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 ... -
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 ... -

(Journal article, 2020-04-24)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 ... -
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
(Peer reviewed; Journal article, 2020)Compact roofs are normally built without organic materials between the vapour barrier and the roof membrane due to moisture safety risks. However, laboratory measurements indicate that organic materials could be used ... -
Control strategy for battery-supported photovoltaic systems aimed at peak load reduction
(Journal article; Peer reviewed, 2019)The use of photovoltaic (PV) technologies is one of the key means for achieving the balance between operational power demand and generation in net Zero Energy Buildings (nZEBs). However, direct use of PV power on-site is ... -
Data-driven analysis of electricity use for office buildings: a Norwegian case study
(Peer reviewed; Journal article, 2021)Buildings are major consumers of primary energy and main contributors to carbon emission. To improve energy efficiency, it is essential to understand the characteristics of energy use in buildings. This study uses an in-use ... -
Development of a data-driven model to characterize the heat storage of the building thermal mass in energy planning tools
(Peer reviewed; Journal article, 2021)In the one hand, energy planning tools compute the cost-optimal investment in the energy system minimizing life cycle costs (LCC). These tools often consider optimal control. The building (or cluster of buildings) is ... -
