Abstract:
... One of the main concerns regarding intensive broiler production is the high use of energy for climate control. An improved design of broiler house envelopes could decrease this energy consumption. Current evaluation methods only consider the delivered energy, which is misleading because it does not consider the entire energy supply chain. By contrast, primary energy encompasses all forms of direct ...
