03 PERSONA TOOL
PERSONAL FOOTPRINT CATEGORIES
All personal profiles are based on an average US citizen living on or within the corridor. Between the
personas, the “Building” and “Transportation” categories of the individual’s footprint are changing
based on whether they live in a new wood construction (as-is, persona 1-4) or a highly renovated
building (persona 5) and the lifestyle options they can adopt due to the changing public realm and
development of the corridor.
Depending on which section of the corridor they live in and around, the proposed changes to the
corridor section differ the “Building,” “Water,” and “Sequestration” categories of the individual’s
footprint due to its typology. The building type typical of that section changes the available roof area
and dwelling size impacting the proportion of energy used, embodied carbon, and active roof (PV,
green, blue) benefit allotted to each person. The design of the public realm also differs between each
typology, contributing to different sequestration and renewable energy benefit allotted to each person.
The personal footprint includes consideration of seven (7) major categories that comprise a person’s
annual carbon footprint. These are:
1. Buildings: The embodied carbon of the individual’s residence is included. For the as-is case,
there is no active roof. For personas 1-5, there is an active roof that partially generates renewable
electricity with PV, partially houses an extensive green roof, and has a blue roof component to
collect rainwater to use for toilet flushing (reducing potable water use). The operational carbon
includes the individual’s residential use as well as a portion of their food/retail and office use for the
year based on LEED’s occupancy index and time use data from the US (2022).
2. Transportation: Carbon associated with the embodied and operational use of car and public
transport is included as well as the embodied carbon of the road infrastructure. The carbon
associated with flights and airmail is also included. The impact of the corridor’s public realm in
association with transportation, such as amenities and infrastructure for increased walkability, is
encapsulated through its impact on creating opportunities for lifestyle changes for the person living
on and within the impacted areas of the corridor. These lifestyle changes are further categorized
into three types: car-centric, intermediate, and person-centric. The car-centric lifestyle represents
the most similar to the as-is suburban case, while the person-centric lifestyle represents a best
case where the corridor design is highly walkable.
3. Water: Residential potable water use and wastewater is included.
4. Waste: Based on national and state specific data. Disposal is through landfill with gas collection,
flare, and a portion of electricity generation.
5. Food: Environmental impact of food based on a typical US citizen 2,000 calorie omnivore diet.
6. Other: These include two large carbon emitting components which include medical and data
storage.
7. Sequestration: the sequestration efforts in the proposal are through vegetation in the public
realm. This category includes the embodied carbon and sequestered (vegetation) or avoided (from
renewable energy generation with PV) carbon developed as part of the public realm.
