You’ve probably heard the warnings of higher heating bills this winter and the need to prepare your home — but you may not know how to go about it. The Iowa Energy Center at Iowa State University is offering a free booklet to help you out.

Energy Center spokeswoman Amy Swenson says the book is part of a series that helps you with your home. She says the home series books gives a lot of good instructions that you can do yourself, like caulking windows and adding insulation, that you don’t have to have a lot construction knowledge to be able to do. Swenson says the time you take to make the improvements will show a benefit on your energy bills. She says people have found anywhere from a 30 to 40 percent savings on utility bills.

Swenson says the book is called: “Home Tightening, Insulation and Ventilation.” She says you can get a copy of the book by calling 515-294-8819 or by going to the website at:www.energy.iastate.edu. Swenson says making sure your home is properly ventilated can protect your home from moisture damage year-round, reduce problems caused by ice dams on the roof during the winter and significantly cut summer cooling costs.
