"Twenty students in the author's Communlty Design class undertook individual small scale design interventions in the Halifax Downtown that would enhance public amenity through the use of passive solar and daylighting techniques. These interventions, worked out to the detail of the Design Esqu isse, were opportunistic in the sense that they involved metamorphose.,; to settings in the urban fabric that lent themselves to such Interventions and not new built environments expressly designed for solar heat and light. The initial stage was the channeling of Intervention Opportunities Research into five groups of Windows, Atria , Clerestories,, Sunspaces and Trombe Walls Hybrids were discovered, doubts began to appear and the technical primacy of the study was laid to rest. The next stage Involved a three part pedagogical exercise: firstly, technical understanding was brought into the students' work following a design initiative which then called for technical resolution and correction. The small scale of the metamorphoses was the second part of this strategy: students adapted a passive solar or daylighting system or device taken from prototypes discovered in their literature search, to the setting with which they were dealing, without necessarily concerning themselves with its technical completeness. The third aspect of the strategy was the test of "Community": had the metamorphosis - in its entirety, in part, or in appearance - been externalized? was it contributing to the public realm or was it basically a private undertaking even when involving changes to a publicly owned setting?"
