Ursos < Sustainability at neighborhood


For some time there are several tools that calculate the energy demands of buildings through modeling and simulation of its characteristics, the behavior of its users and climatic properties of their environment. However, the absence of urban level equivalent to not allow programs evaluated in the same way an urban plan or newly created or an existing neighborhood. To fill that gap, the Group Energy and Building of the University of Zaragoza has developed over ten years Ursos program. This team, from studies initiated with the Institute for Diversification and Saving of Energy and developed in the Renaissance European project, has evolved the software until a tool to not only assess the energy demands of heating and cooling, but urban sustainability also differentiated in three areas: energy, environment and livability. The first covers energy consumption, both calculated according to the characteristics of the buildings (with influence of shadows between them) as street lighting and generated waste collection and movement of land in urbanization, among others . Meanwhile, the environmental section covers the materials used, soil characteristics, water use, etc. Finally, from the point of view of habitability, concepts related to human welfare such as public transport or bike path, the distances to necessary services (shopping, leisure, schools) and the presence of public and wooded areas are assessed. Ursos has been included in several master’s programs because of the ease with which its use skill and speed with which concepts of energy design of buildings, urban sustainability, movement of the sun and shadows generated assimilate acquired.
