These buildings are designed with high energy efficiency standards in mind and, although they require some external energy to operate, the amount is minimal compared to conventional standards.<\/p>\n<p>By 2030, the EU plans to move from these to zero-emission buildings (ZEB), which will obtain 100% of their energy from renewable sources.<\/p>\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"How_is_a_Homes_Energy_Efficiency_Calculated\"><\/span>How is a Home&#8217;s Energy Efficiency Calculated?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p>The energy efficiency of a home is generally calculated by dividing the energy consumed by its usable area, known as specific energy consumption. However, this calculation is not always sufficient, as building materials also require energy in their manufacture, making the problem more complex and requiring a more comprehensive approach.<\/p>\n<p>ISO 50001, a voluntary standard, is one of the main standards used to measure energy efficiency in buildings. This standard employs different indicators that measure energy consumption (such as lighting, ventilation, heating, cooling, and hot water production) over a specific period. The more energy used in the home, the less efficient it is.<\/p>\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3><span class=\"ez-toc-section\" id=\"What_are_the_Two_Main_Indicators_of_a_Homes_Energy_Efficiency\"><\/span>What are the Two Main Indicators of a Home&#8217;s Energy Efficiency?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div style=\"height:40px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<p>Annual CO2 emissions, expressed in kg\/m2 of usable surface area of the home.<\/p>\n<p>Annual consumption of non-renewable primary energy, expressed in kWh\/m2 of usable surface area of the home.<\/p>\n<p>We must keep in mind that energy efficiency at home will help us make our home more efficient in resource management and, therefore, will generate a more comfortable space.
