Indoor climate in a zero energy building - An analysis of the thermal environment and indoor air quality
Søgnen, Odin Budal (Master thesis, 2015)Buildings are responsible for around 40 % of the world s energy use, hence also for huge amounts of climate gases, both directly and indirectly. The building industry needs to become a part of the solution of an energy ... -
Investigations of Different Control Strategies for Heat Pump Systems in a Residential nZEB in the Nordic Climate
Clauss, John; Sartori, Igor; Alonso, Maria Justo; Thalfeldt, Martin; Georges, Laurent (Chapter, 2017)The paper investigates different control strategies for a ground source heat pump of a Norwegian residential zero emission building, with detailed dynamic simulations (here using IDA ICE). These rule-based controls aim at ... -
Lessons learned after one-year of use of a highly efficient neighbourhood in Norway
Alonso, Maria Justo; Line, T.; Næss, Erling; Ramstad, Randi Kalskin; Breuhaus, Peter Helmut Herbert; Midttømme, Kirsti (Journal article; Peer reviewed, 2019)2020Park is an innovative installation in Stavanger, Norway. This installation provides heating and cooling via a ground source heat pump (GSHP). The system combines eight 220m deep boreholes, with an air to brine heat ... -
Measured load profiles and heat use for “low energy buildings” with heat supply from district heating
Ulseth, Rolf; Lindberg, Karen Byskov; Georges, Laurent; Alonso, Maria Justo; Utne, Åmund (Journal article; Peer reviewed, 2017)In the development towards nearly zero energy buildings (nZEB) the load profiles for the heat demand and the heat use of the buildings are expected to be changed considerably compared to the situation today. This change ... -
