The K-12 Project Background
• The domestic household sector is one of the largest consumers of electrical energy inthe EU, consuming around 30% of the total electrical energy supply, distributed over140 million households
• The development of new technologies and the adoption of the Energy label havehelped to reduce the energy consumption of individual electrical devices but theincrease number and time they are in use resulted in increased energy consumption
2K-12 CONFIDENTIAL
increase number and time they are in use resulted in increased energy consumption
• Cold appliances - refrigerators and freezers - accounted for 14.5% of householdenergy consumption in 2010. Currently, most households still use old, energy-inefficient cold appliances

Concentrations of carbon dioxide in the atmosphere have now touched 400 part-per-million and greenhouse gaspollution, but there is no question that the world continues to inexorably climb toward higher levels of
greenhouse gases concentrations: at present pace, the world could reach 450 ppm in a few short decades.

How far can the PU foam Thermal Conductivity bereduced?
• Smaller cell size
• Lower foam density
• Low thermal conductivity (k) of the gas chosen as blowing agent
• Cell gas mixture with high % low k gas vs. CO2 and Air
however,
18K-12 CONFIDENTIAL
however,
combination of all these options must be considered,
for example
• Reduced density will decrease the solid conduction contribution, but will alsoincrease the radiation contribution due to thinner cell walls
K-12 Project is active in all these aspects and works on reducing all heat transfer andthermal contributions to maximize energy saving
