Frequently Asked Questions
We answer the most important questions about the process, costs and funding options.
The iSFP is a BAFA-funded advisory tool for residential buildings. It shows a step-by-step renovation pathway with concrete measures and costs. Those who renovate under iSFP receive 5% more funding per individual measure (BEG WG).
When selling, letting or re-leasing, an energy certificate is legally required — for residential and commercial buildings. We create demand and consumption certificates in compliance with GEG.
The consulting costs are BAFA-eligible (BEU for residential buildings, BEW for commercial buildings) — up to 80% of the consulting costs. In the free initial consultation, we clarify scope, costs and funding options transparently.
Yes — owners, landlords, housing associations and businesses can receive funding. For residential buildings, BEG WG applies; for commercial and industrial buildings, BEG NWG or BAFA BEW. We advise you on the optimal programmes.
For non-SMEs, an energy audit is legally required every 4 years. It systematically analyses energy flows in buildings, production and fleet. Sustainari conducts certified audits — BAFA-eligible for SMEs.
Businesses can have up to 80% of energy consulting costs subsidised via BAFA BEW. For structural measures, BEG NWG is available. SMEs can also have the BAFA energy audit funded.
