Albertville - France
Intracting is a process that enhances energy performance by collecting savings from auto financing measures for new energy savings. This practice presents itself as a municipal fund implemented by financial services, which grants loans to technical services for energy savings projects.
These funds are actived by savings and applied to new measures which then generate their own energy savings. These funds grow over the years generating new resources due the multiplifying effect and reduction of energy spendings that they generate.
Fund of Energy Savings and Renewables: Litoměřice - Czech Republic
The Fund was established by a Local Authority, the City of Litoměřice, in 2014 as a part of its internal budget. The Fund aims to reduce long-term operating energy costs of the Local Authority and assets it runs, such as schools, museums and libraries by implementing energy efficient measures and installing renewable energy sources with a minimum impact on the municipal budget. Each year net savings are calculated and distributed according to an agreed formula among various levels of the Local Authority. Savings are reinvested in new sustainable energy projects.

Yearly energy consumption was reduced by 5.952 MWh, energy costs by 446.000 EUR, maintenance costs by 28.500 EUR and CO2 emissions by 1.305 tonnes.
Municipality of Radlje ob Dravi - Slovenia
Energy performance contracting in the form of public private partnership model is well known to be used in public and private buildings. To be used in the building that is owned both by public and private partner is technically possible but needs more coordination and understanding for all partners. Municipality of Radlje ob Dravi has decided to use EPC model in such building. Municipal administration, with the help of energy agency, was able to manage and coordinate the project's implementation and they have successfully realized it. They have newly renovated building in the town centre used for library, shop and caffe.

BAOBAP’s ambition is to accelerate the renovation rate and improve the energy saving gains of public building renovations in small and mid-size municipalities through the deployment of multiple regional units of BAOBAP’s renovation support service.BAOBAP mobilises the existing network of support services established in Auvergne rhône alpes and Occitanie in order to develop local units of support services and Regional Renovation Support Packages
Creation of local solar energy communities on municipal buildings in Valladolid
The City Council of Valladolid has granted a concession to install solar panels on municipal rooftops and create local energy communities. These cooperatives will provide shared solar selfconsumption to households within 2,000 meters, benefiting around 390 families. The initiative supports the city’s energy transition, prioritises lower-income households, and offers free energy advisory services. Through the concession model, the awarded company covers all investment and maintenance costs in exchange for the use of municipal rooftops. The City Council receives compensation in kind, amounting to about 10.35% of the energy generated. The concession lasts 15 years, with the option of two additional five-year extensions.

The city of Bergamo has signed a 10-year EPC contract involving approximately 160 public buildings in different actions: energy service, energy refurbishment and maintenance. The contract foresees guaranteed reduction goals in energy consumption The contract foresees guranteed reduction in energy consumption following focused refurbishments the financial plan includes cofinancement through the national incentive scheme "Conto Termico 2.0". During the preparatory phases the municipality was supported by AESS which, as a technical advisor, helped gathering and organizing data, auditing buildings and assessing technical systems. The technical advisor is a secondary actor that facilitates the process through its key steps.
Energy Refurbishment of 24 Public Buildings in the City of Maribor, Slovenia
In 2018, the Municipality of Maribor selected 24 energy-inefficient public buildings for a comprehensive energy renovation. Energy-efficient measures and the introduction of renewable energy sources were implemented in primary schools, kindergartens, administrative buildings, the ice (skate) hall and the sports hall. They included insulation of envelopes, new windows and doors, insulation of attics and basements, renovation of heating systems, instalments of thermostatic valves, new LED interior lighting and introduced energy management. Special attention was paid to user involvement, information and educational activities to influence the good climate and energy behaviour.
Energy Performance Contracting in Litoměřice
The Energy Performance Contracting (EPC) project modernised 11 municipal buildings, including schools, sports facilities, cultural venues and municipal office buildings. Prepared in 2014–2015, the project was designed to enable the comprehensive renovation of a larger portfolio of public buildings without placing a significant burden on the municipal budget. By using the EPC model, the municipality was able to implement energy efficiency measures with guaranteed savings, reducing financial risk while improving building performance. The measures focused primarily on heat savings through the replacement and optimisation of heat sources and control systems. Additional improvements included the installation of energy-efficient lighting and water-saving technologies. In energy-intensive facilities, such as the municipal swimming pool and winter stadium, specialised upgrades were introduced, including modernisation of pool water filtration systems and stadium technologies. The project was delivered in close cooperation between the municipality, energy specialists, the relevant municipal organisations and the ESCO partner, ensuring professional implementation, performance monitoring and verified energy savings.
Blending capital to finance solar PV panels providing energy to public buildings – Tipperary County Council
The programme (2014-2015) aimed to install just under 200 kW of rooftop solar PV across 9 local authority buildings (civic offices, fire stations, libraries, leisure centre and machinery yard). Tipperary Energy Agency led feasibility, detailed design, public procurement and project management, working with Tipperary County Council, contractors and SEAI. The programme was reported to have increased national PV capacity by 44% in 2014 (project estimate).
City-led Support for Renewable Energy and Energy Sharing in Litoměřice
The city implemented energy efficiency and renewable energy projects and subsequently verified the net energy savings. These savings were then converted into monetary savings and transferred into a dedicated Revolving Energy Savings Fund. The savings were divided into four parts: - returned to the municipal budget; - reinvested into the fund itself. - allocated to the municipal organisations and departments where the projects were implemented (creating direct motivation); - and a smaller share was used as a reward for staff involved in project preparation and delivery. A key feature of the Litoměřice model was that the fund was designed to be as independent as possible from the municipal budget, with new measures financed mainly from previously achieved savings. In practice, building operators were able to keep a significant share of savings (e.g. around 30%) for their own use, strengthening ownership and engagement. The accumulated resources were then used to prepare further projects, including energy assessments, technical and structural assessments, feasibility work, and other preparatory activities, ensuring a continuous pipeline of well-designed measures.
