Hello,
to my surprise, we managed to hit the target exactly with our house planning for KfW 55. Since the repayment subsidies became more attractive from 04/01/16, I also took a look at KfW 40/40+.
Roughly about the house:
Single-family house with approximately 138 sqm (1,485 sq ft), basement for utility rooms, ground floor, and attic. Gable roof with 18°. Monolithic construction with controlled residential ventilation and an air-to-water heat pump.
The KfW 40+ information sheet states:
- A renewable energy-based power generation system
- A stationary battery storage system (electricity storage)
- A ventilation system with heat recovery
- A visualization of power generation and consumption via an appropriate user interface
So, would a photovoltaic system with battery storage possibly be enough to qualify for KfW 40+?
With a 15,000 € grant, that wouldn’t be a significant additional cost.
Best regards,

38cm (15 inches) plus facing bricks. Today is somehow not "my" day...
Good that you noticed

I still don’t understand? PB 240mm (9.4 inches) with 0.12 and mineral wool 120mm (4.7 inches) with 0.032, then ventilated cavity and then facing brick? That results in a U-value of just about 0.16, or how is the double-skin wall meant? Yes – double-skin wall means a brick cladding; yes – 1 cm (0.4 inch) air gap and then facing bricks 11.5 cm (4.5 inches). And no, it results in a U-value of 0.13 W/m²K.

Where can I find this information? I can’t find anything…On the KfW website. For example, in program 153 under the “Conditions” tab.D
daniels8713 Mar 2016 16:55So, if I understand correctly, you would need to switch from 36.5cm (14.4 inches) to 49cm (19.3 inches) bricks to go from KfW55 to KfW40? (among other things)
