KFW40+ and EH40 Standards

The Significance and Need for Constructing New Homes in Compliance with the KFW40+ Standard

Modern requirements for building energy efficiency are becoming increasingly stringent, and one of the most important standards in this area is the KFW40+ standard. This standard, developed by the German Development Bank (KfW), sets high requirements for the energy efficiency of new houses, significantly reducing energy consumption and minimizing environmental impact.

Details of the KFW40+ Standard

The KFW40+ standard stipulates that a building should consume only 40% of the primary energy required for a similar building constructed according to the EH85 standard. Additionally, the building should have only 55% of the heat loss through its enclosing structures. This is achieved through the use of high-quality insulation materials, efficient heating and ventilation systems, and renewable energy sources. Read more about it

What is EH40?

EH40 (Effizienzhaus 40) is part of the energy efficiency standards that define the maximum energy consumption level for new buildings. EH40 means that the building should consume only 40% of the energy required for a standard building. This includes the use of highly efficient heating, ventilation, and air conditioning systems, as well as renewable energy sources such as solar panels and heat pumps.

Thermal Conductivity Coefficient (U-value)

To meet the KFW40+ and EH40 standards, it is necessary to ensure a low thermal conductivity coefficient (U-value) for various building elements. Specifically:

• External walls: U-value between 0.10 and 0.12 W/m²K.

• Roof: U-value around 0.11 W/m²K.

• Windows: Ug-value (thermal conductivity coefficient for glass) no more than 0.6 W/m²K.

How We Achieve These Standards at TK Standard

At TK Standard, we use the latest technologies and materials to ensure high energy efficiency in our houses:

High-quality insulation: We use innovative insulation materials that provide low thermal conductivity for walls, roofs, and floors.

Energy-efficient windows: Our houses are equipped with triple-glazed insulating windows, significantly reducing heat loss.

Heating and ventilation systems: We use modern heating and ventilation systems that ensure efficient energy use and comfortable living conditions.

Renewable energy sources: Our houses can be equipped with solar panels and heat pumps, reducing the consumption of traditional energy sources.

Latest Requirements of European Countries, Particularly Germany

European countries, especially Germany, are actively implementing new energy efficiency standards for buildings. Since 2020, all new buildings in the EU must comply with the "nearly zero energy consumption" (NZEB) requirements. From 2028, new buildings owned by public authorities, and from 2030, all other new buildings, will be required to meet the "zero emissions" standard.
