Along the way, we will note where hurricane-rated, impact-resistant, and moisture-resistant products change the picture in our coastal zone.

How to Model AC Savings From Windows

The Energy Modeling Process

How the energy model works, in plain language

Start with a quick inventory: count windows by orientation, measure rough sizes, and note shading from porches, trees, or awnings. When specs are unknown, a practical baseline is U 0.50 and SHGC 0.60 for legacy double panes, plus higher air infiltration. Good Gulf Coast packages for energy-efficient windows that reduce AC costs in Mandeville LA usually show U about 0.28 to 0.30 with SHGC about 0.25 to 0.30, tuned by facade. Use SHGC and facade solar data to estimate heat gain across each glazed area, with east and west driving the worst spikes. Estimate conductive gain with U-factor, delta-T, and area, which matters on long, hot afternoons and those muggy nights. Do not forget infiltration, since new units with better weatherstripping cut convective loads that older windows leak. Translate total BTUs into kWh with your AC’s EER or SEER, and multiply by your utility rate, which yields an annual savings number with clear assumptions behind it.

Typical AC Savings in Mandeville

Typical savings ranges for our climate

Expect around 10 to 20 percent less AC energy use when upgrading to modern low-E units, especially if afternoon sun loads dominate. Single rooms with large east or west exposures can feel like different spaces post-upgrade, since peak solar gains are where SHGC does the most work. With a high-SEER system, you still capture the same load reduction, though total dollars saved drop slightly because the starting AC use is lower.

Window Selection for Energy Efficiency

Match the unit to the exposure and the moisture

Keep SHGC tight on east and west, where glare and heat spike, and allow moderate SHGC on south if eaves shade midday sun. Frame-wise, vinyl windows that resist moisture and mold in St Tammany Parish are solid when well built, and fiberglass brings top-tier thermal stability.
