Windows in the Cayman Islands
I'm beginning plans to build a house in the Cayman islands. For those not familiar, Cayman is basically south of Cuba and West of Jamaica. In my current house, 1k per month in electricity isn't crazy high so energy efficiency is obviously a priority. I'm curious of thoughts on windows in that regard.
I'm planning to have Bahamas shutters on most windows and others will be behind a 7 foot wide screen in porch (so obviously shaded). So between the Bahamas shutters and shade from the patio they won't have tons of direct sun on them.
Other windows will get direct light and on those I'll be getting the most efficient windows available and impact rated. For others that are behind Bahamas shutters and are shaded, I'm curious what ratings I should be looking at for efficiency. If double/triple pane windows with gas insulation will still offer good efficiency advantages on the shuttered/shaded windows I'll go all out on those as well, but at the same time I don't want to waste money on that if there isn't much benefit with windows with Bahamas shutters, etc.
Any thoughts? I've tried to attach an image to give the idea for those not familiar with these shutters
