The Business Case for Smart Building Retrofits
ROI analysis and implementation strategies for upgrading legacy buildings with modern IoT infrastructure and automation systems.
Introduction
With over 80% of buildings that will exist in 2050 already standing today, retrofitting existing buildings with smart technology is essential for meeting sustainability and operational goals. This guide examines the business case for smart building retrofits.
Why Retrofit?
Regulatory Pressure
Building performance standards are tightening globally. Cities are implementing building performance mandates that require efficiency improvements.
Tenant Expectations
Modern tenants expect technology-enabled workplaces with comfort, connectivity, and sustainability credentials.
Operational Costs
Energy costs continue to rise, while smart technology costs have decreased significantly, improving retrofit economics.
Asset Value
Smart buildings command premium rents and higher valuations in competitive markets.
