Perspectives of double skin façade systems in buildings and energy saving

Abstract: One of the most important methods of saving energy in a building is by carefully designing its facade. A ‘double skin facade’ is optimally one of the best options in managing the interaction between the outdoors and the internal spaces. It also provides some architectural flexibility to the design. Recently it has received much attention as opposed to the more typically glazed curtain wall. This is because of its ability to efficiently reduce energy and therefore saves cost. The amount of energy saved depends on the climate and the design chosen. The design of the DSF involves decisions on geometric parameters, glass selection, ventilation strategy, shading, daylighting, aesthetics, wind loads, and maintenance and cleaning cost expectations. DSF has an impact on several aspects of the design phase of a building. For example, thermal properties, acoustic characteristics and daylighting are affected in the exploitation phase of the building. In addition, in terms of building safety point of view, fire propagation maintenance or glazing thermal break must be taken into account. Currently, little work has been done on the behaviour of DSFs in hot and humid climates. This paper shall review previous studies made on double skin facade systems (DSFS) in buildings.

Situational antecedents and outcomes of organizational politics perceptions

Abstract: A model of perceptions of organizational politics was developed and tested using a sample of 208 Malaysian employees from diverse occupations and organizations. Results of a path analysis on the survey data showed that job ambiguity, scarcity of resources, and trust climate were significant predictors of perceptions of organizational politics. Perceptions of organizational politics, in turn, mediated the effects of these situational antecedents on job stress, job satisfaction, and turnover intention. Specifically, employees who perceived a high level of politics in their workplace reported higher levels of stress, lower levels of job satisfaction, and higher levels of intention to quit than did employees who perceived a low level of politics. Implications of the findings and suggestions for future research are discussed.
