The pervasiveness and growing complexity of software systems are challenging software engineering to design systems that can adapt their behavior to withstand unpredictable, uncertain, and continuously changing execution environments. Control theoretical adaptation mechanisms have received growing interest from the software engineering community in the last few years for their mathematical groundi
Since the beginning of the 21st century, straw-bale buildings are reappearing in the world; however, their thermal performances were not thoroughly investigated up to now. The purpose of this study is to analyze thermal behavior and energy performance of a straw-bale building in Switzerland. Using Pleiades+Comfie Software, building designs have been studied to understand the best way to mitigate o
This work describes the research conducted in order to assess possible changes and uncertainties in future energy performance of the residential building stock in Stockholm. The investigation is performed on a sample of 153 existing and statistically selected buildings and covers the period of 1961-2100. Four uncertainty factors of the climate have been considered: global climate models, regional
Most of the last 20 years in Sweden have been mild and wet compared to the 1961-1990 climate reference period. After a few relatively cold years in the mid-1980s, practically all years have been warmer than the preceding 30 years average. During the indicated period, an increase of moisture-related problems (mould growth) was observed in ventilated attics, a moisture sensitive building part.This w
Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways. Increased structural loads from wind and water, changes in energy need and decreased moisture durability of materials are some examples of the consequences. Future climate conditions are simulated by global climate models (GCMs). Downscaling by regional climate models (RCMs) provi
Studying the effects of the climate change on buildings contains two major fields: energy consumption and durability. In the field of durability the moisture effects on the building play a significant role. In Sweden the last 10-15 years have been mild and wet compared to previously. Precipitation increased considerably during the period (+11 %), whereas temperature increase were weaker (+ 0.7 oC)
Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. In Sweden, most of the last 20 years have been mild and wet compared to the 1961-1990 climate reference period. Future needs and risks of the building sector depend on the future climate wh
Overheating in summer is a problem in buildings with large glass area and low heat capacity constructive materials. Adding some thermal mass to the building is a way to overcome this problem. A new method is using removable thermal mass. This is called Controlled Active Mass (CAM). The CAM is an extra thermal mass which is placed inside the building to decrease energy demand for cooling and heatin
Under changing climate conditions, acceptable functionality of buildings and their adaptation to climate are required. More rain and extreme conditions in future make buildings and the built environment more vulnerable. There are currently several scenarios regarding possible future climatic conditions. Results from the impact analysis of climate change can be significantly affected by the selecte
The effects of possible climate changes on a cold attic performance are considered in this work. The hygro-thermal responses of the attic to different climate data conditions are simulated using a numerical model, which has been made using the IBPT. Cold attic, which is the most exposed part of the building to the environment, is classified as a risky construction in Sweden. Mould growth on intern
During the last few years global warming and its effects on climate have been a debated issue. The building industry plays a large part in the human activities which can be influenced by the climate change. Energy consumption and durability of buildings depend a lot on the weather conditions. Many of the developed countries will set their strategies on the probable future conditions considering th
There is much concern about the effects of possible future climate changes on buildings. The future climate scenarios are based on numerical simulations. Each scenario of a climate model is the result of some changes in the boundary or initial conditions, emission scenario, etc. Consequently each weather scenario has different sources of uncertainty which affects the building simulation results.
