Your house will not actually smile but you certainly will after you see your energy bills becoming lower and the amazing feeling you will get after discovering how easy it is to play a positive part for the environment while keeping extra money in your pocket.
Here are five changes you can make to go green:

1. Cotton Fiber Insulation: This product is made from recycled blue-jeans scraps; is soft and safe to handle and 100% recyclable.
   Safety perks include it being treated to resist fire, no formaldehyde or other chemical irritants and no itching or skin irritation.
   
2. Natural Linoleum is not only long lasting but also recyclable; no glue is required for the "click-in-place" installation.
   Safety features include asthma and allergy friendly and dry dusting prevents allergen accumulation.
   
3. Cool Metal Roofing saves approximately thirty to forty percent on cooling and energy costs and lasts two to three times longer than conventional shingle roofs.
   A perk is that it is resistant to hail, wind and fire.
   
4. Energy Efficient Windows are a fantastic way to reduce heat loss and cooling costs, especially the Energy Star compliant windows which greatly reduce energy bills from between 7 to 24 percent.
   An excellent safety perk if you are worried about kids playing sports or if you live in a busy neighborhood is that the laminated glass reduces outside noise and stays in place if broken.
   You will still be annoyed by those footballs or golf balls but at least the people inside the house will be safe from the minimal impact of the broken glass.
   
5. Finally, there is Mold Resistant Wallboard or gypsum wallboard with a moisture resistant core that reduces risk of mold and wasteful replacement.
   An excellent safety perk is that it helps to keep indoor air quality at a healthy level.
   

So even if you are not able to implement all of these changes at once, it is a good start to keep some of these options in mind.
Not only are you reducing your energy costs but keeping your family safe also.
