“…Preliminary results for an EU project (2020-2024) called Res4Live (Res4Live.eu), included in Horizon 2020, have been reported (Faes et al 2021). The aim of Res4Live is to develop an energy model for livestock buildings for pigs as a tool to reduce the GHG contribution of European agriculture.…”

“…The project Res4live has developed a preliminary quasi steady-state energy model for livestock buildings intended for pigs, encompassing energy use, humidity, and indoor temperatures (Faes et al 2021). The energy balance accounted for heat loads from the animals and heating, as well as heat losses due to building airtightness, transmission through the building envelope, and ventilation losses.…”

Swedish pig farming is facing two climatic challenges: minimizing greenhouse gases and adapting to warmer climates in confined livestock buildings. Climate change leads to more heat waves, causing pigs in confined buildings to endure heat stress more often and for longer periods. Heat stress not only affects the animals' welfare and health negatively, but it also implies a risk of economic losses for farmers, as heat stress can result in slower growth, impacts on reproduction and increased mortality. Pigs are particularly sensitive to heat because they do have few sweat glands. This introductory paper on the subject “Improving energy-efficiency and indoor climate of livestock buildings for pigs through passive and active adaptation measures” highlightsthe need for adaptation measures due to climate change. The main aim of this introductory paper is to provide a summary of current research and knowledge on the energy efficiency and indoor climate of livestock buildings for pigs, as well as the need for further research on pig buildings in Sweden. Many studies have evaluated potential adaptation measures to lower indoor temperatures and reduce heat stress in warmer climates. The most commonly implemented measures for cooling are increased airflow and air velocity, as well as evaporative cooling. The reviewed articles also indicated that insulation and mechanical ventilation are required in warmer climates to maintain an acceptable indoor climate. The main conclusions are that: (1) Heat stress for pigs will increase due to global warming, necessitating adaptation measures to reduce indoor temperatures in warmer climates. (2) Technical solutions are available to reduce indoor temperatures in warmer climates. However, studies on the investment costs and energy use of these solutions are lacking. (3) To reduce the environmental impact of livestock buildings intended for pigs, it is necessary to develop energy-saving solutions, improve management practices, and use non-fossil energy sources. (4) Computer simulations can be used as a tool to predict thermal climate and energy use in livestock buildings. (5) It is recommended to develop a common framework and use standardised functional units to enable comparison and simplify evaluation of results from different studies.

This study proposes a novel annual temperature regulation system for sow houses, integrating heat recovery and photovoltaic-thermal (PV/T) technology to optimize energy utilization efficiency and economic benefits. Mathematical models of key system components are developed and validated using published data, yielding a maximum error of 14.48%. A numerical simulation assesses the system's operating characteristics across different months, revealing the highest total energy consumption and output power in April and August, at 7,298.7 kW and 2.18×104 kW, respectively. Conversely, the lowest energy consumption and output power are observed in November and April, at 2,739.4 kW and 1.10×104 kW, respectively. The results indicate that the system's performance is significantly influenced by external environmental factors. Future research should investigate the system's performance and control strategies in various climatic regions across China, providing theoretical guidance for the application of solar energy and heat recovery in the environmental regulation of sow houses.
