Proposal
for the 2004 SBSE Retreat For Theme #3
A. Objectives: There are 2 major
objectives for this presentation.
1. To
show attendees how they can build a conceptually clear heliodon of any diameter
(e.g. 12 ft.) for only a few thousand dollars (see attached image). Large heliodons allow the testing
of larger models and the participants of more onlookers. Working drawings will be supplied for
free.
2. To
show attendees how to teach graphical methods of solar design. Solar responsive projects can be
designed, analyzed, and presented by means of correctly drawn sunbeams. The quantity, quality, and
appropriately timed entry of solar radiation can be established with the
described graphical methods. By
means of 10 worksheets, the attendees will experience how I teach sunbeams,
shadows, and sun puddles. Each
attendee will receive a second set of worksheets for use at their home
university.
B. Agenda:
1. The first 30
minutes will be used to explain how and why build a large conceptually clear
heliodon.
2. The
remaining 60 minutes will be used as a workshop where the attendees will fill
out the worksheets I use to teach graphical methods for solar design. Each participant should bring a
protractor, straight edge, and sharp colored pencils. I will bring some for those who forget.
C. Knowledge and Information to be
Acquired:
1. Each
participant will understand how and why to build a large conceptually clear heliodon. They will also have access to a free
set of working drawings.
2. Each
attendee will have the knowledge and tools to teach a very clear and effective
graphical technique for illustrating sunbeams that are not in the plane of the
building section. Serious
misconceptions occur when sunbeams are drawn incorrectly which frequently
happens when analyzing the sunŐs effect at times other than 12 noon on a N-S
section. Furthermore, even
12 noon becomes problematic when the building is not aligned with the cardinal
directions of the compass. Being
able to draw sunbeams correctly not only prevents misinformation, but also
helps the students better understand how sunbeams can be collected or rejected
as appropriate.
D. Audiovisuals needs:
I need a video projector and document camera. If that combination is not available, I
can use an overhead projector instead.
