  2. 1. Spatial variations of the urban climate and its influence on thermal comfort and behaviour

    Author : Fredrik Lindberg; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sky view factor; air temperature; surface temperature; GIS; raster modelling; mean radiant temperature; globe temperature; the SOLWIEG-model; human behaviour; outdoor activity;

    Abstract : The increased number of people living in urban areas emphasises the need for an improved understanding of how the urban climate affects human activity and behaviour. The spatial and temporal variation of climate within cities is an important factor in people’s health and well-being. READ MORE

  4. 2. Modelling of the daytime and night-time urban thermal environment

    Author : Shiho Onomura; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; urban thermal environment; microclimate modelling; air temperature; mean radiant temperature; nocturnal cooling rates; synoptic weather types;

    Abstract : The world’s urban population is expected to increase over the coming decades. To maintain and improve the health and well-being of urban citizens, it is important to increase our knowledge and develop methods for evaluating the urban thermal environment to support urban planning.

  5. 3. Evaluation of the Performances of Electrically Heated Clothing

    Author : Faming Wang; Ergonomi och aerosolteknologi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electrically heated vest EHV ; heating efficiency; cold weather clothing; air velocity; clothing combination; thermal resistance; air temperature;

    Abstract : Cold weather garments are necessary for people who are exposed to cold environments (below -5 °C). The weight and bulkiness of such a cold weather clothing ensemble may limit human activity and reduce the productivity. In order to solve these problems, a slim garment with a built-in heating element could be useful. READ MORE

  6. 4. Development of the Wind and Air Temperature Sensor of the ExoMars 2022 HABIT Instrument

    Author : Álvaro Soria-Salinas; María-Paz Zorzano Mier; Javier Martin-Torres; Patel Manish; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mars; Atmosphere; Heat transfer; Forced convection; Wind; Space instrumentation; Exploration; Atmospheric science; Atmosfärsvetenskap;

    Abstract : This work presents the development, validation and calibration of the air temperature sensors (ATS) and the air and wind retrieval method of the HABIT (HabitAbility: Brines, Irradiation and Temperature) instrument. HABIT is one of the two European  payloads of the ESA/Roscosmos ExoMars 2022 mission that will land at Oxia Planum (18.20° N, 335. READ MORE

  7. 5. Some Factors Influencing Thermal Comfort and Air Quality in Residential Buildings. Field Measurements and Laboratory Tests

    Author : Ulf Krüger; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation; air intakes; thermal comfort evaluation; air velocity; indoor air quality; air supply devices; occupation zone; air temperature fluctuations;

    Abstract : The main prerequisite for applying a specific ventilation system in residential buildings is that the demands set upon the indoor air quality and thermal climate can be satisfied. If this cannot be guaranteed using a simple exhaust system, a system with treated supply air, i.e. balanced ventilation, should be considered. READ MORE
