Darkness and light are themes that run heavily through Van Gogh's work. Darkness and lightweight reflected his wish create beauty, his feelings of inadequacy, and his desire to touch the souls of men. For instance, Starry Night draws the viewer to the painting of a sleeping village with its swirls of light as well as rich evening sky. A tighter built home means less outside air infiltrating in the home, which in turn means less oxygen to use for combustion within the furnace. As the furnace burns fuel and oxygen for combustion, it "eats up" the nearby air, which has to be "made up" with fresh air. If air cannot type in the home as quickly anymore, this could cause serious issues. As the surrounding air can be used for combustion, and not substituted for fresh air, a bad pressure in the space can take place. This could create combustion trouble for the furnace, plus consume fresh air for any person inside home. The event takes place in English Bay at 10:00 PDT on four nights, beginning over a Wednesday and ending on a Saturday, over the bi weekly period during July and August. Each of the four performances have at least a three-day separation for preparation for the next competitor. Three companies representing their countries perform a twenty-five minute firework display set to music. A grand finale is performed on the last day by all the competitors.
