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!

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).

The numbers founded are not reliable but most of the high technology buildings such as isulated walls, windows.... are started to build from 10 to 15 years ago, so if we could find the building area in the year 2000, we could sustract that from the building area in Helsinki at the moment and get the building area which is built during these 10-15 years and they are high tec building areas with regard to 2 % renovation rate and rebuilding which is on going every year which sould be added to the total amount.

⇤--#: . 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) (type: truth; paradigms: science: attack)

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.
