N2 - This study investigated the energy performance of advanced glazing
in typical Danish commercial and residential buildings. We used
the tsbi3 hour-by-hour building energy simulation program to
analyze the demand for heating and/or cooling and peak load of the
heating/cooling system as a function of glazing/frame type, size
and orientation. The glazing area of the window was varied for
each facade corresponding to 0%, 15%, 30% and 50% of the area of
the facade. As climatic data we used the Danish Test Reference
Year for Copenha gen. Cooling, especially in residential
buildings, is not common due to the temperate climate.Two types of
glazing were used: Aerogel (U-value 0.6 W/m2K, solar-transmission
0.76) and Low-E double pane (U-value 1.85 W/m2K,
solar-transmission 0.73). As frames we used a traditional frame
(U-value 2.2-2.4 W/m2K) and a "super-insulated"-frame (U-value 1.5
W/m2K). Results from the models with Aerogel-glazing were compared
to results from the models with Low-E glazing. The general result
was that a change in glazing from Low-E to Aerogel would cause a
saving in the total energy-demand.Apart from the energy-savings a
change from Low-E to Aerogel-glazing will have a positive impact
on the indoor climate as the inside surface-temperature of the
glazing increases due to the lower U-value. The increase in
glazing-temperature reduces radiation-asymmetry during winter-time.
