Good afternoon,
I will need structural construction of the walls, doors, and windows for this building (If you have any drawings or sketches it would be of great help). It will take me around 4 days to finish the calculations and find the appropriate insulation thickness. I need to check/calculate current heat losses of the building, and then I have to apply few insulation thicknesses to find the right one that depends on the cost of material compared to the cost of energy per 1kW (The thickness of the insulation is usually between 5 and 10 cm). And then I can find the payback period. Also, I need to know the position of the building so I can find the outside project temperature for the winter season. The calculation process will be delivered in MS Office Word - first for uninsulated building and second for insulated building.
Sincerly,
Ilija Veljkovic
