The main purpose of this report is
investigations on ventilated windows.
The article primarily dealing with analysis
of window energy efficient design
and its performance in cold and warm
period of year. Analysis on seven different
cases has been carried out to identify
the important contributors to the total
energy gains and losses. These are
then optimised with best solutions to
get as good results as possible in energy
balance calculations. Energy balance
calculations are second part of investigations.
By implementation of this
method and simulation programs, results
obtained later can be compared.
Problems, concerning panes configuration,
location of low-E coating and position
and type of shading device, can
be solved afterwards. The last part of
the project includes Simple calculation
method applied to a real building in order
to find most suitable option in aspect
of energy balance during year.
