Abstract:The internal rearing environment of livestock houses has become an important issue in the last few years due to the rapid increase in meat consumption. As the number of days of heat waves increase continuously, problems caused by abnormal weather changes steadily occurred. Thus, the main goal of this study is to develop a technology that can automatically calculate heat stress for livestock by considering weather forecast data. Specifically, a web-based heat stress forecasting system for the evaluation of heat… Show more

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.

Recent climate change trends have leaded thermal and cold stress concerns in commercial broiler houses, significantly impacting the animal welfare, productivity, and energy efficiency of broiler farming. Consequently, conducting an energy load analysis is integral to reducing energy consumption and ensuring optimal conditions for livestock.This study developed a Building Energy Simulation (BES) model, validated to predict the internal environment and energy demands in broiler houses. To validate the BES model, field experiments were conducted in a commercial broiler house for data collection of both internal and external environmental conditions. The precision of BES model was evaluated using the Coefficient of Variation of Root Mean Square Error (Cv (RMSE)) and Normalized Mean Bias Error (NMBE), resulting in a Cv (RMSE) of 2.82% for air temperature and 2.72% for absolute humidity, and NMBE values of 2.26% and -1.42%, respectively. These results demonstrate the high accuracy of model, aligning with building energy model standards. The BES model, implemented in the field experiment broiler house, predicted a heating load that peaked at approximately 1893.23 MJ/hr, while the cooling load was anticipated to maximize at about 1627.61 MJ/hr. The cumulative total of the heating and cooling energy loads was estimated to be around 3,303,895 MJ. Results indicate the developed model could potentially improve energy efficiency in broiler houses and assess energy loads under various conditions.
