Energy Efficiency and CO2e Emissions Reduction: A Proposal for a Guesthouse in the region of Krušné hory

This thesis explores the potential for reducing greenhouse gas emissions, increasing energyself-sufficiency, and enhancing circular economy practices in a specific mountain guesthouse. The main objective was to propose and evaluate measures that contribute to lowering the facility's carbon footprint while also assessing their economic viability. The practical part of the thesis included a carbon footprint calculation, an analysis of two variants of a photovoltaic system with a capacity of 64.8 kWp (with and without battery storage), and an evaluation of the degree to which circular economy principles are applied using the 9R framework. Two hypotheses were tested: the return on investment in photovoltaics and the potential for emissions reduction. In addition, a research question concerning the main sources of CO₂ emissions in the facility was addressed. The results showed that the variant without battery storage achieves a return on investment within three years (with a subsidy) and can cover up to 37% of the facility’s annual electricity consumption. The proposed measures—including PV installation, improved waste separation, and operational optimization—can lead to a reduction in emissions of more than 20%, with waste generation identified as the largest source of emissions. The findings confirm that even a small accommodation business can effectively contribute to mitigating the impacts of climate change.
