LCA and LCC
Life-cycle assessments for climate (LCA) and cost (LCC) — decision support for material and technology selection and for refurbishment vs. new build.
Lifecycle assessments make it possible to compare alternatives on criteria that matter over time: total environmental impact and total cost over the building’s lifetime.
LCA — lifecycle assessment for climate impacts
- Calculation of greenhouse gas emissions by phase (A1–A3, A4–A5, B1–B7, C1–C4)
- Comparison of alternatives: material choices, structural solutions, energy systems
- Basis for BREEAM credits, taxonomy reporting and CSRD
- Assessment of refurbishment versus demolition and new build
LCC — life‑cycle cost
- Capital, operating, maintenance and end‑of‑life costs
- Net present value (discounted) over the chosen analysis period
- Comparison of technical solutions with different cost profiles
- Sensitivity analysis for energy price, interest rate and lifetime
Use cases
- Early‑stage decisions where genuine alternatives exist
- Refurbishment strategy for portfolios
- Decision support for the heating plant, façade, ventilation or solar PV
- Basis for green financing and sustainability reporting
The analyses deliver most value when carried out early — before the solution is locked in. We prioritise delivering quickly enough for the numbers to actually influence the decision.
