Passive cooling systems in livestock buildings towards energy saving: A critical review

Passive cooling systems have already applied with success in urban buildings resulting to energy conservation. This paper presents the most important techniques and systems, concerning passive cooling systems applied in livestock building mentioned in the literature, to date. Passive cooling systems designed for livestock buildings should take into consideration the particular needs of farm animals, with reference to environmental conditions, as well as the specific characteristics of building construction materials. This work focuses on the description of the construction principles of the most common passive cooling systems of farm buildings and to the energy savings due to them. Apart from the comparison of energy savings and effectiveness of each cooling system, some similar systems used in urban buildings, which could be adopted in livestock buildings are, also, described. This study is important as it can be helpful to constructors and producers, aiming to proceed with modern sustainable farming methods. (C) 2019 Elsevier B.V. All rights reserved.
