6. • 20% of all electricity consumption
‒ Up to 40% SMEs energy bill
‒ Up to 60% for logistics and warehouses
‒ Up to 70% for schools and public buildings

7.  Switching towards more energy-efficient light bulbs reduces
energy consumption
X You still consume energy (that gets more & more expensive)…
X Costly investment…
X Power cuts require operations to shut down…

8. “To offer companies daylight in such a way that they are able
- To switch-off their artificial lighting as long as possible…
- Without external factors…
- To generate monitored savings…
- And a higher productivity…”

9. • ‘Passive’ daylight/skylight systems (e.g. light sheets) only capture
“direct light” above a 30° degrees* sun position
‒ Rise to 30° degree angle takes approx. 1,5-2 hours to reach
• EcoNation’s solution: autonomous active daylight system based on a mirror
which is continuously positioning itself to the brightest spot in the sky
‒ To capture low-lying sun and brightest spot on cloudy days
*Based on EcoNation R&D simulations
