Dear all I am trying to analyze with trnsys the
impact of ground floor insulation on energy demand for a 4500 m² retail store. As a first step, I defined the ground floor
as a boundary condition and I set a ground temperature for each month using à
program call phpp For the winter months I have fixe a ground
temperature boundary condition of about 16°C and 20°C for the summer month. This way of calculating the heating and
cooling demand is of course not very realistic. The temperature depend of the
type of insulation, les surfaces of the floor, the perimeter, the other cooling
or heating load and so. Does anyone know how I could simulate more
accurately this situation with and without insulation on ground floor? Best regards Vincent Pirnay |
