We can describe the area of the building as it intersects the ground plane as its "footprint". I can describe the top of a building as having a roof area. But I need a simple, widely understood term for the total "coverage" of the building, its total "horizontal projection." In a right-angle prism, the floor plate and the roof plate have the same area. But if the prism is skewed or the building has swoops, the total area "Under the Sun" is something else.
Any suggestions will help.

The first word that came into my mind was "umbrella", but that's not completely accurate either. |

Michael, I'm not sure there is a "simple, widely understood term" for what you describe. I suggest that whatever term you eventually settle on, you'll need to describe it; and probably it can be better described graphically than with words alone. |

"Reflected Footprint", defined as the building footprint plus the reflected projection of the building beyond the footprint. This term is derived from the simple and widely understood term "reflected ceiling plan". |

"Lot coverage"? In the case of zoning codes, projections count when figuring how close to a lot line a building is. Not sure what zoning people call this. |

How about something akin to "drip line" like used to describe the full extent of above-ground coverage for a tree?

I'm with buznick - "Lot Coverage" is the term you're looking for. |

horizontal projection
umbrella
reflected footprint
lot coverage
drip line
-- great terms, almost poetic.
Lot coverage is good, but refers to a percentage of lot area, so needs refinement. Perhaps "covered lot"
In my musing, I have also thought of
sky-eye view
zenith view zone
isometric shadow
ground obscuration
bombardier view
perpendicular projection
I am a fan of Buckminster Fuller who is renown for creating precise but verbose phrases. He might have called it the projection of the minimum prism enclosing building and appurtenances extended at right angle from plane tangent to horizon.
There is a real word use in Photogrammetry that seems appropriate, "orthorectified"
But if I refer to the orthorectified perimeter of building, will anyone outside of this conversation understand me?
Keep those ideas flowing. Much appreciation for your assistance.

John Bunzick uses Lot Coverage. HUD used to have a number of different area calculations for areas and densities. I think the related term they used was Building Site Density.
It was the calculated area of the foundation at grade divided by the area of the parcel (i.e. legal description as defined by the survey)
I understand Michael is not asking about density, which both John and I are defining. So is this just "foundation area at grade"?
(Michael, on second reading, I wonder if volume of the building enters into it? Is a pyramid different than an inverted pyramid? They would have the same volume, but an obviously different foundation area at grade.) |
