PHYSICS PROOF

PHPP Annual Space Heating Demand (Qh) Balance Verification

$$ Q_h = Q_T + Q_V - \eta (Q_S + Q_I) = 38.2 + 8.4 - 0.95(21.2 + 13.5) = 13.6 \ \text{kWh/m}^2\text{a} \le 15.0 $$

In the PHPP v10 energy balance: Transmission heat losses QT (38.2) + Ventilation loss QV (8.4) minus Solar gains QS (21.2) and Internal gains QI (13.5). The net annual heating demand is Qh = 13.6 kWh/m²a, fully satisfying the statutory 15 kWh/m²a Passivhaus threshold.

Failure Mode Analysis: Conventional Errors vs SerVilla Mitigation

Comparative building physics study showing failure points avoided by SerVilla design.

RISK MITIGATION
The Performance Gap: Discrepancy Between Energy Labels and Real Bills Passivhaus Standard PHI / EN ISO 52000
Conventional Failure Risk

Generic buildings with theoretical A-ratings consume 60-120% more energy in reality due to unverified site workmanship.

SerVilla Engineering Solution

SerVilla uses PHPP v10 climate-specific modeling paired with mandatory Blower Door tests and IR thermography to guarantee verified performance.

Uncalibrated Diagnostic Tools and Box-Ticking Site Inspections EN ISO 9972 / EN 13187
Conventional Failure Risk

Bogus blower door tests fail to catch deep envelope punctures, leaving homeowners with drafty rooms and inflated utility bills.

SerVilla Engineering Solution

Annually calibrated Minneapolis Blower Door systems and FLIR Pro thermal imagers are operated by independent certified test engineers.

Frequently Asked Questions

Essential answers regarding steel construction, energy targets and project delivery.

PHPP is the internationally accredited thermal balance design software developed by the Passive House Institute in Darmstadt. Unlike standard national building code estimates which often suffer from a 30-50% performance gap, PHPP correlates with real-world energy consumption with remarkable precision. It calculates building orientation, local solar radiation, shading and ventilation to guarantee the statutory 15 kWh/m²a heating limit before construction starts.

SerVilla produces comprehensive structural calculation dossiers strictly complying with Eurocode 3 (EN 1993-1-3) and Eurocode 8 (EN 1998-1), complete with foundation anchor reaction schedules, member force diagrams and 3D IFC models ready for statutory check engineers (Prüfstatiker).

We execute a mandatory two-stage testing protocol. The preliminary diagnostic test is conducted before drywall boarding, allowing technicians to pinpoint and rectify any microscopic seal defect immediately using smoke pens. With this protocol, our buildings consistently achieve n50 figures between 0.30 and 0.45 h⁻¹ on their first attempt.

Thermography performed under a minimum 10-15°C indoor-outdoor temperature delta visually maps building skin surface temperatures. It validates that cavity insulation is continuous, warm edge spacers are functional and zero convective drafts or thermal bypasses exist behind claddings.

Yes. All data packages—including certified PHPP calculation sheets, Blower Door protocol certificates, U-value calculations and CE Declarations of Performance—are specifically structured to fulfill the strict evidence criteria of funding bodies such as KfW (Germany), SEAI (Ireland) and cantonal Minergie programs (Switzerland).
