Is Headline Office Vacancy a True Reflection of Market Health?
While headline office vacancy rates report overall available space, industry data suggests these figures may overstate genuine tenant choice. A significant portion of older stock is becoming less competitive due to sustainability deficits, creating a bifurcated market that complicates traditional assessments of supply.

The Divergence in Vacancy Metrics
Office market reports broadly track vacancy, but the definition of highly leasable space is increasingly shifting toward sustainability criteria. Reports from JLL indicate a deepening vacancy chasm between high-performance office space and older, un-upgraded inventory. This divergence suggests that nominal headline vacancy figures may mask the underlying reality of how much available space actually meets modern occupier requirements.
Sustainability as a Market Catalyst
The push for sustainable space is a primary driver behind the current vacancy gap. Sustainability upgrades are increasingly dictating tenant preferences, meaning older stock that lacks these features becomes less attractive. This shift effectively creates a bifurcated market where tenant interest concentrates on high-efficiency assets, leaving older, un-upgraded inventory struggling to compete for occupancy.
The Outlook for Older Assets
As the market grapples with these shifting preferences, the performance gap between premium and secondary stock is highly notable. With the definition of leasable space increasingly tied to sustainability criteria, older properties may face ongoing structural challenges rather than cyclical fluctuations. Consequently, evaluating broad market health may increasingly require stakeholders to look beyond nominal headline metrics to assess the underlying sustainability features of available assets.
Stakeholders evaluating the office market may need to look beyond headline vacancy figures, as older un-upgraded stock increasingly faces structural challenges driven by shifting sustainability standards.
