Analysis of improved fenestration for code-compliant residential buildings in hot and humid climates

by Mukhopadhyay, Jaya

Abstract (Summary)
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.
