Is your building adequately prepared to meet the GACS/BACS obligations?
From 2026, large buildings (≥ 290 kW) must have building automation in place.
Wingardium Energy guides you from a free scan to full implementation — and connects it to on-site generation and storage wherever possible.

What is GACS/BACS?
The European EPBD III/IV directive gradually obliges building owners to adopt Building Automation and Control Systems. A correct GACS/BACS class — minimum class C for existing buildings, class B recommended for new builds — can deliver 20 to 40% in energy savings, and is also linked to ETS2 carbon pricing from 2027.
Two phases, two deadlines. Phase 1 applies from 2026 for installations above 290 kW. Phase 2 follows in 2029 for installations above 70 kW. Both apply across Belgium, the Netherlands, Luxembourg, Spain, Italy and Norway — with local nuances per country.
Don't confuse the two: the 70 kW threshold in 2029 is a separate obligation from the automatic lighting-control requirement for new non-residential buildings in 2028. Two rules, two deadlines — we help you keep them apart.
