This
web site is to be developed as a case study similar to Carefree
House case study. The Atascadero project was developed by Harold
Hay in the mid 1970's, with the help of a grant from DOE, to demonstrate
that a residence could be comfortably conditioned, on a year round
basis, with only passive energies. The primary strategy was the
use of roof ponds to store and transfer heat to and from the living
space. In this demonstration, as in the Carefree project, Comfort
is attained by controlling surface temperatures. (see other photo

FUTURE
WORK:
The
house was recently renovated with the intent of performing a second
study to more rigorously investigate its performance. In March 2001,
Harold Hay led a group to inspect the house to begin planning. Besides
Mr.Hay, the group included Margot McDonald, Jeff Maddren and grad
students of Cal Poly Pomona, Marty Kluck, Cal Poly and Pomona graduate
and former research assitant for the house, and Harvey Bryan and
David Scheatzle of Arizona State University.
The
objective was to review the house's construction, photograph, and
determine what data should be collected to evaluate the performance
of the house. It is proposed that Cal Poly personnel, led by Jeff
Maddren, collaborate with ASU personnel on this project. ASU would
make data available on its web page and make comparisons with the
Carefree House using visualization techniques currently used in
Carefree case study. The original thermocouples installed at the
house have been cut off where they stub out from the floor slab.
Whether or not any are still operational and can be reconnected
remains to be seen. Moveable insulation controls were operational
and data from this system should be obtainable.
We then proceeded to the University's canyon property, where we
viewed a mobile thermopond test facility constructed to evaluate
its performance in various climate zones in the US.
Proposed tasking for a second Atascadaro study:
SLO
will:
1. Set up existing Cal Poly weather station at site and connect
to PC data recorder.
2. Purchase and install sensors and data recorder (See attached
sensor list).
3. Purchase and install data recorder (recommend National Instruments
components to include web module) and connect to PC. Recommend
that Labview software be used.
4. Install dedicated phone line for web and data access.
5. Provide for remote operation of moveable insulation.
6. Calibrate data
ASU will:
1. Format data for presentation on existing web site
2. Use collected data to visualize operation
3. Compare performance of Atascadaro house with that of the
Carefree house.
4. Make continual improvements to the web site with successive
generation of visual presentations to where the web site is
useful for educational institutions and the profession by showing
how maximizing passive thermal storage performance of envelope
components, particularly the ceiling/roof assembly can extend
the passive comfort periods in a residence.
5. Using Energy Plus, simulate the performance of the Atascadaro
house and compare with actual data. Report results to the Energy
Plus programmers.
6. Manage student research assistants in producing the above
tasks. Travel to SBSE and ASES conferences to report on the
work. |
