Radical Retrofit: Adapting cities for a resilient future.

Key Points:

1. Retrofitting vs. New Construction: Retrofitting existing buildings is increasingly recognized as effective for meeting urban needs and enhancing resilience, especially in developed countries.
2. Retrofitting Momentum and Drivers:
   • Demand is growing due to urbanization, climate goals, market forces (tenant demand for sustainability, operational cost savings), regulatory pressures (energy efficiency standards, carbon reduction mandates), and investor ESG goals.
   • Light, moderate, and deep retrofits offer varying levels of energy savings (10-30% for light/moderate, 40-90% for deep).
   • Policies (standalone mandates, building codes, financial incentives like grants/subsidies) are the strongest catalysts.
   • Certifications (LEED, BREEAM, WELL) enhance property value.
3. Challenges Hindering Retrofits:
   • Financial: High upfront costs and long payback periods deter action. Lack of adequate financing options, poor risk-sharing mechanisms, and funding gaps exist.
   • Technical: Integrating modern systems with legacy infrastructure, skills shortages for skilled labor and retrofit-specific training, data fragmentation, and technical execution difficulties.
   • Regulatory & Behavioral: Unclear or insufficient government policies, lack of standardized pathways, split incentives between owners/tenants, weak policy leadership, and public misunderstanding of benefits.
   • Workforce: Shortage of specialized retrofit workers.
4. Pathways to Accelerate Retrofitting by 2030 (Economist Impact & JLL):
   • 1. Build Awareness: Comprehensive communication campaigns reframing retrofitting’s benefits.
   • 2. Translate Awareness into Action: Implement robust policies, regulations, and financial incentives (including performance-based financing).
   • 3. Quantify Full Benefits: Go beyond energy savings to include health, resilience, productivity, and economic returns.
   • 4. Unlock Innovative Financing: Scale blended finance, green bonds, C-PACE, ESCOs, and PPPs.
   • 5. Leverage Technologies: Use AI, digital twins, smart sensors for optimization, data management, and standardization.
   • 6. Address Talent Bottleneck: Invest in education, training programs, apprenticeships, and workforce development planning.
5. Conclusion: Retrofitting is urgent for climate mitigation, economic value, and urban resilience. Systemic change through better collaboration, finance, metrics, and workforce development is essential. Cities must tailor strategies to their context and integrate retrofitting into broader urban planning.
