How Germany’s KfW 296 Program Makes Sustainable Homes Affordable

Are you dreaming of a greener home without the heavy loan rates? The KfW 296 program is all you need to know about. This blog will break down what this funding opportunity is all about and how we at Archiformus are already applying these standards in our own projects, making low impact homes both achievable and affordable.

What is the KfW 296 Program?

Building or buying a home is one of the biggest investments most people make, and costs can rise quickly. The KfW 296 program, officially known as Klimafreundlicher Neubau im Niedrigpreissegment, was launched to make climate friendly, energy efficient homes more accessible in Germany. It offers low interest loans of up to €100,000 per housing unit, repayable over up to 35 years.

The program supports both those constructing a new home and those purchasing a newly built one.

It even includes planning and consultancy costs, such as fees for certified energy efficiency experts, helping homeowners start strong from the very beginning.

What Does “Energy Efficient” Really Mean?

To qualify for KfW 296, your home must meet the Efficiency House 55 standard. It should use no more than 55% of the designated benchmark for heating, hot water, and ventilation, and loses less than 70% of the standard heat through its walls, openings, and roof.

Fossil fuel and biomass based heating systems are not permitted. The home must rely on renewable systems.

The design also needs to prove that its greenhouse gas emissions do not exceed 24 kilograms of CO₂ per square meter per year, ensuring that it remains climate friendly throughout its life cycle.

On top of this, life cycle costs must remain below the set threshold, proving the project is economically efficient in the long run.

What Changed in September 2025?

Two key updates made the KfW 296 program easier to access. First, the construction cost limit was raised by about 18%, which means more projects can now qualify. So if your project closely missed the previous affordability criteria, you are probably qualified now.

Secondly, an open plan kitchen is now counted as a room. This might seem like a small adjustment, but it matters. The KfW standards require a certain number of rooms in proportion to the total living area, setting a balance between space and efficiency. By including open kitchens in this count, most projects with such modern layouts are now eligible.

Borrowers can draw up to 100% of the loan within 12 months, with an option to extend to 24 months if needed. Early repayment is allowed, though prepayment fees may apply.

Klistostraße: A KfW 296 compliant project by Archiformus

Klistostraße, Berlin

We are proud to introduce our own KfW 296 certified project Klistostraße, a residential development featuring 23 modern apartments, located in Berlin.

From the very beginning, the project was planned to align with KfW 296 standards, not just architecturally but also in terms of materials, energy use, and life cycle performance.

Klistostraße meets the Efficiency House 55 benchmark, maintains the greenhouse gas emissions limit, and avoids all nonrenewable heating systems. Every step, from facade design to technical building systems, was guided by efficiency and sustainability.

Because of this careful planning, buyers automatically qualify for KfW 296 loans when purchasing a unit in this building. This makes home ownership both responsible and attainable.
