While Verdical did not serve as the primary event planner, for five years (2015–2019), Verdical has co-hosted the after-party of the largest annual green building conference in the world along with 10-12 other companies each year. The conference attracts approximately 15,000–20,000 attendees annually and the After Party convenes approximately 500–1,000 attendees.

Through the 2019 event, the co-hosts were able to donate $8,000 to the Malcolm Lewis Impact Award Fund. The annual After Party is a chance for attendees to mix and mingle with other professionals in their industry.
