The energy efficiency of buildings is a major concern in the construction and renovation sector. This can have an impact on various aspects of a building, such as thermal insulation. Building professionals are turning to software that enables them to make thermal insulation calculations.
These innovative tools facilitate precise assessment of critical aspects of thermal insulation, including heat loss calculations, determination of thermal bridges and evaluation of thermal resistance. They enable detailed digital simulation of heat flows within structures, contributing to comprehensive and reliable energy audits. Find out all you need to know about thermal insulation calculation software by reading on.
Thermal insulation calculation principles
Calculating the heat loss of a dwelling is a rather complex process that takes several key factors into account:
Wall analysis
Air renewal
Thermal bridges
The basic method is based on the temperature difference between the inside and outside of the dwelling, multiplied by the surface area or volume concerned, and the thermal transmittance of the materials.
According to a study by ADEME, losses through vertical walls account for around 20-25%, and those through the roof can reach 25-30% of total losses in a poorly insulated building. Thermal bridges, where insulation is less effective, also contribute significantly to energy losses. The accuracy of this calculation is crucial to defining heating requirements and implementing effective insulation measures.
