“…To reduce energy consumption due to climate control, improve indoor climate conditions, and decrease the dependence of livestock systems on fossil fuels, new solutions have been studied in recent years, with a focus on passive solutions [16,17] or the implementation of renewable energy technologies, such as geothermal [18] and aerothermal [19] heat pumps, photovoltaic panels [20], and biogas-fed combined heat and power units (CHPs) [21]. Evaluating the effectiveness and the potential of these solutions is a challenging task, typically accomplished via experiments or numerical simulations, which are often performed using Building Energy Simulation (BES) models.…”

The need to improve the sustainability of intensive livestock farming has led to an increasing adoption of Building Energy Simulation (BES) models for livestock houses. However, a consolidated body of knowledge specifically dedicated to these models is lacking in literature. This gap represents a significant obstacle to their widespread application and scalability in research and industry. The aim of this work is to pave the way for scaling the adoption of BES models for livestock houses by providing a comprehensive analysis of their application, development, and validation. For this aim, a systematic review of 42 papers—selected from over 795 results from the initial database query—is carried out. The findings underscored a growing body of research that involves BES models for different purposes. However, a common approach in both model development and validation is still lacking. This issue could hinder their scalability as a standard practice, especially in industry, also considering the limitations of BES models highlighted in this work. This review could represent a solid background for future research since provides an up-to-date framework on BES models for livestock houses and identifies future research opportunities. Moreover, it contributes to increasing the reliability of BES models for livestock houses by providing some recommendations for their validation.

“…The research conducted in this respect was mainly concerned with the effect of PV installations on greenhouse roofs on plant growth, as well as the volume and quality of crop yields. The obtained results show several benefits of this solution [20,21,26,[35][36][37][38][39][40]. Greenhouse cultivation requires considerable amounts of energy to control the internal environment, which depending on the climate, is used in cooling, heating or lighting [41].…”

“…Most of the studies have been primarily concerned with the effect of photovoltaic installations on the volume and quality of production [3,39,40,42,43,[46][47][48], while only to a very limited extent considering economic aspects. Querikiol and Taboada [31] compared the economic efficiency of the use of solar energy and diesel oil to cover the demand for energy to irrigate agricultural crops in the Camotes Islands (Phillipines).…”

The public’s awareness of threats to the natural environment, as well as the hazard to human lives and health posed by the use of fossil fuels to generate energy has resulted in the growing interest in renewable energy sources, thus promoting attempts to reduce the dependency on conventional energy sources. Among the former, solar energy is one of the most promising. The aim of this study is to assess the macroeconomic efficiency of investments in photovoltaic installations to meet the demand for electricity of farms and agricultural production. Calculations were prepared for 48 variants comprising three farm types (dairy farms, field cropping farms, and mixed production farms), as well as 16 locations throughout Poland. The obtained results indicate high efficiency of electricity production using photovoltaic installations to cover the needs of farms in Poland. In macroeconomic accounting, NPV ranges from EUR 8200 to almost EUR 23,000, with the payback period depending on the farm type ranging from 4.3 up to 6 years, while the internal rate of return amounts to 21–32%. Increasing the scope of investments in photovoltaics (PV) to cover the electricity demand not only of the household, but also of the agricultural production leads to improved economic efficiency of energy production both in the macro- and microeconomic terms.

“…Researchers in different countries offer their solutions to the problem of how to make intensive pig farming more environmentally sound. These solutions include, among others, the manure nutrients management system based on the mass balance method [5][6][7][8], energysaving approaches [9,10] and intelligent technologies that would provide the automated process monitoring, data analysis and technological and managerial decision-making [11][12][13]. The life cycle assessment is a tool widely used in assessing the environmental performance of integrated systems, such as large-scale pig farms [14][15][16].…”

The current trend towards larger pig farms increases their profitability but might harm animal welfare and the environment. More efficient pig manure management is a way to address this challenge. Available manure handling and utilisation systems may feature from 8 to 50% nutrient loss to the environment. Therefore, the proper choice of technological solutions is of high priority. In regard, the study developed a methodology including calculation, analysis and modelling techniques for the accurate accounting of manure amount, its fractions and their nitrogen and phosphorus content for different processing technologies with due regard to the limiting factors of the farm and the end-product consumer requirements. The methodology was applied to justify the best suitable processing technology for a large-scale pig farm in the Leningrad Region with 17,800 heads of pigs and 54,750 t of pig manure per year. The selected technology included manure separation into fractions, aeration and secondary sedimentation of the liquid fraction and passive composting of the solid fraction. It demonstrated the total amount of nitrogen (N) and phosphorus (P) in the end-products of 278.94 t per year, with the 26% total nutrients loss on all technological stages, and specific capital and operating costs of USD 55.5 per ton of manure produced. The methodology was tested by comparing the calculated data and the data from previous surveys of 15 pig farms in Russia. The differences between the values were found from 0.9 to 12.5% in mass; 2.8 to 13.9% in N content and 1.7 to 9.9% in P content. The developed methodology supports planning the production of the manure-based end-products in a given amount and with target nutrient content, depending on different processing technological solutions, achieving both economic and environmental goals.
