Decorate with pale colors on walls, ceilings and floors. Soft tones reflect more light, so you can use lower wattage bulbs and delay turning on lights until later in the day. Using high-gloss paint can help as well.
If your home renovation requires new walls, you may want to consider using metal studs. They have many advantages in a basement area, where moisture and insects can be a problem. Metal studs are easy to assemble, and you can pre-cut several at once with a carborundum blade on a power saw. Then, they quickly fasten together with self tapping-screws. Metal studs are lightweight, fireproof, and recyclable.
