HOW THIS VERIFICATION WORKS

  1. Step 1: Compute annual POA irradiance for arbitrary tilt/azimuth using Perez transposition model with IAM correction — engineering workflow step. Follow the documented method for manual execution.
  2. Step 2: Compute effective monthly demand peak subject to ratchet clause and TOU window filtering — engineering workflow step. Follow the documented method for manual execution.
  3. Step 3: Calculate design wind pressure on BIPV cladding per ASCE 7-22 Section 30.11 — performs a deterministic calculation from the provided inputs. No acceptance criterion is applied; the result is CALCULATED only.
  4. Step 4: Derive maximum fastener spacing from wind pressure and anchor capacity — engineering workflow step. Follow the documented method for manual execution.

This tool coordinates 0 validation steps and 4 calculation steps. The overall engineering decision uses ALL_REQUIRED_VALIDATION_PASS aggregation: only validation steps contribute to the pass/fail outcome; calculation steps produce data only.

METHODS & EQUATIONS

All formulas are resolved from canonical runtime definitions and executed deterministically by the client-side engine.

Step 1: Compute annual POA irradiance for arbitrary tilt/azimuth using Perez transposition model with IAM correction

Manual Workflow
For each hour i: (1) Compute solar zenith angle θ_z and solar azimuth γ_s from φ, date/time, and ephemeris; (2) Apply horizon profile h(α) to clip direct beam when θ_z > h(γ_s − γ); (3) Compute POA irradiance using Perez transposition: G_poa = G_b * cosθ_i + G_d * [F1(θ_z,β) * (1+cosβ)/2 + F2(θ_z,β) * (1−cosβ)/2] + ρ * (G_b * cosθ_z + G_d) * (1−cosβ)/2, where F1, F2 are Perez anisotropy coefficients; (4) Apply IAM factor: iam = a0 + a1 * cosθ_i + a2 * pow(cosθ_i,2); (5) Sum G_poa * iam over 8760 hours and divide by 1000 for kWh/m²/yr.

Step 2: Compute effective monthly demand peak subject to ratchet clause and TOU window filtering

Manual Workflow
For each month m: (1) Extract 720-hour (30-day) subsequence of L(t); (2) Identify on-peak hours using binary schedule S_on(t); (3) Compute raw peak: P_raw,m = max{L(t) | t ∈ on-peak hours in month m}; (4) Apply ratchet: P_eff,m = max(η_ratchet × P_hist_max, P_raw,m); (5) Demand charge for month m = P_eff,m × R_demand; (6) Annual sum = Σₘ P_eff,m × R_demand.

Step 3: Calculate design wind pressure on BIPV cladding per ASCE 7-22 Section 30.11

Formulaq_h*(GC_p-GC_pi)

Step 4: Derive maximum fastener spacing from wind pressure and anchor capacity

Manual Workflow
Tributary area per anchor A_t = s_x * s_y. Required anchor capacity: F_req = p * A_t * 2.0 (ASCE 7-22 safety factor). Rearranged: s_x * s_y ≤ F_u / (2.0 * p). Assuming square spacing s_x = s_y → s_max = sqrt(F_u / (2.0 * p)). Clamp to module dimension: s_max = min(s_max, w*1000, h*1000). Output in mm.

UNDERSTANDING THE RESULTS

PASS
A proven validation criterion passed. The engineering input satisfies the deterministic threshold.
FAIL
A proven validation criterion failed. The engineering input does not satisfy the deterministic threshold.
CALCULATED
A deterministic calculation completed, but no acceptance criterion exists for this step. CALCULATED does NOT mean PASS.
RESULT NOT VALID
Runtime executed but engineering validity requirements were not met.
INCOMPLETE
Required inputs or workflow steps are incomplete.

The overall decision reflects only validation steps. Calculation steps produce numerical results without pass/fail claims.

WHEN TO USE THIS TOOL
