Night ventilation can help a lot, with a massy shell.
My simulations using hourly weather data say smart ventilation can keep a
house near Phila comfortable for all but a few days a year, when a
water-filled earth tube can help. Using the earth tube too often heats up
the soil. A house still needs airtightness and a small AC for
dehumidification.
