From LYS A/S
The Future of Sustainable Lighting Management
From Pioneer to Sustainability Trendsetter
For over 20 years, LYS A/S has developed lighting solutions with one clear focus: to create systems that not only deliver perfect light, but also make sustainability measurable, controllable, and profitable. Our journey began with a simple realization—traditional lighting systems could not deliver the intelligence, data, and control that modern retail businesses need to achieve their ambitious environmental goals.
Today, LYS Software System stands as a complete sustainability platform that helps global brands achieve 44-67% energy savings, automatic ESG reporting in compliance with GHG Protocol, GRI, CSRD, and ESRS, and documented progress toward carbon neutrality. But our approach is about much more than technology—it is about understanding people, their needs, and how intelligent lighting control can create value for all stakeholders.
LYS Software System: The Heart of Our Sustainability Solution
Designed with People and the Planet in Focus
LYS Software System is not just a lighting control system—it is the result of decades of experience listening to customers, understanding their challenges, and developing solutions that work in the real world. Like the best lighting control systems, we focus on what matters: user-friendly operation, reliable performance, and results that can be measured.
Our philosophy is simple: Sustainability must be easy to implement, easy to manage, and easy to document. That is why we designed LYS Software System to deliver comprehensive functionality without complexity—from real-time energy monitoring to automatic ESG reporting, all accessible through intuitive interfaces that make complex settings easily accessible.
Real-Time Energy Monitoring: Visibility Creates Action
LYS Software System monitors energy consumption for every single fixture in real-time, aggregated across stores, regions, and globally. This gives retail brands immediate visibility into where energy is consumed, identifies inefficiencies, and enables data-driven decision-making.
Unlike traditional systems, where energy consumption is only known through monthly electricity bills, LYS delivers granular data down to fixture level. If a store in Tokyo consumes more energy than expected, it can be identified and addressed immediately—not months later. This real-time transparency is the foundation for effective energy management and continuous improvement.
Why this matters for global brands:
For retail chains with hundreds or thousands of stores, lighting often represents 30-50% of total electricity consumption and a significant portion of Scope 2 CO2 emissions. Without granular, real-time data, it is impossible to identify savings opportunities, verify progress, or report credibly to investors and regulators.
Automatic ESG Reporting: From Data to Compliance
LYS Software System automatically generates ESG reports in compliance with the most recognized international standards: GHG Protocol, GRI Standards, CSRD, and ESRS. The system calculates:
•Scope 2 CO2 emissions from lighting based on local grid emission factors
•Energy intensity (kWh per m² or per revenue)
•Energy savings compared to baseline or previous periods
•Renewable energy share where relevant
•Circular economy metrics (component replacement, recycling)
These reports can be exported directly to companies' sustainability management platforms or included in annual sustainability reports without manual data processing. This eliminates risk of errors and dramatically reduces the resources required for ESG reporting.
Our approach to reporting:
We know that ESG reporting can be overwhelming, especially for companies with global operations. That is why we designed LYS Software System to handle the complexity automatically—different emission factors across countries, different reporting methods (location-based vs. market-based), and different standards. The system ensures consistent, accurate reporting across jurisdictions, so sustainability teams can focus on strategy instead of data collection.
Adaptive Control: Intelligent Energy Optimization
LYS Software System implements adaptive lighting control based on real-time data from sensors. This is where our 20+ years of experience with lighting control truly shines—we understand how to create systems that respond quickly, dim smoothly, and deliver reliable control without oscillation effects.
Presence Detection:
Lighting reduces to background level (30%) when no customers are present, rises to 50% with low traffic, and 100% with high traffic. Transitions are smooth and imperceptible to customers and employees.
Daylight Integration:
Lighting adjusts automatically based on available daylight to maintain optimal light levels while minimizing energy consumption. Our central daylight measurement head ensures precise control without oscillation.
Zone Division:
Different areas in stores are controlled independently based on actual use. This ensures energy is never wasted in areas without activity, while customer-facing zones always have optimal lighting.
This intelligent control delivers 44-67% energy savings compared to conventional systems, which directly translates to reduced Scope 2 emissions and progress toward carbon neutrality goals.
Predictive Maintenance: Maximize Lifespan, Minimize Waste
LYS Software System monitors each fixture's performance and predicts when components need replacement. This enables proactive maintenance that extends product lifespan and reduces waste—a core principle of circular economy.
When an LED module or driver approaches its end of life, the system automatically orders spare parts and schedules replacement. This ensures maximum utilization of each component and minimizes premature disposal. The system also documents all component replacements and recycling, providing data for circular economy reporting required under ESRS E5.
Designed for electrical consultants and installers:
We know that even the best system is only as good as its installation and maintenance. That is why we designed LYS Software System to support immediate testing after installation without prior commissioning or addressing. Our modular design makes component replacement quick and simple, reducing maintenance costs and downtime.
LYS Gen 4 LED Technology: Perfect Partner to Software
LYS Software System delivers its full value when combined with our Gen 4 LED technology—designed in close collaboration with the world's best OEM factories and component manufacturers over two decades.
170+ Lumens per Watt: World-Class Efficiency
With over 170 lm/W efficiency, our Gen 4 technology ranks at the absolute top globally. This means the same light level can be achieved with significantly lower energy consumption compared to older LED systems (typically 100-130 lm/W) or conventional technologies.
For a global retail chain with 1,000 stores, upgrading to LYS Gen 4 technology combined with LYS Software System can reduce annual energy consumption from lighting by 10-15 million kWh, equivalent to 5,000-7,500 tons CO2 depending on grid emission factors.
CRI >90 Color Rendering: No Compromises on Quality
High color rendering (CRI >90) ensures products are presented optimally, which is critical for retail brands. We prove that sustainability does not require compromises on customer experience—on the contrary, optimal lighting improves both sales and environmental performance.
50,000-70,000 Hour Lifespan: Long-Term Value
Extremely long lifespan reduces replacement frequency, minimizing both waste and maintenance costs. For global brands, this means fewer resources spent on logistics, installation, and disposal—all factors that contribute to Scope 3 emissions.
Biologically Optimized Spectrum: People at the Center
Our spectrum is optimized for both employee well-being and energy efficiency. By supporting the circadian rhythm, employee fatigue is reduced and productivity improved, contributing to the social dimension of ESG.
Anti-Glare: Comfort for All
The LYS spot series has integrated anti-glare technology (UGR <16) that ensures both employees and customers experience optimal comfort. No glare means better work environment, reduced eye strain, and a more pleasant shopping experience.
Modular Design: Future-Proof and Circular
All LYS fixtures are designed with replaceable LED modules, drivers, and optical components. This modular design is not just a technical feature—it is a fundamental part of our sustainability philosophy and our commitment to circular economy.
Replace Components, Not Entire Fixtures
When a component reaches its end of life, only that component is replaced—not the entire fixture. For global brands with hundreds of thousands of fixtures, this represents a dramatic reduction in electronic waste. A traditional "use-and-discard" approach would generate thousands of tons of e-waste over a decade, while our modular approach reduces this by 80-90%.
Compliance with EU Ecodesign Directive
Our products fully comply with the EU Ecodesign Directive (Regulation 2019/2020), including requirements for non-destructive disassembly, replaceable light sources and drivers, and EPREL registration. This ensures global brands' lighting installations are compliance-ready for current and future EU regulations.
Upgradability: Extend Investment Lifespan
When new technology becomes available, existing LYS fixtures can be upgraded with new LED modules instead of complete replacement. This extends the investment's lifespan from typically 10-15 years to potentially 25-30 years, reducing both economic and environmental costs.
How LYS Software System Supports International Sustainability Standards
LYS Software System is designed for full compliance with the most recognized international sustainability standards. This is not accidental—we have worked closely with sustainability experts, standardization organizations, and our customers to ensure the system delivers precisely the data and documentation required.
GHG Protocol: Automatic Scope 2 Calculation
LYS Software System automatically calculates Scope 2 emissions from lighting based on actual energy consumption measured in real-time, local grid emission factors (updated annually), and location-based or market-based methods according to the company's choice.
For companies with operations in many countries, the system automatically handles different emission factors and reporting methods, ensuring consistent and accurate reporting across jurisdictions.
GRI Standards: Direct Data Export
LYS Software System supports reporting for GRI 302 (Energy), GRI 305 (Emissions), and GRI 306 (Waste). Data can be exported directly in GRI-compatible formats, eliminating manual data processing and reducing risk of errors.
CSRD and ESRS: Future-Proof Compliance
LYS Software System delivers the granular data and documentation required for ESRS compliance, including ESRS E1 (Climate Change), ESRS E2 (Pollution), and ESRS E5 (Resource Use and Circular Economy). This dramatically reduces the burden on global brands' sustainability teams and ensures companies are ready for CSRD reporting.
ISO 14025 and EN 15804: Verified Lifecycle Data
We have prepared Environmental Product Declarations (EPDs) in accordance with ISO 14025 and EN 15804 for our products. These EPDs document environmental impact throughout the product's lifecycle and provide verified, third-party validated data for Scope 3 reporting.

Implementation: Designed for Success
We know that even the best technology only creates value if implemented correctly. That is why LYS Software System implementation follows a structured, proven process:
Phase 1: Assessment and Baseline
We conduct a comprehensive sustainability assessment of existing lighting installations, measure or estimate current energy consumption, calculate Scope 2 emissions, identify savings potential, and document ROI. This baseline is critical for later documenting progress.
Phase 2: Pilot Implementation
A pilot implementation in 5-10 selected stores demonstrates value before full rollout. 3-6 months of data collection documents actual savings, software reporting is tested and adapted, and pilot results are presented to stakeholders. The pilot phase reduces risk and delivers concrete data for the business case.
Phase 3: Global Rollout
Based on pilot success, LYS Software System is implemented globally. Stores are prioritized based on energy consumption or strategic importance, installation processes are standardized, we coordinate with local installation partners, and store personnel are trained. Global rollout is typically completed over 12-36 months.
Phase 4: Continuous Optimization
After implementation, LYS Software System ensures continuous optimization through real-time performance monitoring, automatic adjustment of lighting control, monthly or quarterly ESG reports, and the ability to upgrade when new technology becomes available.
