Can I use Revit to document this credit?
You can use the Insight plugin in Revit 2017 to document this credit. The plugin has automated settings for Options 1 and 2.
A general tutorial for Insight can be found here: https://forums.autodesk.com/autodesk/attachments/autodesk/19/1006/2/insight-lighting-analysis-help.pdf
The Reality of Rainwater in LEED v4 (a Green Roof May Not Help You)
LEED should reward urban projects for vegetation and green infrastructure, but it seems to have lost sight of this goal.
by Joshua Radoff
When LEED v4 BD+C was released, there were a handful of improvements that I was really excited about: the new interior lighting credit, better daylight metrics, transit points based on number of trips, and envelope and monitoring-based commissioning, to name a few.
ASHRAE 90.1 Baseline Fan Power Calculator
This spreadsheet, provided here by 7group, can be used to calculate the fan volume and fan power for Appendix G models submitted for Minimum Energy Performance (EAp2) and Optimize Energy Performance (EAc2). Tabs are included to cover five versions of ASHRAE 90.1 Appendix G methodologies, from 2004 through 2016.

If remediation has occurred on the site in the past, outside of the LEED project scope, would it achieve this credit?
Documentation showing that the remediation occurred and that it was required by the local, state, or national authority with jurisdiction would demonstrate compliance with the requirements of Option 3.
For an international project, what if a local equivalent for identifying sensitive habitat cannot be determined?
You can review the International Union for Conservation of Nature Red List (iucnredlist.org) to determine if the project area provides habitat for any endangered species. Additionally, you might enlist a local biologist or ecologist to conduct a survey of the area.
How is “previously developed land” defined by LEED?
LEED defines “previously developed land” as any land that has been “altered by paving, construction, and/or land use that would typically have required regulatory permitting to have been initiated.”
Land that has not been altered by clearing or filling, agricultural or forestry use, or is a preserved natural area is not considered “previously developed.”
If 75% or more of the project site is “previously developed land,” it is considered a “previously developed site.”
