting in commercial buildings. It currently has two granted patents and eight patent applications for greenhouse and commercial building control systems, circadian and spectral lighting, geometric simplification, real-time dynamic lighting simulation, and neural network controllers.

In 2015, SunTracker recognized the need for horticultural lighting design software for greenhouses, polytunnels, and vertical farms. In addition to developing its GreenhouseBuilder software, the company is working with academia on botanical research projects and with the American Society of Biological and Agricultural Engineers (ASABE), the Illuminating Engineering Society (IES), the Commission Internationale de l’Eclairage (CIE), and other organizations on the development of international standards for the lighting industry worldwide.

Today, SunTracker is at the forefront of software development for horticultural, architectural, and entertainment lighting design.

In Memory of Ian Ashdown

Beyond his renowned reputation as an engineer and scientist in the lighting field and beyond, Ian possessed a remarkable spirit of compassion. He selflessly assisted numerous individuals personally and professionally throughout their journeys.

Ian’s departure has left an immeasurable void; we deeply feel his absence. However, SunTracker Technologies remains unwavering in its dedication to preserving and advancing Ian’s exceptional legacy within the lighting community and beyond.
