Abstract With international awareness of the need to decrease greenhouse gas emissions, Danish government set a target be fossil fuel-free by 2050. To achieve that, existing buildings will retrofitted with energy-saving technologies such as improved thermal insulation. In Denmark, larger mass building stock from around 1850 1940s is preservation worthy. The construction typically solid brick wa...

The adoption of phase change materials (PCMs) is a promising solution for the improvement building energy performances and indoor comfort, integration geopolymer concrete (GPC) allows recycling reducing demand raw in production. Both contribute to carbon dioxide emission lifecycle. In this frame, paper proposes complete numerical approach selecting optimal wall package made GPC PCMs Mediterrane...

This is fact that area heat flow perception on inner thewalls at an angle transfer surface. Convective exchangenear inhibition air movement in other areas,so amount comin...

The overall life of oil-immersed power transformers depends on the long-term life of the oil–paper insulation system throughout continuous operation. Studying the reliability assessment methods for oil–paper insulation can help determine the reliability level of power transformers accurately, and ensure their safe and stable operation. In the present paper, the life of oil–paper insulation is p...
