Home automation can save cash, help environment

Home automation may be the next big trend in what consumers can do for the environment. By setting up a wired (or even wireless) system, homeowners can optimize lighting level efficiency, cut heating and cooling energy costs, and deactivate energy-consuming devices and appliances even when no one is home.

“An automated home brings together security, fire, lighting, temperature control, audio, video, pool, spa, drapery control, sprinklers, and anything else that you want so that these systems can talk to each other and work together,” reports Jay McLellan of Home Automation ( www.homeauto.com), a leading manufacturer of integrated automation and security systems for residential and commercial use.

One easy way to dip a toe in the water of home automation is to swap out regular light switches for occupancy sensors, which can tell whether a room is occupied and will turn lights on and off accordingly.

Upgrading to a programmable thermostat that will regulate heating and cooling according to a set schedule is another way to reduce energy consumption and save money. Some newer models, such as Nest from California-based Nest Labs ( www.nest.com), can program themselves based on occupants’ routines, and also offer the option to adjust heating and cooling settings remotely via the Internet. A built-in occupancy sensor signals to the Nest whether and when people are around, and the unit then adjusts heating or cooling accordingly. The newest version, Nest 2, can tell within a half hour when occupants have vacated and will set the indoor temperature to a more energy efficient level on its own.

Shelling out $249 for Nest’s so-called “learning thermostat” may seem a little extreme, but the feature may save enough money and electricity to pay for itself in as little as a year. Nest thermostats can replace most existing thermostats and do not require upgrading to a newer furnace or air conditioning system – although newer heating and cooling systems, especially those that meet the U.S. government’s EnergyStar criteria for efficiency, do tend to save much more energy than older ones. Some 56 percent of the energy used in a typical American home goes to heating and cooling, so automation can make a big difference for the environment and the pocketbook.

Beyond lighting and thermostats, whole-house automation systems connect home electronics (including appliances and security systems) into an integrated wireless network that allows occupants to control from off-site, including via the Internet or a mobile phone app. A Sylvania Z-Wave Starter Kit from SmartHomeUSA.com ( http://bit.ly/15NadCF) is one affordable way to get started with whole-house automation; you can start small and gradually add electronics to the system.
