The Arlington County Board updated Arlington’s Green Building Incentive Policy on Dec.12, 2020. This voluntary policy offers site plan developers bonus density in exchange for LEED Gold certification, additional energy requirements, and other environmental components. The voluntary policy was updated to keep up with changes to the building code, LEED rating system, technology, and market trends.
Any project accepted by the County Manager after June 30, 2023 shall meet the following revised criteria:
Energy Optimization

- Baseline Prerequisites
The following requirements depend on the FAR being pursued:
| 0.25 FAR |

0.55 FAR |
0.70 FAR |

Process
Clarification: Residential projects that earn bonus density in exchange for ENERGY STAR certification with a score of 75 do so using ENERGY STAR Portfolio Manager. The ENERGY STAR score is based on post-occupancy energy utility data. This is not certification through the ENERGY STAR Multifamily High Rise Program (New Construction).
Update for Multifamily Developments Requesting Green Building Bonus Density
Multifamily developments may now use either the LEED for Homes Multifamily or Earthcraft Virginia green building rating systems. See the full interpretation here.
