Recommendations for ventilation systems, approaches?

Good a/c split systems incorporate what is commonly called an economizer that uses the outside air instead of the compressor to heat/cool if the climate supports it. Your location does [low humidity/warm days and cool nights]. At night you should be using outside air to maintain inside temps until the following morning when it warms up enough to require the compressor. If you have a swimming pool, it can be used as a heat sink to cool the house during the day and warm it at night or use the house a/c to warm the pool.
There are also standalone solar a/c that boost the capacity of the grid tied unit. Your location gets lots of sun and might benefit from this.  http://www.hotspotenergy.com/solar-air-conditioner/

The outside air can be run through an air-air heat exchanger or piped in directly depending on your preference.
