  1. 11. Modelling LCC for Different Indoor Climate Systems

    Författare :Dennis Johansson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kallt klimat; bostäder; kontor; skolor; samlingslokaler; inomhusklimat; VVS; uppvärmning; ventilation; luftkonditionering; livscykelkostnader; kostnader; optimering; beräkningsmetoder; beräkningsmodeller; teori;

    Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. LÄS MER

  3. 12. Demand Controlled Ventilation (DCV) Systems in Commercial Buildings. Functional Requirements on Systems and Components

    Författare :Mari-Liis Maripuu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DCV; CO2-sensors; indoor climate control; energy efficiency; CAV; mixedgas;

    Sammanfattning : Demand controlled ventilation (DCV) is considered as an energy efficient solution forair-based cooling and indoor air quality control. Considerable energy savings can beachieved when the airflow rate is continuously adapted to the actual load condition. LÄS MER

  4. 13. Air diffusion and solid contaminant behaviour in room ventilation : a CFD based integrated approach

    Författare :Gery Einberg; Sture Holmberg; hazim Awbi; KTH; []
    Nyckelord :Technology; CFD modelling; airflow rate; ventilation efficiency; diffusers; solid contaminants; IAQ; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : One of the most fundamental human needs is fresh air. It has been estimated that people spend comparatively much time in indoor premises. That creates an elevated need for high-quality ventilation systems in buildings. The ventilation airflow rate is recognised as the main parameter for measuring the indoor air quality. LÄS MER

  5. 14. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

    Författare :Mats Dahlblom; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential apartment buildings; building services systems; energy use; hvac; hydronic heating system; heating control; feedback control loop; indoor temperature measurements; individual metering and billing; indoor temperature variations; thermal comfort; vertical temperature gradient; case study;

    Sammanfattning : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". LÄS MER

  7. 15. Cat allergen exposure at school : evaluation of sampling methods and allergen avoidance strategies

    Författare :Anne-Sophie Karlsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :School; child; cat allergen; Fel d 1; exposure; sampling; allergen avoidance; cat owner;

    Sammanfattning : Cat allergy is the most common allergy among school children in Sweden. Cat allergen is ubiquitous in school premises and other public places and this indirect exposure to cat may induce symptoms among cat sensitized children with asthma. LÄS MER
