The terms energy efficiency and energy saving identify distinct sets of interventions, aimed at achieving significant improvements in technical, economic and consumption terms in the energy management of buildings.
In buildings, the assessment of the factors of production and energy consumption (energy diagnosis) is essential for the choice of the most effective interventions in order to improve the use of the built organism. The energy diagnosis takes into account the integrated building / system system, consisting of the building envelope and technological systems (winter heating, summer air conditioning, lighting, ventilation, etc.).
Today, investing in quality (efficiency / energy saving) is worthwhile even in terms of “real estate marketing”, but above all today, classification is proposed as a solution to objectively indicate the quality levels of buildings.
