In Europe, buildings represent approximately 40% of the total energy consumption and 36% of the CO2 emissions and are therefore the single largest energy consumer in Europe, ahead of industrial sectors. A house is considered as passive when its energy demand is lower than 15 kWh/ m²/ year and its total energy consumption (including cooling, domestic hot water, use of devices and technical equipment, lighting, ventilation and consumption linked to building use) does not exceed 120 kWh/ m²/ year. The RT 2012 norm considers a building as “low energy” as soon as its consumption is limited to 50 kWh/ m²/ year, including lighting, heating, air conditioning and hot water. The RT 2012 norm is based on renewable energy. To reduce energy consumption and building emissions, environmentally friendly and renewable energy sources (solar panels, heating pumps...) are efficient solutions. All Palmatin constructions are complying with the RT 2012 norm and reach the energy efficiency requirements.
