A dataset of wind-driven rain measurements on a low-rise test building in Norway
(Journal article; Peer reviewed, 2007)Semi-empirical models and especially numerical simulation models based on Computational Fluid Dynamics (CFD) are increasingly being used to calculate wind-driven rain (WDR) on building facades. The development, verification ... -
A probabilistic-based methodology for predicting mould growth in façade constructions
(Journal article; Peer reviewed, 2017)Predicting mould growth on façade constructions during design is important for preventing financial loss, and ensuring a healthy and comfortable indoor environment. Uncertainties in predicting mould growth are related to ... -
Air heating of passive houses in cold climates: Investigation using detailed dynamic simulations
(Journal article; Peer reviewed, 2014)The passive house (PH) standard was originally defined for Central Europe and has subsequently been applied to many cold climate countries. In these conditions, the relation between this standard and the air heating (AH) ... -
An analytical method for evaluating and visualizing embodied carbon emissions of buildings
(Peer reviewed; Journal article, 2020)Greenhouse gas emissions associated with buildings constitute a large part of global emissions, where building materials and associated processes make up a significant fraction. These emissions are complicated to evaluate ... -
Assessing the indoor air quality and their predictor variable in 21 home offices during the Covid-19 pandemic in Norway
(Peer reviewed; Journal article, 2022)In this study, concentrations of pollutants: formaldehyde, carbon dioxide (CO2), and total volatile organic compounds (TVOC) and parameters: indoor room temperature and relative humidity (RH) were measured in 21 home offices ... -
Characterization of the density-driven counter-flow through a doorway using Large Eddy Simulation
(Peer reviewed; Journal article, 2022)The density-driven bidirectional flow through an open doorway is of prime importance for ventilation and heat distribution between rooms in buildings. Although this flow has been extensively studied in the past, some ... -
Development of the ASHRAE Global Thermal Comfort Database II
(Journal article; Peer reviewed, 2018)Recognizing the value of open-source research databases in advancing the art and science of HVAC, in 2014 the ASHRAE Global Thermal Comfort Database II project was launched under the leadership of University of California ... -
Driven precast concrete geothermal energy piles: Current state of knowledge
(Peer reviewed; Journal article, 2023)Geothermal energy piles are increasingly luring attention in the construction industry as a cost-effective and environmental friendly solution for heating and cooling buildings. Energy piles are used as the primary unit ... -
Effect of forced convection on the hygrothermal performance of a wood frame wall with wood fibre insulation
(Peer reviewed; Journal article, 2021)Wood-based thermal insulation materials have interesting hygroscopic characteristics because of their high moisture capacity. The present paper investigates the moisture conditions in wood-frame walls with wood fibre thermal ... -
Embodied greenhouse gas emissions in structural materials for the German residential building stock - Quantification and mitigation scenarios
(Peer reviewed; Journal article, 2023)Embodied emissions in construction materials make a relevant contribution to carbon emissions worldwide. While this has been broadly recognised, only little attention has been paid to the role of load-bearing structures ... -
Empirical validation and local sensitivity analysis of a lumped-parameter thermal model of an outdoor test cell
(Journal article, 2018)This paper presents the experimental validation of a thermal model describing the ZEB Test Cells Laboratory, located at the Gløshaugen campus of NTNU and SINTEF in Trondheim, Norway. Besides, a local sensitivity analysis ... -
Estimating dynamic climate change effects of material use in buildings — Timing, uncertainty, and emission sources
(Peer reviewed; Journal article, 2021)Material use in buildings affects the climate over centuries, however, temporal aspects are often ignored in Life Cycle Assessment (LCA). Results too often promise uncontested precision of impacts occurring far into the ... -
Estimating the impact of indoor relative humidity on SARS-CoV-2 airborne transmission risk using a new modification of the Wells-Riley model
(Peer reviewed; Journal article, 2021)A novel modified version of the Wells-Riley model was used to estimate the impact of relative humidity (RH) on the removal of respiratory droplets containing the SARS-CoV-2 virus by deposition through gravitational settling ... -

(Journal article; Peer reviewed, 2023) -
Evaluation of low-cost formaldehyde sensors calibration
(Peer reviewed; Journal article, 2022)Low-cost sensors (LCS) are becoming ubiquitous in the market; however, calibration is needed before reliable use. An evaluation of the calibration of eight identical pre-calibrated formaldehyde LCS is presented here. The ... -
Experimental study on the exposure level of surgical staff to SARS-CoV-2 in operating rooms with mixing ventilation under negative pressure
(Peer reviewed; Journal article, 2022)The purpose of this study was to reveal the exposure level of surgical staff to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from the patient's nose and wound during operations on COVID-19 patients. The ... -
