BUILDINGS THERMAL MODELING
Journal Title: Journal of Sustainable Energy - Year 2017, Vol 8, Issue 4
Abstract
Energy consumption reduction in the buildings sector represents a socio economical, technological and environmental preoccupation which justifies advanced scientific research. These aspects promote the use of different models, such as mathematical models, thermal, electrical, analogy, etc. in order to describe the thermal behaviour of buildings and to evaluate energy consumption in buildings. In order to obtain a better durability in terms of increasing energy efficiency in buildings is useful to use analogies between thermal and electrical models and methods. This analogy is the most important objective for smart grid technologies. However, it is important to consider the relationship between all the phenomena of heat transfer, heat storage and variation in demand for cooling and heating of buildings for better energy consumption estimate. The work is focused on presenting some mathematical and thermal models of building elements and their analogies with electric circuits’ elements. As an application is presented a mathematical model (analytical) and physically in order to reproduce the behaviour of the indoor and walls temperature for a specific period of time for a heated room based on fundamental laws of thermodynamics, heat transfer and variables thermo-physical using the program Matlab.
