Question

What is the building stock in Helsinki?

Important reminder: Always include the references to the tables: where did you get the value and how. A value without the reference is useless because it's not possible for others to track how it was derived.

If you couldn't find a value, write down where you tried to search. This is important because then nobody else needs to search the same sources again for nothing. Thank you!

• Heating consumption of buildings

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

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

Notes

Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 1. Auxiliaries PPT.

Energy demand

Table 3. Total energy demand by energy type and building type.

Notes

Heating includes warm water. Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 1. Auxiliaries PPT.

⇤# : The problem with your table is that you have changed the columns. You cannot do that, because the original classification is what we use in the model. Instead, you have to extrapolate from the existing numbers to those classes needed in the model. --Jouni (talk) 06:45, 29 April 2015 (UTC)

--# : Also include references and links so that the reader can go back to the original data and see where the numbers came from. --Jouni (talk) 06:45, 29 April 2015 (UTC)

Notes

Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 1. Auxiliaries: see table.

Data from Climate policies Helsinki additional data

We went through the data mentioned above and also the files given in "Climate policies Helsinki data" Climate policies Helsinki data but could not find the data for cooling, heating:infiltration, heating:other, heating:warm water:other and electricity:ventilation:resindential.

Total estimated amount of energy needed for cooling 23504480 kWh/a (whole Helsinki). Based on http://www.energiatehokashelsinki.fi/energiankulutus/Helsinki 14332 GWh/a for housing (total energy demand minus traffic 18 % [1] ) and http://www.korjaustieto.fi/pientalot/pientalojen-energiatehokkuus/energiatehokkuus-pientaloissa/pientalon-energiankulutus-ja-paastot.html 2 % of total energy demand of housing used for cooling. Total floor area of Helsinki needed (table 1).

Table 5. Changes in energy efficiency of different energy sinks.

Notes

Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 3. Auxiliaries Excel.

Estimated 3 % of houses renovated/year and 20 % increase in energy efficiency when renovated. [2] Data apart from 0.6% values from Climate policies Helsinki additional data

The presentation about tables 4 and 5 PresentationHW9

Table 6. Important energy parameters.

Notes

Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 3. Auxiliaries: see table.

Lighting

Tables 7-8. Run times and shares of lamps by lamp type and building type.

Notes

Sheets 5_Input Residential, 6.0_Input Non Residential, 6.2_Input Public Admin. Priority 3. Auxiliaries Excel.

Other

Sheet 4_Input Buildings (Area Demand). Priority 1. Auxiliaries PPT. Nice to have specific factor otherwise we adapt standard data or other studies.
