This thesis presents an analysis of energy efficient residential windows in hot and humid climates .
To accomplish this analysis , the use of accurate simulation tools such as DOE -2 .1e is required , which
incorporates the results from the WINDOW -5 .2 simulation program to assess accurate fenestration
performance . The thesis also investigates the use of optimal glazing types , which , for future
applications , could be specified in the code to reduce annual net energy consumption to zero .
Results show that combinations of low -E and double pane , clear -glazed windows , which are
optimally shaded according to orientation are the best solution for lowering both annual energy
consumption and peak electricity loads . The study also concludes that the method used to model
fenestration in the simulation program plays an important role in accurately determining the
effectiveness of the glazing option used . In this particular study , the use of the WINDOW -5 .2 program
is highly recommended especially for high performance windows (i .e . , low -E glazing ) . Finally , a
discussion on the incorporation of super high performance windows (i .e . , super low -E , ultra low -E and
dynamic / switchable glazing ) into the IECC code concludes that these types of glazing strategies can
reduce annual net energy use of the window to zero .
Future work identified by this thesis includes a more extensive examination of the passive solar
potential of high performance fenestration , and an examination of the appropriate methods for
specifying these properties in future versions of the IECC code . This implies that future specifications
for fenestration in the IECC code could aim for zero net annual energy consumption levels from
residential fenestration . |
