However, there is often a gap between the high-level goals, ... -
Development of a data-driven model to characterize the heat storage of the building thermal mass in energy planning tools
Georges, Laurent; Storlien, Elin; Askeland, Magnus; Lindberg, Karen Byskov (Peer reviewed; Journal article, 2021)In the one hand, energy planning tools compute the cost-optimal investment in the energy system minimizing life cycle costs (LCC). These tools often consider optimal control. The building (or cluster of buildings) is ... -
Electricity analysis for energy management in neighbourhoods: Case study of a large housing cooperative in Norway
Sørensen, Åse Lekang; Sartori, Igor; Lindberg, Karen Byskov; Andresen, Inger (Journal article; Peer reviewed, 2019)As a basis for energy management in apartment blocks, this paper characterises electricity use in a Norwegian housing cooperative with 1,058 apartments.
