The amount of energy needed to heat a building depends on a number of factors
There are several factors related to the building as such. E.g., how it was designed, built, the amount and type of insulation, what kind of energy source that is used, how it is distributed and so on… The list is long, and it is not sufficient only to look at the structure of the building, it also depends on who and how many people that lives in it, what habits they have, demographics etc.
Indoor and outdoor temperature
In order to regulate the indoor climate to the desired temperature there is a relation between the outdoor temperature and the energy systems feed temperature (the temperature of the water inside your radiators). The relation is referred to as the building heat curve. It is a number of parameters that ideally should be based on all the parameters above
An impossible mission
It is a very complex task to calculate this and set the parameters correctly and it is impossible without tools. It requires a thorough and methodical approach and a lot of measurement data. It is not magic and in theory it would be possible to do manually but it is not practically possible. Nrlyze automates this process and identifies the ideal parameter setup fast and easy.
