Focus: Daylight and Lighting
Contact: Yan Chen chen335@purdue.edu
Objective: To use
sunlight more effectively and reduce indoor lighting energy
requirements.
Introduction:
As concern
for the sustainability movement has mounted, implementing
low-energy infrastructure has become an important concern.
Buildings account energy for 48% of the total energy
consumption in the United States. (Ref.1) Lighting in turn
accounts for 30% of the average building's energy
consumption.
It
is a common experience to enter a fully illuminated room
.
In
classroom and dining halls with sufficient natural light,
artificial lighting frequently remains
on.
Some
people close their blinds if the sunshine grows
uncomfortably bright, and then turn on their artificial
lights when it is too dark.
……
Well, they are all about the energy saving in daylighting
& lighting. As you may find it out by yourself, there
are more cases.
Why not participate in our sub-committee to work on the
energy saving in daylighting & lighting sector for
sustainable development on campus, in communities? You will
learn what efficient daylighting is, and how it can change
our daily life.
Activities
planned for this semester:
Help People
Choose the Efficient Lighting Source
-Find
data about what percentage of light bulbs used on campus,
in surrounding communities, and public buildings are
efficient.
-
Calculate how
much energy could be saved if all inefficient bulbs were
exchanged for efficient bulbs.
-
Write a report
suggesting lighting efficiency improvements based upon our
study.
Efficient Use
of Daylight Education:
-
Study lighting
controls and daylighting design
-
Invite a
professor from the Department of Architectural Engineering
to lecture on about Lighting & Daylighting.
-
Measure light
intensity in classrooms, libraries, other public places
using a luxometer. Compare our findings with the brightness
standard to find out how many places are over-lighted.
Efficient Bulb
Installation
-
Apply for
grants to hold an “efficient bulb exchange” workshop for
providing sustainable daylighting information; and to
distribute brochures for personal housing applications.
Activities
(planned for future):
Efficient
Multi-individual Office Lighting Study
-
Perform a
survey about personal office lighting (include employee
feelings about lighting use)
-
Analyze the
results, and submit a report suggesting ways in which the
office lighting can be made more efficient and sustainable.
