=== Data ===
This part contains the data needed for calculations about the building stock in Helsinki. It shows the different building and heating types in Helsinki, and how much and what kind of renovations are done for the existing building stock in a year, including how much and how old building stock is demolished. This data is used in further calculations in the model.


==== Building stock ====
There is also some other important data that wasn't used in the model's calculations. These include more accurate renovation statistics for residential buildings, U-value changes for renovations and thermal transmittance of different parts of residential buildings. This data is found under [[Building stock in Helsinki#Data not used|Data not used]].

For residential buildings (classes A and B) the classification is kept more detailed than for other buildings. This is because residential buildings are the biggest energy consumers in Helsinki and different classes of residential buildings are examined separately.<br />
Reference for the classification: http://www.stat.fi/meta/luokitukset/rakennus/001-1994/koko_luokitus.html

;Notes:
* Estimates were based on {{#l:Siemens City Performance toolin seuraava kokous 2.2.pdf}} and some derived calculations on {{#l:BUILDING STOCK CALCULATION 2015.xlsx}}.
* How to get the numbers for the ''baseline floor area'' for residential, public, industrial and other: Residential floor area was named as residential together, public by summing the floor area of health care, education  and common  buildings, industrial buildings were as such and other buildings comprise of business, traffic, office and storage buildings.
* Ref. Helsinki master plan for 2050: there are 860 000 citizens living in Helsinki  (ref. www.yleiskaava.fi, visio2050);  Residental buildings => fast growth
* Prediction of citizen number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).
* Helsinki’s climate policy: 30% reduction in emissions:  In 2010 the proportion of jobs in services and public sectors was 94%, and in industry 6%.  In 2020 the proportion of jobs in services and public sectors is estimated to be 96%, and in industry 4%. Public and other buildings => between fast growth option and basic option,  Industry=> Basic option
* Prediction of job number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).

==== Construction and demolition ====
=== Construction and demolition ===


It is assumed that construction equals 2 % of the existing building stock per year. Energy efficiency comes from [[Energy use of buildings]]. It is assumed that no demolition occurs.
It is assumed that construction occurs at a constant rate so that there is an increase of 42% in 2050 compared to 2013. Energy efficiency comes from [[Energy use of buildings]].

=== Heating type conversion ===
 
The fraction of heating types in the building stock reflects the situation at the moment of construction and not currently. The heating type conversion corrects this by changing a fraction of heating methods to a different one at different timepoints. Cumulative fraction, other timepoints will be interpolated.

;Notes:
* Estimates were based on {{#l:Siemens City Performance toolin seuraava kokous 2.2.pdf}} and some derived calculations on {{#l:BUILDING STOCK CALCULATION 2015.xlsx}}.
* How to get the numbers for the ''baseline floor area'' for residential, public, industrial and other: Residential floor area was named as residential together, public by summing the floor area of health care, education  and common  buildings, industrial buildings were as such and other buildings comprise of business, traffic, office and storage buildings.
* Ref. Helsinki master plan for 2050: there are 860 000 citizens living in Helsinki  (ref. www.yleiskaava.fi, visio2050);  Residental buildings => fast growth
* Prediction of citizen number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).
* Helsinki’s climate policy: 30% reduction in emissions:  In 2010 the proportion of jobs in services and public sectors was 94%, and in industry 6%.  In 2020 the proportion of jobs in services and public sectors is estimated to be 96%, and in industry 4%. Public and other buildings => between fast growth option and basic option,  Industry=> Basic option
* Prediction of job number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).
* {{#l:Tables one and two.pdf}} The presentation of Tables 1 and 2
''Technical 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 building types 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.
* There was a problem with missing data. There is more than 400000 m^2 floor area that is missing; this is estimated from total area that is available for these buildings. For other buildings, there is more than 400000 m^2 total area missing from buildings where floor area is given. See statistical analysis [http://en.opasnet.org/en-opwiki/index.php?title=Special:RTools&id=026ekUv81jP0A6rI]. This was corrected by inputation so that is floor area was missing, 0.8*total_area was used instead [http://en.opasnet.org/en-opwiki/index.php?title=Special:RTools&id=oE7UXNQt3Izdo4tE].

During Decision analysis and risk management 2015 course, this page was used to collect student contributions. To see them, look at an archived version. The page has since been updated for its main use. Data in the archived tables was moved: Table 2. Energy parametres of buildings, Table 4. Energy sinks, Table 5. Changes in energy efficiency, Table 6. Important energy parametres. Tables 3, 7, and 8 did not contain data and were removed.


Question

What is the building stock in Helsinki and its projected future?

Answer

+ Show code

Rationale

This part contains the data needed for calculations about the building stock in Helsinki. It shows the different building and heating types in Helsinki, and how much and what kind of renovations are done for the existing building stock in a year, including how much and how old building stock is demolished. This data is used in further calculations in the model.

There is also some other important data that wasn't used in the model's calculations. These include more accurate renovation statistics for residential buildings, U-value changes for renovations and thermal transmittance of different parts of residential buildings. This data is found under Data not used.

Building stock

These tables are based on FACTA database classifications and their interpretation for assessments. This data is used for modelling. The data is large and can be seen from the Opasnet Base. Technical parts on this page are hidden for readability. Building types should match Energy use of buildings#Baseline energy consumption.

Construction and demolition

It is assumed that construction occurs at a constant rate so that there is an increase of 42% in 2050 compared to 2013. Energy efficiency comes from Energy use of buildings.

Heating type conversion

The fraction of heating types in the building stock reflects the situation at the moment of construction and not currently. The heating type conversion corrects this by changing a fraction of heating methods to a different one at different timepoints. Cumulative fraction, other timepoints will be interpolated.

Data not used

This contains data that was not used in the model's calculations. This includes renovation rates, the rates of heat flowing out of buildings and total floor areas of multiple types of buildings in Helsinki. The floor area data is also found in the background data of this page, which was used in the model.

Notes
  • Estimates were based on Siemens City Performance toolin seuraava kokous 2.2 and some derived calculations on BUILDING STOCK CALCULATION 2015.
  • How to get the numbers for the baseline floor area for residential, public, industrial and other: Residential floor area was named as residential together, public by summing the floor area of health care, education and common buildings, industrial buildings were as such and other buildings comprise of business, traffic, office and storage buildings.
  • Ref. Helsinki master plan for 2050: there are 860 000 citizens living in Helsinki (ref. www.yleiskaava.fi, visio2050); Residental buildings => fast growth
  • Prediction of citizen number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).
  • Helsinki’s climate policy: 30% reduction in emissions: In 2010 the proportion of jobs in services and public sectors was 94%, and in industry 6%. In 2020 the proportion of jobs in services and public sectors is estimated to be 96%, and in industry 4%. Public and other buildings => between fast growth option and basic option, Industry=> Basic option
  • Prediction of job number in Helsinki in 2020, 2030, 2040 and 2050 was used for calculations (ref. Helsingin 30% päästövähennysselvitys).
  • Tables one and two The presentation of Tables 1 and 2


Technical 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 building types 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.
  • There was a problem with missing data. There is more than 400000 m^2 floor area that is missing; this is estimated from total area that is available for these buildings. For other buildings, there is more than 400000 m^2 total area missing from buildings where floor area is given. See statistical analysis [1]. This was corrected by inputation so that is floor area was missing, 0.8*total_area was used instead [2].
Renovations per year made in residental buildings owned by Helsinki city, by construction year of the buildings.[1]
