  • Nuveen CPACE Lending Fund IV closed its fourth round with more than $1B. It is the vehicle’s largest close since the 2023 launch.
  • Backers include Nuveen’s parent, TIAA, and insurance companies, with roughly 60% of the firm’s C-PACE loans funding new construction.
  • C-PACE has moved from niche to mainstream, hitting a record $3.7B in 2025. Banks are pulling back from construction lending.
Key Takeaways

According to Bisnow, Nuveen Green Capital has closed its biggest fund to date. The firm’s fourth C-PACE vehicle secured more than $1B in commitments, it said Tuesday. The raise deepens a fast-growing corner of commercial real estate finance.

How C-PACE Works

C-PACE stands for commercial property assessed clean energy. States authorize the loans, which fund environmentally friendly projects. The financing is fixed-rate and long-term. Borrowers use it for energy-efficiency upgrades, refinancing, climate resilience, and ground-up construction. At Nuveen, about 60% of C-PACE loans go to new construction and 40% to recapitalization deals.

Filling a Bank Lending Gap

One aim of the fund is to fill space left by traditional banks. Lenders like Bank OZK have trimmed commercial real estate exposure. Bank OZK, long a major construction lender, reversed course in recent quarters to reduce CRE exposure. C-PACE has stepped into that gap.

The sector’s expansion was already visible as C-PACE financing supported a $785M sustainable real estate fund. A record $3.7B in C-PACE financing was deployed in 2025, up 53% year over year. That single year represented about a quarter of all C-PACE originations since the program began in 2009.

The Details

Nuveen’s numbers show the climb. The fund launched in 2023, raises yearly, and has now gathered more than $3B. NGC pulled in $1.4B during its prior round and only $75M back in 2017. Loan originations reached $2.1B most recently, nearly double the $1.2B booked the year before. CEO Ali Cooley told Bisnow in February that stronger institutional demand is the driver.

It lets the firm offer attractive terms to institutional borrowers. One recent deal is a 691-foot mixed-use tower in Boston. Owner Millennium Partners drew a $281M loan through Massachusetts’ C-PACE program, the largest of its kind in New England.
