About EvariLUX

EvariLUX is a powerful digital platform designed to address a wide range of context-sensitive outdoor lighting needs.  Typical applications include:

Digital Twin Illumination Analysis

  • EvariLUX generates a digital twin of detailed streetlight photometric analyses using factors like luminaire specifications, mounting height, and ground elevation to simulate lighting conditions across large areas. This tool achieves overnight what 20 lighting engineers can do in a month.

Streetlighting Master Planning (SLMP) and Corridor Studies and Asset Management

  • EvariLUX supports comprehensive streetlighting audits and master plans by creating digital twins of municipal lighting systems. It integrates existing utility data with enhanced data attributes to analyze areas that are over- or under-lit, helping cities optimize streetlight placement for safety, equity, and cost savings. This use has helped cities save on construction costs while also reducing collisions and improving overall safety​​​.

Environmental and Ecological Impact Assessment:

  • EvariLUX is designed to assess the ecological impacts of light pollution, focusing on sensitive habitats and species behaviors affected by artificial lighting. This includes studying the effects on migratory birds, nocturnal insects, and other wildlife. The platform integrates geospatial data with lighting performance metrics to create actionable insights, which is especially important for projects with biologically appropriate lighting standards​.

Safety and Equity Assessments:

  • The platform’s capabilities in illumination analysis allow cities to address lighting needs based on demographics and collision history, helping to create equitable lighting environments that improve pedestrian safety and enhance community aesthetics. EvariLUX has been used to develop lighting policies and plans with a focus on reducing light pollution, balancing energy efficiency, and improving security​​.

Data Visualization and Web-Based Application:

  • EvariLUX features a web-based application that makes data accessible to clients and non-technical stakeholders unparalleled by traditional lighting design software. This allows for real-time viewing and interactive engagement with lighting data, making it easier to communicate lighting design impacts to community members and decision-makers​​.

Frequently-Asked Questions

  • EvariLUX operates as a digital twin of a streetlighting system in a GIS environment - like Google Earth for streetlights. It integrates geospatial data with .IES files to create a 3D model of lighting systems.

  • To begin, you’ll need basic information about your streetlighting system, such as where your streetlights are, which fixture is installed at each location,  and the related .IES files. If any of this information is currently unavailable, Evari can help fill in these gaps.

  • EvariLUX can function without specific IES files by using industry-standard approximations and proxies or simulating the most probable lighting scenarios based on available data​​.

  • EvariLUX is the only illumination simulation software that can be scaled to model anywhere from 10 to 100,000 (or more)streetlights with ease. It uses ground topography to simulate real-world conditions, whereas all other illumination simulation software assumes the Earth is a flat plain - meaning EvariILUX delivers the most accurate representation of your real-world conditions.

    Most importantly, it bridges the gap between illumination design and all other geospatial data that stakeholders care about- like crash data, sensitive habitats, building footprints, crime records, sidewalk networks, bike lanes, school zones, and more.

  • EvariLUX is scalable, from supporting small-scale installations at a single site to modeling entire citywide networks, exceeding tens of thousands of fixtures​​.

  • With good data, a citywide streetlighting model can typically be delivered in just two weeks. Incomplete data inputs require more time and are estimated on a case-by-case basis.

  • EvariLUX outputs are horizontal illuminance in lux or footcandles. It incorporates factors like dirt depreciation, lumen depreciation, and tilt into its simulation engine to produce accurate photometric analyses​​. Veiling luminance is also possible with information on surface reflectances.

    Vertical illuminance and luminance are in the EvariLUX product roadmap.

  • Primary deliverables include a web-based, password-protected interface of the illumination model, allowing clients to pan around in a virtual world of their streetlighting system. GIS-compatible datasets, analytical maps, and data reports are also featured options.

  • Through customized solutions, EvariLUX can integrate seamlessly with existing network lighting controls (NLCs), asset management systems (i.e. OpenGov), and GIS platforms like Esri, ensuring compatibility with your existing workflows​​.

  • Costs are project-dependent and typically quoted based on  your specific scope, data requirements, and deliverables. EvariLUX models with complete input databases are typically priced $1-4 per streetlight. Consultation with Evari is recommended ​​to establish more detailed pricing.
