(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The need for renovation and energy retrofitting of Danish social housing from the 1960s and 1970s is substantial. Such energy retrofits often include the installation of mechanical ventilation systems with heat recovery ... -
Performance assessment and clinical validation of OR ventilation systems
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Microbiological burden of room-air in operating theatres is a known risk factor for surgical site infections. However, it is unclear how to best evaluate efficacy and efficiency under routine clinical conditions. Moreover, ... -
PERFORMANCE OF THE BLENDING FACTORS APPROACH FOR MODELING THE INTERFACIAL FORCES IN BUBBLE COLUMNS OPERATING AT HIGH GAS HOLD UP
(SINTEF Proceedings;6, Chapter; Peer reviewed, 2020)Gas-liquid bubble columns are commonly used in the process industry due to their ease in construction and their excellent performances. However, the formulation of numerical models of such industrialscale systems is ... -
Performance, psychological, and physiological effects of office noise
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)Speech is a common disturbance in offices. Irrelevant speech influences performance and subjective estimations. However, not many studies have examined simultaneously the consequences of irrelevant speech on humans regarding ... -
Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous ... -
Phytoremediation of Airborne Particulate Matter in Indoor Environments
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)This research is motivated by the urgent need to protect people from the adverse health effects of PM2.5 (particles smaller than 2.5 μm in size) exposure by using potted plants as air filters in indoor environments. We ... -
Planning a low carbon urban area in Helsinki with dynamic energy simulations
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)The city of Helsinki has a target to achieve carbon neutrality in 2035. The objective of this project was to use energy simulations to study and compare multiple different energy production alternatives for new Malmi ... -
POD-interpolation based prediction of indoor airflows
