Gradis has developed a complete solution for outdoor lighting system optimisation and control, called PhoCa. Using this platform we are able to provide an energy cost reduction of more than 20 per cent. The exact reduction factor depends on a set of parameters and environmental factors. The system can also focus on the dynamic aspect of the infrastructure and provides a set of profiles, which can be dynamically applied to improve performance.

The need

The world market for smart-lighting systems has been
growing rapidly – 18-20% annual growth rate is expected until 2020.
Operators (e.g. administrations, cities) need to create optimal and costeffective
solutions for new and existing installations. Solutions need to be
created for more dynamic control, to decrease maintenance cost and to
obtain a better ROI of investment.

The solution

The primary field of service is design and optimisation, using multiple factors such as lamp type, lamp location, installation parameters, maintenance costs, etc. to provide an optimal design variant. Clients can choose their criteria and get the best option as a result. They can use the platform for creating new installations or to optimise existing ones. PhoCa uses statistical models to provide the best design variant. The platform can be used for creating dynamic scenarios to control the entire installation.

Value proposition

Gradis can provide cost-effective design, which allows for low energy costs. Typical projects implemented for commercial partners provide 10-40% of cost reductions compared to existing installations. The potential of dynamic control guarantees further improvement.
