Improving building energy efficiency has become a necessity in construction industry over the last few years. Building Information Modeling (BIM) methodology is a very powerful option to achieve this goal in which the energy demand reduction can be considered in early stage design. Nevertheless, most of building energy simulation software recognized by Spanish government is not integrated in BIM. In consequences, external software is necessary to be used in order to achieve this aim. This process significantly increases the time and computational cost because the interoperability between BIM modelling software and energy analysis software causes several problems during the information exchange. For the purpose of checking compliance in early stage design, this research has developed a new tool using BIM methodology to check the thermal parameters of vertical building envelope, as set out in the Spanish building regulation. In order to achieve this aim, it has been developed using Python programming language integrated in Dynamo and Autodesk Revit software. This technique provides a set of algorithms of thermal transmittances and compares the results with the established values. All the results are showed in a graphical display and reported as numerical data set schedule. This paper reports the experimental results using a single family detached house in which the parameters of the building envelope are managed in early stage design.
