Site conditions AEC

Winter Decision Matrix A E C Benefits Draw - backs Owner’s choice 2 Entrances Privacy/security good Concrete system Straightforward structure Spiral stairs Concrete frame & slab Better MEP & floor depth Not risky for A Roof truss & MEP intake Stream threats Skylight leaking Extended footprint Deep floor beams & MEP Lack of vertical mech. path space $2.7 Million 6/01/16 $3.4 Million 5/12/16

Functional spaces and relationship AEC

3d view – design concept...water is flowing among stones......sunlight - collected like rain in a lake in the mountains... AEC

Key elements of design instr. labs student offices, large meeting space normal student offices seminar rooms auditorium entrance hall AEC layout floor #2 south-north section with sunlight study

Layouts (schematic view) mechanical computer storage restrooms auditorium large classr. small classr. instr. labs student - offices seminar r. faculty off. secretaries chair‘s off. senior admin AEC basement floor #1 floor #2 floor #3

Entrance the fly brake box builds a relationship between the road and the building AEC

Sight lines AEC floor #1 line: road – entrance – auditorium  leads people into the building sight lines to stairs circulation

Floor #1 entrance hall with fly brake box (1.1, 1.0) auditorium (1.5) large classrooms (1.4, 1.6) small classrooms (1.7, 1.8) restrooms (1.2, 1.3) AEC

Floor #2 pbl spaces with seminar rooms, student offices, round table space ( ) greenhouse space (2.23) instructional labs (2.6, 2.24) small classrooms (2.28, 2.30) faculty offices (2.4, 2.5, 2.26, 2.27) storage (2.25) restrooms (2.2, 2.3) AEC

Floor #3 administration ( ) faculty offices( ) storage (3.18) gallery (3.10) faculty lounge (3.6) restrooms(3.2, 3.3) hallway (3.1, 3.22) AEC

Performance – architecture AEC

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
