Energy resilience takes centre stage in 2026 I n 2026, one theme is dominates conversations across the built function when the power goes out?” That question changes everything. Lighting designers, engineers, consultants, and suppliers must now integrate technical excellence with energy strategy insight.
environment, infrastructure planning, and commercial development sectors: energy resilience. For South Africa, this is not a trend; it is a necessity. Years of grid instability, load-shedding, rising electricity costs, and increasing pressure on infrastructure have fundamentally transformed how buildings are designed, specified, and managed. Energy resilience is no longer an optional extra. It is now a fundamental requirement. And at the heart of this transformation sits the lighting industry. The Shift in expectations for lighting professionals. With this shift comes greater responsibility. Lighting professionals in 2026 are expected to: • Understand backup power integration • Design systems compatible with renewable energy sources • Specify products that maximise efficiency and longevity • Advise clients on the total cost of ownership • Ensure compliance with evolving safety and efficiency standards Clients are no longer asking, “What fitting should we use?” They are asking, “How will this building
Smart, Sustainable, and Resilient Design Resilience is not just about surviving outages. It involves designing systems that are:
• Energy intelligent • Digitally integrated
• Scalable for future upgrades • Sustainable in the long term
Smart lighting controls, daylight harvesting, occupancy sensors, and remote monitoring are becoming standard expectations. Emergency lighting must not only meet regulations but also perform reliably in real-world conditions. In short, resilience is redefining what “good lighting design” means. IESSA’s Role in supporting the industry As the premier lighting society in South Africa, the Illuminating Engineering Society of South Africa (IESSA) acknowledges that the demands on lighting professionals are changing swiftly. Our role is to: • Mentor and guide professionals across
Those who embrace innovation, expand their technical capabilities, and align with industry best practices will not only stay relevant, but they will also lead. IESSA represents South Africa at an international level and acts as the National Committee of the CIE (Commission Internationale de l’Eclairage). South African experts in various fields of lighting technology serve on CIE international committees responsible for developing standards related to different aspects of illumination. Membership of IESSA is available to both individuals and organisations involved in the lighting industry of South Africa. To join IESSA, you must be a Lighting Professional. Group membership is open to any educational, scientific, technical, professional, institutional, public, commercial, municipal, or parastatal entity actively engaged in the lighting sector. If you would like to learn more about IESSA and the benefits of becoming a member, please email us at info@iessa.org.za
all career stages • Provide access to industry-relevant training and technical knowledge • Facilitate conversations around best practice and innovation • Support compliance and standards awareness • Foster collaboration across the lighting ecosystem Energy resilience is not a challenge any professional can tackle alone. It demands shared expertise, ongoing learning, and industry-wide cooperation. Through our programmes, conferences, and CPD opportunities, IESSA remains dedicated to supporting lighting professionals in staying ahead of regulatory updates, technological developments, and market needs. Moving forward in 2026 As we move further into 2026, energy resilience will continue to shape how buildings are powered, designed, and experienced. For lighting professionals, this presents both a challenge and an opportunity.

Lighting controls and automation: the bright future D emand for intelligent, energy-efficient lighting is rising across construction and building management. For electrical contractors, expertise in lighting controls and automation is now vital. for flexibility. They are commonly found in commercial offices and classrooms. • 3. Networked Lighting Controls (NLCs): These advanced systems connect
Modern lighting controls enable precise adjustment of lighting levels, scheduling, and even colour temperature—leading to optimised energy use, enhanced occupant comfort, and longer fixture lifespan.
multiple devices over a wired or wireless network, offering centralised control and monitoring. NLCs can be integrated with HVAC, security, and other building systems, enabling comprehensive automation and data analytics. Benefits for contractors and clients • Energy Savings: Lighting controls can reduce energy usage by 30-60% compared to manual switching, especially when combined with LED technology. This translates to lower utility bills and an improved sustainability profile for clients. • Code Compliance: Many regions require lighting controls to comply with energy codes such as ASHRAE 90.1 and Title 24. Contractors familiar with these requirements can ensure projects remain compliant, avoiding costly rework. • Enhanced User Experience: Automated controls provide occupants with optimal lighting for different tasks and times of day, increasing comfort and productivity. • Maintenance and Monitoring: Advanced systems offer remote monitoring and diagnostics, enabling contractors to deliver ongoing service contracts and
Mastering these technologies creates new business opportunities, increases project value, and aligns your services with the future of smart buildings. The basics of lighting controls Lighting controls are devices and systems that manage lighting in a space. At their simplest, they include manual switches and occupancy sensors; at their most advanced, they consist of networked systems that connect with building automation platforms. Modern lighting controls enable precise adjustment of lighting levels, scheduling, and even colour temperature—leading to optimised energy use, enhanced occupant comfort, and longer fixture lifespan. Types of lighting control systems • 1. Standalone Controls: These are basic systems, such as dimmers, timers, and occupancy/vacancy sensors. They are easy to install and ideal for retrofits or isolated rooms. • 2. Room-based Controls: These systems manage lighting in a single room or zone, often using wireless technology

industry organisations. Staying up to date on coding standards, system interoperability, and cybersecurity best practices is crucial. Partnering with experienced lighting designers can also help deliver optimal results. Conclusion Lighting controls and automation are a key growth sector in the electrical industry. Contractors who adopt these technologies position themselves as innovative professionals prepared to meet the demands of modern buildings. By providing expertise in lighting automation, you not only enhance your project's value but also support energy efficiency and occupant well-being.
Emerging technologies and trends The integration of IoT (Internet of Things) is revolutionising lighting controls. Wireless protocols such as Zigbee, Bluetooth Mesh, and Wi-Fi make installation and scaling easier. Cloud-based platforms allow remote access and provide advanced analytics, while voice and mobile app controls increase convenience for users. Human-centric lighting, which adjusts colour temperature and brightness throughout the day, is becoming popular due to its health and wellness benefits.
