My home is like that. My backyard, kitchen, dining room, great room and MB are facing southwest. Despite double glazed windows, they are hotter than the rooms facing northeast in summer. But the rooms you hang around most are bright and filled with CA sunshine. I don't want to live in a dark cave. Also Santa Ana wind blows from northeast to southwest and I don't want the wind to blow right at my sliding door and large great room windows. Also garage is slightly cooler, because it's facing northeast. The room above garage does get hotter than other rooms. It'll be better if the house has a CA room next to the living room, because the house will still be bright but slightly cooler.
