Radiant heating wall-to-wall carpet for energy efficiency space heating of existing non-residential buildings (RADCARPET)
Start date: Oct 1, 2013, End date: Sep 30, 2015 PROJECT  FINISHED 

Energy efficiency is using less energy while maintaining an equivalent service. EU set a target for 2020 of saving 20% of primary energy consumption. Nearly 40% of the energy is consumed by buildings. Large efforts are being invested in future low energy buildings, but the reality is that existing buildings represent 99% of the stock. The EPBD recast sets minimum requirements for existing buildings: Member States must set targets for the transformation of existing buildings into near zero energy buildings by 2014 (consuming 40-60 kWh/m2). Thus the current average energy consumption (150 -300 kWh/m2) will need to be reduced by <75%. Few innovative technical systems in the market are directed and optimised for the efficient use of energy in existing buildings. Therefore RADCARPET will be a radiant heating wall-to-wall carpet covering the floor surface of non-residential buildings (offices, hotels and educational buildings) that will work as a space heating system. The radiant heat from the RADCARPETED floor is naturally energy-efficient and will save up to 75% of thermal energy (in comparison to radiators and HVAC) an still produce an improve thermal comfort. RADCARPET will be tuft carpet including a thermal conductive tuft made of novel fibers, intermediate non-woven electro-thermal heating fabric made of novel conductive textile fibres, an insulating secondary backing, and a SMART control system. Being a carpet, it will be a non-intrusive, simple and inexpensive solution for building renovation to reduce energy consumption, thus overcoming the obstacles for existing building refurbishment (expensive, lengthy works, inconvenient). The economic impact of RADCARPET in 11 EU countries is 107€ million in 5years post project. Our consortium is composed of R-STAT (French conductive fiber producer, coordinator), MAXI (German non-woven manufacturer), TISCA (Swiss tuft carpet manufacturer) and CASACLIMA (Italian end user agency certification of building energy efficiency).
