Estimation of Indoor Temperature for a Direct-Gain Passive Solar Building

AbstractThis paper examines the effects of passive solar heating produced by a direct passive solar system consisting of windows for direct insolation in a residential building located in Nis, Serbia. A mathematical model is presented to calculate the temperature in the room of a building with a direct passive solar system, depending on the size of the opening, window slope (slanting or vertical position), orientation of the room, and the size of the eave above the window (if it is installed). Using the proposed mathematical model, the inner air temperatures of a thermally insulated residential building with a direct passive solar system are analyzed for different building orientations during the period between January and March of 2008. Two software packages are developed to support the proposed mathematical model.

Integrated system of occupational safety and health and fire protection of the fire rescue brigades members

ABSTRACT The objective of the conducted research is the identification and determination of requirements of members of fire rescue brigades during operations in the conditions of high risk in order to minimize the possibilities for injury incidence during the intervention. The research is focused on examination, determination and identification of factors affecting the increasing number of occupational injuries of members of fire rescue brigades during interventions. Hypothetical framework of the research problem consists of general hypothesis and six special hypotheses. Results suggest that almost all respondents believe that their skills and abilities are applicable in the intervention phase, but less than a half believe that their skills are applicable in prevention phase. Two-thirds of respondents stated that in their organization they have support for further education and upgrading while a half of respondents stated that they need education concerning identification, assessment and management of risks that can lead to emergency situations.
