Passive Water Wall and Focusing Roof Aperture Solar-Heating Building Experiment. Final Technical Report, October 1977-June 1983

摘要

A passive water wall and focusing roof aperture solar-heating system has been constructed and has been operating successfully since the winter of 1981. This report summarizes the technical accomplishments under the scope of the grant effort, including two important modifications to the grant involving: (1) a data-acquisition-system installation at another building; and (2) a passive-solar-energy curriculum survey. Unfortunately, because the owner of the building has been involved in a lawsuit with the builder, final instrumentation, data collection, and evaluation have not been accomplished. However, the owner does report substantially lower annual fuel bills for heating and cooling (totaling approximately $200 per year). Because sensors have been placed in the building, the project would definitely merit a follow-up data collection effort when the owner has settled his dispute with the builder. (Reference CAPE-2832).
