Can someone help me with my renderings? I am in 2015. I have phasing, but the rendering views Phase filter is set to None and Phase complete. 

At first the glass is rendering as a solid opaque object (for some reasone the top clearstory has no glass panels which is why light comes through). You will see the back wall is solid gray in one rendering, and light comes through the next after I changed the phase filter. 

However, the rendering is still very dark. Behind the camera is a large storefront wall that is bringing in no light. I've added artificial light fixtures, but it is still dark. 

What do I need to do to get daylight from the storefront wall behind the camera? The panel materials are glass. 

Also, it is taking 45 minutes to render a draft view, is that normal?

Thanks much!!

Make sure you have lots of lights for the interior with good materials and tweek the render after the fact with the 'Adjust Image' tools to play with the tones etc. See attached image.
