The net zero energy-building (Net-ZEB) concept promotes buildings that use the grid as the virtual energy storage medium. They exchange a large amount of energy with the grid and rely heavily on these energy exchanges to fulfill their yearly zero balance. Nevertheless, grid hosting capacities are limited and they can only accept a limited spread of such buildings. Large scale application of Net-ZEBs in the building stock can only be realized if well-designed energy solutions are in place. As current ...

The housing sector is important for future energy savings and greenhouse gas emission mitigation. A dynamic, stock-driven and segmented dwelling stock model is applied for dwelling stock energy analyses. Renovation activity is estimated as the need for renovation during the ageing process of the stock, in contrast to exogenously defined and often unrealistic renovation rates applied in other models. The case study of Norway 2016–2050 shows that despite stock growth, the total theoretical estimated ...
