EN ISO 10077-1 Total Window U-Value (Uw) Calculation

$$ U_w = \frac{A_g U_g + A_f U_f + l_g \Psi_g}{A_g + A_f} = \frac{1.75(0.50) + 0.55(0.80) + 5.6(0.030)}{2.30} = 0.775 \ \text{W/m}^2\text{K} $$

For a standard 1.23 x 1.48 m test window (total 2.30 m²): Triple Low-E glass area 1.75 m² (Ug = 0.50), insulated frame 0.55 m² (Uf = 0.80) and Swisspacer Ultimate warm edge spacer (Ψg = 0.030). The resulting composite Uw = 0.78 W/m²K qualifies for Passivhaus certified component status (phA).

Failure Mode Analysis: Conventional Errors vs SerVilla Mitigation

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

RISK MITIGATION
Relying on Interior Curtains to Block Summer Solar Heat DIN 4108-2 / EN 13363-1
Conventional Failure Risk

Solar radiation entering through glass traps heat inboard (greenhouse effect); interior curtains fail to prevent room temperatures exceeding 35°C.

SerVilla Engineering Solution

Motorized external Z-slat Raffstore blinds deflect 85-90% of solar radiation outside the thermal envelope (effective gtot <= 0.10).

Using Conventional Aluminum Glazing Spacers Causing Edge Condensation EN ISO 10077-1
Conventional Failure Risk

Aluminum conducts cold directly into the glass rim; moisture trickles down windows, damaging sills and fostering mold spores.

SerVilla Engineering Solution

Swisspacer Ultimate composite warm-edge spacers (Psi_g = 0.030 W/mK) maintain internal glass edge temperature well above 17°C.

Solar Heat Gain & Summer Comfort Physics

01

Net Energy Gain in Winter

South-facing triple-glazed windows collect more free passive solar heat through solar gain (g >= 50%) than they lose.

02

External Shading is Non-Negotiable

Internal blinds trap heat indoors. Exterior automated louvres reflect radiation before glass contact, stopping overheating.

03

Elimination of Radiant Cold Chills

Inner glass temperature stays at 17.5°C when outdoor is -10°C, eliminating downdraft chills and perimeter radiators.

04

RAL Certified 3-Layer Sealing

Sealed with interior airtight tape, flexible acoustic foam core and breathable weather-tight exterior band.

5-Point On-Site Quality Assurance Checklist

1
Glazing Label Verification: Certified 4-16Ar-4-16Ar-4 Low-E unit with verified 90%+ argon cavity concentration.
2
Warm Edge Spacer Inspection: Swisspacer Ultimate thermal spacer confirmed around entire glass perimeter.
3
Pre-Wall Bracket Mounting: Windows anchored via thermal composite sub-frames rather than direct metal-to-metal screws.
4
Raffstore Wind Sensor Integration: Automated solar blinds tested for obstacle detection and automatic storm retraction.
5
Weep-Hole & Gasket Calibration: Compression gaskets and drainage paths checked for watertight performance.

5. Triple-Glazed Passive Fenestration & Automated Solar Shading

In passive house architecture, windows are not merely daylight openings—they function as net-positive passive solar collectors. SerVilla triple-glazed systems capture more solar radiation during winter days than they lose via thermal transmission across 24 hours.

Technical Glazing & Framing Specifications

  • Triple IGU Assembly (Ug = 0.50 W/m²K]: 48 mm dual Low-E, dual argon-filled cavity (4-16Ar-4-16Ar-4]. Inner pane temperature never drops below 17.5°C when outside ambient drops to -10°C, eliminating downdraft chills and perimeter radiators.
  • Warm Edge Spacer Technology: Swisspacer Ultimate composite thermal spacers replace metallic aluminum, virtually eliminating edge condensation and mold around the perimeter glass seal.
  • Thermally Decoupled Frames (Uf = 0.75 - 0.85 W/m²K]: Multi-chamber steel-reinforced uPVC or timber-aluminum composite profiles achieving overall Uw <= 0.80 W/m²K (Passivhaus phA class].

Exterior Automated Solar Shading (Raffstores & Zip-Screens]

Preventing summertime overheating requires blocking direct radiation on the exterior side of the glass. SerVilla specifies motorized exterior Venetian blinds (Raffstores] or heavy-duty architectural zip-screens on south and west facades. With a solar shading coefficient of Fc = 0.15, 85% of solar heat is intercepted externally without reliance on intensive active AC cooling.

SerVilla Engineering Note: Details documented in this specification are engineered project-specifically based on local soil conditions, statutory climate data, wind/snow loads and chosen energy targets (PHI, KfW 40, Minergie). Certified execution drawings govern contracts.

Frequently Asked Questions

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

While double-glazing achieves Ug values around 1.1-1.4 W/m²K, modern triple-glazed argon units achieve Ug = 0.5-0.6 W/m²K (over 2.5 times more insulative). With double-glazing in winter, the inner glass surface cools down to 10-12°C, inducing radiant draft. Triple-glazing keeps inner glass warm (17-18°C), completely eliminating cold air drop.

Super-insulated homes can overheat if solar gains are unmanaged. SerVilla integrates external motorized Venetian blinds (Raffstores) or exterior zip-screens on south and west elevations. Shading the exterior glass reflects up to 85% of solar radiation before it enters the home, maintaining cool interiors without heavy AC usage.

Standard IGUs utilize metallic aluminum spacers that act as thermal conductors along the perimeter of the glass pane, generating condensation and mold. Our Swisspacer composite spacers provide thermal resistance at the edge of the glass, elevating perimeter temperatures and eliminating condensation.

Both deliver certified Passive House performance (Uw <= 0.80 W/m²K). Premium multi-chamber uPVC frames offer outstanding cost-to-performance ratios and zero maintenance. Timber-aluminum composite frames provide the tactile warmth of natural wood inside and powder-coated architectural durability outside.

Standard sliding doors leak air because they rely on brush seals. In contrast, our Lift-and-Slide (Hebeschiebe) systems drop the moving sash into compressed multi-point EPDM gaskets when locked, achieving verified Class 4 airtightness matching fixed glazing performance.
