See how the revolutionary internal wall insulation process triumphed at the UK’s most prestigious sustainability awards
See how WHISCERS™ has reduced fuel bills and CO2 emissions at a tower block retrofit in Dorking.
WHISCERS™ (Whole House In-Situ Carbon and Energy Reduction Solution) is a revolutionary process for Internal Wall Insulation (IWI) of hard-to-treat social housing that uses laser technology for the first time, enabling residents to continue to live in their homes throughout the refurbishment works.
The patented process was unveiled at an award-winning low-carbon retrofit of a three-storey council owned Victorian terraced house in Bertram Street, Camden in November 2010. The eco measures installed in the home, including IWI, have greatly improved energy efficiency and reduced fuel bills by nearly £600 a year. Carbon emissions have been cut by 77%.
The latest project to benefit from WHISCERS™ is at Dorking in Surrey, where 104 flats in two tower blocks have been retrofitted with the tenants remaining in situ. The project finished six weeks ahead of schedule and tenants will benefit from reduced fuel bills to the tune of £445 per annum.
WHISCERS™ uses laser scanning to measure the dimensions of a room, off-site insulation board cutting and rapid installation to complete the process. As it is a low mess process that is faster and less disruptive than traditional IWI methods, residents can continue to live in their homes, saving housing providers thousands of pounds in relocation costs.
The innovative process is the result of a partnership between United House and the Sustainable Energy Academy. It was developed as a volume solution for retrofitting older and hard-to-treat social housing stock on a nationwide scale to address the duel challenges of reducing carbon emissions in existing stock and fuel poverty for residents, whilst at the same time making homes warmer and more energy efficient.
There are seven million of these homes in the UK - two million in London alone. Up to 40% of the heat loss in these homes passes through the external walls and in most cases, due to planning restrictions, IWI is the only realistic option.
WHISCERS™ is faster, better and more cost-effective than traditional insulating methods. With low mess, little noise and minimal disruption, as well as being able to insulate a room in 90 minutes with residents remaining at home, WHISCERS™ is an ideal way of retrofitting hard-to-treat properties.
WHISCERS™ is a three part process:
WHISCERS™ provides many benefits over traditional IWI methods:
WHISCERS™ is a win, win solution for housing providers and residents for transforming hard-to-treat properties into easy-to-heat homes.
In 2011 WHISCERS™ won Inside Housing magazine's Innovation Award and the Energy Institute's Innovation Award in recognition of the contribution that the process offers to the energy efficiency of solid walled homes in the UK.
In November 2012, WHISCERS™ won the 'Building Fabric of the Year' category at the Retro Expo Awards. The judges commented: "The system demonstrated great process innovation with high potential impact".
In June 2013 WHISCERS™ received the Ashden UK Gold Award 2013 - the most prestigious sustainable energy award in the country - from Sir Jonathon Porritt, co-founder of Forum for the Future, at a ceremony at The Royal Geographical Society in London.
