In the case where calculating the effect of Energy Saving Control of the equipment for becoming object, in order to calculate the effect, examine
Effect computing interval of the setting such as 1 year to a certain degree is considered, by the energy input of 1 year for implementing Energy Saving Control and no reality
Apply the method that the energy input of the whole of last year of Energy Saving Control is compared.However, since annual temperature on average is different, and exist
Warm winter or heat etc., it is possible to be easily envisioned, it is difficult to which regarding these effect computing intervals as both sides in 1 year is all
Identical external condition.Also, even if the effect computing interval is being set as one month, the energy of this month of Energy Saving Control will be implemented
In the case that the energy input of consumption and the last month without implementing Energy Saving Control are compared, due to there are the transition in season,
It is difficult to all regarding both sides into identical external condition as.
On the other hand, it is also considered that using amendment, approximation, simulation calculates the side of the energy-saving effect under identical external condition
Method.However, structure do not introduce error as far as possible as high-precision innovation representation or approximate expression need in itself it is huge
Labour, and be unpractical for complicated object.Also, it is considered that for example using the actual achievement data creating in cold summer

The time span that energy effect can show, will by piecemeal be divided into multiple short sections, selects these areas in the effect computing interval
Between in some section, there are many situation for being regarded as identical external condition.
Present invention contemplates that such the reason for calculating the error generated during energy-saving effect, is that the effect compared calculates
During external condition difference and existing select the segmentation effect computing interval it is interior for multiple sections set just
Regard the situation of identical external condition as.According to this, to the external condition in next section successively pre- measurement equipment, based on the prediction knot
