Sartori, Igor; Sandberg, Nina Holck; Brattebø, Helge (Journal article; Peer reviewed, 2016)This paper presents a model based on dynamic material flow analysis, general in its principles and applied to the dwelling stock of Norway for exemplification. The algorithm at the core of the model is presented in the ... -
Dynamic modelling of national dwelling stocks: Understanding phenomena of historical observed energy demand and future estimated energy savings in the Norwegian dwelling stock
Sandberg, Nina Holck (Doctoral theses at NTNU;2017:36, Doctoral thesis, 2017)Residential buildings are responsible for 24% of the global final energy consumption, and the housing sector is important for future mitigation of greenhouse gases. Scenario models are important tools for estimation of the ... -
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. In 2018, the average specific electricity delivery to apartments and ... -
Energy flexibility of Norwegian residential buildings using demand response of electricity-based heating systems: A study on residential demand side flexibility, heating system control, and time-varying CO2eq. intensities of the electricity mix
Clauß, John (Doctoral theses at NTNU;2019:225, Doctoral thesis, 2019)The transition to a sustainable energy system requires a shift to intermittent renewable energy sources, which call for increased flexibility on the demand side. Heat pumps offer the possibility to couple the electricity ... -
