Description
The aim of the project is to improve energy efficiency in the school building, while increasing the share of energy produced from renewable energy sources. The project also intends to increase the awareness of residents in the field of the need to reduce CO2 and the advantages of using renewable energy sources. The works will include the replacement of window and door fittings, and insulation external partitions of the building with vertical insulation of foundations and insulation of ceilings. It will be combined with the replacement of the central heating installation along with the boiler room where the old oil boilers will be replaced two gas boilers in a cascade with an air pump. Everything will be completed with the installation photovoltaic with a power of 49.95 kWP and comprehensive replacement of indoor lighting fittings.
Summary of project results
Mucharz Commune is one of the smaller communes in Małopolska. It is inhabited by over four thousand inhabitants. On 28% of the commune''s area there is a recently opened artificial reservoir called: "Mucharskie Lake". Thanks to this, our activities are focused on the development of local tourism. An important element in achieving these goals is caring for the environment, so that the Mucharz Commune is associated with a clean and friendly place. We have a lot to do. Wanting to be an example for residents, we intend to carry out a deep thermal modernization of all public facilities in order to reduce CO2 emissions while achieving high energy efficiency indicators of these buildings. The use of renewable energy sources is intended to promote a modern way of obtaining, for example, heat energy, which will also bring measurable economic benefits. The subject of the investment co-financed from the Financial Mechanism of the European Economic Area 2014-2021 was the thermal modernization of the Primary School named after Father St. John Paul II in Mucharz. This is a building from 1999. Most public facilities in the Commune were built many years ago from poor quality materials. The technical conditions did not require the buildings to be energy-efficient. Currently, after the introduction of a number of restrictions aimed at reducing air pollution, these buildings must be absolutely adapted to the applicable standards so that they can function and serve residents for many more years. Therefore, the Mucharz Commune commissioned an energy audit, which showed high heat transfer coefficients through building partitions, and consequently a high demand for heat to heat the building and water. As a result, the school had a high demand for energy. The lack of renewable energy sources and the outdated central heating furnace generated significant fixed costs and was the reason for increased CO2 emissions. Several variants of investment works presented in the audit clearly showed that only deep thermal modernization together with the use of renewable energy sources can result in the intended savings in energy demand in this building, which will bring measurable benefits for the environment. The thermal modernization of this school was to bring, in addition to a measurable ecological effect, an educational effect. It was to encourage both residents and other heads of communes/mayors to change heat sources to ecological ones together with the use of renewable energy sources. In addition, educational activities also involved students in order to significantly increase their ecological awareness, which may have a significant impact on their social attitude in the future.
In order to achieve the best possible material effect and obtain the most favorable price for the work performed, the scope of the investment was carried out within 5 signed contracts. The scope of works was based on the design documentation, which was prepared on the basis of an energy audit specifying the technical requirements for meeting the planned indicators. The specification of the subject of the order provided for the use of materials and technology that were not worse than those provided for in the technical documentation. The lack of comments in the final acceptance protocols guarantees the achievement of the indicators. The investment works included the replacement of window and door joinery, insulation of the building''s external partitions along with vertical insulation of the foundations and insulation of the ceilings. All this was combined with the replacement of the central heating system in the entire building, including the boiler room, in which the old oil boilers were replaced with two gas boilers in a cascade with air pumps. In order to balance the energy consumption, a photovoltaic installation with a capacity of 49.95 kWP was installed. In addition, all internal lighting fixtures were replaced with energy-saving LED fixtures. Throughout the project implementation period, in accordance with the assumptions of the Communication Plan, the Mucharz Commune successively implemented all planned activities. First, promotional and information materials (bags, notebooks, leaflets, roll-ups) were ordered and received, which were then used throughout the project implementation period at meetings and conferences. Two publications were commissioned in a local and national newspaper. The first in 2022 and the second in 2024, presenting the project assumptions, its implementation and promoting pro-ecological activities. The project website was also launched. Two conferences for mayors were held in 2022 and 2024. Both were held on the premises of the modernized school, thanks to which the mayors of the communes could watch the implementations live before and after. In the field of promoting ecological activities among young people, a competition was held for students of the 8th grade and grades I-III. The last element of the program were meetings with residents in November 2022, April 2024, September 2023, which aimed to encourage residents to replace old heat sources with new, pro-ecological ones. A commemorative plaque was also installed in accordance with the requirements.
As part of the project, the energy efficiency of the building was improved in terms of:
1. reduction of CO2 emissions by 137.4 t/year
2. production of energy from renewable sources - 102.94 MWh/year
3. primary energy savings - 560.78 MWh/year
As part of the investment, one school building was modernized. One oil-fired furnace was replaced with a gas furnace supported by 3 cascade-connected air pumps with a capacity of 43.4 KW each. In addition, a photovoltaic installation with a capacity of 49.95 kWp was installed. The entire system was connected with an energy management system. Mechanical ventilation with heat recovery was installed in the gym. Promotional and educational activities included a total of 9 social campaigns and two articles in the press.
