RADTHERM Heat Transfer Simulator

Our environment is complex and diverse, making it difficult to understand its many functions and relationships. In order to interpret both the human and environmental impacts on the natural system, analytical models are used.

A model is a theoretical, usually mathematical, representation of a system or a complex reality. Models are created to facilitate understanding of phenomena that are inaccessible by direct experimentation, and to study their behaviours. Models are able to predict outcomes to problems by selecting specific factors, interpreting their functional relationships, and using computer software to perform mathematical calculations.

The simulation, according to Shannon & Johannes (1976), is a process of designing and developing a model from a real system to carry out experiments with it, whose purpose is to understand the behaviour of the system or to evaluate new strategies for the operation of the system.

BCNecología incorporates simulations into their methodologies as simulators are effective tools in the decision making process. By applying a simulation, the outcomes are much more definitive than trying to perform comprehensive field work, as the simulator considers the randomness of natural systems. Moreover, since simulations are mathematical models, they can be modified at any time.

During the creation of simulators for physical and biological systems, it is important for BCNecologia to apply not only one research strategy, but many, to effectively answer their research problems. This approach of combining research techniques is called transdisciplinarity, and is a fundamental procedure in the creation of simulation models within the urban environment. BCNecologia uses simulations for many purposes such as to simulate road networks and improve the fluidity of certain areas; to calculate the emissions of a transport network; and to estimate the energy or water required for the construction and maintenance of a building.

BCNecologia has developed four simulators for each urban element (waste, water and air) listed below:

- Information Systems and Urban Modelling (Sistema de Información y Modelización Urbana)

SIMUR: Information Systems and Urban Waste Model (Sistema de Información y Modelización Urbana de Residuos)

- SIMU-A: Information Systems and Simulation for Urban Water Use (Sistema de Información y Simulación Urbana del Agua)

- SIMU-CA: Information Systems and Simulation for Air Quality (Sistema de Información y Simulación Urbana de la Calidad del Aire)
