Assignment 4: Accessibility and sustainability

Issued Sept. 23, 2017
Due Sept. 30, 2017 (in class)

Part I: Accessibility

Design a handicapped ramp in room 240 E. Sibley Hall connecting the room with the landing leading to Sibley Dome. You may either leave the existing stair in place, or design a new stair.

The ramp and stair must be placed within the yellow-toned area indicated on the floor plan below (click on image to enlarge):

Room 240 E. Sibley Hall part plan

You may assume that the metal and glass office wall that is shown as a dotted line in the plan has been removed.

Draw a part plan and a section (at 1/4" = 1'-0" scale) that shows the ramp. Draw guards and handrails in both the plan and section (dimensioning information for handrails and guards can be found in Chapter 10 of the 2015 International Building Code (IBC), Sections 1014 and 1015. Also refer to the section on handrails and landings for accessible ramps provided by the United States Access Board. Show all critical plan dimensions of the ramps and landings, as well as all critical vertical dimensions (e.g., of guards, handrails, and ramp elevations) and include notations that identify the typical elements (guards, handrails, etc.).

For "drafting" guidelines, see these outline notes on lines and dimensions and notations For more detailed recommendations on CAD Standards (plans, elevations, dimensions, notations, etc.), see links to National CAD Standard, latest version, as enumerated in the readings for week 5.

Part II: Sustainability

Based on Cornell's final USGBC review report [PDF]* for Milstein Hall, choose what you think is the most important credit that was not achieved by Milstein Hall (excluding energy performance, EA Credit 1) and that would have made Milstein Hall a more sustainable building. In one or two paragraphs, describe why this credit is important, and how the requirements for that credit could have been achieved. In other words, describe specifically how the design of Milstein Hall would need to change in order to accommodate the new credit. See my Summary and critique of LEED 2.2 New Construction Reference Guide for a description of all the LEED credits that were available when Milstein Hall was built (later versions of LEED can be found here). You may also refer to Table 1 in my critique of Milstein Hall's sustainable characteristics for a subjective and unofficial tabulation of LEED credits.

If the Milstein Hall PDF doesn't open properly in your web browser, try downloading it and opening it in Adobe Acrobat Pro.


Submit on three sheets of 11 x 17 inch paper, oriented horizontally (one for the plan; one for the elevation or section; and one for the description of how a missing sustainable feature for Milstein Hall could have been provided).

You are encouraged to work in groups consisting of 2 to 6 students. To facilitate NAAB documentation, each group should consist of either undergraduate or graduate students, but not both.
