How Window Orientation Impacts Energy Use in Mandeville, Louisiana

Window orientation is not just an architect’s preference in Mandeville - it is a daily line item on your power bill.

Before ordering new units, it pays to think through each exposure in our climate, then match glass specs and shading to the actual loads each elevation sees.

Managing south-facing glass in St Tammany Parish

If you can add any shade anywhere, do it on the south. Exterior shading stops heat before it reaches the glass.

Treating the sunrise side in Mandeville

Managing the punishing afternoon sun in Mandeville

West windows bear the brunt of late-day low sun that penetrates deeply and lingers, driving up late afternoon and early evening loads.

West-facing units benefit from the most aggressive solar control you can get within code and aesthetic limits, along with quality spacers to tame edge heat.

If you can only invest in one side’s shading, pick the west and do it right with exterior elements.

The north side in Mandeville is your easiest design win

Even up north, humidity can create condensation on cold snaps, so select quality spacers and well-insulated frames.
