\nThe construction and building sector is one of the largest consumers of energy. Sustainable construction methods that use efficient materials significantly reduce energy consumption and conserve valuable resources. Choosing the right building materials plays a key role in this.\n<\/div>\n<\/div>

\nResource Efficiency in Building Construction\n<\/h2>
\nOne-third of Germany\u2019s final energy consumption is accounted for by heating and hot water production. To fulfill our responsibility to future generations\u2014not only with regard to finite energy resources\u2014we must ensure a high level of material efficiency in our use of resources during construction.\n<\/div>\n<\/div>
\n \n \n\t\n\n\n\n
\nResource efficiency is therefore only possible if we succeed in combining energy efficiency and material efficiency!\n<\/div>
\nThe construction sector is characterized by long service lives and high investment costs. The targeted use of material resources makes it possible to minimize energy consumption over many decades while also contributing to well-being.\n<\/div>
\nThe extent of the savings is illustrated in the following chart, which compares the average energy consumption for the extraction, production, transportation, and demolition of building materials with the energy savings over a hypothetical service life of 40 years.\n<\/div>\n<\/div>

What's surprising is that these values apply to just one square meter of wall.<\/p>

Here's an example:
The primary energy required to manufacture thermal insulation with a U-value of 0.21 W\/m\u00b2K averages 70 kWh. However, the savings achieved over 40 years amount to 4,101 kWh of heating energy\u2014more than 50 times as much (compared to the average insulation standard).<\/p>

For a 150 m\u00b2 facade, this corresponds to energy savings of 615,150 kWh over 40 years\u2014which is roughly equivalent to 61,500 liters of light heating oil. Compared to the current German thermal insulation standard, this is equivalent to the savings achieved by a hollow-core brick wall.<\/p>\n<\/div>\n<\/div><\/div>

\nThe Product Life Cycle of Insulation Materials\n<\/h2>
\nIn addition to the potential energy savings offered by thermal insulation, the overall life cycle of a building material also plays a crucial role.
