Thermal & Acoustical Calculations

Performance Metrics That Drive Compliance and Comfort

Alu Group provides detailed thermal and acoustical calculations to support energy efficiency goals, regulatory approvals, and occupant comfort. These evaluations form a critical part of the façade design and submittal process, ensuring that each system meets both functional and environmental expectations.

Scope of Services

Thermal Transmittance (U-Value) Analysis

Calculation of system-level U-values based on glazing composition, profile insulation, and spacer configuration — aligned with regional climate zone requirements and energy codes.

Solar Heat Gain Coefficient (SHGC)

Determination of SHGC and light transmittance for façade elements, used for envelope modeling and daylighting analysis.

Acoustic Performance (STC / Rw Ratings)

Sound transmission analysis based on glass type, cavity design, and frame configuration — supporting specifications for urban, educational, and hospitality environments.

Report Preparation

Issuance of calculation sheets and performance documentation formatted for submission to building authorities, energy consultants, or sustainability auditors.

Standard & Methodology

01

Calculations follow ISO, EN, ASTM, and NFRC standards, depending on project region.

02

Input data is derived from certified component testing and manufacturer specifications.

03

Performance values are optimized through system selection, spacer choice, and glazing configuration.

Benefits

Facilitates compliance with international energy and acoustic codes.

Enables participation in certification programs such as Passive House, LEED, or BREEAM.

Assists in optimizing occupant comfort while reducing operational energy demand.

Verified Performance from Design to Delivery

By quantifying thermal and acoustic performance early in the project lifecycle, Alu Group ensures that façade systems contribute meaningfully to the energy and comfort goals of the building. These calculations also serve as a foundation for design refinement, certification efforts, and code compliance worldwide.
