Skylights

THERMAL COMFORT | DIY Method

BASIX requires the following details about the skylights in the dwelling:

  • area of the skylight at roof level (including frame)
  • frame material and glass type
  • shading devices.

One skylight that has an area of less than 0.7m² may be omitted. Do not include tubed skylights.

BASIX assigns a number to each skylight; this number cannot be changed.

BASIX will provide you with feedback on the glazing design if your project does not pass Thermal comfort. To pass Thermal comfort, focus on these to lower the heating and/or cooling loads:

The heating load can be reduced by:

  • selecting a frame and glass type with a low U-value
  • using adjustable shading instead of fixed shading if shading selected.

The cooling score can be improved by:

  • selecting a frame and glass type with a low Solar Heat Gain Coefficient (SHGC)
  • selecting an external shading device.

Note: The glazing feedback is shared between windows, glazed doors and skylights. Changes in one section may impact on the feedback shown in other sections.
