Choice of building materials

In the building industry, energy efficiency is linked to functionality and even construction materials. Energy efficiency makes it possible to reduce energy consumption for a given use, while preserving the environment. The need for energy in a building is not as trivial as it may seem; it is both judicious and complex.Insulating external walls can save around 22.7%, roof insulation 37.3%, while floor insulation has a negative impact on energy performance.
