The difference lies mainly in the degree of insulation and the proportion of sustainably generated energy. An A label can be achieved with good insulation and an efficient installation. For A+++, more is needed: a large proportion of the energy must be generated sustainably, for example with solar panels and a heat pump.
The energy label is determined based on the fossil energy consumption of the home, expressed in kWh/m² per year. For an A label, this value is between 105 and 160 kWh/m² per year. With good insulation, an A label is easily achievable. Homes built after 1991 often already have sufficient basic insulation to fall into this category. Solar panels are therefore not necessarily required to achieve an A label.
