Iluminação e comportamento do usuário: estudo de edificação em Belo Horizonte, MG

Abstract

The human being experiences the space through sensory mechanisms and their well-being, your comfort and your balance dependent on adequate stimulation of these mechanisms. The best way to do this is naturally, promoting contact with the natural cycles, such as daylighting. However, with the increasing consolidation and vertical growing of cities, with openings defined in terms of aesthetics and often inadequate guidelines often makes it difficult to human needs. Artificial lighting has been supplying this, but it is often used without considering the availability of daylight. So, the accomplishment and integration of natural and artificial lighting are needed for user comfort and energy efficiency by reducing consumption, and to enable this integration we observe the development of light design that employ techniques and devices control that harness daylight and use artificial light to complement according to identified need. However, user behavior does not always correspond to the expected, is for convenience or subjective preferences. The purpose of a descriptive nature, this final work specialization was to identify whether the technical integration of daylight with artificial through building automation, converted into an actual improvement in user comfort and quality of an office environment whose building was subject to the labeling of energy efficiency in buildings by the prescriptive method of RTQ - C, regarding the variables analyzed for the partial label lighting as well as user behavior procedure. The method used in the development of this research was the case study based on literature review and field. The building was selected among the buildings that have built energy efficiency of commercial buildings, and public service label, and was considered an office environment, in which a survey of the physical environmental conditions, measurement of lighting levels was performed, and interviews about the behavior of users in the use and appropriation of space. The results revealed that lighting levels are consistent with the needs of their activities, as well as their distribution in the environment through the use of artificial lighting systems, but that strategies aimed at reducing consumption through integration of systems with daylight and depend drive devices by users do not happen the way they were designed, especially in relation to the control of blinds and switches. Thus, although the design, installation and classification consider the potential for reducing consumption, in practice the result was not observed. As a contribution to the development of labeling and energy efficiency programs, as well as other certifications, procedure is the importance of user awareness in the use and appropriation of space to use and effective reduction of energy consumption.
