Greenbacker hires new Head of Real Estate Investments

Former Blackstone Managing Director Zackowitz to oversee firm’s sustainable real estate investments

New York, NY, August 17, 2023 — Greenbacker Capital Management (“GCM”), a leading renewable energy asset manager, is pleased to announce that David Zackowitz has been hired as the firm’s new Head of Real Estate Investments. Zackowitz will lead GCM’s fourth sustainability driven investment strategy, focused on acquiring commercial and residential property where the company can reduce greenhouse gas (“GHG”) emissions and energy use intensity, as well as add additional sources of renewable power.

As Head of Real Estate Investments, Zackowitz will manage GCM’s investments in real estate—a sector that contributes approximately 40% of global GHG emissions.1 He will oversee deal origination and deploy capital to improve energy efficiency and support the expansion of electric vehicle fleet charging and rooftop community solar across the real estate assets acquired. Zackowitz brings 22 years of experience in principal investments, asset management, and portfolio company oversight across the real estate asset class, including acquiring and implementing value-add strategies for $25 billion of commercial properties throughout his career. Prior to GCM, he was a Managing Director at Blackstone, the world’s largest alternative assets manager.

Zackowitz joins the company’s leadership team during a period of expansion for both GCM and its affiliates (collectively, “Greenbacker”). During the last year, Greenbacker’s AUM2 increased from $2.8 billion on September 30, 2022 to approximately $3.3 billion as of June 30, 2023. Over the same period, the clean power generation and storage capacity of Greenbacker’s project fleet increased from 3.0 gigawatts (GW) to 3.8 GW across 500 projects in 33 states, Canada, Puerto Rico, and Washington, DC.3

“David perfectly complements Greenbacker’s existing investment expertise and expands our ability to invest across the clean energy and sustainability focused asset class,” said Charles Wheeler, CEO of Greenbacker. “His experience and track record with some of the country’s leading real estate investment platforms will bolster Greenbacker’s capabilities within sustainable real estate—a sector with significant opportunity for investment to drive a clean energy future.”

“I am thrilled to join the talented team at Greenbacker and look forward to growing the firm’s sustainable real estate business.  Following one of the hottest summers on record, climate legislation will continue to expand in an effort to reduce emissions in the space,” Zackowitz said. “Greenbacker is strategically positioned to leverage its 360-degree view of the sustainability investment landscape and facilitate the decarbonization of the built environment.”

In the US, more than 600 local governments nationwide have introduced Building Performance Standards requiring buildings to meet certain decarbonization or clean energy targets.4 In addition to the many state and local incentives encouraging sustainable real estate,5 the Inflation Reduction Act has provided $369 billion6 of federal support to reduce greenhouse gas emissions and increase domestic investment in the clean energy sector.
