Description
The project concerns comprehensive thermomodernisation of the building of the Public Elementary School No. 2 in Olesno. The leading body of the school is Olesno Commune, the school has an average of 410 pupils in grades 1-8. It is a free-standing building, built in prefabricated technology in 1996. The building consists of 5 segments: A, B, C, D, E. Blocks A, D and E 3-storey, with basements - heated cellars. Blocks B and C 3-storey, no basement. Total area of the building is 9482 m2, volume 45300 m3. External walls prefabricated according to the Żerań system, insulated with 4 cm thick wool, steel structure roof, covered with tar paper, wooden/PVC windows, steel/wooden/aluminium external doors. The building is heated by two gas-fuelled boilers. Pumped water central heating system, insulated within the boiler room and ductwork. Installation not thermally insulated in heated rooms. Steel plate and tube radiators fitted with radiator valves, 50% with thermostatic heads removed. Fluorescent, incandescent and LED lighting fixtures are installed in the building, metal halide fixtures in the gymnasium - all in poor condition. Within the framework of the designed deep thermomodernisation, it is planned to insulate the ceiling, roof, ceiling over the entrance, walls in the ground, external walls, replacement of windows and doors, modernisation of the heating system and the hot water installation, including the installation of a heat pump and a gas boiler, execution of mechanical supply and exhaust ventilation. A PV panel system is envisaged to produce electricity for the building''s own energy purposes. A PV panel system with a total capacity of 49.68 kWp is planned. Replacement of lighting fixtures with new ones based on LED sources, installation of motion sensors and installation of a building energy management system (EMS) are planned. The effects of the project will be reinforced by an educational campaign on the environmental impact of the project.
Summary of project results
The project solved the problem of the low thermal insulation and the lack of airtightness of elements of the Public Primary School No. 2 building, the problem of a faulty central heating and hot water system: an outdated boiler with low efficiency and an outdated installation causing high heat losses, and the problem of energy-intensive heat sources. These problems resulted in a high negative impact of the building on the environment, e.g. in terms of CO2 emissions.
The project implemented the assumptions of the documents: EU-Directive 2010/31/EU on the energy performance of buildings, national energy efficiency laws in the scope of thermomodernization, and the local Low Emission Economy Plan for the Olesno commune
As part of the in-depth thermomodernization, the ceiling, flat roof, ceiling above the entrance, walls in the ground and the external walls were insulated. Furthermore, the replacement of windows and doors, modernization of heating system and DHW, including the installation of a heat pumps, gas boiler, mechanical supply-and-exhaust ventilation and energy management system. In addition, the application of a system of PV panels producing electricity for the building’s own purposes and the replacement of luminaires with new LEDs.
Investor and environmental supervision was also carried out.
The following climate change adaptation and mitigation measures were also implemented: construction of a pocket park next to the school building, purchasing flower pots combined with benches and planting plants according to phytoremediation principles, promotion of cycling as an alternative to cars - purchase of bicycle racks and their placement next to the school building (6 pcs.), promotion of electromobility by purchasing scooter racks (2 pcs.), increase of energy efficiency by replacing external lamp posts next to the school building (21 pcs.) together with poles. ), increasing energy efficiency by replacing outdoor lighting fixtures on the school building (21 fixtures) with poles, promoting a closed-loop economy by replacing conventional waste bins (outside the school) with outdoor waste sorters to separate different types of waste (6 bins); changing the surface of an impermeable sports field to a permeable surface (sand) with a beach volleyball net. The project has been completed as evidenced by the final acceptance protocols attached to the final report.
Activities related to Communication and Information were implemented, such as the organisation of 3 conferences (at the start of the investment, during the investment and at the end of the investment) together with the production of conference materials, installation of an information and commemorative board.
An educational campaign was carried out: the materials for the preparation of birdhouses were purchased, as well as the training of teachers who led special interest groups on energy efficiency, the theoretical part and the practical part consisting in the self-assembly of birdhouses and their hanging around the school. The salaries of the teachers leading the special interest group were paid.
The following activities were realised: Events concerning the exchange of knowledge and experience: Organisation of a study tour of the Partner''s representative to Poland - to exchange experiences and good practices - On 27-29.07.2023, as part of the partnership agreement with Vista Analyse AS, the partner''s representative Mr. Herman Ringadal made a 3-day study tour to Olesno. A delegate from the Project Partner, Vista Analyse from Oslo, took part in the project launch conference, moreover, he conducted workshops on energy efficiency and experiences in the field of thermomodernisation investments in Poland and the Partner''s country. Employees of Olesno Town Hall presented to Partner’s delegate the natural and landscape richness of the commune, including the protected areas. Mr. Ringdal familiarised himself with the building of the Public Primary School No. 2 in Olesno, the scope of work, the energy audit, and learned about a number of issues covered in the technical documentation. The Project Partner provided knowledge on technical considerations, regulations and good practices for thermomodernisation investments in the EEA fund countries. The Project Partner also provided support on how to prepare and conduct an educational campaign (methodology, tools, sustainability) - the partner''s experience was used to publish a brochure. The project partner wrote a report about the cooperation and implementation of the project and best practices in energy efficiency. Within the framework of this task, the salary expenses of the project partner''s staff were covered.
Comprehensive thermomodernization of the Public Elementary School No. 2 building in Olesno, with external wall insulation and roof insulation, drastically reduced energy consumption for heating and cooling purposes - making the building more energy efficient. The installation of a heat pumps reduced the old heating system''s consumption of fossil fuels, reducing greenhouse gas emissions. The installation of photovoltaic panels did the same, replacing grid electricity in a country where nearly half of electricity production comes from burning coal - an energy source that has a number of negative effects on both local air quality and health, as well as massive greenhouse gas emissions. Overall, the renovation of the school building and the installation of solar panels and a state-of-the-art heat pump have contributed to reducing the school''s energy consumption.

Saving final energy up to 88.03%, primary energy up to 80.68%, increasing the use of renewable energy up to 20.04%, and reducing CO2 emissions up to 76.68%.The effects of the project has been strengthened through the implementation of an educational campaign on the environmental impact of the project and the exchange of experience with the foreign partner.
The results of the project benefited 366 students; teachers of the Public Primary School No. 2 in Olesno, in particular 3 teachers who were trained in energy efficiency. The training covered the following topics: the biggest heat losses before investment measures, energy savings after thermo-modernisation, discussion of efficient and low-carbon heat sources, energy management system, energy-saving building lighting, etc. Trained teachers led interest circles for pupils, a theoretical part and a practical part where pupils made their own birdhouses. The comfort of all users of the school building has been improved thanks to extensive thermomodernisation. In addition, the inhabitants of the Olesno commune (approximately 17,000 people) benefited from improved air quality in the region.
