Necessary input data

Before you can start using SENIB

Before you can perform any calculations with SENIB, then you first need to know some basic facts about the house, such as its size and room height on each floor. If the house is somewhat newly built you could be so lucky that the U-values of the house are specified in the blueprints. Otherwise you need to calculate the U-values by knowing the structure of the exterior walls and the roof, i.e. the thickness of the layers they are composed of and their insulation capacity. You can’t calculate U-values with SENIB.

What you can do now

Before you have all the basic facts about the house there is one important thing you can start with right now and that is to start writing down all meter readings, e.g. for district heating, oil or pellets but also meter readings for property electricity, cold water and hot water usage. These meter readings can be taken at your convenience and does not need to be at the end of each month for example. Preferably they should be taken as late as possible in the evening or at least more or less at the same hour each time. However, it is very important that the meter readings are taken if any energy source is changed. For example, if the house is heated with oil during the winter but with electricity in the summer. Then all meter readings should be taken when the oil burner is turned off for the summer and when it's turned back on for the winter.
