Program for Energy Renewal of Buildings in

Public Sector 2014-2015

Program goals:



Fulfillment of requirements in accordance with Directive

2012/27/EU of European Parliament and Council from

October 25th 2012.



Country members of E

U

made a commitment, starting from

01st January 2014., to renew 3% of total floor area heated

and/or cooled buildings owned and used by central

government each year



_{In case when these commitments aren’t fulfilled EU}

commission can begin formal proceedings for violation of

Program goals for period 2014÷2015



_{To contract and completely renew 200 public sector}

buildings - approximately 420.000 m

2

_{of heated area}



_{To decrease energy consumption in refurbished buildings}

for 30

÷

60 % (approximately 150 kWh/m

2

_{per year)}



_{To decrease CO}

₂

_{emission for approximately 20.500 t per}

year



To start investments in the amount of about 400 mil. kunas



To start energy services market (ESCo

Basic settings and characteristics of the

program:



Energy Service Client (ESC)

orders and Energy Service Provider

(ESP)

provides energy services in order to improve the energy

performance



Energy efficiency measures include the following:

- Preparation of project documentation

-

Energy renovation of the building (construction works,

installation of equipment and materials)

- Monitoring and investment maintenance of all elements of

the building and installed equipment which were the subject

of energy renewal.



ESP invests and takes technical and economic risk

so ESC

does

not have any additional costs



ESC

is obliged to ensure payment of compensation to ESP

during the contract period



Payment of services is

based on verifiable savings (service

charge should be less than the savings)



Energy efficiency contract is not budgetary borrowing

for ESC



Saving of energy are proved with the Project

Steps of Program:

1. Sign in the building - ESC submit to Agency form owner with basic information about the building and gives approval to Agency to start the process

2. Energy audit - Agency is doing a preliminary analysis.

If there’s no energy certification, Agency orders the energy audit and certification of the building and / or project assignment.

These documents are financed by Environmental Protection and Energy Efficiency Fund in total amount, according to Agency-Fund agreement. 3. Analysis of profitability - Agency compares data from the energy audit with data from EMS, analyzes the cost-effectiveness and decides to launch a public procurement procedure

4. Tendering - Agency defines the conditions of competition and tender

documents, conducts a public procurement and chooses the best Offer using the economic criterias for evaluation.

5. Contracting - ESC, ESP and Agency conclude a Energy efficiency contract.

6. Design - ESP must prepare project documentation (Project), which must include all the elaborate measures intended to achieve

savings and must prove values from the Offer

7. Project Control - in case of the special rules ESP must get a positive

report on project

8. Project Verification - ESP submittes the Project and Project Control to Expert Commission provided by Agency. Expert Commission

verifies compliance of the Project with the applicable laws of the

Republic of Croatia and checks whether the project demonstrate values from the Offer. Expert Commission gives the Verification of

the project.

9. Building Act- if needed ESP provides act allowing the construction 10. Co-financing the Program - Fund gives 40% of eligible costs in

11. Crediting -ESP can get loans of commercial banks and CBRD in

accordance with their loan programs. CBRD has Program for

credits of energy renovation of public buildings with guarantees from Croatian Agency for SMEs and Investments

12. Renewal –ESP is required to do the work of energy renovation of

the building in accordance with the verified design. Agency supervises Works through the expert supervision selected by a public procurement. The costs of supervision settles ESP.

13. Works handover- the end of renewal - After the completion of

the energy reconstruction Agency orders the energy certificate. After the certificate is done and after the final report is signed by the supervising engineer, ESC, ESP and Agency sign a report and determine the end of renewal. This act confirms that the

refurbishment works are carried out in accordance with the Project and verifies conditions for cost reduction.

14. Monitoring and Savings control - From the date of the end of the

reconstruction begins savings period and begins ESC obligations to pay compensation according to the EE contract.

Throughout the whole period of the EE contract, ESP shall implement measures to monitor and to control savings (users

training, regular check-up of the savings, investment maintenance

elements of the building and installed equipment).

Any change in the use of the building (user behavior) does not

affect the obligation to pay compensation.

Any change in energy prices does not affect the calculation of savings and the amount of compensation.

The amount of compensation is adjusted with the inflation index

for the previous year, according to data from the Central Bureau of

15. Unrealized savings - For the duration of the Contract ESC

may challenge the savings, if so both ESP and Agency must be informed without delay. The notification must contain the necessary facts and evidence on which ESC believes that the

savings are not realized. Agency will then engage an

authorized person to determine causes for it.

In the case of failure to achieve guaranteed savings ESP is required to remove these deficiencies. If it fails to do so within a reasonable time ESC has the right to cancel / terminate the agreement.

CONCLUSION!

By implementation of this Program government will accomplish long-term benefits in systematic and rational governance of its assets without risks and expenses for renewal. Impact of savings will be even more prominent if/when cost for energy products increases in the future. Systematic monitoring of energy

consumption will result in more rational behavior of public sector concerning energy consumption, which will lower pressure on State

budget.
