LabVIEW based mathematical model of building’s heat consumption with non-stationary processes

In this article, the issue of non-stationary processes heat consumption by public buildings for the energy efficiency analysis in heating buildings is being considered. It is justified that the most suitable parameter for adapting the model to the specific building’s conditions is the total heat capacity of everything that is inside the building.

As a developed model adaptation’s result there are empirical dependence of total heat capacity has been established for schools. The developed model was used for building’s heating simulation with a cyclically changing load in order to establish the possibility to saving the energy.

After passing the preparatory adaptation, the sufficient correspondence of numerical experiments and the practical data on measurement of temperatures are justified. The model was solved using the LabVIEW programming environment.

The model is confirmed for schools in Donetsk, for each school, the number of experiments is equal to the number of information measurement days, in non-stationary thermal conditions.

This model is a part of dissertation work.
