“…Secondly, a Chinese scholar introduced an innovative ventilation system combining a cooling pad and ground channel that can provide ample fresh and cooling air to meet the demands of large-scale pig farms [51]. To address the varying thermal comfort requirements of sows and piglets in the lactating house, the utilization of water-cooled pads can effectively resolve this issue through localized cooling [52]. However, it is important to consider the energy consumption associated with cooling operations when implementing these methods in farm facilities.…”

The carbon footprint of pork production is a pressing concern due to the industry’s significant greenhouse gas emissions. It is crucial to achieve low-carbon development and carbon neutrality in pork production. Thus, this paper reviewed the recent studies about various sources of carbon emissions throughout the current pork production chain; feed production, processing, and manure management are the major sources of carbon emissions. The carbon footprint of the pork production chain varies from 0.6 to 6.75 kg CO2e·kg−1 pig live weight, and the carbon footprint of 1 kg of pork cuts is equivalent to 2.25 to 4.52 kg CO2e. A large reduction in carbon emissions could be achieved simultaneously if combining strategies of reducing transportation distances, optimizing farmland management, minimizing chemical fertilizer usage, promoting organic farming, increasing renewable energy adoption, and improving production efficiency. In summary, these mitigation strategies could effectively decrease carbon emissions by 6.5% to 50% in each sector. Therefore, a proper combination of mitigation strategies is essential to alleviate greenhouse gas emissions without sacrificing pork supply.

“…Air temperature was measured by DS18B20 temperature sensors [59]. Both these sensors are commonly used in different scientific research [60][61][62] mainly because of the easy connection of many measuring points into one bus, good accuracy and low cost [63]. The same sensors were also used to measure floor temperature.…”

Modern buildings with new heating, ventilation and air conditioning (HVAC) systems offer possibility to fit parameters of the indoor environment to the occupants’ requirements. The present paper describes the results of measurements performed in an office room in the first Polish passive commercial office building during four months of normal operation. They were used to calculate parameters describing thermal comfort: vertical air temperature profile, floor surface temperature, predicted mean vote (PMV) and predicted percent of dissatisfied (PPD). Obtained results confirmed good thermal conditions in the analysed room. The average temperature of the floor’s surface varied from 20.6 °C to 26.2 °C. The average vertical air temperature, calculated for working days, was from 22.5 °C to 23.1 °C. The temperature difference between the floor and 5 cm below the ceiling was from −0.9 °C to 6.3 °C. The PMV index varied from 0.52 to 1.50 indicating ‘slightly warm’ sensation, in spite of ‘neutral’ reported by employees. Also measured cooling and heating energy consumption was presented. The performed measurements confirmed the ability of thermally activated building system (TABS) to keep good thermal conditions.

“…Maintaining appropriate temperature and humidity levels is paramount for ensuring the normal growth and development of pigs [1][2][3]. When the ambient temperature exceeds the thermoneutral zone, pigs adjust their heat production and energy intake to mitigate the effects of heat stress [4][5][6]. Elevated ambient temperatures can significantly increase the incidence and mortality rates among pigs, compromise animal welfare, and result in substantial economic losses [7][8][9][10].…”

Efficiently managing temperature and humidity in a pig house is crucial for enhancing animal welfare. This research endeavors to develop an intelligent temperature and humidity control system grounded in a three-way decision and clustering algorithm. To establish and validate the effectiveness of this intelligent system, experiments were conducted to compare its performance against a naturally ventilated pig house without any control system. Additionally, comparisons were made with a threshold-based control system to evaluate the duration of temperature anomalies. The experimental findings demonstrate a substantial improvement in temperature regulation within the experimental pig house. Over a 24 h period, the minimum temperature increased by 4 °C, while the maximum temperature decreased by 8 °C, approaching the desired range. Moreover, the average air humidity decreased from 73.4% to 68.2%. In summary, this study presents a precision-driven intelligent control strategy for optimizing temperature and humidity management in pig housing facilities.
