Concepts and definitions
- Building
A building refers to any independent structure permanently constructed or erected on its site. It has its own entrance and contains covered space intended for different purposes, usually enclosed within outer walls or walls separating it from other structures (buildings).
Caves and other subterranean spaces which are mainly enclosed within rock or similar walls and/or which do not contain structures comparable to the interior structures of buildings proper, for example underground oil tanks, are not buildings.
Stalls, kiosks, etc. that do not contain space separated by closed walls, and transportable caravans, ships, etc. are not classified as buildings.
The building stock statistics do not include:
- free-time residences
- buildings intended for storing liquids
- buildings used only in agricultural production
- sauna buildings belonging to residential buildings
- outhouses of residential buildings
- buildings entirely controlled by foreign missions
- buildings of the Armed Forces
- air raid shelters
The data on buildings come from the Population Information System of the Population Register Centre.
- Building material
The building material refers to the material from which the vertical supporting structures of the building are mainly made. The classification is as follows:
- concrete, light concrete
- brick
- steel
- wood
- other, unknown.
- Facilities
Data on the facilities of dwellings and buildings are derived from the dwelling and building data of the Population Information System of the Population Register Centre.
Facilities in a dwelling:
- sewage
- running water
- toilet
- hot water
- washing facilities (shower, bathroom or sauna)
- sauna in the dwelling
- central or electric heating.
The data on dwelling facilities have been used in determining the standard of equipment of the dwelling.
Facilities in a building:
- electricity
- sewage
- running water
- hot water
- lift
- sauna in the building
- swimming pool
- mechanical ventilation
- air raid shelter.
- Gross floor area
The gross floor area of a building comprises the floor areas of the different storeys and the area of attic or basement storeys in which there are dwelling or working rooms or other space conforming to the principal intended use of the building.
The gross floor area is the horizontal area enclosed by the outer surfaces of the walls of the storeys or their imagined continuation for openings and decorations on the surface of the outer walls.
- Heating fuel/ source of heat
Heating fuel or source of heat refers to the main fuel or energy source used in heating a building. There are also data on the heating fuel of dwellings. Data on the heating fuel have been obtained from the Population Information System, which receives them from municipal building supervision authorities.
Information about change in heating fuel is mainly transmitted to the Population Information System only if such alterations have been done to a building which require a building permit.
The classification is as follows:
- district heating
- oil
- gas
- coal
- electricity
- wood
- peat
- ground heating
- other, unknown
- Heating system
Heating system refers to the main method of heating used in the heating of a building. There are also data on the heating fuel of dwellings. Data on the heating fuel have been obtained from the Population Information System, which receives them from municipal building supervision authorities by way of building project notices. Information about change in the heating system is only transmitted to the Population Information System if such alterations have been done to a building which require a building permit.
The classification is as follows:
- central heating, water
- central heating, air
- direct electric heating
- stove heating
- no fixed heating installation
- unknown.
In a water central heating system, the building is heated with circulating water, and in an air central heating system with circulating air. In direct electric heating the building is heated with the aid of a fixed radiator, etc. connected directly to the electricity network.
In stove heating, heating takes place by burning wood or other fuels in a fireplace (stove) that stores heat. Stove heating also includes electric heating reservoirs, separate fixed oil heaters and heatpreserving fireplaces. Stoves used for heating saunas are not regarded as heating equipment.- Intended use of building
The intended use of a building is determined according to the purpose for which the largest part of the gross floor area of the building is used. The categories are as follows:
- residential buildings
- commercial buildings
- office buildings
- transport and communications buildings
- health care and social services buildings
- assembly buildings
- educational buildings
- industrial buildings
- warehouses
- fire fighting and rescue services buildings
- other buildings.
The classification of the intended use of buildings is given in Statistics Finland's Handbook Classification of Buildings 1994. Not all the classes in the building classification are included in the Statitics Finland's building stock.
- Network connection
The following network connections are identified for a building:
- sewage
- running water
- electricity
- natural gas.
- Number of storeys
The number of storeys in a building consists of all storeys that are primarily above ground level and in which there are habitable rooms or office space or other space conforming to the intended use of the building. If the number of storeys varies in different parts of the building, the number usually refers to the largest number of storeys in the building.
For buildings completed after 1980, the number of storeys is expressed as an average number that takes into account the whole building if the share of the gross floor area of a certain storey out of the gross floor area of the main storeys is very small. For instance, if a large industrial unit is mainly a one-storey building, but office space is located on three storeys, then the number of storeys is given as one.
- Residential block of flats
A house with at least three dwellings of which at least two are on top of each other.
- Sub-area (of municipality)
Municipal sub-areas are formed of operationally functional wholes defined by the municipality itself, which are the basis of the municipality's regional planning and monitoring. Statistics Finland is responsible for digitising new sub-area boundaries and for maintaining name files. Municipalities have the opportunity to check their sub-area division once a year.
The division into sub-areas is a hierarchical three-level classification which has a 1-digit major area level, a 2-digit statistical area level and a 3-digit small area level. Sub-areas are numbered consecutively using these three hierarchical levels. The 6-digit sub-area code is bound to the 3-digit municipality code, so the sub-area code consists of a total of nine characters.
- Type of building
Residential buildings are classified according to type of building as follows:
- Detached houses: residential buildings containing 1 to 2 dwellings, including semi-detached houses and other comparable detached residential buildings (e.g. permanently occupied free-time residences)
- Terraced houses: residential buildings with at least three adjoining dwellings
- Blocks of flats: residential buildings of at least three dwellings in which at least two dwellings are located on top of each other and which do not belong to the previous categories
- Other buildings: also includes buildings whose type is unknown.
- Type of ownership of building
Buildings are divided into the following categories by tenure status:
- private person/ death estate
- housing corporation or co-operative
- real estate corporation
- private company
- company controlled by the State or municipality
- State or municipal corporation
- bank or insurance company
- municipality
- State
- social security fund
- religious community, foundation, party, etc.
- other or unknown.
- Year of construction
The year of construction refers to the year in which the building was completed and was ready for use. If the building was completed prior to 1980, the year of renovation may have been entered as the year of construction.
