You can input your location and try different times of the year to see what your sun exposure would be.

You forgot to mention location in your original post. I'm in Canada, and it's the best exposure in my opinion, but we rarely hit 25C in my city. If you're in Texas, I would never chose that lot.

Thanks for the sun calculator. I woll need to get a more exact location to input for the lot. I live in Central Ohio so we do have some 90 degree days in the summer.

Does Central Ohio get a lot of snow? It's great having an exposure that lets the sun shine on the driveway all day if you do, to help melt anything left after plowing/shoveling. I don't have that now and I miss it.

Agree with paraveina if you're in an area that gets snow. In our last home with had a NW exposure and loved that we could be inside relaxing while the sun took care of our drive and walkways...our neighbors hated us when they were out there chipping at ice and brushing away drifted snow! We had decent sun in the back of our house, but that was without a covered patio, which I think would have made it dark. We're building a house with due north to the back, and southern exposure on the front b/c we found it so beneficial. It's all a matter of personal preference, influenced by where you live, I suppose.

The front of my home faces NW and because of the mature shrubs planted by the original owner and also the way the room is arranged--I don't have to have any blinds, etc on my LR windows. Only during the few weeks around June 21 does any sun at all come in the front windows. Of course it is still hotter outside on that side of the house than on the SE side, but the room is fine. Maybe putting your covered patio on the north (right) back corner of the house would protect it from the summer heat.

The best advice is to check solar charts for your latitude. Keep in mind that in the summer the sun rises north of east and sets north of west. In the winter, however, the sun rises south of east and set south of west.

The other issue you may want to check into is the line of the 100-year flood plain for the drainage area which shows to just touch your property line. If you are financing your new home, your bank will require mandatory flood insurance if your home will be in the 100-year flood plain.

Thank you, everyone...I'm taking note of all of your replies! Virgil, thank you for pointing out the 100 year flood plain line..we did notice that and need to check into flood insurance.

Anyone else have comments or experience with a home with Northwest exposure on the back windows and patio of a house?

Here's a great thread for you to read. http://ths.gardenweb.com/discussions/2432501/opinions-please-best-direction-for-house-to-face

It's really about your preference and most important, your location. In OH, consider that during the winter, you may want to use the southern sun to help heat. During the peak of summer, you may want shielded from the brutal NW sun.
