Energy Loads Calculation of Standard Design Models for Laying Hens using a BES technique and Development of Regression model for Energy Loads Prediction

Abstract

Energy loads for layer standard design models presented by the Ministry of Agriculture, Food and Rural Affairs (2019) were evaluated. The BES technique was adopted to calculate periodic heating and cooling loads of layer houses by region, building scale, number of heads, and wall and roof insulation conditions. The designed BES model considered real-time latent heat generation from layers and variations in ventilation rate according to indoor and outdoor environmental conditions. Variations of periodic heating loads for layer houses were relatively higher than periodic cooling loads according to wall and roof thickness changes shown in a previous study. BES computed periodic heating and cooling loads under various conditions could be utilized to establish standard designs for layer houses, especially regarding physical insulation characteristics based on considerations of energy efficiency and cost. Regression equations for predicting heating and cooling loads of layer houses were derived (adjusted r-square values were 0.93 and 0.86, respectively) to facilitate the development of energy load self-assessment tools for layer farmers
