A Simplified Power Sizing Method for the Correct Building Integration of Wood Stoves
Thalfeldt, Martin; Skare, Anders; Georges, Laurent; Skreiberg, Øyvind (Journal article; Peer reviewed, 2019)Wood stoves are widely used in dwellings for space heating, however transient heat output and relatively large heat emission might cause problems with over-heating in new well-insulated buildings. This paper introduces a ... -
Energy efficiency of hydronic space-heating distribution systems in super-insulated residential buildings
Georges, Laurent; Iwanek, Tomasz; Thalfeldt, Martin (Chapter, 2017)In space-heating (SH) dominated climates, superinsulated building envelopes, such as passive houses (PH), are often promoted to drastically reduce SH needs. Using hydronic SH distribution in PH, thermal losses from pipes ... -
Evaluation of Simplified Space-Heating Hydronic Distribution for Norwegian Passive Houses
Georges, Laurent; Alonso, Maria Justo; Woods, Ruth; Wen, Kang; Håheim, Fredrik; Liu, Peng; Berge, Magnar; Thalfeldt, Martin (ZEB Project report;, Research report, 2017)This technical report combines research results from the Norwegian Research Center on Zero Emission Buildings (ZEB) and a competence project about simplified hydronic distribution funded by Husbanken. In the Norwegian ... -
Field investigation of thermal comfort level of patients and surgical staff in operating rooms at St Olavs hospital
Helena Kuivjõgi (Master thesis, 2019)I helsetjenester og sykehusmiljøer er det viktig å kunne forutsi termisk komfort som en parameter for inneluftkvalitet. Ustabile termiske forhold er kritiske i operasjonsrommet og kan redusere arbeidseffektiviteten og øke ... -
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 ... -
Parametric Energy Simulations of a Nordic Detached House Heated by a Wood Stove
Thalfeldt, Martin; Skare, Anders B.; Georges, Laurent; Skreiberg, Øyvind (Peer reviewed; Journal article, 2020)Wood stoves are widely used in Nordic countries. They offer a good opportunity to use biomass for space-heating and to reduce the peak power of all-electric buildings. However, wood stoves are highly concentrated heat ... -
Thermal zoning during winter in super-insulated residential buildings
Selvnes, Eirik (Master thesis, 2017)In the work of reducing the energy consumption of buildings, the passive house concept has been developed as a possible solution. These buildings have a low energy need for space-heating and is therefore often equipped ... -
Validation of a method to select the optimal nominal power of a wood stove in residential buildings
Skare, Anders Bagøien (Master thesis, 2018)Wood stoves are prominent space heating strategies for detached residential buildings in European countries. However, there are no guidelines for selecting the correct wood-stove nominal power, based on building performance. ... -
Validation of a transient zonal model to predict the detailed indoor thermal environment: case of electric radiators and wood stoves
Georges, Laurent; Thalfeldt, Martin; Skreiberg, Øyvind; Fornari, Walter (Journal article; Peer reviewed, 2019)In building performance simulation (BPS), zonal models are intermediate models between standard models assuming perfectly-mixed room air and Computational Fluid Dynamics (CFD): they aim to predict the air temperature and ... -
Validation of a Zonal Model to Capture the Detailed Indoor Thermal Environment of a Room Heated by a Stove
Thalfeldt, Martin; Georges, Laurent; Skreiberg, Øyvind (Chapter, 2019)Using wood stoves is a common space-heating strategy in the Nordic countries. Currently, the lowest available nominal power of wood stoves is significantly oversized compared to the design space-heating load of highly-insulated ... -
Validation of a Zonal Model to Capture the Thermal Stratification in a Room Heated by a Stove
Georges, Laurent; Thalfeldt, Martin; Skreiberg, Øyvind (Chapter, 2018)Using wood stoves is a common space-heating strategy in the Nordic countries. The power oversizing of a stove for a given building might deteriorate the indoor thermal environment, for instance with large thermal stratification. ... -
Wood burning habits and its effect on the electrical energy demand of a retrofitted Norwegian detached house
Felius, Laurina C; Thalfeldt, Martin; Georges, Laurent; Hrynyszyn, Bozena Dorota; Dessen, Fredrik; Hassan Mohamed, Mohamed Hamdy (Journal article; Peer reviewed, 2019)Using firewood as a space heating source is a popular solution in Norwegian housing and can significantly reduce the electrical energy demand of houses. This study analysed habits and reasons for using a wood stove from ...
