Virgo: Daily green

Today is a good one to replace old windows with double-glazing to cut your heat loss up to 20 percent. Consider buying windows made from low-emissivity glass with a transparent coating that allows sunlight to pass through while restricting conduction of thermal energy. This means less heat loss in the winter and heat gain in the summer. If you're watching your budget, opt for an adhesive insulating film that can be peeled off windows in the spring.
