A home can achieve an additional Regenerative Certification through completing all of the checklist items on the GBH + Regenerative Tab. These points, in multiple categories, identify opportunities for a home to offset environmental impact in a way that conserves and produces more energy than it consumes. Regenerative processes are also highlighted in green on the checklist, as listed below. Required points are available together on the GBH + Regenerative spreadsheet tab. For the complete list of items on our checklist, and to download the print checklist, see our Certification Levels page.
Homes of every certification level are eligible for this additional Regenerative Certification when all of these GBH + Regenerative checklist items are completed, and all other program requirements are met. If you have questions, please contact our Green Built Homes Project Manager by emailing homes@greenbuilt.org or calling 828.254.1995.
Site & Landscape
Healthy outdoors by using erosion control and saving existing trees.
Min 5 pts required
Site Disturbance
* Calculating Stormwater Runoff
a. Quantify the stormwater created based on 10 year storm (NOAA – Precipitation Rates) (2)
b. Install stormwater control systems to manage a 10 year storm (EPA WaterSense Smart Outdoor Practices) (1-10)
NOTE: Cannot be taken in conjunction with Site Opportunity #1
NOTE: Identify areas to be preserved and develop a strategy for avoiding mechanical and chemical damage, grade changes, trenching, filling, and compaction. An arborist (sometimes available through the local planning department) can help you decide which trees can be saved and can work with the builder to protect the trees throughout each construction phase. It is important to involve a knowledgeable professional during this planning phase to ensure actual survival of trees but not required. The end result should be a document (written or graphic) that can be physically posted on the job site. The Tree Preservation Plan shall be reviewed with subcontractors and posted on the job site at the beginning of the project.
