ANALYSIS OF THE EFFECTS OF THE ROOFING DESIGN ON HEAT STRESS IN DAIRY COW HOUSING
AbstractA simulation model determining the heat flow exchange between housed animals and the roofing was developed considering various relevant factors: constructive materials, slope, height, orientation, latitude, external air temperature, solar load, animal position. Results show that the most important factor to reduce heat load is the insulation. For non-insulated roofing the slope and the orientation are the most relevant factors. Considering the total exchanged energy, the non insulated roof has a good nocturnal global behaviour.
