The environmental monitoring of sunspaces, not only the measurements within them relative to rooms behind, but how the sunspaces were designed in terms of their ventilation to the outside and through to the interior, have given us some insight with this new research. This includes how the users engage with manual controls at their disposal and what uses they make of the sunspaces. The measurements and other information should give us some idea as to whether they save energy (as a solar enhanced, edge-insulating buffer, and/or a solar-ventilation-preheat source) and how they function as an amenity (e.g. relaxation, clothes drying).
