Energy Resilience Takes Centre Stage in 2026
In 2026, one theme is dominating conversations across the built 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 changed how buildings are designed, specified, and managed. Energy resilience is no longer a value-add. It is now a core 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 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 function when the power goes out?”
That question changes everything.
Lighting designers, engineers, consultants, and suppliers must now combine technical excellence with energy strategy insight
Smart, Sustainable, and Resilient Design
Resilience is not only about surviving outages. It is about 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 baseline expectations. Emergency lighting must not only comply with regulations but perform reliably under real-world pressure.
In short, resilience is redefining what “good lighting design” means.
IESSA’s Role in Supporting the Industry
As the leading lighting society in South Africa, Illuminating Engineering Society of South Africa (IESSA) recognises that the demands placed on lighting professionals are evolving rapidly.
Our role is to:
- Mentor and guide professionals across 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 one professional can navigate alone. It requires shared expertise, continuous learning, and industry-wide alignment.
Through our programmes, conference, and CPD opportunities, IESSA remains committed to helping lighting professionals stay ahead of regulatory changes, technological advances, and market demands.
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 is both a challenge and an opportunity.
Those who embrace innovation, expand their technical capabilities, and align with industry best practice will not only remain relevant, but they will also lead.
IESSA represents South Africa internationally and thereby acts as the National Committee of the CIE (Commission International De L'Eclairage). South African Experts on various topics in the lighting technology field serve on the CIE international committees responsible for the development of standards for the different aspects of illumination.
Membership of IESSA is open to both individuals and organisations active in the lighting industry of South Africa. You need to be a Lighting Professional to join IESSA. Group membership is open to any educational, scientific, technical, professional, institution, public, commercial, municipal, or parastatal entity that is actively involved in the lighting industry.
