Nuuanu YMCA Honolulu, Hawaii solar-water-heating project. Final report
The Nuuanu YMCA is a combination athletic facility and men's dormitory. The building is of masonry construction, and includes a four-story dormitory on which the solar water heating system was mounted. The water storage tank was placed at a higher elevation than the collectors so that the majority of the system would operate in thermosyphon. A small system with a pump is included on another roof of the building and is circulated into the same storage tank. A pump was later added to the thermosyphon system. The system has 182 collector panels, each consisting of a polycarbonate box, low iron tempered glazing, copper waterways and painted aluminum absorber. The water is stored in a 4000-gallon storage tank on the roof. The system provides domestic hot water and serves as a preheat system for the existing building water heaters. The system was installed and met performance criteria. An acceptance test plan is described and data are given. The thermosyphon system was found not to be efficient compared to the pumped system. System operation, maintenance and controls are described, and YMCA energy consumption data are given. Blueprints are included. (LEW)
