Glossary

Coordinates refers to the coordinates of the center of the building provided as latitude and longitude using the EPSG:4326 reference system.

Footprint source refers to the source the building footprint was obtained from:

• Google refers to Google's V3 Open Buildings
• Microsoft refers to Microsoft's Building Footprints
• OSM refers to OpenStreetMap

In case the building footprint was obtained from Google's V3 Open Buildings the confidence of their model is provided.

Building footprints are classified into residential, non-residential and industrial indicating their use based on our methodology, which relies on the following sources:

• Buildings which are associated with OSM buildings are classified based on the available OSM information, in which case the source is OSM Derived
• Certain buildings are classified based on credible information provided to OBI which is indicated by OSM Derived
• Most buildings with less than 20 square meters of area are considered residential by default, indicated by source area
• For the rest of the buildings, their types are determined by one of the machine learning models created for OBI, in which case Classification Source provides the name of the model and its confidence is provided for its choice.

Urban areas are searched by a machine learning model specialized in finding areas, which are possibly informal. Areas find by the model are annotated as Informal and the model's confidence is provided, the rest of urban areas are annotated as Formal and for such areas, which are less urbanized and therefore the model is not executed are annotated by the text Not Applicable and are considered formal for visualization purposes.

The height of the building is provided in meters as well as in number of floors. The first floor is assumed to be 4.5 meters tall to accommodate higher basements or other elevation of the building, all other floors are assumed to be 3 meters tall.

The perimeter of the building, i.e., the total length of the outer walls of the building given in meters.

The number of outer walls (faces) of the building.

Roof area refers to the area of the building when viewed from top given in square meters.

Gross floor area is the total of footprint areas of each floor on the building. Computed as footprint area times the amount of floors for the building provided as square meters.

GHS-SMOD refers to degree of urbanization as defined and categorized by Global Human Settlement Layer.

The elevation of ground on which the building was constructed given in meters.

The amount of buildings within a 100 meter square centered around the building in question.

The total volume of buildings averaged within a 100 meter square centered around the building in question given in m³/m².

The facade density withing a 100 meter square centered around the building in question.

Estimated inhabitance of residential buildings.

The name of the closest major hospital for the building using ground communication (roads, streets, sidewalks, etc.). The driving distance and walking distance is provided for the hospital both in kilometers and travel time.

The name of the closest health facility of any kind (dentists excluded) for the building using ground communication (roads, streets, sidewalks, etc.). The driving distance and walking distance is provided for the hospital both in kilometers and travel time.

The distance to the closest significant forest or park in kilometers. The area of the greenery is also provided in hectares.

The distance to the closest permanent water body in kilometers. The surface area of the water body is also provided in hectares.

Distance to the closest road of any kind given in kilometers.

Distance to the closest major road given in kilometers.

Open Building Insights provides the amount of dangerously hot days from the past year, broken down into the following categories as defined by Humidex:

• Extreme Danger - A day with a highest temperature over 46 Celsius degrees
• Danger - A day with a highest temperature between 38 and 46 Celsius degrees
• Extreme Caution - A day with a highest temperature between 29 and 38 Celsius degrees

The estimated area on the roof of the building suitable to install solar panels given in square meters.

The estimated capacity in kWp and generation over the year in kWh/year under the assumption, that the suitable area is covered by solar panels.

Estimated installation cost of solar panels to cover the suitable roof area in dollars.

The estimated mean likelihood that a building of interest is connected to the electric grid.

A mean-point estimate of a modeled distribution curve of monthly electricity consumption for a building, assuming a grid-quality connection is provided, given in kWh.
