An experimental investigation on the flow resistance over a porous gravel-bed surface and its non-porous counterpart
(Journal article; Peer reviewed, 2018)This paper presents preliminary results from laboratory experiments which were specifically designed to determine the flow resistance over a water-worked gravel-bed and its impermeable counterpart (cast-bed). The technique ... -
Analysis of energy signatures and planning of heating and domestic hot water energy use in buildings in Norway
(Journal article; Peer reviewed, 2019)Widespread introduction of low energy buildings (LEBs), passive houses, and zero emission buildings (ZEBs) are national target in Norway. In order to achieve better energy performance in these types of buildings and ... -
Analysis of monthly and daily profiles of DHW use in apartment blocks in Norway
(Peer reviewed; Journal article, 2020)Profiles of domestic hot water (DHW) use give valuable information for achieving energy saving in buildings. In this article, analysis of monthly and hourly profiles in apartment blocks in Norway was performed. The aim was ... -
A Building Automation and Control micro-service architecture using Physics Inspired Neural Networks
(Peer reviewed; Journal article, 2022)In this work, we present a micro-service architecture which defines a Digital Twin (DT) framework for adaptive building automation and control. The DT framework primarily involves the orchestration of several containerized ... -
Building Energy Performance Evaluation of a Norwegian single-family house applying ISO-52016
(Peer reviewed; Journal article, 2022)In the following work, we have implemented a version of the hourly method in the ISO 52016-1:2017 standard, informed by the central input table in the SN/TS 3031:2021 specification, including a building energy supply system ... -
Calibration and validation of physics-based data-driven models for simulating the thermal behavior of indoor spaces in an assisted living facility
(Peer reviewed; Journal article, 2024)A case study represented by an assisted living facility in Norway is modeled utilizing physics-based data-driven digital twin (DT) of the indoor thermal spaces with indoor temperature. Autoregressive Distributed Lag (ARDL), ... -
Can we meet the requirement for ultra-clean operation room (10CFU/m3) with dilution ventilation?
(Journal article; Peer reviewed, 2019)The objective of this study is to analyse what conditions may, and may not take place during surgery in a dilution ventilated operating room (OR), to fulfil an ultra-clean requirement (10 CFU/m3). To achieve the objective, ... -
A case study on solar, wind and hydro energy resource potential of Prizren region in Kosovo
(Peer reviewed; Journal article, 2020)Prizren is a city located in the south part of Kosovo with approximately 90,000 inhabitants and land area of 640 km2. The region is covered with distinct geographical features, that favor penetration and deployment of ... -
Characteristics of failure mass and safety factor during rainfall of an unsaturated slope
(Journal article; Peer reviewed, 2016)Water is an important factor triggering destabilization of soil masses in slopes, particular in unsaturated condition. Rainfall and snow melting are some of the main sources of natural water which frequently induce unsaturated ... -
Climate change impacts and fungal decay in vulnerable historie buildings at Svalbard
(Peer reviewed; Journal article, 2020)This paper emphasises on degradation of wood in cultural heritage structures at Svalbard. Nowhere else does global heating occur faster. Negative impacts of climate change will increase the strain on wooden structures ... -
climify.org: an online solution for easy control and monitoring of the indoor environment
(Journal article; Peer reviewed, 2019)Real energy performance of new and retrofitted buildings often consistently differs from expectations. While occupants might complain about poor indoor climate, the energy use in such buildings is often higher than expected, ... -
CO2-based grey-box model to estimate airflow rate and room occupancy
(Journal article; Peer reviewed, 2019)In the existing building stock, heating, cooling and ventilation often run on fixed schedules assuming maximal occupancy. However, fitting the control of the HVAC system to the building’s real demand offers large potential ... -
Compact wooden roofs with smart vapour barrier – Pilot project experiences
