Summary of the main modelling parameters.

TT, ma, and ρ are, respectively, the target inside air temperature, the mass of one animal, the sensible heat flow per animal mass unit and the density of animals in the farm (values are from [24]). L, ℓ, h, , and CF are respectively the farm’s length, width and height, the maximum installed power for heating, the ventilation power rate and total thermal capacity, see Eq 2, of the farm. The last column corresponds to reference outputs in standard conditions that are necessary to parameterize power supply simulations. Eref is the farm’s standard annual energy requirement per unit area, computed from weather data of outside air temperature, see Fig 2. BPV and BW are scale factors respectively for PV and wind power allowing evaluating the ground surface needed to produce Eref. H/Eref is the fraction of energy dedicated to heating over the year.
