As part of a drive to improve energy efficiency and reduce fuel poverty, Camden Council specified Q-Bot Underfloor Insulation which uses a robotic system  to spray foam onto the underside of the floor. 

The 48 properties included various housing types, differing in age and size. The energy savings achieved by the upgrades were modelled in SAP using elemental U-values for the individual floors and the airtightness test results of each property. This enabled the energy improvements to be calculated against a range of scenarios with alternative retrofit measures.
