Use of low cost pollutant sensors for developing healthy demand controlled ventilation strategies - A case study in four primary school classrooms
(Master thesis, 2019)I de fleste industriland står bygg for omlag 40% av det totale energiforbruket, og en betydelig andel av dette går til drifting av ventilasjonsanlegg. Behovsstyrt ventilasjon (DCV) er et tiltak som ofte benyttes for å ... -
The use of machine learning to determine moisture recovery in a heat wheel and its impact on indoor moisture
(Peer reviewed; Journal article, 2022)Balanced mechanical ventilation equipped with heat recovery has been widely adopted in cold climates to ensure an acceptable indoor environment in energy-efficient buildings. An acknowledged trend to achieve more energy ... -
Use of Membrane Energy Exchanger in Ventilation: Odour Sensory Measurement
(Peer reviewed; Journal article, 2022)Membrane energy exchanger (MEE) for a new generation of energy efficient heating, ventilation and air conditioning (HVAC) systems has attracted wide attention. As MEE has been increasingly employed, extensive studies of ... -
The use of non-cavitating coupling fluids for intensifying sonoelectrochemical processes
(Peer reviewed; Journal article, 2020)For the first time, we have investigated the beneficial effects of non-cavitating coupling fluids and their moderate overpressures in enhancing mass-transfer and acoustic energy transfer in a double cell micro-sonoreactor. ... -
Use of Optimization in Evaluation and Design of Liquefaction Processes for Natural Gas
(Doctoral thesis at NTNU;2015:33, Doctoral thesis, 2015)Liquefied natural gas (LNG) is a fast growing energy carrier suitable for transport of natural gas when the distance from source to market is long and/or the volumes are moderate. In order to liquefy the natural gas, and ... -
Use of renewable energy and hydrogen storage for a carbon-negative village
(Bachelor thesis, 2023)Denne bacheloroppgaven ble skrevet som en del av et større prosjekt, Nothing Hill, der et gammelt sykehus fra 1955 skal ombygges til en moderne studentcampus. Et av m˚alene med dette prosjektet er ˚a skape en karbonnegativ ... -
Using a cellular metal structure to improve the thermal performance of a latent heat storage system
(Master thesis, 2020)Termisk energilagring har potensial for mer effektiv og miljøvennlig energibruk, ved at overflødig varme lagres til senere bruk. Ved vedfyring er det ikke uvanlig at tilgjengelig varme overstiger varmebehovet og varmelagring, ... -
Using a segmented dynamic dwelling stock model for scenario analysis of future energy demand: The dwelling stock of Norway 2016–2050
(Journal article; Peer reviewed, 2017)The housing sector is important for future energy savings and greenhouse gas emission mitigation. A dynamic, stock-driven and segmented dwelling stock model is applied for dwelling stock energy analyses. Renovation activity ... -
Using Building Energy Monitoring to Verify Building Energy Performance
(Doctoral Theses at NTNU, 1503-8181;2009:233, Doctoral thesis, 2009)This thesis has two main goals: (1) to develop a linear regression model of the heat consumption of space heating and ventilation systems and (2) to evaluate operation and maintenance problem detection, by comparing actual ... -
Using crowdsourced data to estimate the carbon footprints of global cities
(Peer reviewed; Journal article, 2022)Cities are at the forefront of the battle against climate change. However, intercity comparisons and responsibility allocations among cities are hindered because cost- and time-effective methods to calculate the carbon ... -
Using Dividing Wall Columns (DWC) in LNG Production: deviding wall column, double dividing wall column, prefractionator arrangement, Petlyuk column, NGL recovery, distillation
(Master thesis, 2014)The Dividing Wall Columns (DWC) distillation has attracted growing interest for fractionation of multicomponent mixture due to reduction of energy consumption, auxiliary equipment and space within fractionation process. ... -
Using Energy Storage Systems to Provide Grid Support for Ferry Charging
(Bachelor thesis, 2022)Den norske staten har som mål å få en fossilfri kollektivtrafikk innen 2025, dette inkluderer fergeflåten. For mange fergestrekk vil elektrifisering være den beste løsningen. For å kunne gjen- nomføre dette må distribusjonsnettet ... -
Using Fiber-Optic Sensors to Give Insight into Liquid-Solid Phase Transitions in Pure Fluids and Mixtures
(Peer reviewed; Journal article, 2020)Fiber optic sensors offer a new and unique way to detect and analyze phase transitions, due to their small thermal mass and inert material. This paper presents and demonstrates a dual-sensor system to detect and analyze ... -
