Greenhouse windows are meant to create a warm and humid atmosphere within the window space. On hot summer days, however, the heat from the greenhouse can spread throughout the rest of the room. In order to combat this, shades are an invaluable part of your kitchen design. Lowering the shades in the morning will make sure that any heat created during the day will say in the window area and not in your home. So that you still get your natural light, you can tilt your blinds up rather than down to let the heat escape slowly.
