Refurbishment with life cycle greenhouse gas balance (LCA)

Course description

Funding is available for the energy-efficient refurbishment of residential buildings. This must not exceed a limit value for greenhouse gas emissions per square metre of net room area and per year over the life cycle of the building (50-year observation period).

The following information applies to applications submitted by 11 December 2025: Refurbishment with life cycle greenhouse gas balance (LCA)

For applications that are or have been submitted from 11 December, you will find all relevant information here:

The subsidy rate for refurbishments with a life cycle greenhouse gas balance is made up as follows:

15 per cent basic subsidy

The following surcharges can be added to the basic subsidy:

5 per cent worst-first supplement for buildings that have energy efficiency class G or H before refurbishment on the basis of a requirements calculation.

5 per cent of the eligible costs as a multi-family house supplement for buildings with 3 or more residential units.

5 per cent of the eligible costs as an area surcharge for buildings in areas that are designated as an "area with heat pump after refurbishment" or "test area" in the Municipal Heating Plan portal, as well as for a limited period in areas with an integrated neighbourhood approach or outreach energy advice.

You can also apply for bonus measures. Please refer to the guidelines to find out which bonus measures are eligible for funding.

Prerequisites

All binding information can be found in the directive.

Here are the most important points in brief.

The following applies to the Climate Neutral Buildings (FKG) funding programme:

• Funding is only available for buildings within the city limits of the City of Munich.
• The applicant is responsible for the investment costs. This means that all orders, invoices, etc. must be issued to the applicant and paid from their bank account. The funding amount is paid out exclusively to the applicant's bank account.
• The principle of "funding application before order" is mandatory for the application. No contract for the measure may have been awarded yet. If an order has been placed with the companies carrying out the construction work for which the application is to be made, this will prevent FKG funding!
• Among others, building owners and equivalent persons, for example usufructuaries, are eligible to apply. Further information on the group of applicants can be found under "Questions & Answers".
• The application must be submitted exclusively online in the municipal funding portal.

In addition, the following applies to refurbishment with a life cycle greenhouse gas balance:

• Measures can only be subsidised for existing buildings.
• The building must have an energy efficiency class of E, F, G or H based on a demand calculation prior to the refurbishment. The energy efficiency class is verified via the energy requirement certificate or an energy efficiency calculation of the condition prior to the refurbishment.
• Applications can only be submitted for an entire building, not for individual residential units.
• The use of fossil fuels (e.g. heating oil, natural gas, coal) or gaseous or liquid biomass or hydrogen leads to exclusion from the subsidy. Note: This does not apply to electricity from electrically driven heat pumps and SWM district heating.
• The installation of window and door frames made of tropical wood leads to the exclusion of subsidies.
• If funding from the City of Munich under the FKG and funding programmes from other funding bodies (e.g. the federal government or the Free State of Bavaria) is used at the same time, the requirements of these funding programmes must be observed. In particular, their provisions on the cumulative nature of the funding programmes apply. If you have any questions regarding the possibility of cumulation, please contact the responsible office at the respective funding organisation.

Required documents

No documents are required when submitting the application.

After completion of the construction project(s), the following documents must be uploaded. In the funding portal, uploading these documents is called "Submit proof of use":

If the application is to be submitted by an authorised person representing the applicant, the power of attorney form must be submitted.

• Proof of authorisation to apply. Example: A private individual submitting the application themselves must upload their ID. For WEG, see WEG subpage.
• GEG calculation including building component list with area and U-value calculations as well as a description of the technical system
• Proof of operating emissions based on the energy requirement parameters of the existing building
• Calculation of heated net room area in accordance with DIN 277
• Documentation of the life cycle assessment of the building on the basis of a component list with the refurbished components of KG 300 and 400 that are relevant in terms of energy.
• Sustainability certificates for wood
• Building plans on the basis of which the energy requirement calculation was prepared.
• Completed form " Declaration of life cycle THG balance sheet"
• Confirmation from a specialised company that hydraulic balancing has been carried out using the confirmation form for an efficiency house (residential building) from the "Spitzenverband für Gebäudetechnik" (VdZ-Forum für Energieeffizienz in der Gebäudetechnik e. V., www.vdzev.de/broschueren/formulare-hydraulischer-abgleich).
• List of eligible investment measures and investment costs
• All project-related, detailed calculations
• Proof of product-specific characteristic values

A summary of the documents to be submitted can be found in the checklist Refurbishment with life cycle GHG balance sheet.
