“…Energy use is one of the contributing sectors to CO2 emissions. Until 2011, fossil energy consumed up to 96.21 percent of the total national energy (Nawalany et al, 2023). Energy issues are also accompanied by the energy crisis and the commitment of the Government of Indonesia through Presidential Regulation No.…”

The livestock sector has significant potential to contribute to methane emissions, which are the second largest after CO2, accounting for 13% of total emissions. One solution to control methane emissions is the use of biogas reactors. This study aims to assess the financial aspects of biogas production from livestock waste to meet household energy needs and to determine its financial feasibility. The research employs a qualitative approach that emphasizes flexibility, direct interaction with research subjects, and sensitive interpretation of data context. Data collection was conducted through a literature review by examining and analyzing literature related to the research topic. The literature study results indicate that constructing biogas reactors using cow dung has viable potential for development, especially as a replacement for LPG. However, replacing wood fuel depends highly on the local price of firewood. This study recommends that, for the development of biogas from cattle farm waste to replace firewood, interest subsidies or other assistance are needed to make the development feasible. Additionally, to encourage public interest in developing biogas reactors for cattle farm waste, financial incentives in the form of interest subsidies through program loans are necessary. Developing biogas reactors from cattle farm waste for household energy needs is economically viable, especially as a substitute for LPG, but requires additional support such as interest subsidies to replace firewood. Financial incentives are essential to attract public interest in developing these biogas reactors.

The growth in population increases greenhouse gas (GHG) emissions into the environment. High GHG emissions are attributed to meat production, due to its high energy demand. The largest carbon footprint in the production of poultry meat is generated by combustion. This paper deals with the problem of greenhouse gas emissions (total dust, CO, CO2, NOx, SOx and benzo(a)pyrene) resulting from the generation of energy for heating broiler houses located in different locations in Europe. The study includes continuous measurements of selected microclimate parameters: temperature and relative humidity inside and outside the building, floor temperature, wind speed and direction, and solar radiation intensity. Validation and calibration of the model, emission calculations, and analysis of the obtained results were conducted. Eighteen design variants were assumed, differentiated by the heating fuel used (hard coal, fuel oil, gaseous fuels), material and construction solutions for the floor and the location of the facility. The analysis showed that CO2 emissions for a facility located in northern Europe are 123,153 kg higher compared to the same building located in southern Europe. In addition, increasing the floor’s thermal resistance by 3.69 m2·K·W−1 reduced harmful gas emissions by an average of 5.7% for each of the locations analysed.

The article presents the results of research on the impact of material and construction solutions on energy demand and greenhouse gas emissions. Field research was conducted in an existing free-standing greenhouse located in southern Poland. The research period covered the entire calendar year. The measurement data were used in the next step to validate the computational model using the numerical method of elementary balances. The data distribution was also analyzed in terms of basic statistics. The validated and verified model was used in the further part of the analysis to conduct computer simulations for three variants, differing in terms of material and construction solutions. The variants included: no foundation insulation, extruded polystyrene (XPS) insulation and the use of single-chamber polycarbonate panels with thermal insulation of the foundations. The obtained results showed a high agreement between theoretical and real data (85–89% for the coefficient of determination (R2) and 84–88% for the GOF method). In the case of variant 1, which in terms of material and construction solutions corresponded to the actual construction of the greenhouse, it was found that the annual energy demand for heating purposes amounted to 153,234 kWh/year. In variant 2, in which additional thermal insulation relative to the zero state was used, the energy demand for heating purposes was lower and amounted to 147,704 kWh/year. The lowest heat load was characteristic of variant 3, in which 116,294 kWh/year was required to cover heating needs. The variant with polycarbonate and foundation insulation brought energy savings of 24% and a reduction of CO2 emissions by 24%. In addition, replacing fuel from hard coal with natural gas brought significant benefits, reducing pollutant emissions by 51%. The paper is a new approach to the use of the mentioned numerical method for the assessment of gaseous pollutant emissions in this type of building based on numerical simulations of energy consumption.
