An energy-efficient building creates comfortable living conditions with the least possible amount of energy consumption maximizing efficiency in the use of resources. Moreover, energy-efficient buildings decrease indoor air pollution as they provide cleaner combustion and better ventilation than conventional buildings. Achieving energy efficiency in buildings is a cheap way to reduce climate change and health problems.
With the cost of energy increasing and the energy crisis being an impending reality, the need to provide energy-efficient building designs becomes more important. Buildings are responsible for around 40% of energy consumption and 36% of CO2 emissions in the EU, making them the single largest energy consumer in Europe.
The building sector is crucial for achieving the EU's energy and environmental goals. To boost the energy performance of buildings, the EU has established a legislative framework that includes the Energy Performance of Buildings Directive 2010/31/EU and the Energy Efficiency Directive 2012/27/EU.
Together, the directives promote policies that will help - achieve a high energy-efficient and decarbonised building stock by 2050; create a stable environment for investment decisions; enable consumers and businesses to make more informed choices to save energy and money.
The adoption of energy efficiency techniques during the construction and operation of buildings would play a crucial role in the creation of sustainable cities in the future.
