BEG Nichtwohngebäude

BEG Nichtwohngebäude is the part of the federal funding for efficient buildings that addresses non-residential buildings. The Federal Ministry for Economic Affairs and Energy is responsible; the funding is awarded by KfW. The current directive has applied since 21 July 2026 and runs until 31 December 2030. You receive the funding as a loan with a repayment subsidy.

Unlike funding programmes that pay out a pure grant, the refurbishment of non-residential buildings runs through loan financing here. The ceilings are tied to the net floor area of your building: up to €2,000 per square metre and a maximum of €10 million per project if you reach a new efficiency-building level.

What stands out is the depth of financing. Within these ceilings, KfW finances up to 100% of the eligible costs. Even a very capital-intensive refurbishment can therefore be covered entirely by the promotional loan.

Owners and investors in non-residential buildings are eligible to apply. You are funded if you refurbish an existing non-residential building or buy a newly refurbished efficiency building. Refurbishment and purchase are the two routes into this programme.

The hard condition is the age of the building. At the time of application, the building application or building notification for the existing building must be at least five years old. You can check this date yourself; it is on your building application or notification. If it is more recent, funding through this programme is not possible.

Two further conditions apply. After refurbishment, your building must fall within the scope of the GEG (Building Energy Act). And you, as the borrower, must actually bear the eligible costs yourself.

Funding goes to the energy-related refurbishment of your non-residential building into an efficiency building. The purchase of a newly refurbished efficiency building is funded as well. The refurbishment must go far enough for your building to reach a new efficiency-building level. The maximum amount depends on exactly that.

Eligible items are the energy-related refurbishment measures on the building and the costs of eligible ancillary measures. You can include VAT in the financing if you are not entitled to deduct input tax. Individual measures have their own cost framework of €500 per square metre of net floor area and calendar year.

You may combine the funding with other programmes as long as the same costs are not funded twice. Within the federal funding for efficient buildings there are further components that can be combined with it. Where federal funds are involved, the usual funding limits apply.

You receive a KfW promotional loan plus a repayment subsidy. The loan is paid out and repaid. The repayment subsidy reduces the amount you have to repay. This route is not a pure grant without repayment.

Up to 100% of the eligible costs is financed, limited by the programme’s ceilings. These limits follow the net floor area: up to €2,000 per square metre and a maximum of €10 million per project in total if your building reaches a new efficiency-building level.

On 21 July 2026, the funding rates for the repayment subsidies were reduced across the board by 10 percentage points. Anyone refurbishing today therefore works with lower rates than before that date.
