Componentes de condução da luz natural em edifícios multifamiliares

Abstract

Daylight can provides human health and well-being, as well as economic benefits. Daylight can creates interesting interiors supportive of human health and energy can be saved by dimming down or switching off electric lighting that are not needed. The surrounding, the building design and the daylight system are key elements of the greater or lesser possibility of use of the natural light. This Master s dissertation aims to study the potential use of the natural light, considering the minimum window size required on João Pessoa Paraíba Brazil legislation (JOÃO PESSOA, 1971) for residential spaces illuminated by pass-through and conduction components. A series of computer simulations were used in evaluating the daylight availability, provided by Daysim. There were carried on 480 simulations by associating five residencial rooms living room/bedroom 01; bedroom 02; maid s room; kitchen and bathroom and six design variants opaque and transparent sill; protruding and enclosed balcony; balcony s depth (1,20; 1,50; 2,00; 2,50 e 3,00 m), maximum plot ratio allowed; floor level (ground level and fourth floor); and North, East, South, and West facade orientations. Daylight Autonomy (DA) and Useful Daylight Illuminance (UDI) are the performance indicators used to predict the rooms performance using dynamic daylight simulations. Around 40% of the models have fell-short levels of Useful Daylight Illuminance. Protruding or enclosed balcony, opaque or transparent sill, and floor level affects the levels of natural lighting in rooms.
