The paper presents the calculus program expert kind
“WINDOW-WALL” for the modelling and simulation of
the thermal transfer through structures with complex
formation for the heat flow and thermal resistance, for
windows made off wood, PVC, metal, aluminum. The
program also takes into account the interaction between
the window and the wall where is fitted in.
This expert system of analysis for windows and doors
permits the analyze for various constructional solutions.
The purpose is the optimization of its structures for a
better energy economics.
The numerical calculus and results are presented for the
homologation of the calculus program “RAMA”/”
FRAMEWORK” made in accordance to the methodology
from ISO 10077/2:2003  for examples from the figure
D 10 and D 1, annex F.
The methodology belonging to the norm refers to the
calculus of the thermal transmission coefficients and to
the adiabatic conditions at the contact between the
window framework and the wall in which it is fitted.
