What is an EUI calculator and how does Intelli-Build AI calculate it?

EUI (Energy Use Intensity) is measured in kWh/m²/yr and represents total building energy consumption divided by floor area. Intelli-Build AI calculates EUI using building type, location climate data, fabric U-values, HVAC system efficiency, occupancy patterns, and lighting/equipment power densities — all validated against CIBSE, ASHRAE, and RIBA 2030 targets. Results are available in under 5 minutes for free.

What is CRREM and how does it affect my building?

CRREM (Carbon Risk Real Estate Monitor) provides science-based decarbonization pathways for buildings aligned with the Paris Agreement. Intelli-Build AI uses official CRREM 2.0 pathways to predict your building's stranding year — the point at which its carbon intensity exceeds the allowable pathway — helping property owners, investors, and ESG teams quantify climate-related financial risk.

Does Intelli-Build AI do CIBSE and ASHRAE compliant heating and cooling load calculations?

Yes. Intelli-Build AI performs full engineering-grade heating, cooling, and ventilation load calculations following CIBSE Guide A, ASHRAE Handbook of Fundamentals, BCO, Estidama, and regional standards. Calculations include fabric heat loss, infiltration, solar gains, internal gains, and ventilation loads with climate data for 195 countries.

Can I assess LEED, BREEAM, or WELL certification potential?

Yes. Intelli-Build AI includes a Green Certifications module that assesses your building's potential for LEED, BREEAM, WELL, Estidama (Pearl), Green Mark, NABERS, Fitwel, and more. The platform maps your project parameters to certification prerequisites and credits, identifying gaps and improvement opportunities.

How does the AI HVAC equipment specification work?

Intelli-Build AI uses calculated heating and cooling loads to automatically specify appropriate HVAC equipment — heat pumps, chillers, AHUs, VRF systems, fan coils, and more — from a database of real manufacturer products. It provides sizing, COP/SEER ratings, embodied carbon (TM65), BIM objects, and estimated costs from preferred suppliers.

What countries and building standards does Intelli-Build AI support?

Intelli-Build AI supports 195 countries with a database of 1,100+ building standards. Regional support includes UK (Part L, EPC, DEC, CIBSE), GCC (Estidama, GSAS, ASHRAE 90.1), EU (EPBD, EN standards), US/Canada (ASHRAE, IECC, NECB), Australia/NZ (NCC, NABERS), and Asia (BCA Green Mark, OTTV, J-Green). Standards are automatically updated daily.

Can Intelli-Build AI find grants and funding for building retrofits?

Yes. The Grant & Funding Research module uses AI to automatically discover available grants, loans, tax incentives, and government schemes for your specific location, building type, and retrofit measures. The platform has identified over £276 million in funding opportunities across its user base and can generate funding application documents.

Is Intelli-Build AI free to use?

Intelli-Build AI offers a free EUI assessment and CRREM stranding risk analysis — no credit card required, results in 5 minutes. Advanced modules including detailed load calculations, AI equipment specification, scenario planning, cost management, and funding research are available as paid add-ons with per-project or subscription pricing.
