Chapter 2: outlines
initial-stage
planning parameters, such as basic decisions on shape
and window size, as well as
specific functional objectives of the daylighting
strategies. Application of daylight strategies
for windows and rooms is also discussed, along with
advice on how to choose systems
for specific sky types.
Innovative daylighting systems work by redirecting
incoming sunlight and/or skylight to
areas where it is required, and, at the same time,
controlling glare. These systems are
particularly appropriate where an interior space is too
deep for conventional windows to
provide adequately uniform lighting or where there are
external obstructions. Systems that
control glare as well as the quantity of daylight
entering a space may also be a good solution
for shallow rooms; thus these systems also merit
consideration as innovative.
A daylighting strategy can be characterized by its
performance parameters. These parameters
include quantity of light, distribution of light and
glare, cost, and energy use.
