Sorry, I know, TLDNR.... My partial list...
Safe room for intruders, storms, tornados, etc. good place for gun safe or wifes jewelry safe.possibly hidden safe room?
Extra large ceiling fans in two most used rooms. Den has remote ceiling fan & light combo. remote is installed next to MY recliner. My Bedroom ceiling fan and light combo, remote sits on my nightstand.
Consider a whole home vacuum system.
Four-way switch turns on a lamp from every doorway into den. When entering home in the dark, we turn on lights to enter room, cross the room, then turn off when leaving Room, say to go to bed.
Cool ply plywood or radiant barrier for shingles/roof decking.
Window screens on west side are tinted, reduces radiant heat gain through window.
Extra wide attic folding stairs.
Media filter on Air/heat unit & possibly a Fresh air intake(?)
install a float / kill switch on drip pan under condenser unit. When your drain plugs and overflows into the drip pan, a kill switch will shutoff the A/c unit rather than f/u your ceiling with water. Install blowout spout on a/c drain line to run chlorox or air to unplug line.
Media filter at unit.Small Fresh air intake line (?maybe).
Continuous soffit vents & ridge vents
House is built with garage to west side. Forms a slight barrier to
evening sun, easier to keep sun off living areas.
Gas everything!
Consider installing backup generator & transfer switch. If on nat gas, hookup to generator.
Have masons install anchors when bricking, for hurricane plywood unless plylox will work for all windows.
If you have a camper install 30/50 amp service to outlet on driveway or wherever camper is stored.
Exterior lighting, landscape lights, lamp post on street has one timer built in to switch at front door. Switch will work manually light standard switch or automatically on timer.
Privacy fence has sacrifice board (true 1X6 board) at bottom, keeps cedar or treated fence from rotting as fast, keeps from tearing up fence boards with weed eater.
Consider skin venting. Exterior walls
The concept of skin venting (passive convective cooling) is to vent the hot, moist attic air out through ridge vents at the top of the roof and replace it with dryer outside air from the outside of the home.. To do this you need an unobstructed path for the air to travel up the exterior wall to the attic and out the ridge vent. This movement of air will occur naturally. {{my note here... A small vent is used about a foot off the ground, it is the exact same size as a brick and replaces a brick every few feet around the entire perimeter of the home. }}
Creation of the air gap in brick installations is easy because the brick doesn't rest directly onto the wall. There's a space between the brick and the wall. We just need to ensure the brick gap is exposed to the crawl space usually where the vents are. There are even weep holes at the bottom of the wall to allow a place for water to drain out that collects on the back side of the brick. This installation process has been the same for a very long time.
Once the air gap behind the brick is tied into the open space of the attic eve the air will flow freely from the bottom or underside of the house up the exterior wall and into the attic and out the ridge vent. Creation of the air gap in siding installation requires the use of furring strips to pull the siding away from the wall so there is an air gap. When combined with proper eve and ridge venting this skin venting process can have the same effect of sitting under a fan on a hot summer day.]
