Indoor environmental quality in the residential sector significantly influences the occupants? wellbeing, having consequences on health and productivity. Integration of strategies of solar energy use, in passive system in the building architecture, is intended to reduce not only the energy consumption for heating, from non-renewable sources, but also to provide a healthy and comfortable environment for occupants. This paper presents the results of a study that aimed to assess the quality of the indoor environment ...

The magnetorheological (MR) fluids include ferromagnetic and paramagnetic particles suspensions with sizes included between 0.03 and 10 ?m, located in a carrier fluid (usually mineral oil). The complex fluid viscosity strong depends of magnetic field applied. Each particle can be considered a small magnet, which tends to align in the direction of the magnetic field. The magnetorheological fluids have the ability to change their viscosity when they are introduced into a magnetic field, due to the aligned particles ...
