Cheyenne Mayor Rick Kaysen says  recently completed project to improve the energy efficiency of  over 30 city owned buildings will help save the city money on it's utility bills, in addition to being good for the environment. Kaysen says the project focused on reducing electricity and natural gas consumption in city buildings, as well as ways to reduce gasoline and diesel consumption by city owned vehicles. Although the project cost $1.3 million, Kaysen says about $1.1 million of that cost was covered by federal money. Kaysen says the city is still calculating exactly how much the project will save in monthly utility bills, adding a variety of factors must be considered in determining the savings. The contractor for the efficiency upgrade was Long Building Technologies of Denver.
