WHEB Ventures invests in home energy management company PassivSystems

Established in 2008 and headquartered in the UK, PassivSystems is developing the new PassivEnergy
home energy management system. Without forcing energy consumers to change their lifestyles, Passiv's system monitors and automatically optimises energy consumption in the home including heating, hot water and electrical appliances. PassivSystems is using this first round of external finance to establish a major commercial partnership and launch its first commercial product in early 2010.

James McNaught-Davis, Managing Partner at WHEB ventures said: “We are delighted to be making our first investment in smart grid technology, the market for which is estimated to be worth €30 billion (£27 billion) over the next five years. PassivSystems has a unique offering which will form a critical part of the smart grid infrastructure and help householders to save money and cut carbon emissions.”

“The CEO and his team are seasoned telecommunication technology professionals who are applying their knowledge and experience to the smart grid market. We look forward to helping them grow their business rapidly to exploit this considerable market opportunity.”

Colin Calder, Founder and CEO of PassivSystems said: “WHEB Ventures is a world class VC and we have established a very strong partnership with them. They have done an outstanding job in delivering both commercial and political opportunities over the last nine months and we look forward to bringing PassivEnergy to market in early 2010 with their support.”

“PassivEnergy will revolutionise how consumers manage energy in the home. We are confident that our ground breaking product will save the consumer up to 28% on their energy bills and make their homes more comfortable.”

The PassivEnergy system is based around the PassivHub, the heart and brain of the intelligent home. The PassivHub communicates wirelessly to internal and external temperature sensors and appliance controls installed around the home and via the internet to the PassivEnergy service. PassivEnergy uses its innovative ‘Adaptive Occupancy Control’ function to optimise energy use. Over time this function ‘learns’ when the householder uses energy and when it can be saved. It then controls energy consumption across multiple devices in the home.

It is estimated that in the UK, 60% of the energy used in the home is for space and water heating and as much as 8% for electrical appliances on standby. Further energy is wasted by appliances that are left ‘on’ but are not in use.

UK Trade & Investment (UKTI), the government body promoting British business in international markets, will be presenting a slice of the British technology industry at this year's Consumer Electronics Show in Las Vegas, Nevada. PassivSystems has been selected by UKTI as one of ten promising British technology companies to exhibit, giving them the chance to showcase their products and services on a global platform.
