What is EN ISO 13790:2012

EN ISO 13790:2012 is a technical standard that provides guidelines for the calculation of energy use for space heating and cooling in buildings. It was developed by the International Organization for Standardization (ISO) with the goal of harmonizing the methods used for energy performance assessment of buildings. This standard is applicable to both new and existing buildings and can be used for various types of buildings, including residential, commercial, and public buildings.

Scope of EN ISO 13790:2012

The scope of EN ISO 13790:2012 encompasses the calculation of energy use for space heating and cooling in buildings, taking into account factors such as climate, building envelope, heating and cooling supply systems, and occupancy patterns. The standard provides a detailed methodology for calculating the energy demand and consumption, based on various parameters and inputs. It also includes guidance on the determination of reference climates, calculation periods, and energy balance equations.

Methodology of EN ISO 13790:2012

The methodology outlined in EN ISO 13790:2012 involves several steps. Firstly, the climatic data relevant to the location of the building is collected and processed. This includes temperature, solar radiation, and other weather parameters. Secondly, the building envelope characteristics, such as insulation, thermal mass, and air tightness, are taken into account. The third step involves assessing the heating and cooling systems, their efficiency, and control strategies. Finally, the occupancy and use patterns of the building are considered.

Benefits of EN ISO 13790:2012

EN ISO 13790:2012 offers several benefits to building professionals, designers, and policymakers. Firstly, it provides a standardized approach for evaluating the energy performance of buildings, allowing for meaningful comparisons and benchmarking. This enables stakeholders to identify areas for improvement and implement energy-efficient measures effectively. Secondly, it contributes to the development of more sustainable buildings by promoting energy-conscious design and construction practices. Lastly, compliance with this standard can result in reduced energy costs, improved indoor comfort, and reduced environmental impacts.
