help with west facing windows
We are in the very beginning stages of building our new home. We found a house plan that we like a lot. The great room sticks out the front like a prow but with a 90 degree angle so that when you look at the house from the front it looks like it has a triangle attached to it. Each of the two walls are 15 feet and solid windows. On our lot one side would face south and the other would face west. We would put the fireplace on the west wall to help block out the sun. The house is 2 story so the eaves would not help block out any sun. We live in Eastern Washington so more cool than hot but summers can get extremely hot. My concern is that this room would get too hot in the summer or make our cooling costs unbearable. I've been researching windows that are supposed to block out heat. Do they work? Are they a lot more expensive? Should I mix the windows so the southern wall lets in heat in the winter? Or are we crazy to build a wall of windows to the west? Thanks in advance for advice.
