Building design and material properties influence thermal performance and energy consumption for residential and commercial buildings. Insulated wall, floor and roof systems provide an innovative combination of excellent thermal conductivity, thermal mass and low air-infiltration. This practical combination of properties in one system provides an excellent thermal insulation material and permits peak energy usage in the building to be shifted to off-peak hours, thus reducing operation cost for building users and owners, improving comfort of living and reducing the demand on power generation facilities. One can look at Substantial reduction in air conditioning tonnage and huge savings in monthly electricity bills up to 40%. It is very economical for centrally air-conditioned buildings, public utility structures, government buildings, schools, hospitals, theatres, shopping complexes, and so on.
