This paper presents part of an on-going research
project in the College of Architecture at Texas A&M
University. This research investigates how lightshelf
daylighting delivery systems can manipulate sunlight
and daylight both in terms of their light and heat by
shading view apertures below the shelf to reduce solar
heat gain and glare and by reflecting light deep into the
space through the daylight aperture above the shelf. It
also investigates how to provide view with good
interior lighting in terms of light levels, distribution,
and glare.
Evaluation of these systems are based on two
different experiments. The first uses scale-models for
daylighting evaluation. Methodology of the research is
presented as well as results and evaluation for part of the
first experiment. The second experiment will use
computer program simulations for energy evaluation
that include reducing lighting and cooling loads and
shaving peak loads, especially, when used with selective
low-e glazing for office buildings in hot climates
