My grandparents had a house with a large attached greenhouse. The greenhouse was cooled with very large evap cooler pads on one wall and a couple exhaust fans on the other wall. On dry summer days, the air from the greenhouse was directed into their house via an enclosed porch. The air from the greenhouse cooled everything down into the 70's. (In Arizona, with daytime temps outside in the 110F range +/- five degrees.)
On humid days, when evap cooling wasn't efficient enough to keep the house cool, they turned on the AC and directed the air from the greenhouse into a side yard -- which had the biggest, healthiest, brightest bouganvillea I've ever seen before or since. I think that bush really liked the cool humid air that was regularly directed its way.
