The orientation of buildings and its impact on the internal environment has been studied for long time using different methods and softwares.
The case study and the application used are interesting as they add extra information to what is known from classical tools. 
The use of frontal abacus projection was used for long time and then replaced by the orthogonal projections which contribute to a better understanding and add more clarity, may be you can use them instead.
The graphs generated by Ecotec, could be presented in larger formats for a better and clear reading.
The internal environment is highly influenced by 3 components (the external environment conditions, the construction specifications and the internal layout), this second component was not taken into account as it should.
