- Reduced energy consumption is an important strategy for climate change mitigation. Buildings, worldwide, accounts for 40 % of the primary energy use and 24 % of greenhouse gas emissions.There are studies and publications indicating that problems with high indoor temperature during summer are increasing in residential buildings designed as passive houses and low-energy buildings.The objective of this study is to investigate and quantify the effect of different measures that may reduce the risk of high indoor temperature for dwellings in summer. The result may serve as guidelines for architects and consultants in early design stages.This study examined the effect of different measures that may be applied to reduce the indoor temperature in dwellings in summer by simulations using IDA ICE 4.5. Hence, the results should only be used for residential buildings.The simulations show that for residential buildings the duration of high indoor temperature increases when taking the step from the standard concept to the low-energy concept, regardless of investigated option. However the increase in duration is low compared to decreases of high indoor temperature, possible to reach by different airing strategies or different measures to reduce thesolar insolation.Airing must be presumed in order to achieve and maintain a high thermal comfort during summer without mechanical cooling. High indoor temperatures cannot be solved with only shading and window sizes. Therefore; Always create possibilities for airing, which requires operable windows, doors or airing panels. Mechanical automated control may be a suitable feature in order to reducethe effort required from the residents. Secondly; consider large external horizontal solar shading. Note that the required size of a horizontal shading in relation to window height usually is higher on facades facing east and west.

- DELLSON P., NILBERT M., BENDAHL P-O., MALMSTROM P. & CARLSSON C. (2010) European Journal of Cancer Care Towards optimised information about clinical trials; identification and validation of key issues in collaboration with cancer patient advocates Clinical trials are crucial to improve cancer treatment but recruitment is difficult. Optimised patient information has been recognised as a key issue. In line with the increasing focus on patients' perspectives in health care, we aimed to study patients' opinions about the written information used in three clinical trials for breast cancer. Primary data collection was done in focus group interviews with breast cancer patient advocates. Content analysis identified three major themes: comprehensibility, emotions and associations, and decision making. Based on the advocates' suggestions for improvements, 21 key issues were defined and validated through a questionnaire in an independent group of breast cancer patient advocates. Clear messages, emotionally neutral expressions, careful descriptions of side effects, clear comparisons between different treatment alternatives and information about the possibility to discontinue treatment were perceived as the most important issues. Patients' views of the information in clinical trials provide new insights and identify key issues to consider in optimising future written information and may improve recruitment to clinical cancer trials.
