Rethinking Logistics

Green-core anchoring of mixed uses

Metric · verified

A measurable indicator (students often call it a KPI) used as evidence for a design decision.

Unit% of entrances (or frontage length)
How it is calculatedBuilding entrances (or ground-floor frontage length) of all uses within a set walking distance (e.g. 100 m) of a shared green spine ÷ total entrances (or frontage length).

What it measures

Whether the different uses of a mixed-use logistics development are tied together by a shared, connected green space, rather than just sitting next to each other. Companion to Mixed-use ratio: that one measures how much mix there is, this one measures whether nature holds the mix together.

Calculation

  1. Define the shared green spine or core (continuous, publicly accessible green space).
  2. Map entrances (or active ground-floor frontage) of every use — logistics, offices, housing, retail, hotel, community.
  3. Measure walking distance from each entrance to the spine.
  4. Result = entrances (or frontage length) within the threshold distance ÷ total. Report per use type as well, to check that no use is left out.

Can be done in Grasshopper with shortest-path walking distances on the pedestrian network.

Franziska Meisel (Henning Larsen), lecture Nature positive by design, Q&A on the Sugar Valley master plan (former Siemens site, Munich): “a green spine in the middle that really is supporting all the different function. There’s a hotel, housing, offices, very mixed-use, but it’s really all bound to this kind of green space in the middle.”
