Standard ($6,900, 25 days, 4 revisions):
Full web app with ROI, incentive stacking (up to 60%+ ITC), SREC pricing, EV integration (extra panels, fuel savings, CO₂) + professional PDF with charts/tables + customizable UI + API backend + deployment support + full source code.
Advanced ($12,900, Max 42 days, 6 revisions):
Complete BIPV suite: structural loads (wind/dead, pressure equalisation, ULS, fixing forces) + energy yield (kWh, LCOE, NPV, IRR, CO₂) + advanced PDF with breakdowns + custom dashboard + ML optimization + full API suite + documentation + 1-month support + complete source code.
All tiers deliver traceable, auditable outputs — no black-box. Tools ready for installers, facade engineers & developers to deploy immediately.

About Tinashe
Compliance-as-a-Service (CaaS) | ESG & Solar Pre-Feasibility Screening
Suzhou, China - 7:26 am local time
Operating under a Compliance-as-a-Service (CaaS) model, I deliver advanced pre-feasibility analysis, asset underwriting risk screening, and early-stage bankability reviews. I do not deal in "black boxes" or generic rules-of-thumb. Every calculation engine I deploy is highly customizable—allowing us to fine-tune physical boundaries, local utility structures, and precise fiscal logic to match your project parameters—while remaining entirely grounded in explicit, peer-reviewed statutory citations.
⚠️ EXPLICIT BOUNDARY DISCLAIMER: I provide high-fidelity screening software models and analytical reports for internal due diligence, investment committees, or lender disclosures. I do not provide official building energy certifications, formal engineering designs, legal tax opinions, or licensed on-site property assessor stamps.
🚀 PRE-FEASIBILITY COMPLIANCE ENGINES READY FOR CUSTOM CONFIGURATION:
1. EU PROPERTY ESG COMPLIANCE SCREENING ENGINE:
• Target Markets: Germany (GEG 2024), France (Décret Tertiaire), Spain (CEE), Italy (APE), Netherlands (NTA 8800), Poland, Sweden (BBR), and the United Kingdom (MEES).
• Core Metrology & Standards: EN ISO 52000-1:2017 primary energy balances, EN 16798-1:2019, and EPBD Directive 2024/1275 Article 7 framework targets.
• Deliverables: Translates raw multi-fuel delivery arrays into cross-border Energy Performance Certificate (EPC) pre-assessment estimations. Tracks localized Primary Energy Factors (PEFs) and grid emission factors to isolate exact calendar Stranding Risk Horizons (e.g., matching the hyper-strict Dutch *Kantoreneis* EPC C mandate or France's Loi Climat). Outputs automated "Brown Discount" valuation updates built on net retrofit CAPEX, maximum municipal penalty exposures calibrated at €100/m²/yr (BPIE mid-estimates), and JLL-aligned cap rate expansions (125–200bps).
2. C&I SOLAR & ENERGY STORAGE BANKABILITY SCREENING ENGINE:
• Target Markets: Core African markets including Nigeria, South Africa, Kenya, Ghana, Egypt, Tanzania, Ethiopia, Zambia, Senegal, and Morocco.
• Core Metrology & Standards: ISO 8528-1 generator metrics, IEC 61724-1 P50/P90 performance ratio equations, NREL ATB 2024 battery storage CAPEX curves, and IFC debt stress-testing protocols.
• Deliverables: Generates lender-grade pre-feasibility audits for complex off-grid or weak-grid sectors (Manufacturing, Cold Chain, Telecoms, Hospitality, Agro-processing). Evaluates definitive diesel-to-solar displacement splits, Levelized Cost of Energy (LCOE), Levelized Cost of Storage (LCOS), and runs automated multi-scenario Minimum DSCR debt coverage pass/fail validations to clear early-stage investment committees.
3. COMMERCIAL SOLAR INVESTMENT & INCENTIVE INTEL ENGINE:
• Target Markets: US Commercial Real Estate (CRE) energy transformations.
• Core Metrology & Standards: NREL PVWatts V8 physics, NASA POWER MERRA-2 (22-year climate averages), ASTM E1057 (NPV), ASTM E917 (IRR via Newton-Raphson iteration), and Jordan & Kurtz panel degradation models.
• Deliverables: Audits multi-variable financial sensitivity matrices (5 scenarios tracking yield and utility rate variances) alongside deep regulatory penalty elimination screening. This includes NYC Building Emissions Law (LL97 at $268/tCO₂e), Boston BERDO 2.0 ($234/tCO₂e), DC BEPS, Maryland BEPS, Energize Denver, and the Washington Clean Buildings Act. Models complete IRA 2022 §48E tax credit stacking—including the base 30% Investment Tax Credit (ITC) plus bonus adders for Energy Communities (Notice 2023-29), Domestic Content (Notice 2023-38), and MACRS 100% bonus depreciation under §168k.
🛠️ INTERACTION & DEPLOYMENT MODES:
• CaaS Report Processing: Provide your raw asset profiles (monthly utility data, physical dimensions, location parameters) and receive a customized, fully cited, investor-ready PDF pre-feasibility package within hours.
• Enterprise API Integration: Instantly expose these calculations to your internal screening software. I build secure Python/FastAPI pipelines to integrate and configure my engine cores directly behind your web applications, internal CRMs, or underwriting platform.
Stop risking capital allocations on fragile, unverified spreadsheet models. Let's talk to integrate an unshakeable, fully cited compliance screening pipeline into your workflow today.
