KMK 2.04.05-97 PDF

Full title and description

KMK 2.04.05-97 — "Отопление, вентиляция и кондиционирование" / "Heating, ventilation and conditioning" (national design norms for heating, ventilation and air‑conditioning systems in the Republic of Uzbekistan; includes later amendments).

Abstract

KMK 2.04.05-97 is a set of national technical rules and design norms that establishes requirements for the planning, design, installation and commissioning of heating, ventilation and air‑conditioning (HVAC) systems for buildings and structures in Uzbekistan. The document replaces the earlier СНиП 2.04.05-91 and has been issued with subsequent amendments to incorporate energy‑efficiency and safety updates.

General information

• Status: Active / in force (published with amendments and referenced in Uzbek regulatory lists).

• Publisher: Approved and issued by the State Committee / Department for Architecture and Construction of the Republic of Uzbekistan (Goskomarkhitektstroy / Госкомархитектстрой).
• ICS / categories: Heating, ventilation and air‑conditioning — ICS classification commonly aligned with building services / HVAC series (e.g., ICS 91.140.* for central heating / ventilation & air‑conditioning systems).
• Edition / version: KMK 2.04.05-97 (1997) with recorded amendments published subsequently (Change No.1 — 2004; Change No.2 — 2011; Change No.3 / corrections published later, incl. 2020 updates in published lists).
• Number of pages: Varies by edition/format — commonly listed as about 92 pages (electronic listings) and up to ~100+ pages in some printed/annotated copies (examples found at 92–103 pages).

Scope

KMK 2.04.05-97 covers normative requirements for design and technical solutions related to heating, ventilation and air‑conditioning of residential, public and industrial buildings in Uzbekistan. Scope items include climatic design conditions, system selection and layouts, ductwork and piping design rules, thermal insulation, hygienic and microclimate parameters, energy‑saving measures and requirements for installation, testing and commissioning of HVAC systems. The standard was prepared to replace the Soviet-era СНиП 2.04.05-91 and to align national practice with updated energy‑efficiency and safety objectives.

Key topics and requirements

• Climatic design data and temperature regimes for buildings (design indoor/outdoor temperatures and seasonal criteria).
• Ventilation rates, air exchange and hygienic microclimate parameters for different occupancy types.
• Selection and arrangement of heating systems (centralized and local), radiators, boilers and heat distribution networks.
• Ductwork and piping design rules, fittings, supports and thermal insulation requirements (including references to thermal insulation KMK/SHNK documents).
• Requirements for air‑conditioning systems, filtration, humidity control and equipment placement.
• Fire and smoke control measures in ventilation systems (smoke dampers, control valves, functional classification).
• Energy‑efficiency provisions and recommended energy‑saving design solutions (amendments and guideline supplements address improved efficiency).
• Testing, commissioning and handover procedures for HVAC systems.

Typical use and users

Primary users are building services designers, mechanical (MEP/HVAC) engineers, project architects, HVAC contractors, commissioning and testing teams, building inspectors and regulatory authorities in Uzbekistan. The document is used during schematic and detailed design, equipment selection, construction supervision and commissioning to ensure compliance with national HVAC norms and energy‑efficiency requirements.

Q: What does it cover?

A: It covers climatic design data, ventilation and heating system requirements, ductwork and piping rules, thermal insulation, air‑conditioning design, fire/smoke control in HVAC systems, commissioning and energy‑saving recommendations for buildings and facilities.

Q: Who typically uses it?

A: Architects, MEP/HVAC designers, contractors, commissioning engineers and building authorities in Uzbekistan use KMK 2.04.05-97 during design, construction and acceptance of HVAC works.

Q: Is it current or superseded?

A: The 1997 KMK text remains a referenced national document but has been issued with amendments (notably in 2004, 2011 and further updates referenced in 2020 lists). Users should confirm the latest amendments or any newer KMK/SHNK publications (some KMK items were updated in later years, e.g., 2018 editions of related KMK documents). Check national regulatory listings for the most recent status before design or regulatory submission.

Q: Is it part of a series?

A: Yes — KMK 2.04.05-97 belongs to the KMK family of Uzbek construction norms and is used together with other KMK and SHNK documents covering thermal engineering, insulation, energy norms and fire safety for building services. Companion guides and supplements provide energy‑saving design advice tied to KMK 2.04.05-97.

Q: What are the key keywords?
