Natural light pours into the breakfast room through French doors that open out onto the screened porch just beyond. Designing interior rooms so they "borrow" light reduces the need to use electric lights. Like all of the added windows, the doors feature double-pane insulated glass with a low-E coating that lets visible light through but keeps out heat. This reduces the need for air-conditioning, which the couple prefers to leave switched off anyway. All windows and glass doors also have shades or shutters to reduce heat transfer.
