The economic impact of ESG-Driven office building Renovations: Evidence from prime Spanish commercial real estate

Commercial real estate (CRE) faces a high prevalence of obsolete buildings that fail to align with modern workplace trends or European decarbonization targets. Although renovation is crucial to adapt these properties to market demands, the economic effects of such interventions have not been extensively explored. Existing literature often focuses on Anglo-Saxon markets or newly constructed buildings, addressing environmental aspects without a comprehensive Environmental, Social, and Governance (ESG)-based framework. This study aims to bridge this knowledge gap by analysing the economic impact of renovating three prime-location office buildings in Spain within an ESG framework. A mixed-methods approach is employed. First, ESG vectors are examined using audited pre- and post-intervention case study data, including required investment, operational expenses, property value, opportunity costs, profitability, tenant profiles, and decision-making processes. In a second stage, these findings are complemented with tenant surveys and asset manager interviews. The results demonstrate that comprehensive ESG-driven renovations significantly improve economic and sustainability outcomes compared to other comparable investment opportunities. The substantial increase in cash flow and attraction of high-profile tenants boosted gross income by up to 82% and property value by up to 84%. Renovating CRE into Class A buildings is a decision that yields both financial and non-financial benefits. As such, public policies could evaluate introducing incentives in lower-market-value areas to encourage renovations beyond prime locations.
