  • Owners choice
  • 2 Entrances
  • Privacy/security good
  • Concrete system
  • Straightforward structure

Benefits
  • 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

Wall systems Cladding
  • EIFS exterior wall systems
  • Good thermal values
  • Lightweight
  • Inexpensive compared to stone panels
  • Available in many colors

Performance architecture
  • requirements that are not matched
  • computer machines room closed to the instr. labs
  • level of allowed noise for large classrooms
  • privacy of student offices
  • 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
