If you're interested in buying a new home, you might be smart to invest in a Smart House.

The most revolutionary change in housing since indoor plumbing will be just one of the outstanding features in this year's Deseret News Home and Summer Living Show. The four-day event, offering an array of demonstrations and scores of informative booths, opens May 4 in the Salt Palace.Sponsored in cooperation with the Home Builders Association of Greater Salt Lake and the Newspaper Agency Corp., this year's free show will be combined again with the annual Showcase of Homes.

A highlight of the show will be a demonstration of the Smart House, offering a revolutionary wiring system that promises to change the way Americans enjoy, manage and control their houses.

Developed in a trend-setting research and development program spearheaded by the National Association of Home Builders, the wiring allows a homeowner to install one cable that handles all power and control needs. Regular home construction includes different wiring for electricity, low-voltage for doorbells and exterior lighting, thermostats, alarm systems, television antennae or cable TV, audio speakers, intercoms and telephones.

The Smart House wiring is combined into one cable designed to handle power distribution, control/data signal distribution and audio/video signal distribution.

In addition to simplicity of installation, the cost is a determining factor when planning for Smart House wiring installation, according to the experts.

And these experts will be just a few of those on hand to help the home buyer or remodeler.

The Home Builders Association will present an information area with photographs of new homes constructed by its members. The new dwellings, featured in the organizations's annual Showcase of Homes, are located throughout Salt Lake County and south Davis County.

After visiting the Salt Palace exhibits, showgoers are invited to tour the homes during regular open house activities during the week.

The HBA Remodeling Council, composed of architects, suppliers and remodelers, will provide just one of the informative seminars during the show. Show visitors are invited to bring sketches or plans for remodeling to gain professional tips for their project.

Other half-hour demonstrations will be presented daily with professionals providing information on many subjects, such as home decorating, summer meals, residential lighting techniques and installing lawn sprinklers.

This year's show has been expanded to four days to accommodate the crowds that attended previous exhibits.
