EN 15603-1 Energy Performance Calculation
The EN 15603 series of standards provides a harmonized approach to the calculation of energy performance in buildings. This section focuses on the first part, EN 15603-1:2007 - Methodology for calculating the annual primary energy demand and the annual CO₂ emissions of buildings. This service is critical for quality managers, compliance officers, R&D engineers, and procurement teams looking to ensure their projects meet stringent sustainability and energy efficiency standards.
The methodology outlined in EN 15603-1 specifies a framework for calculating the primary energy demand (PED) of buildings. PED includes all forms of energy used directly or indirectly by a building over its lifecycle, including heating, cooling, lighting, hot water, and ventilation systems. This approach is essential for sustainable design and optimization.
The calculation process involves several key steps:
- Identification of the building's components
- Detailed modeling of energy consumption
- Data collection on energy inputs
- Application of conversion factors for different types of energy (electricity, natural gas, etc.)
- Calculation of primary energy demand and CO₂ emissions
The methodology is designed to be versatile, allowing for the calculation of energy performance across various building typologies. This ensures that the results are accurate and can be used effectively in different contexts.
EN 15603-1 aligns with broader sustainability goals by providing a standardized approach that supports compliance with national and international regulations. By using this methodology, organizations can ensure their projects meet stringent energy efficiency standards while also contributing to global climate change mitigation efforts.
Applied Standards
The EN 15603 series of standards is an essential part of the European Union's legislative framework for promoting sustainable buildings. This service strictly adheres to these standards, ensuring that calculations are accurate and align with regulatory requirements.
The key elements of the methodology include:
- EN 15603-1: Methodology for calculating the annual primary energy demand and the annual CO₂ emissions of buildings
- ISO 5208: Energy balance in buildings
- ASTM E2477: Standard practice for estimating the energy performance of commercial buildings using building energy modeling software
The methodology is supported by these standards, providing a robust framework that can be used across various sectors.
