   Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE

4. 2. Evaluation of Thermal Comfort and Night Ventilation in a Historic Office Building in Nordic Climate

   Author : Hossein Bakhtiari; Mathias Cehlin; Jan Akander; Abolfazl Hayati; Patrik Rohdin; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; historic buildings; office buildings; Nordic climate; thermal comfort; field on-site measurements; standardized questionnaire; building management system BMS ; night ventilation NV ; building energy simulation BES ; IDA-ICE; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Envelopes with low thermal performance are common characteristics in European historic buildings resulting in insufficient thermal comfort and higher energy use compared to modern buildings. There are different types of applications for the European historic buildings such as historic churches, historic museums, historic theatres, etc. READ MORE

5. 3. Improved building energy simulations and verifications by regression

   Author : Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

   Abstract : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

6. 4. Single Skin Glazed Office Buildings - Energy Use and Indoor Climate Simulations

   Author : Harris Poirazis; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Modern office buildings have high energy savings potential and potential for indoor climate improvements. During the nineties many office buildings with glass facades were built, in several cases with double skin glass facades. READ MORE

7. 5. Evaporative Cooling Tower and Chilled Beams. Design Aspects for Cooling in Office Buildings in Northern Europe

   Author : Bengt Bergsten; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pilot plant; cooling tower; simulation; low energy cooling; cooling tower model; free cooling; chilled beams; evaporative cooling; commercial buildings; hydronic cooling system;

   Abstract : The purpose of this thesis is to examine a comfort cooling system consisting of a hydronic cooling system with an evaporative cooling tower and chilled beams. The system has no conventional chiller. READ MORE
