[blank_start]Isolated solar gain[blank_end]-functions of space
1. [blank_start]buffer space[blank_end]
-intermediate [blank_start]space[blank_end] between [blank_start]inside[blank_end] and [blank_start]outside[blank_end]
-[blank_start]adding another layer[blank_end] to buildings [blank_start]envelope[blank_end], [blank_start]thermal buffer[blank_end]
-[blank_start]shelter building envelope[blank_end] from wind chill, rain. more important in northern wind exposed locations
2. [blank_start]pre-heated ventilation[blank_end]
- [blank_start]openable vents[blank_end] in [blank_start]walls[blank_end] at [blank_start]top of sunspace[blank_end] to allow [blank_start]warm air flow[blank_end] in [blank_start]adjoining spaces[blank_end]
-[blank_start]cool air returned[blank_end] from [blank_start]living spaces via lower vents[blank_end] and [blank_start]heated[blank_end] as part of [blank_start]convective loop[blank_end], called [blank_start]thermosyphonic system[blank_end]
-[blank_start]mechanical ventilation[blank_end] [blank_start]increase penetration of pre-heated air[blank_end] deeper into [blank_start]adjoining rooms[blank_end]
3. [blank_start]thermal mass/ storage wall[blank_end]
- [blank_start]day warm air[blank_end] comes through [blank_start]vents[blank_end] to [blank_start]heat up space[blank_end]
-[blank_start]night[blank_end] when the air gets cold [blank_start]vents are closed[blank_end] and [blank_start]heat is transferred[blank_end] to [blank_start]living spaces[blank_end] through [blank_start]thermal storage wall[blank_end] separating the sunsapce from living space.
