Abstract
A two-node model of a room has been implemented in a computer
program, WinSim, de-veloped for evaluation of thermal window
performance in new buildings and in case of ret-rofitting. The
program calculates the annual heating demand and the number of
hours with indoor temperatures higher than a user defined limit as
a measure of the indoor thermal comfort level. 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 ob-tained 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 cal-culated annual heating demand and energy savings
due to window exchange, and also the calculated indoor thermal
comfort level is in the same range. Based on the limited examples
used for the comparison it can be concluded that WinSim is well
suited for a fast and realis-tic evaluation of thermal window
performance.
