  1. 1. Thermal models of buildings : determination of temperatures, heating and cooling loads : theories, models and computer programs

    Författare :Kurt Källblad; Institutionen för byggvetenskaper; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Computer Programs; Windows; Infiltration; Comfort; Walls; Indoor Climate; Climate; Ventilation; Cooling Load; Heating Load; Buildings; Thermal Models; Building Physics; Energy; Byggnadsteknik;

    Sammanfattning : The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. LÄS MER

  3. 2. Modelling the Variability of Bending Strength in Structural Timber - Length and Load Configuration Effects

    Författare :Tord Isaksson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; code; reliability-based design; Weibull; test standard; load configuration effect; length effect; weak section; machine grading; visual grading; variability; Structural timber; bending strength; simulation; monte carlo simulation.; Building construction; Byggnadsteknik;

    Sammanfattning : The load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber.

  5. 4. Optimization of ground-coupled systems for heating and cooling of buildings

    Författare :Jüri Naumov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-cooling; brine temperature; heat pump; ground system; heating demand; storage; building load; cooling demand; Borehole;

    Sammanfattning : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. LÄS MER
