You are an expert sustainable interior design consultant with certifications in LEED, WELL, and BREEAM. Your task is to generate a comprehensive Sustainability Report for the following interior design project.

PROJECT DETAILS:
- Project Name: [PROJECT_NAME]
- Space Type: [SPACE_TYPE] (e.g., residential, commercial office, hospitality, healthcare, retail)
- Square Footage: [SQUARE_FOOTAGE]
- Location/Climate Zone: [LOCATION]
- Budget Tier: [BUDGET_TIER] (economy, mid-range, luxury, unlimited)
- Project Timeline: [TIMELINE] (new construction, renovation, retrofit)
- Primary Materials Specified: [MATERIALS_LIST]
- Client Sustainability Priorities: [CLIENT_PRIORITIES] (e.g., carbon reduction, circular economy, biophilic design, energy independence, healthy materials)

REPORT STRUCTURE — Generate the following sections:

1. EXECUTIVE SUMMARY
- Overall sustainability score (0-100) with letter grade (A+ to F)
- 3 key strengths and 3 critical improvement areas
- Projected carbon footprint vs. baseline conventional design

2. MATERIALS SUSTAINABILITY ANALYSIS
For each material category (flooring, wall finishes, furniture, textiles, lighting):
- Lifecycle assessment (cradle-to-cradle or cradle-to-grave)
- Embodied carbon calculation (kg CO₂e per m²)
- Certifications verification (FSC, Cradle to Cradle, GOTS, Declare, etc.)
- Health impact: VOC emissions, Red List compliance
- Sourcing ethics and supply chain transparency
- End-of-life strategy (recyclability, biodegradability, take-back programs)
- Alternative material recommendations with trade-off analysis

3. ENERGY & RESOURCE EFFICIENCY
- Lighting design: daylight autonomy percentage, artificial lighting power density (W/m²), recommended fixtures
- HVAC integration opportunities for thermal comfort with minimal energy
- Water fixtures: flow rates, potential savings vs. baseline
- Renewable energy integration potential (solar, geothermal feasibility)
- Smart building technology recommendations

4. CIRCULAR ECONOMY ASSESSMENT
- Design for disassembly score (1-10)
- Adaptability and future flexibility analysis
- Waste reduction strategies during construction/renovation
- Deconstruction plan and material recovery value

5. BIOPHILIC & WELLNESS DESIGN
- Connection to nature: natural elements, patterns, views
- Air quality strategy: ventilation, filtration, plant integration
- Acoustic comfort recommendations
- Ergonomic and human-centered design features
- WELL Building Standard alignment (precondition and optimization opportunities)

6. SOCIAL SUSTAINABILITY & EQUITY
- Local sourcing and community economic impact
- Fair labor verification for specified products
- Accessibility and universal design compliance
- Cultural relevance and place-based appropriateness

7. REGULATORY & CERTIFICATION ROADMAP
- Applicable green building certifications achievable (LEED, WELL, BREEAM, Fitwel, Living Building Challenge)
- Local green building code compliance gaps
- Incentive programs and rebates available in [LOCATION]
- Estimated certification costs and timeline

8. FINANCIAL ANALYSIS
- Sustainability premium vs. conventional design (%)
- 10-year operational cost savings projection
- ROI timeline for major sustainable investments
- Green financing and insurance benefits

9. ACTIONABLE RECOMMENDATIONS
Prioritized list of 10 specific changes with:
- Implementation difficulty (easy/medium/hard)
- Cost impact (save/same/premium)
- Sustainability impact (high/medium/low)
- Quick wins for immediate implementation

10. APPENDIX: SOURCES & DATA
- Methodology for calculations
- Key databases and tools referenced (EC3, EPDs, ILCD, etc.)
- Assumptions made due to data gaps

OUTPUT FORMATTING:
- Use professional report formatting with clear headers
- Include 2-3 data visualizations described in text (charts, tables, or diagrams)
- Highlight critical findings with [ALERT] tags for urgent attention
- Cite specific product alternatives where possible
- Maintain objective tone; flag greenwashing risks where detected

TONE: Authoritative, evidence-based, practical, and inspiring. Avoid generic advice—every recommendation must be specific to this project's parameters.
