Vents up near the top of the roof or the ceiling to let the hot air out. Vents down near the floor to let the cooler air in. If your house is up on post and pier, vents in a closet floor with a louvered closet door will allow airflow in from the cooler under house area.
Louver (jalousy) windows have 100% ventilation as opposed to the glass pane windows which typically only have 50%.
White roof, if it isn't already white, there's that 'sno-coat' roof paint. That will reduce the temperature by about thirty degrees or so on a hot day. Less heat to get in.
Big roof overhangs or a lanai all the way around. That keeps the sun off the walls of the house.
Cross ventilation, windows on opposite walls from each other when ever possible.
Maybe a trellis with a lilikoi growing on it on the sunny side of the house. That will create shade along with the lilikoi.
Photovoltaic or solar hot water panels on your house will help shade the roof as well as make electricity and hot water.
Put photovoltaic panels on the roof to run the air conditioner. On hot days when you want the A/C is when you'll have the sun on the solar panels to power it.
