The ZEN Definition - A Guideline for the ZEN Pilot areas. Version 1.0
(ZEN Report;11, Research report, 2018)The objective of this report is to provide a guideline for how the assessment criteria and key performance indicators (KPIs) covered under each category of the ZEN definition (GHG emissions, energy, power/load, mobility, ... -
Thermal comfort and occupant adaptive behaviours in naturally ventilated hospital wards in a hot-humid post-epidemic context
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)In free-running hospitals, which comprise a significant part of the healthcare infrastructures in countries with the weakest public health systems, unmet spacecooling demand can exacerbate indoor overheating. To date, we ... -
Thermal comfort in a hospital isolation room – A laboratory study
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)The aim of this study is to examine thermal comfort, perception of air movement, and perceived symptoms of persons lying in patient bed in a hospital isolation room. The study had a repeated measures design with two test ... -
Thermal Comfort Level of Patients and Surgical Staff in Operating Rooms at Nordic Hospital
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)In healthcare facilities and hospital environment, it is essential to enable thermal comfort for occupants. Unstable thermal conditions in the operating room (OR) will influence the performance of surgical staff and ... -
Thermal Energy Systems in ZEN: Review of technologies relevant for ZEN pilots
(ZEN Report;3, Research report, 2018)This report reviews state-of-the-art on thermal energy systems for neighbourhoods. Main focus is on technologies related to 4th generation district heating (4GDH), biomass combined heat and power (CHP) systems, ground ... -
Thermal Insulation of Clothing: Assessment of Cleanroom Clothing Ensembles
(SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)In cleanrooms, the thermal optimization is not always possible, thus the suitable selection of clothing is important to achieve thermal comfort. In the case of specific cleanroom clothing, the values of thermal insulation ... -
Thermodynamic Properties of The Binary Mixture of Monoethanolamine and Carbon Dioxide
(SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)Homogenous densities in the liquid phase and VLE data were measured for the monoethanolamine and carbon dioxide system. The density data were obtained on five isotherms in a temperature range between 313.15 K and 353.15 ... -
