Building Technology Division
General
- Don't tweak your designs if you have extra time - you will run out of time, most likely in the middle of tweaking.
- computer does not grade on quality of design, only check against code/program data

Roof Design

Scope:
- Upper and lower roof: Calc. clng. ht. + structure thickness + clerestory
- Clerestory requirements
- Roof plan slope requirements
- Flashing at roof to wall and roof to chimney intersections
- Crickets at Chimney if required
- Skylights (per program)
- Gutters outside of roof edge
- Downspouts, avoid windows, doors, show at wall area only, provide one each end at long lengths.
o also provide at high roof to low roof if applicable
o watch out for porch and columns
- HVAC, locate per program requirements
- Exhaust vent, locate per program (not in wall)
- Plumbing vent stack, per program (back to back bathrooms can share)

Fatal Errors:
- Missing elements
- Clerestory location
- Overlapping roof planes (use check tool)
- Improper roof slopes (use least allowed per program)
- Natural light requirements for rooms without windows
- Highest ridge height
- complicated roof: keep it simple stupid (not grading on design)
- Poor HVAC location
- Improper roof elevations: See calc note above
- Downspout locations: see notes above
- Too much volume: minimize differences between clng heights and roof elevations
- Surfaces sloped in wrong direction
- Crickets per program

Personal Notes:
- Make an itemized checklist from the program
- Draw roof plans and all other elements
- When you think you are finished, run through the checklist and verify all is provided
o and verify that all is provided per program, slopes, skylights, etc.
