Question

What is the building stock in Helsinki?

Answer

Rationale

Data

Building stock

The structures of the tables are based on CyPT Excel file N:\YMAL\Projects\ilmastotiekartta\Helsinki Data Input Template - Building Data.xlsx.

Table 1. Effective floor area of buildings by building type.

Type of data:

Average, City
Example, city
Average, city close by
Example, city close by
Average, national
Example, country

Quality of data

Statistics
Extrapolated
Calculated from statistics
Calculated from stat. inc. assumptions

Effective floor area of buildings(m2)
Obs	Building	Baseline	2020	2025	2050	Year of baseline	Type of data	Quality	Description
1	Residential
2	Public
3	Industrial
4	Other

Notes: Sheet 4_Input Buildings (Area Demand). Priority 1. Auxiliaries PPT. Absolute increase/decrease rate will be based on the inhabitants projected in time.; This is another list that was considered but rejected as too complex: Residential buildings, Government & public administration buildings, Commercial offices buildings, Data centers buildings, Education and K12 and universitiy buildings, Hospitals and healthcare buildings, Hotels and hospitality and leisure buildings, Exhibitions and fairs and halls buildings, Retail and stores and shops buildings, Warehouses & shopping mall buildings, Industrial buildings, Non residential buildings unspecified
