  1. 1. Daylight compliance of multi-dwelling apartment blocks : Design considerations, evaluation criteria and occupant responses

    Författare :Iason Bournas; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :HUMANIORA; HUMANITIES; daylight; electric lighting; policy; regulation compliance; simulation; questionnaire; daylight metrics; perception; brightness; user preferences; urban density; block typology; room geometry; room function; room orientation;

    Sammanfattning : This thesis examines the daylight compliance of residential spaces, in particular apartments in multi-dwelling building blocks, and provides knowledge that may prove useful for the development of future daylight criteria for dwellings. The implications of design choices on daylight compliance of spaces and the effect of daylight criteria on the level of compliance are at the core of this work. LÄS MER

  2. 2. Performance in the Swedish Building Code : An Inquiry into the Consequences for Architectural Design of the Formulation and Assessment of Performance Requirements

    Författare :Marja Lundgren; Timothy Anstey; Fredrik Nilsson; Meike Schalk; Anne Beim; KTH; []
    Nyckelord :HUMANIORA; HUMANITIES; Architecture; architectural technology; performance-based regulation; performance requirement; energy performance; daylight metrics; tectonics; architectural representation; repertoire; context-dependent knowledge; Arkitektur; funktionskrav; energiprestanda; dagsljusfaktor; tektonik; repertoar; arkitekturteknik; Arkitektur; Architecture;

    Sammanfattning : This thesis investigates performance-based regulation in Sweden and its consequences for architectural design. In the last 50 years, there has been a transition from prescriptive to performance-based regulation, propelled by the drive to further innovation, productivity and competitiveness by expressing the functions expected of the buildings as performances.

  3. 3. Lighting simulation for a more value-driven building design process

    Författare :Anahita Davoodi; Thorbjörn Laike; Peter Johansson; Annika Moscati; Jönköping University; []
    Nyckelord :lighting simulation; lighting design; lighting quality; energy efficiency; perception;

    Sammanfattning : Concerns about global warming are increasing, hence, the urgency to cut carbon emissions. Reducing energy consumption, including lighting energy, is seen as the primary solution. Yet, solving the environmental factor should not come at the cost of other pillars of sustainable development. LÄS MER

  4. 4. Supporting evidence-based design using lighting simulations : A framework for lighting simulation of visual comfort in building design

    Författare :Anahita Davoodi; Myriam Aries; Peter Johansson; Thorbjörn Laike; John Mardaljevic; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lighting quality; visual comfort; lighting simulation; evidence-based design; field study; post-occupancy evaluation; Ljuskvalitet; visuell komfort; ljussimulering; evidensbaserad design; fältstudie; brukarutvärderingar;

    Sammanfattning : This research aims to integrate lighting simulation into the evidence-based design process for achieving improved lighting outcomes in built environments with a particular emphasis on visual comfort analysis in office settings. The objectives of the study include 1) understanding the current usage of lighting simulation tools, learning designers’ experiences' and needs, 2) providing a conceptual framework to integrate the use of lighting simulation in the evidence-based design (EBD) process, 3) testing the usage of the conceptual framework (named EBD-SIM) through two field studies.

  5. 5. Group-Theoretical Structure in Multispectral Color and Image Databases

    Författare :Thanh Hai Bui; Reiner Lenz; Björn Kruse; Jinhui Chao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group theory; PCA Principal Component Analysis ; CBIR; Content-based Image Retrieval ; filter; color; image; multispectral; database; Signal processing; Signalbehandling;

    Sammanfattning : Many applications lead to signals with nonnegative function values. Understanding the structure of the spaces of nonnegative signals is therefore of interest in many different areas. Hence, constructing effective representation spaces with suitable metrics and natural transformations is an important research topic. LÄS MER
