Evari GIS Consulting’s EvariLUX digital twin visualization tool offers a new approach to comprehensive project planning, deployment, and post-installation validation that dramatically lowers total cost of ownership (TCO), while substantially increasing stakeholder satisfaction.

The EvariLUX Lighting Digital Twin

The EvariLUX digital twin visualization tool developed by Evari GIS Consulting provides a holistic and integrated view into regional lighting design by supporting the user needs of all major stakeholders through its integration of Outdoor Lighting Industryphotometrics with traditional Geographic Information Systems’ (GIS) 3D, web-based environment. EvariLUX was developed in response to the needs of dozens of Evari GIS outdoor lighting clients over the last ten years, totaling over two million lights supported, and represents a major step forward in breaking down some of the barriers faced when developing, presenting, and implementing citywide lighting designs.

Input on the tool has been received from the design community, city officials, and the public. Using existing pole and proposed fixture information, an EvariLUX visualization can help inform:

  • Design and Engineering professionals who are often tasked with citywide design that requires more than simple typical applications. EvariLUX provides a quick solution to model the way in which proposed designs illuminate a digital copy of the project area. EvariLUX can be used to enhance AGI32-based designs by supporting topographic elevations, parcel databases and other GIS/CAD layers as well as three-dimensional representations of buildings and other structures.
  • Installation and Commissioning – EvariLUX drives sophisticated asset management, so fixtures and related components are installed correctly, and in the right location. For example, to satisfy a requirement that light reaches the keyhole of a front door but not above.

  • Post Installation Verification and Validation – EvariLUX can manage operational data from the date of installation to any user-defined points in the future. This approach allows monitoring of lumen degradation from dirt depreciation, electrical anomalies, operational wear, and various other factors.

EvariLUX Value Proposition

EvariLUX digital twin solutions satisfy the needs listed above, and many others. These include:

  • Reduction in Liability Issues: By providing and documenting the level of light in a more accurate and intuitive interface.
  • Energy Conservation: By knowing exact topographies, building and structure sizes and locations as well as three-dimensional fixture position, lighting levels can be adjusted and often reduced to optimal performance levels to ensure that the correct and safe amount of light is supplied to the area.
  • Code Compliance: For both private and public outdoor lighting applications, local, state and national building codes must be supported. EvariLUX’s unique approach can enhance code compliance and can reduce the cost of compliance.

Outdoor Lighting Industry

  • Fast and Accurate Design Generation: By using three-dimensional maps, GIS information, and IES light distribution files.
  • Greater Efficiency: By responding to residents’ complaints to new designs and then installing and commissioning - for example, potential light trespass problems can be identified before the new fixture is installed.
  • Environmental Support: The need to support location specific environmental concerns, in terms of turtle habitat, migratory birds, and even agricultural issues.
  • Enhanced Public Support: The need for enhanced public and other stakeholder support of proposed projects achieved through approval of digital twin visualizations.
