The iSFP process — from first call to finished report in 4 steps
The iSFP follows a clearly structured process. You know in advance what happens, who does what and when the report lands on your desk. From the first call to delivery, plan for 4–8 weeks.
1. Free initial consultation (30 minutes)
In the first step we clarify whether an iSFP makes sense for your building and your goals. You tell us what you have in mind — we listen, ask the right questions and frame the funding landscape. At the end you know whether and in what form an iSFP fits, what it costs and which funding may apply.
The initial consultation runs by phone or video. It is free and non-binding.
2. On-site inspection with stocktake
We come to your property and systematically capture the current energy condition: building envelope, windows, heating, ventilation, hot water and renewables where applicable. We review as-built documents and take additional measurements where needed for the calculation.
On request we run the inspection with drone support — useful for hard-to-access buildings and producing usable images of roofs and facades.
3. Energy modelling & measure planning
Back in the office, we model your building. We produce the energy balance using the federal methodology, define measure packages and bring them into an order that makes technical and economic sense. We check funding programmes in parallel so the roadmap also adds up financially.
4. Closing meeting & report handover
In a closing meeting we walk through the finished iSFP report together — findings, measures, costs, impact, funding paths. You receive the report digitally and as a printed copy. On request we register the iSFP in the funding portal so that subsequent single measures can claim the iSFP bonus.
