See Them Save
A Lutron HomeWorks lighting control system also helps the Levinsons save energy by dimming lights and programming preset scenes so that only the lights needed for particular tasks come on. But Frank is going beyond that, replacing many of the traditional incandescent bulbs with dimmable compact fluorescent lamps (CFLs) and even higher-efficiency LEDs (light-emitting diodes). He says a lot of the home’s 50-watt halogen lights are being replaced by 5-watt LEDs. These LEDs can’t dim all the way down to 1 percent, but that’s a compromise the Levinsons will gladly live with, as they’re saving a lot of energy.

The Levinsons can see much of what they are using in electricity via the Agilewaves energy-monitoring system. It’s connected through an Ethernet network and viewed through a web interface by Frank. SoundVision is planning to display data on the Crestron touchpanels, though for now Quisisem says the web interface is more robust.

Sensors monitor the electrical, solar, solar thermal, and water systems and send that information to a data acquisition box, and a PC server maintains the database.

Frank can see when his nephews are in the downstairs apartment playing on the computer all night. And the monitoring capability has enabled him to identify problems with the system. For example, after the photovoltaic solar system was installed, he noticed irregularities with the data associated with it and realized that one of the inverters used to convert the DC power from the solar system to AC for the home’s electrical use wasn’t working properly. There would be no way to know that from simply reading a monthly utility bill.

For now, Frank can see that he’s producing more energy from the solar system than he is using, though he plans to add a hot tub and a lap pool. That will use up more juice—and he’s sure to know exactly how much.
