SN RK 2.04-04-2013 PDF

Full title and description

SN RK 2.04-04-2013 — "Строительная теплотехника" (Construction / Building Heat Engineering). National construction norm of the Republic of Kazakhstan that establishes principles, calculation methods and normative requirements for heat engineering of buildings (thermal calculations, heat loss assessment, and requirements for enclosing structures and insulation materials).

Abstract

Sets requirements and methods for thermal engineering in building design: calculation of heat losses, selection of design indoor and outdoor temperatures, criteria for thermal protection of building envelopes, basic provisions for heating and ventilation load calculations, and recommended thermal characteristics (resistances/U‑values) of enclosing structures and insulating materials used in the Republic of Kazakhstan. The document was later superseded by an updated set of thermal-protection norms.

Scope

Applies to design and engineering of heat-related aspects of buildings in Kazakhstan: provides methods for calculating heat losses and heating loads, requirements for thermal protection of enclosing structures, recommended thermal performance (resistances/U-values) of walls, roofs and floors, and sets parameters for design indoor microclimate and outdoor design temperatures used in calculations. The standard was intended for use in project documentation for residential, public and industrial buildings where national thermal engineering rules apply.

Key topics and requirements

• Methods for calculating heat losses through building envelopes and through ventilation/infiltration.
• Design outdoor and indoor temperature parameters and their use in load calculations.
• Thermal protection criteria for enclosing structures (required thermal resistance/U‑value limits for walls, roofs, floors, windows).
• Guidance on insulation materials, detailing thermal bridges and durability considerations.
• Principles for sizing heating systems and basic links to ventilation and indoor microclimate requirements.
• Requirements and recommendations aimed at improving energy efficiency of buildings (as precursor to later thermal-protection norms).

Typical use and users

Used by architects, building designers, MEP (mechanical/electrical/plumbing) and HVAC engineers, energy auditors, construction project managers, building code and compliance officials, and academic or consulting professionals working on thermal calculations, insulation selection and energy-efficiency measures for buildings in Kazakhstan. Practitioners used the document when preparing design and project documentation prior to the introduction of the 2022 replacement.

Related standards

Closely related norms and documents in the СН РК family include other 2.04-series documents (lighting, noise protection, thermal protection of buildings), СП/СН РК standards on heating, ventilation and insulation (for example СН РК 2.04-01, СН РК 2.04-02, СН РК 2.04-03 and СН РК 2.04-05), and the later consolidated СН РК 2.04-07-2022 which now governs thermal protection requirements. These related documents were part of the national reform of construction norms adopted in the 2010s–2020s.
