New regulations in low-rise construction in Russia

From January 1, 2025, new regulations in low-rise construction concerning the thermal protection of buildings have come into force, according to the updated code of practice SP 50.13330.2024. These changes aim to improve energy efficiency and enhance the operational conditions of residential and public buildings.

Key Changes in SP 50.13330.2024

Mandatory Thermal Imaging Inspection

One of the key innovations is the requirement for mandatory thermal imaging inspection upon project completion. This will allow for a more accurate assessment of thermal insulation conditions and the identification of potential heat loss issues at the acceptance stage of buildings.

Increased Insulation Thickness

According to the new requirements, insulation thickness must be increased by 15%. This change is necessary to enhance thermal insulation levels, which in turn will reduce heating costs and improve indoor comfort. Increasing insulation thickness will significantly reduce heat loss, especially during colder seasons.

Use of Vapor Barrier Membranes

The new standards require the use of vapor barrier membranes with a coefficient of Sd ≥ 5 m. This requirement is aimed at preventing condensation formation inside structures, which can lead to the deterioration of their thermal insulation properties and an increased risk of mold and mildew.

Installation of Facade Deflectors

The regulations also introduce the requirement for the installation of facade deflectors to ensure subsystem ventilation. This will help prevent moisture accumulation and ensure the durability of facade structures.

Economic Implications of the Changes

According to expert estimates, the implementation of the new standards may lead to an increase in construction costs by 7–12%. However, these expenses will be offset by a 25% reduction in operating costs over the next ten years. Improved building energy efficiency will significantly lower heating and ventilation expenses, which is particularly relevant given the continuous rise in energy prices.

The changes in SP 50.13330.2024 represent an important step towards improving energy efficiency and comfort in low-rise construction. The mandatory implementation of new technologies and materials will not only enhance construction quality but also ensure long-term savings for private homeowners. It is crucial for designers and builders to closely monitor these changes and adapt their approaches to design and construction in accordance with the new requirements.
