 KfW 

General Terms and Conditions for Investment Loans 
 -
Contractual relationship Principal Bank—End Borrower - 
 For KfW investment loans the following General Terms and Conditions for Investment Loans
in the Version for the contractual relationship between Principal Bank—End Borrower (AB-EKN) up to and including Clause 13 applies. For ERP loans and loans refinanced or subsidised from public budgetary
funds, the special provisions of Clause 14 apply in addition. For loans where the Principal Bank is granted liability exemption on the basis of a national or state guarantee, the special provisions of Clause 15 additionally apply. 

1. Use of funds 
 (1) The Loan may only be used to finance
the project for which the Loan was approved. The credit institution closing the Loan Agreement with the End Borrower (hereinafter the “Principal Bank”) must be informed immediately if the investment project or its financing change. 

(2) The End Borrower shall immediately and without being requested provide the Principal Bank on conclusion of the investments with evidence regarding the use
of the loan funds and the satisfaction of any conditions. 
 2. Draw-down of funds 

 

	1)	 The draw-down of the Loan – where applicable in partial amounts – from the Principal Bank may only
take place when this latter, within an appropriate deadline, can be apportioned for the specified purpose. Should it transpire after payment that correct use of the funds is not possible, the corresponding sums are to be immediately repaid to the
Principal Bank for forwarding to KfW. Renewed draw-down is possible when the aforesaid requirements are satisfied. Sub-paras. 2 and 3 of this paragraph do not apply if the Loan does not exceed the sum of
25,000 Euro. Sub-paras. 2 and 3 of this paragraph also do not apply for the last payment instalment of a loan when this does not exceed the sum of 25,000 Euro. The Principal Bank is entitled to set appropriate
minimum draw-downs. 


  

	2)	 Loan amounts may only be drawn down by natural persons as commercial or freelance end borrowers when these have
demonstrated their power to manage and represent the company or law firm, the practice or comparable to the Principal Bank. 


  

	3)	 Should grounds exist providing entitlement to terminate the Loan Agreement, the Principal Bank may refuse
payment of the loan funds. 


 3. Interest schedules 

The Loan shall accrue interest at the agreed rate. Interest calculation takes place applying the German business interest method (30/360 Method). Interest
payments are due quarterly in arrears on 31st March, 30th June, 30th September and 30th December of each year, unless the Loan Agreement specifies otherwise. 
 4. Costs and expenses

 The costs and expenses of the directly-refinanced credit institution and the Principal Bank are settled with the interest rate and the
program-dependent processing charges paid by KfW. Regardless of the provisions of sub-para. 1 any possible claim of the directly-refinanced credit institution or Principal Bank to reimbursement of expenses is
regulated by the provisions of the Law. Compensation for non-acceptance or early repayment may only be charged when KfW has concluded a corresponding regulation. Where a charge is possible, this shall be made
by the Principal Bank. 
 5. Repayment 
  

	1)	 The repayment instalments or annuities are due on the dates given in the Loan Agreement. Where with payment a
deduction is made from the nominal amount of the Loan, the deduction amount is a fee demanded by KfW independent of term, which is not reimbursed in the event of premature redemption of the Loan. 



 

	2)	 Loans with a 100% payment can only be repaid early to the Principal Bank against payment of an early prepayment
penalty to the Principal Bank unless expressly agreed otherwise. Loans with a payment of less than 100% may be repaid early partly or wholly at any time during the first fixed-interest period by giving 10 banking days’ notice to the Principal
Bank. Legal rights of termination remain unaffected by the above provisions. Any levied prepayment penalty may be charged by the Principal Bank within the legally-permitted framework. 



 

	3)	 Unscheduled partial repayments are fundamentally set-off against the
last repayments or annuities due under the redemption plan unless otherwise agreed with the End Borrower. 


 6. Default 

Should the End Borrower be in default on its payment obligations, the Principal Bank is entitled to claim default interest in accordance with the provisions of
the Law. 
 7. Securities 
  

	1)	 The Principal Bank assigns the claims deriving from the granting of the Loan against the End Borrower on their
coming into existence to KfW. The Principal Bank is entitled to collect the claims assigned to KfW until KfW declares the cancellation of this collection authorisation. The Principal Bank is moreover entitled to assign the securities created for the
Loan to KfW. After the security assignment to KfW the claims concerned are regulated by the security purpose agreed between the Principal Bank and End Borrower. Securities provided or created in future by the Principal Bank for a KfW-refinanced Loan
of the End Borrower serve – where a further purpose has been or will be legally agreed – to secure all credit claims of the Principal Bank assigned or to be assigned in future to KfW against the End Borrower. This also applies when the
security is provided by a third party. 















	2)	 The securities agreed for this Loan may not be used as a priority to secure other Principal Bank loans. Other
securities given or to be given in future to the Principal Bank by the End Borrower or to a third party for loans to the End Borrower not refinanced by KfW serve – where a further purpose has been or will be legally agreed – subordinately
to secure all credit claims of the Principal Bank against the End Borrower assigned or to be assigned to KfW. 


 8. Right of audit

 The KfW is entitled to inspect business records and books of account at the End Borrower, inform itself of the latter’s asset situation and
monitor the use of the loan funds under Clause 1 para. 1 on site. KfW may have these audits executed by a third party acting on its behalf. The costs of these audits shall be borne by the End Borrower, provided there is no agreement otherwise. KfW
shall ensure that any third party it engages shall also maintain confidentiality regarding such information. 
 9. Information obligations 

The End Borrower is obliged to notify the Principal Bank of any significant events that may influence the purpose of the Loan or adversely affect service of
the same. The Principal Bank is entitled to forward the information to KfW. 
 10. Submission of annual accounts 

Where not otherwise agreed, the End Borrower is obliged to submit its annual accounts with the necessary explanations only on request of the Principal Bank or
KfW. In the event of delay in the preparation of the annual accounts, the End Borrower shall initially submit the provisional figures. 
 11. Termination
for important reason 
  

	(1)	 The Principal Bank is entitled to terminate the Loan for immediate repayment at any time for an important
reason completely or for a partial amount, in particular when 


  

	a)	 The Loan has been illegally acquired, is not used for the specified purpose or the End Borrower regardless of
an additional deadline set by the Principal Bank has not enabled an audit of the use of the funds complying with the specified purpose, 


  

	b)	 The requirements for it being granted have changed or are subsequently no longer satisfied (for example sale of
the co-financed business or parts thereof, change in ownership or stake holding), 


  

	c)	 The End Borrower has provided incorrect details regarding its financial situation, 



 

	d)	 The End Borrower is in breach of an obligation assumed under the Loan Agreement, 



 

	e)	 There is a significant worsening in the financial situation of the End Borrower or the valuation of a provided
security or such is threatened and as a result the repayment of the Loan, even realising the securities, is placed at risk, 



	f)	 The scale of the overall outgoings estimated in the investment plan and scale of eligible costs is reduced or
the percentage of public finance increases. 


 Should the important reason consist of the breach of a contractual
obligation, termination may only take place after unsuccessful expiry of an additional deadline or warning, unless one of the grounds cited in § 323 para. 2 BGB does not exist. 

(2) In the event of partial termination (reduction) the repaid amount is fundamentally set-off against the outstanding
repayment instalments or annuities (proportional to the residual term of the Loan), unless otherwise agreed with the End Borrower. 
 12. Provision of
information 
 The Principal Bank is entitled to give KfW or a third party authorised by KfW unrestricted information, allow them to inspect
documentation and, for documentation purposes, provide the documentation. The provisions of this paragraph also apply for electronic archiving. 
 13.
Limitation of applicability 
 If the General Business Terms and Conditions of the Principal Bank are incompatible with these General Terms and
Conditions, the latter shall take precedence. 
 14. Special terms and conditions for ERP loans and loans refinanced or subsidised from public budgetary
funds 
 For ERP loans and loans refinanced or subsidised from public budgetary funds, the following additional special provisions shall apply, unless
the Loan Agreement specifies otherwise: 
  

	1)	 The Loan may only be drawn down pro rata with the other funds provided for in the finance plan. Only where the
latter is not available can the loan, by way of exception, also be used earlier. The draw-down of the Loan – where applicable in partial amounts – may only take place when the requested sums can be apportioned to the specified purpose
within 3 months. Should it transpire after payment that punctual use of the funds is not possible, the corresponding sums must be immediately repaid to the Principal Bank for forwarding to KfW. Renewed draw-down is possible when the above
requirements are satisfied. Sub-paras. 1, 4 and 5 of this paragraph do not apply when the Loan does not exceed 25,000 Euro. Sub-paras. 1, 4 and 5 of this paragraph also
do not apply for the last payment instalment of a Loan when this does not exceed the sum of 25,000 Euro. 















	2)	 Should the costs of individual items of the investment plan be reduced by 20% or more, the saved funds may only
with the prior permission of the Principal Bank be used to cover the increased costs of other eligible items. 


  

	3)	 The Supreme Court, under § 91 BHO is entitled to carry out audits. Moreover the competent Federal
Ministries or their agents are entitled to carry out the relevant audits. 


  

	4)	 Interest premium 



The agreed interest rate increases from the date following payment, to 5 percentage points above the respective base rate under § 247 BGB
if the Loan is illegally obtained, is not used according to the specified purpose, the End Borrower, regardless of any additional deadline set by the Principal Bank fails to enable an audit of the correct specified use or the End Borrower does not
use the funds within 3 months for the specified purpose and also does not repay the funds immediately to the Principal Bank. 
 If the prerequisites for the
granting of the Loan have subsequently changed or are not satisfied, the interest rate increases to 5 percentage points above the respective base rate under § 247 BGB from the time of change or failure to satisfy. 

Where the interest rate cited in the Loan Agreement is higher than the base rate plus 5 percentage points, the interest rate cited in the Loan Agreement shall
continue to apply. 
 15. Special terms and conditions for Loans where the Principal Bank is granted liability exemption on the basis of a national or
state guarantee 
 In the case of Loans where the Principal Bank is granted liability exemption on the basis of a national or state guarantee, the
Federal Supreme Court under § 91 BHO or the respective State Court of Audit is entitled under state regulations to carry out audits. Additionally the competent Federal or State Ministries or their agents are entitled to carry out the
corresponding audits.

Is a combination with other funding programmes possible? 

The combination of a loan from the KfW energy-efficiency programme – Energy-efficient construction and renovation with other subsidies (loans or
grants/subsidies) is fundamentally possible within the framework of the respective relevant EU subsidy limits, provided the total of the loans, grants or subsidies does not exceed the total of the eligible costs. The legal cumulation provisions must
be complied with (cf. “General Information Sheet on Subsidies”, Order Nr. 600 000 0065). 
 Heat generating systems for the use of renewable
energies are subsidised: 
  

	 	•	 	 Under the programme “Subsidisation of measures for the use of renewable energies in the heat market” of
the Federal Department for the Economy and Export Control (BAFA) (www.bafa.de) or

		 		 		  	Redemption

 Up to 100% of the eligible costs are financed 

The loan amount amounts to 
  

	 	•	 	 in general up to 25 million Euro per project. 



This upper credit limit can be exceeded where the project is particularly worthy of subsidy. 

Term 
 The following term variants are available with a
minimum term of 2 years: 
  

	 	•	 	 Up to 5 years with max. 1 year grace period (5/1), 



 

	 	•	 	 Up to 10 years with max. 2-year grace period (10/2),



  

	 	•	 	 Up to 20 years with max. 3-year grace period (20/3).



 Interest rate 
  

	 	•	 	 The loan is granted with a customer-tailored interest rate within the framework of the maximum interest rate of
the respective price class on the day of commitment. 


  

	 	•	 	 The interest rate is set taking into consideration the financial situation of the Borrower (creditworthiness) and
the value of the securities provided for the loan by the credit institution. 


 Here classification takes place into
KfW’s creditworthiness and collateral classes. Through the combination of creditworthiness and collateral class the credit institution allocates the promotional loan to a price class given by KfW. 

Each price class covers a band width with a fixed upper interest limit (maximum interest rate). The client’s individual interest rate
agreed between it and the credit institution may lie below the maximum interest rate of the respective price class. Information on determining the individual interest rate can be found in the KfW Information Sheet “Risk-adjusted Interest
System”, Order Nr. 600 000 0038. 
  

	 	•	 	 The interest rate is set for a maximum 10 year loan term. 



 

	 	•	 	 The price reduction from Federal funds applies for the first fixed-interest period, maximum 10 years.



  

	 	•	 	 For loans with a term of over 10 years KfW will offer your credit institution, before the end of the
fixed-interest period, an extension offer without price reduction from Federal funds. 


 The respective maximum interest rates (borrowing
and effective interest rates under the Law) can be found in the overview of terms and conditions for KfW funding programmes on the Internet at www.kfw.de/konditionen or by fax under (069) 7431-4214.

	4.	 The annual primary energy requirement (QP) and
the mean heat transition coefficients of the heat transfer enclosing areas of the building are to be calculated on the basis of the planned measures under the Energy Savings Regulation (EnEV) and DIN 18599 in force at the time of application. The
project parameters for the primary energy requirement of the reference building (QP REF) is to be determined on the basis of the details in Annex 2, Table 1 (without application of Line 1.0)
EnEV. The mean heat transition coefficients are to be calculated for the entire building under the rules of EnEV Annex 2. The interpretations of the “Construction Technology” Special Commission of the Construction Ministers Conference on
the EnEV (www.bbsr-energieeinsparung.de) shall be taken into consideration for the KfW Efficiency House calculations. 


  

	5.	 For KfW Efficiency Houses a ventilation concept is to be prepared in which the required fresh air flow
rate and the solution for implementation are specified. For implementation of the ventilation concept particular attention is to be paid to the measures required to prevent condensation and humidity damage. Furthermore for all KfW Efficiency Houses
attention is to be paid on the building shell to heat bridge-minimising design and execution of an airtightness concept. In the case of a hydraulically-driven water-fed heat supply system, hydraulic balancing
of the distribution system must be carried out. 


  

	6.	 In the case of the extension of a building by building parts for which there is an open connection with
the existing building, Efficiency House evidence must be provided for the entire building. Here all the standard requirements must be satisfied for the renovation. 



If, with the extension, there is no open spatial connection (i.e. there are separating parts such as walls and doors), for the extended
building sections evidence of achieving a KfW Efficiency House Standard for New-builds must be provided. The evidence for the KfW Efficiency House may in this event be provided separately for the added
building part and does not have to relate to the building as a whole. 
  

	7.	 The application must demonstrate the saving in primary and end energy requirements and the CO2 reduction in comparison to the original state (renovation) or the applicable minimum requirement level (new-build). The calculation of the saving derives
from the difference between the energy requirement calculation under the EnEV for the condition prior to renovation or the requirements figure for a comparable new-build under the valid provisions of the EnEV
and the calculated energy requirement figures for the planned project. The resulting CO2 emission is to be determined applying the values cited in the Section “Emissions factors”.

 Technical Minimum Requirements 

Required evidence and documents for a KfW Efficiency House 

Complete documentation of the documentation per § 4 ErEV incl. detailed Ü value calculations for the individual construction parts of the thermal
building shell and the existing/planned technical systems 
 Documentation of the calculation for the reference building 

All plans for the KfW Efficiency House (ground plans, views, sections, site plan) on the basis of which evidence for the primary energy requirement under the
EnEV was prepared; the thermal building shell taken as a basis must be marked 
 Other planning documents where relevant for the calculation (for example
thermal simulation of solar systems, evidence of the primary energy factor applied for remote heat, evidence of product-specific technical parameters, etc.) 

Confirmation by a specialist firm of the execution of the hydraulic balancing (only for hydraulically-driven water-fed
heat supply systems) 
 Ventilation concept 
 If for the
primary energy factor when using local/remote heat the Table value under DIN V 18599-1: 2011 is not applied, the primary energy factor must be calculated either under DIN V 18599 and confirmed by an
independent expert or determined under the AGFW Worksheet FW 309 and confirmed by a certified expert 
 If a heat bridge supplement DUWB < 0.10 W/(m2 • K) is applied, this is to be calculated or evidenced separately under the
rules of technology. The preparation of evidence of equivalence under DIN 4108-Supplement 2 is always required in the event of the use of the lump heat bridge correction factors of DUWB = 0.05 W/(m2 • K) for renovation. When using a heat bridge correction factor DUWB < 0.05 W/(m2 • K) heat bridges must be calculated in detail. 

For consideration of a ventilation system with heat recovery or reduced air renewal in the Efficiency House calculation airtightness measurements are required
for the relevant area. The measurement results are to be recorded in a measurement protocol. 
 Requirements of individual measures for the renovation of
existing buildings 
 Measures to improve energy efficiency in existing non-residential buildings satisfying the
following minimum requirements are eligible for subsidy. 
 Calculation of energy saving and CO2
reduction 
 For individual measures the anticipated saving in primary and end energy requirements and the associated CO2 reduction must be determined. The calculation may be made using building balancing under DIN 18599 or a tailored calculation on the basis of system or specific building part parameters
(efficiency, Ü figure), the project dimensioning (for example power consumption of old system/new system, building areas) and the operating conditions (for example run times, usage conditions). To calculate the primary energy saving and CO2 reduction the primary energy factors under EnEV and the CO2 emissions factors in Annex 1 shall be applied.

 Technical Minimum Requirements 
  

	 	•	 	 Requirement-based regulation of heating systems, for example a usage-based room-by-room regulation of the room temperature 


  

	 	•	 	 Components for realisation of a technical energy management system with the aim of energy saving through
efficient operation of the building (for example monitoring of system or area-based characteristics and energy consumption, incl. building control technology and the required automation and field elements) 



Required evidence to be safeguarded: 
  

	 	•	 	 Measurement, control and regulation concept 



 

	 	•	 	 For technical energy management: metering concept
