Operational green building certifications can boost GRESB performance scores
GRESB uses validated sustainability data from its annual real estate assessment, and Operational certifications can raise the certified floor-area share used for points in BC1.2.
GRESB is a global ESG assessment and benchmarking system for real assets, and its Real Estate Assessment is the annual submission that real estate companies and funds use to report building sustainability and operational performance. The submitted data is validated, scored, and benchmarked, and those results are increasingly used by investors to compare managers and guide capital allocation, according to Nareit.
Nareit says that improving scores often comes down to where a team can still move the needle, noting that many participants initially focus on management policies but later hit diminishing returns once that portion is mature. In that context, the outlet highlights building operations and performance data as the “real opportunity,” because steady operational improvements can translate into score movement when metrics are benchmarked against peers.
Operational green building certifications are described as one of the most direct ways to lift GRESB Performance scores, because they can increase the certified floor-area share in a portfolio, which GRESB uses to award points in BC1.2. Nareit also emphasizes that year-over-year data coverage is central to point gains and that tenant spaces, which account for most building energy use but are often a blind spot, are among the hardest data to capture.
