What is "good architecture”? Simple question, difficult answer(s). Moreover, very individual ones. We discuss here the methods of evaluation of architecture (subjective, normative, objective and intersubjective ones, perception, cognition and of architecture). We look for criteria of building - ecological quality, mentioning the quality indicators in the different fields. Qualities can be identified on build or just imagined and drafted architecture, they are present in the process of architectural design. We present here the basics of the method of evaluation of building-ecological qualities, which we have prepared with the colleagues from Technical University in Vienna. We believe that in the future complexity of the architecture can be evaluated in similar way – today it is the field of subjective architectural evaluation.
