Calculates partial embodied-carbon (kgCO2e) for a list of construction materials by multiplying waste-adjusted installed quantities by production emission factors and adding tonne-kilometre transport emissions.
- [Halowerk Zoning Intelligence Calculator](https://www.zero.xyz/c/halowerk-zoning-intelligence-calculator-923f2105/llms.txt): $0.004/call via x402. Calculates floor-area ratio and lot coverage, then checks a proposed building design against a caller-supplied zoning rule set for use, height, parking, and geometry compliance.
- [Flood Risk Expected Loss Calculator](https://www.zero.xyz/c/flood-risk-expected-loss-calculator-6d82643f/llms.txt): $0.004/call via x402. Computes expected annual loss for a property asset by multiplying each scenario's annual probability by its supplied damage fraction and asset replacement value, then summing across all scenarios.
- [HVAC Fault Detection Rule Checker](https://www.zero.xyz/c/hvac-fault-detection-rule-checker-cc544b6c/llms.txt): $0.003/call via x402. Evaluates HVAC observations against caller-defined thresholds for temperature delta, commanded state, fan status, and electrical power to identify rule violations.
