New energy control system 'learns' your habitsPassivSystems showcases 'intelligent' energy kit

12 January 2010


A new home energy monitoring system claims to help reduce energy bills by 'learning how people live' and automatically adapting energy usage according to your activities.

The PassivEnergy home energy monitoring kit includes sensors designed to connect to your heating, hot water and electrical appliances, tracking your regular usage via an individual online account.

A touchscreen controller allows you to pre-programme and monitor your energy and heating settings - but PassivSystems says the PassivEnergy 'intelligent' control system also 'automatically makes the most efficient use of energy throughout the home and doesn't make extra work for the user'.

PassivEnergy system

The PassivEnergy monitoring system was one of the products showcased at this year's Consumer Electronics Show in Las Vegas. Features include:

  • 'Adaptive occupancy' to programme your boiler according to whether you're in, out, asleep or on holiday
  • Heating controls able to adjust automatically based on outside temperature and 'learn' when to turn heating up or down
  • Hot water controls to only heat the amount of water you need
  • Standby controls that automatically switch off appliances on standby

Long term, PassivEnergy wants the systems to link up to 'special dynamic demand tariffs that let offer you the best prices, and use your white goods at the cheapest times'.

The PassivEnergy system will be available to buy at from late March or early April 2010 and will be priced between £200 and £300. PassivSystems told Which? that a partnership with an energy company may also be in the pipeline - in which case customers could get a free energy kit as part of a 'smart' tariff plan.

Because the PassivEnergy system directly controls your boiler and heating system, it needs to be installed by a qualified professional.
