Accelerated climate aging of building materials and their characterization by Fourier transform infrared radiation analysis
(Journal article; Peer reviewed, 2012)Building materials and their durability and aging are essential to the performance of buildings and their building physical aspects over time. Accelerated climate aging investigations are carried out in order to study the ... -
Aging effects on thermal properties and service life of vacuum insulation panels
(Journal article; Peer reviewed, 2011)Vacuum insulation panels (VIPs) represent a high-performance thermal insulation material solution offering an alternative to thick wall sections and large amounts of traditional insulation in modern buildings. Thermal ... -
Developing low-conductance window frames: Capabilities and limitations of current window heat transfer design tools - State-of-the-art review
(Journal article; Peer reviewed, 2008)While window frames typically represent 20—30% of the overall window area, their impact on the total window heat transfer rates may be much larger. This effect is even greater in low-conductance (highly insulating) windows ... -
Hot Box Investigations and Theoretical Assessments of Miscellaneous Vacuum Insulation Panel Configurations in Building Envelopes
(Journal article; Peer reviewed, 2011)Vacuum insulation panels (VIPs) are regarded as one of the most promising existing high performance thermal insulation solutions on the market today as their thermal performance typically range 5—10 times better than ... -
Hot-Box measurements of highly insulated wall, roof and floor structures
(Journal article; Peer reviewed, 2016)The purpose of this study was to investigate how natural convection in air-permeable glass wool insulation affects the thermal transmittance in walls, roofs and floor structures. The results can be used to evaluate the ... -
Implementation of Radon Barriers, Model Development and Calculation of Radon Concentration in Indoor Air
(Journal article; Peer reviewed, 2011)Norway has some of the highest concentrations of radon in indoor air in the world. Based on large-scale surveys by direct measurements of radon in indoor air it has been estimated that nearly 9% of the housing stock has ... -
Improving Thermal Insulation of Timber Frame Walls by Retrofitting with Vacuum Insulation Panels – Experimental and Theoretical Investigations
(Journal article; Peer reviewed, 2011)Many of the Norwegian buildings from the 1960s–1980s with timber frame walls are ready for retrofitting. Retrofitting of these buildings with vacuum insulation panels (VIPs) may be performed without significant changes to ... -
Local loss coefficients inside air cavity of ventilated pitched roofs
(Journal article; Peer reviewed, 2018)Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ... -
Measurement of the convective moisture transfer coefficient from porous building material surfaces applying a wind tunnel method
(Journal article; Peer reviewed, 2013)This article presents results for the average convective moisture transfer coefficients of several porous building material samples exposed to airflow. The experimental measurements explore the effect of the various air ... -
Robustness Classification of Materials, Assemblies and Buildings
(Journal article; Peer reviewed, 2014)Reliable methods are needed for classifying the robustness of buildings and building materials for many reasons, including ensuring that constructions can withstand the climate conditions resulting from global warming, ... -
The Path to the High Performance Thermal Building Insulation Materials and Solutions of Tomorrow
