Section 1 of 5Why Building Retrofits Matter
Over 75% of buildings standing today will still be in use in 2050. Since buildings account for 40% of global energy consumption and emissions, retrofitting existing structures is essential for meeting climate goals. New construction alone cannot solve the climate crisis—we must transform the buildings we already have.
Building retrofits range from simple upgrades like LED lighting to comprehensive deep retrofits that transform energy performance. The key is identifying the right interventions based on building age, condition, usage patterns, and available financing.
Retrofit Impact Potential
Well-executed retrofits can reduce building energy use by 30-50%, cut carbon emissions by 40-60%, and improve occupant comfort and health—all while increasing property values by 10-20%.
