SP 50.13330.2012 PDF

Full title and description

SP 50.13330.2012 — "Тепловая защита зданий" (Thermal protection / Thermal performance of buildings). This document is the 2012 actualized edition of СНиП 23-02-2003 and was issued as a set of rules for design and assessment of the thermal protection (heat-engineering and energy-efficiency) of buildings; it has been published with Amendments No. 1 and No. 2.

Abstract

SP 50.13330.2012 establishes methodological requirements and normative limits for the thermal performance of building envelopes, methods to calculate reduced thermal resistance and heat losses, criteria for internal surface temperatures and condensation risk, classification of climatic and humidity conditions for design, and reference values / tables of heat-technical properties of common building materials. The document was intended as the basis for energy-related design decisions in residential, public, industrial and other buildings and was issued with two subsequent amendments that refined calculation procedures and appendix statuses.

General information

• Status: Withdrawn / replaced — superseded by SP 50.13330.2024 (new set of rules published 2024; SP 50.13330.2012 ceased to be applied from the date the 2024 edition entered into force).
• Publication date: Approved in 2012 (order approving the 2012 edition issued 30 June 2012) and put into regulatory effect during 2013 (introductory dates published with official acts).
• Publisher: Official publication issued by the federal authority responsible for building codes in Russia (originally published as an official edition by the Ministry/Department responsible for regional development / construction regulation and later maintained by the Ministry of Construction).
• ICS / categories: OКС 91.120.10 (building heat engineering / thermal protection of buildings).
• Edition / version: SP 50.13330.2012 — actualized edition of СНиП 23-02-2003; published with Amendment No. 1 (approved December 14, 2018) and Amendment No. 2 (approved December 15, 2021; introduced 16 January 2022).
• Number of pages: Common commercial / official printings of the 2012 edition are approximately 96–101 pages depending on print/appendix inclusion; official bibliographic records commonly list ~101 pages for the 2012 edition (with earlier and later printings varying slightly).

Scope

SP 50.13330.2012 applied to the design of thermal protection for residential, public, industrial, agricultural and warehouse buildings (generally buildings with an area above a modest threshold) where a regulated temperature and humidity regime must be maintained. The rules set requirements for the normalized (reduced) thermal resistance of building envelopes, methods to calculate heat loss through constructions (including constructions in contact with ground), internal surface temperature checks to prevent condensation, classification of climatic and humidity regimes for design, and recommended reference material properties and calculation procedures. The 2012 text and its amendments cover both prescriptive tables and calculation methods.

Key topics and requirements

• Definition of normative (reduced) thermal resistance and methods to calculate it for walls, roofs, floors, windows and other envelope elements.
• Procedures to calculate heat losses for whole buildings and for individual fragments of the envelope, including rules for constructions in contact with the ground.
• Requirements for internal surface temperatures and rules to check condensation risk (dew‑point checks) for different construction types and climates.
• Classification of climatic zones and humidity regimes for design (as basis for choosing resistance/rates and for heat‑loss calculations).
• Reference tables of thermal properties for common building materials; guidance on operating λ-values (service values) and on conditions A/B for thermal conductivity.
• Specific methodological amendments introduced in Amendment No. 2 (reclassification or status changes of several appendices, clarifications to calculation rules, revised requirements for temperatures of internal surfaces and floor‑to‑ground heat loss methodology).

Typical use and users

Primary users are building designers, thermal engineers, HVAC and envelope specialists, energy auditors, construction regulators and experts performing building permitting and technical expertise in Russia. The standard was used during design and review stages to justify envelope thermal performance, to assess condensation risk, and to calculate normative energy consumption for heating and ventilation in project documentation. It was also used as a normative reference in academic and applied research on building heat protection.

Q: What does it cover?

A: It covers normative values and calculation methods for thermal resistance of envelope elements, building heat-loss calculations, climatic and humidity classification for design, internal surface temperature/condensation checks, and reference tables of thermal properties and practical methodological rules.

Q: Who typically uses it?

A: Architects, building envelope and thermal engineers, HVAC designers, energy auditors, construction experts, and regulatory bodies involved in project review and technical expertise in Russia.

Q: Is it current or superseded?

A: Superseded — SP 50.13330.2012 (including its Amendments No.1 and No.2) has been replaced by SP 50.13330.2024, which was approved in 2024 and entered into force in mid‑2024; after that date the 2012 edition is no longer the operative set of rules.
