Scope
Outdoors temperature is bound to need for heating. The colder it is the more heating is needed. In larger scale outdoor temperature is dependant to earth’s cycle and weather, locally weather is dependant to geometric factors (lakes, large plants, mountains and such). Outdoors temperature changes geometrically also, but in Helsinki Metropolitan Area geometrical temperature variety is not significant. Momentarily there can be a few degrees changes in Helsinki Metropolitan area, but in the long term area can be assumed have same temperature. In Helsinki Metropolitan Area biggest changes in outdoor are caused from weather, which affects difference between yearly temperatures. For assessment of district heating, demand for heating is needed. Because tight relevance between outdoor temperature and need for heating, it is good to evaluate how will outdoor temperature variate.
Purpose is to find what kind of relation outdoor temperature and district heating need has. For this demand for heating and outdoor temperatures are evaluated.
