Ventilated Facade: How Much Do You Really Save on Energy & How to Calculate ROI?
A ventilated facade isn't a cost — it's an investment that pays back. Here are concrete numbers: how much you save, when it pays off, and which material to choose.
The initial investment in a ventilated facade is higher than for a classic ETICS plaster system. But here's the question investors forget to ask: how much does this facade save — and when does the investment pay off?
The answer: faster than you think. Here are the numbers.
How does a ventilated facade save energy?
Ventilated Facade Cross-Section
The key is the air gap between the cladding and thermal insulation. In summer: hot air rises naturally through convection — the facade cools the building without air conditioning. In winter: still air acts as additional insulation. Result: 25-30% lower heating and cooling costs.
Cladding comparison
| Material | Price (€/m²) | Durability | Maintenance | Aesthetics |
|---|---|---|---|---|
| HPL panels | 100-140 | 25-30 yrs | Minimal | ◆◆◆ Modern |
| Aluminum panels | 130-180 | 40+ yrs | Low | ◆◆◆◆ Premium |
| Ceramic tiles | 170-250 | 50+ yrs | Almost zero | ◆◆◆◆◆ Luxury |
| Natural stone | 200-400 | 100+ yrs | Low | ◆◆◆◆◆ Classic |
| Fiber cement boards | 80-120 | 30+ yrs | Low | ◆◆◆ Functional |

Ventilated facade vs. ETICS — why investors increasingly choose it
| Feature | ETICS (EPS + plaster) | Ventilated facade |
|---|---|---|
| Price | 40-70 €/m² | 100-250 €/m² |
| Durability | 15-20 yrs | 40-60+ yrs |
| Maintenance | Every 5-10 yrs | Almost zero |
| Moisture/cracks | Common after 5 yrs | No issue |
| Energy savings | 15-20% | 25-30% |
| Fire resistance | Limited | A1/A2 class possible |
| Fire barrier | No | Air gap = barrier |
Substructure — steel or aluminum?
RAKUŠIĆ manufactures steel substructures with hot-dip galvanizing (EN ISO 1461) that last as long as the cladding. Steel advantage: higher load capacity for heavier cladding (ceramic, stone), greater resistance to wind and seismic forces. Aluminum: lighter, for HPL and fiber cement boards on lower buildings.
