15. Performance – architecture AEC

16. Performance – architecture AEC requirements, that are matched: -daylight for all classrooms, labs, offices -all classrooms have a views to river or mountains -privacy for offices -security for administration and computer machines room requirements that are not matched: -computer machines room closed to the instr. labs -level of allowed noise for large classrooms -privacy of student offices
