5. Cost, ROI and Financial Clarity

From completed Ekonod reference projects we know:

• • installation costs in traditional builds average about 310,000 SEK per apartment
  • decentralised systems achieved around 3 kWh/m²/year for domestic hot water
  • CO₂ emissions were reduced by around 50%
  • construction time fell from 18 to 15 months, saving about 700 SEK/m² in financing
  • risk buffers decreased from 5% to 2% due to factory-built precision
  • green-financing yield compression increased asset value by about 3,290 SEK/m²

These are the numbers that drive the calculator.
Your output reflects real, measured performance – not marketing.

For developers

• faster build, fewer conflicts, predictable budgets
For owners
• Lower lifecycle cost and insulation from rising energy prices
For investors
• ESG-aligned returns and quantified value creation
For municipalities
• verified climate impact to support planning and financing

Default values follow Swedish benchmarks:

• Construction cost: 27,000–38,000 SEK/m²
• Installation share: 25–35 percent
• CO₂ pricing: 100 €/ton today rising to 150 €/ton by 2030
• Energy and CO₂ based on verified measurements

Every parameter can be customised. The calculator adapts to your project while staying grounded in real data. The Ekonod Economic Impact Calculator removes guesswork. With a few inputs, you get clear, credible financial insight instantly. It is more than a tool. It is a confidence engine for smarter, lower-risk decisions.
