Описание (английский):

ISO 13675:2013 is the general standard on generation by combustion sub-systems (boilers) for oil, gas, coal and biomass burning. It specifies the required inputs, calculation method, and resulting outputs for space heating generation by combustion sub-systems (boilers) including control. ISO 13675:2013 is also intended for the case of generation for both domestic hot water production and space heating.

Overview

ISO 13675:2013 - Heating systems in buildings - Method and design for calculation of the system energy performance - Combustion systems (boilers) - is the ISO system standard for energy calculation of combustion-based heat generation sub‑systems (boilers). It covers oil, gas, coal and biomass boilers and defines the required inputs, calculation method, and resulting outputs for space heating and combined space heating/domestic hot water production, including control strategies and auxiliary energy use.

Key topics and technical requirements

Scope and objective: Provides a systems‑level method to calculate energy performance of combustion sub‑systems rather than product specifications. Useful for compliance checks, design optimization and retrofit assessment.

Inputs and outputs: Specifies the data needed (e.g., generator performance characteristics, gross calorific value, operating modes) and the output energy indicators for system performance evaluation.

Boiler types: Addresses a range of boilers - condensing, non‑condensing, biomass boilers, low‑temperature, modulating, multistage and on/off units - and how their operating characteristics affect energy use.

Calculation method: Defines a calculation period/step approach (hourly, monthly or seasonal), heat balance of the generation sub‑system, and methods to account for boiler efficiency, combustion power, and part‑load behavior.

System losses and recovery: Requires accounting for heat losses to flue/chimney, generator and storage tank envelope losses, and distinction between recoverable and non‑recoverable system thermal losses.

Controls and auxiliary energy: Includes effects of control strategies (on/off, modulation, cascading) and auxiliary electrical energy for pumps, fans and electronics in the system energy balance.

Documentation and annexes: Includes informative annexes with formulas, default values, calculation examples (e.g., modulating condensing boilers) and guidance on gross calorific values.

Practical applications

Energy performance compliance assessment against regulatory targets.

Detailed design and comparison of alternative heating system configurations.

Energy audits and retrofit analysis to quantify savings from upgrades (e.g., switching to condensing or modulating boilers, adding heat recovery).

Performance modelling for mixed space heating and domestic hot water systems in residential, commercial and institutional buildings.
