ISO 18292:2011/Cor 1:2012

Overview

ISO 18292:2011/Cor 1:2012 is a technical corrigendum to the international standard ISO 18292:2011, which addresses the energy performance of fenestration systems in residential buildings. This corrigendum, published by the International Organization for Standardization (ISO) on April 1, 2012, provides a critical correction to the calculation procedure used to evaluate the thermal efficiency and overall energy impact of windows, doors, and other fenestration elements.

Fenestration systems significantly influence the energy consumption of residential buildings by affecting heat transfer, solar gain, and air infiltration. Accurate calculation methods are essential to ensure compliance with energy efficiency regulations and to promote sustainable building designs.

Key Topics

• Correction to Calculation Procedure
  The corrigendum specifically replaces Equation (20) on page 16 of the original standard, which is a formula used in evaluating pressure differences and heat transfer related to fenestration components.

• Thermal Performance Metrics
  The standard focuses on methods to quantify thermal losses or gains through fenestration systems, critical for assessing building envelope efficiency.

• Energy Use Optimization
  By applying the corrected calculation method, building designers and engineers can better predict energy consumption patterns and optimize fenestration design for enhanced energy savings.

• ISO/TC 163/SC 2 Involvement
  The Technical Committee ISO/TC 163, Subcommittee SC 2, specializing in thermal performance and energy use in buildings, is responsible for the corrigendum, reinforcing the document's authoritative basis.

Applications

• Building Design and Engineering
  Architects and engineers utilize the corrected calculation procedure in ISO 18292:2011/Cor 1:2012 to accurately model fenestration energy performance during the design phase of residential buildings.

• Energy Certification and Compliance
  Regulatory bodies and energy auditors reference the standard to ensure new or renovated buildings meet energy efficiency codes related to window and door specifications.

• Product Development and Testing
  Manufacturers of windows, doors, and glazing systems employ the standard to test and certify their products' energy performance, ensuring market competitiveness.

• Simulation Software Development
  Software tools for building energy simulation integrate these calculation methods to provide reliable predictions of fenestration-related energy losses and gains.
