An important objective of European energy policy is to reduce energy consumption and greenhouse gas emissions. A large proportion to these contributes the building stock. There are several methodologies that are allowing review and assessment where the largest savings are stored, but each of these methods requires certain information. This work presents an overview of the currently available information sources and required information from existing methodologies in order to make calculations of energy indicators. To demonstrate the utility of information integration in this area we have made the prototype of an application that shows the aggregation of data from publicly accessible databases in Slovenia (the Real Estate Register, Building Cadastre, the Register of Spatial Units) and other required data in order to use a building typology of the IEE Tabula project. A comparison with actual measured data of energy consumption showed that the data collected in that manner allow us better analyses of the building stock. With the proposed method we are able to enlarge existing databases and use them for further studies that include sustainability criteria or energy efficiency use.

Today, in the Architecture, Engineering and Construction (AEC) sector there is a major goal to achieve sustainable buildings that are both Energy Efficient (EE) and employ Renewable Energy Sources (RES). Latest advancements in Semantic Web technology may prove instrumental in facilitating more efficient and effective knowledge exchange in this area. The goal of the present study is to contribute to these ongoing efforts by analyzing the possibilities to capture, distill and disseminate know-how among the expert AEC communities in an open way. For this purpose, a complex conceptual model, i.e. ontology based on Semantic Web standards was developed. It is shown that architects, designers, civil engineers and other professionals can use the developed ontology to study various engineering problems related to EE and RES in buildings. Moreover, the ontology could be used to create and develop an open knowledge base of engineering solutions related to energy in buildings.

Numerical formulation for computation of plastic deformations (that includes isotropic and kinematic hardening) has been derived. The formulation is based on stress resultant formulation. Several pseudo-time integration schemes for computation of internal variables are studied.
