Abstract
A two-node model of a room has been implemented in a computer
program, WinSim, devel-oped for evaluation of thermal performance
of windows in new buildings and in case of retro-fitting. The
program calculates the annual heating demand and the number of
hours with in-door temperatures higher than a user defined limit.
WinSim is characterised by the limited amount of required input
data. Guide-lines for calculation of the effective thermal
capacity of the room is given, and results obtained with WinSim
have been compared to results from an advanced building simulation
program. Good agreement has been found between the two programs
with respect to calculated annual heating demand and energy
savings due to win-dow exchange, and also the calculated number of
hours with overtemperature is similar. Based on the limited
examples used for the comparison it can be concluded that WinSim
is well suited for a quick but realistic evaluation of thermal
performance of windows.
