Acceptable air velocities using demand-controlled ventilation for individual cooling
(E3S Web of Conferences;Volume 172, 2020. 12th Nordic Symposium on Building Physics (NSB 2020). Article Number: 09002, Journal article; Peer reviewed, 2020-06-30)One of the main challenges in highly insulated buildings is the increasing share of energy demand for cooling. New solutions for low energy cooling are needed. Individual cooling by demand-controlled ventilation and use ... -
Air flow door barrier for airborne infection isolation rooms
(E3S Web of Conferences;Volume 111 E3S Web Conf., 111 (2019) 02063, Conference object, 2019)Airborne Infection Isolation Rooms (AIIRs) are used in hospitals to counter the spread of airborne infections. These rooms usually work well as long as the doors to the patient rooms are closed. However, passage through ... -
Climate change impact on the degradation of historically significant wooden furniture in a cultural heritage building in Vestfold, Norway
(E3S Web of Conferences;Volume 362 (2022),11003, Peer reviewed; Journal article, 2022-12-01)Climate change is expected to significantly affect the interior climate of old, leaky buildings without HVAC systems.
