2. 1. Comfort Climate Evaluation with Thermal Manikin Methods and Computer Simulation Models

   Author : Håkan O Nilsson; KTH; []
   Keywords : thermal climate assessment; thermal environment; office environment; cabin; climate; CFD; thermal manikin; comfort zone diagram;

   Abstract : Increasing concern about energy consumption and thesimultaneous need for an acceptable thermal environment makesit necessary to estimate in advance what effect differentthermal factors will have on the occupants. Temperaturemeasurements alone do not account for all climate effects onthe human body and especially not for local effects ofconvection and radiation. READ MORE

4. 2. Modelling impact climate-related change on the thermal responses of lakes

   Author : Ana I. Ayala; Donald C. Pierson; Stéphane Goyette; Andreas Lorke; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Modelling; climate change; lakes; thermal structure; surface heat fluxes; extreme events;

   Abstract : In response to climate-related changes, lakes worldwide have experienced warmer surface water temperatures, shorter ice cover periods and changes in lake stratification. As these aspects of lake dynamics exert substantial control over nutrient availability, oxygenation and biogeochemical cycling, predicting changes in lake water temperature and stratification dynamics can improve our understanding of the consequences of warming on lake ecosystems.

5. 3. Microclimate and Thermal Comfort of Urban Spaces in Hot Dry Damascus- Influence of urban design and planning regulations

   Author : Moohammed Wasim Yahia; Boende och bostadsutveckling; []
   Keywords : HUMANIORA; HUMANITIES; Architecture; Arid zones; Damascus; Hot dry regions; Thermal indices; Urban climate; Built environment; Microclimate; Urban design; Climate; Climatic design; Planning regulations; Thermal comfort; Urban planning;

   Abstract : The aim of this study is to develop better understanding of the relationship between microclimate and urban design in the hot dry city of Damascus. This is done by studying the impact of urban regulations on microclimate in different urban design patterns in modern Damascus. READ MORE

6. 4. Comfort climate evaluation with thermal manikin methods and computer simulation models

   Author : Håkan O. Nilsson; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; equivalent temperature; subject; thermal manikin; mannequin; thermal climate assessment; heat loss; office environment; cabin climate; ventilated seat; computer model; CFD; clothing-independent; comfort zone diagram; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

   Abstract : Increasing concern about energy consumption and the simultaneous need for an acceptable thermal environment makes it necessary to estimate in advance what effect different thermal factors will have on the occupants. Temperature measurements alone do not account for all climate effects on the human body and especially not for local effects of convection and radiation. READ MORE

7. 5. Possibilities of using thermal mass in buildings to save energy, cut power consumption peaks and increase the thermal comfort

   Author : Jonathan Karlsson; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete; aggregates; heat capacity; thermal properties; thermal conductivity; thermal inertia; thermal mass; time constant; Energy storage;

   Abstract : The aim of this project was to generate knowledge to enable us to take advantage of heat storage in heavy building structures with regard to as energy savings, better thermal indoor climate, and reduced peak powers. This could include buildings that can function without energy input during cold periods, buildings that give a robust indoor climate without installed cooling, and buildings with good thermal comfort also in case of higher outdoor temperatures resulting from global warming.
